LiTime (Ampere Time) 12V 100Ah Lithium Iron Phosphate LiFePO4 Deep Cycle Battery
LiTime (formerly known as Ampere Time) 12V 100Ah Lithium Iron Phosphate LiFePO4 battery is a deep cycle battery intended for marine, light industrial, automotive, off-the-grid, and other similar applications.
Thanks to its ultra-light and compact design, the LiTime (Ampere Time) 12V 100Ah LiFePO4 battery is one of the most popular batteries for use as a trolling motor battery, inverter battery, solar battery, RV battery, and similar. But, like any other LiFePO4 battery, it has to be recharged using dedicated 12V lithium battery chargers or chargers with dedicated 12V lithium battery charging mode.
Updated: February 9, 2023.
LiTime (Ampere Time) 12V 100Ah Lithium Iron Phosphate LiFePO4 Features and Specifications
LiTime (Ampere Time) 12V 100Ah LiFePO4 deep cycle battery features physical dimensions of (L x W x H) 13 x 6.82 x 8.48 inches (~33 x 17.3 x 21.5 cm) and belongs to the BCI Group 31.
Note: battery height with its M8 battery terminals is 9.3 inches (~23.6 cm).
The battery is much lighter than the typical group 31 battery. it weighs just 24.25 pounds (~11 kg) and ensures great weight savings when lead-acid deep cycle batteries are replaced with the battery pack based on this or similar but larger Ampere Time batteries.
LiTime (Ampere Time) 12V 100Ah lithium battery is based on four 3.2V prismatic LiFePO4 cells, monitored and controlled by the built-in Battery Management System (BMS), which protects the battery from overcharge, over-discharge, over-current, and short circuit.
The nominal voltage of the battery is 12.8V, with a maximum charging voltage of 14.6V and a minimum voltage of ~10V.
Note: when the discharge current is kept at ~0.1C (~10 Amps), the output voltage is at least 12.8V for ~95% of the discharge time, leading to excellent energy efficiency. Even when the discharge current is increased to 1.0C, energy efficiency is much better than the energy efficiency of similar lead-acid batteries.
The charging temperature range is between 0°C and 50°C while discharging temperature range is between.20°C and 60°C.
LiTime (Ampere Time) 12V 100Ah lithium battery supports 4000 charging/discharging cycles. the number of charging and discharging cycles also depends on the battery use, age, average temperature, and similar.
The expected lifetime of the battery is up to 10 years, while the battery itself comes with a very nice 5-year limited warranty.
The maximum continuous discharging current is 100 Amps, with 280 Amps being allowed for 5 seconds. Although such currents are enough even for starting smaller internal combustion engines, such use is not recommended. this is a very finely tuned deep-cycle battery and, as such, should be used.
The maximum continuous charging current is 100 Amps, allowing the user to recharge the battery quickly.
Personally, to prolong the battery life, the maximum charging current should be kept in the 20-30 Amps range. this prolongs the charging time but also decreases the load on the battery.
The built-in BMS also allows the LiTime (Ampere Time) 12V 100Ah lithium battery to be connected in parallel and series. up to 4 batteries may be connected in series (voltage up to 48V. actually up to 51.2V), and up to 4 batteries may be connected in parallel (capacity up to 400Ah).
Note: when connecting the batteries in series and/or parallel, always use exactly the same battery model from the same manufacturer, preferably from the same batch in order to avoid any imbalances and other issues with a newly formed battery pack.
How to Charge the LiTime (Ampere Time) 12V 100Ah Lithium Battery
As said before, the LiTime (Ampere Time) 12V 100Ah lithium battery supports a maximum charging current of 100 Amps. But, to prolong the battery lifetime, a charging current in 20-50 Amps may be used.
LiTime (Ampere Time) offers a dedicated 12V 20Amps lithium battery charger, optimized for charging deep cycle 12V LiFePO4 batteries.
LiTime (Ampere Time) 12V 20Ah LiFePO4 battery charger features an input voltage of 100-240 volts and is a dedicated lithium battery charger. it can’t be used to charge lead-acid batteries.
It features a Constant Current/Constant Voltage (CC/CV) charging algorithm with a maximum charging voltage of 14.6V (±0.2V) and several safety features to protect the battery and the charger itself, including over-temperature protection, reverse polarity protection, over-voltage protection, and short-circuit protection.
When charging 12V 100Ah lithium battery, for example, from 80% DoD to 20% DoD, this battery charger requires some 3-3.5h. When the battery is completely discharged and must be completely recharged, this battery charger requires some 5.5-6h to complete the task.
For more information about this charger, feel free to check the LiTime (Ampere Time) 12V 20Ah LiFePO4 Battery Charger Amazon link (link opens in the new window).
However, if charging time is important, stronger charging currents can be used, with charging currents up to 50 Amps, since the manufacturer claims that charging currents of up to 100 Amps are allowed.
There are several suitable 25-50 Amps battery chargers on the market. However, NOCO Genius Pro 25 and NOCO Genius Pro 50 are highly recommended.
Both battery chargers support the charging and repairing of the 6V, 12V, and 24V batteries, including wet/flooded, Gel-Cell, and AGM lead-acid batteries and of course, lithium batteries.
Also, both units support charging smaller batteries with weaker currents (NOCO Genius Pro 25: down to 5A, NOCO Genius Pro 50: down to 10A), come with a set of safety features, both are able to detect deeply discharged batteries, etc.
As such, these chargers are not cheap, but neither are the batteries they are intended to charge.
For more information about these battery chargers, feel free to check the NOCO Genius Pro 25 and NOCO Genius Pro 50 Amazon links (links open in the new window).
LiTime (Ampere Time) 12V 100Ah Lithium Battery As Inverter Battery
With its nominal voltage of 12.8V and 100 Amps continuous discharge current (and 280A for 5 seconds!), the LiTime (Ampere Time) 12V 100Ah lithium battery can be used as an excellent inverter battery.
For example, when a 1000W inverter with 85% efficiency is connected to the battery, the inverter draws ~1180 watts from the battery, which should not be a problem for a new, fully charged Ampere Time 12V 100Ah lithium battery for at least one hour.
Also, thanks to the 280A/5s pulse current, the battery can provide enough energy for power surges up to 3000 watts.
So, if You have a power inverter with a maximum output power of 1000W and surge output power up to 3000W, consider Ampere Time 12V 100Ah lithium battery as your next inverter battery.
LiTime (Ampere Time) 12V 100Ah Lithium Battery As Trolling Motor Battery
LiTime (Ampere Time) 12V 100Ah battery is often used as a lightweight trolling motor battery, either to power 12V trolling motors or connected in parallel and/or series to create battery packs with larger capacity and/or higher voltage.
With a typical 55 lbs trolling motor requiring up to 50 Amps continuously and up to 25-30 Amps at half throttle, LiTime (Ampere Time) 12V 100Ah battery can power such motor for:
Note: If You are using your electric trolling motor at full throttle most of the time, your trolling motor is seriously underpowered and must be replaced with a stronger unit for many reasons, additional safety being just one of them.
Long Story Short: LiTime (Ampere Time) 12V 100Ah lithium battery is a very popular BCI Group 31 LiFePO4 battery. it is a versatile battery that can withstand a large number of charging/discharging cycles and can provide a relatively strong current.
Also, it supports 4P4S connections (up to 4 batteries in parallel, up to 4 in series) for making larger battery packs.
As such, this battery is the preferred choice for applications where an ultralight battery that cycles well is required. trolling motor battery, RV house battery, inverter battery, solar battery, electric vehicles, off-the-grid applications, etc.

Dear Customer, 1)Yes, 1 charger could works for 2pcs Redodo 12V(12.8V) 100Ah LiFePO4 batteries which connected in series. One 12V 100Ah LiFePO4 battery built-in 100A BMS, which could support 100A max. continuous charge/discharge current, 1280W max. continuous load power, and 1280Wh max. energy. Connected 2pcs of those 100Ah batteries in series will build a 24V(25.6V) 100Ah battery system, which could support 100A max. continuous charge/discharge current, 2560W max. continuous load power, and 2560Wh max. energy. Regarding the charger for the 24V 100Ah battery system, we recommend a dedicated LiFePO4 battery charger, the DC charging voltage should be between 28.4V~29.2V and charging current less than 100A (usually, we recommend the current of 0.2C, which means 20A, and it will take around 5hrs to fully charge the battery system). 2)Here are two steps are necessary in order to reduce the voltage difference between batteries before connection, and through these, the battery system can perform the best of it in series or/ and in parallel. Step① fully charge your batteries separately. Step② connect your batteries one by one in parallel, and leave them together for 12~24hrs. And then, you can connect your batteries in series or/ and in parallel to build your own battery system. BTW, for charging one 12V 100Ah LiFePO4 battery, we recommend a dedicated LiFePO4 battery charger, the DC charging voltage should be between 14.2V~14.6V and charging current less than 100A. To help you analyze and optimize your battery system precisely, we welcome you to contact us on service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information.
Hi, for safety reasons, we don’t suggest connecting 5 or 6 pieces of the Redodo 100Ah batteries in series. Our 12V 100Ah LiFePO4 battery supports up to 4 identical batteries for up to: 48V 100Ah battery system (in series) 12V 400Ah battery system (in parallel) And we recommend connecting MAX. 16pcs of Redodo 12V(12.8V) 100Ah LiFePO4 batteries in 4P 4S to build a 48V(51.2V) 400Ah battery system(“P” refers to parallel, “S” refers to series). To help you analyze and solve your question about the battery connections more specifically, we welcome you to contact us at service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information.
Hi, at the beginning, we had set up the low temperature cut-off function for Redodo 100Ah LiFePO4 battery, but later many customers responded that they also want to discharge it under 32°F/0°C. After careful research, our team has decided to block this function. Some of our customers who live in the cold areas who are happy to use our batteries too, because it can discharge well and their loads can work under low temperature. If they need to charge the battery below 32°F/0°C. they told us that they choose a dedicated LiFePO4 battery charger with a low-temp cut-off function, or take the batteries to the house where the temperature is higher than 32°F/0°C. We will have the LiFePO4 batteries that have low temperature protection in the near future.
Should I leave lifePO4 battery connected to charger after it has been fully charged, and will not be used for awhile?
Hi, usually, you can leave LiFePO4 battery connected to charger after it has been fully charged for a while if your battery charger has automatic power off function. Redodo LiFePO4 battery also has over-charging protection too. But for the safety reasons, we suggest that disconnect the battery with the charger once it is full charged.
I have two 12v 100ah batteries connected together. can i add one 12v 200ah battery to this, will the bms match up or do i need to add two 12v 100ah?
No, we do not suggest you to connect 12v 200ah battery to the battery system of 212V 100Ah battery. Although Redodo 12V 100Ah LiFePO4 battery and Redodo 12V 200Ah LiFePO4 battery have built-in 100A BMS, the capacities of two battery models are different. To connect in series or /and parallel, batteries should meet the below conditions: a. identical batteries with the same battery capacity (Ah) and BMS (A); b. from the same brand (as lithium battery from different brands has their special BMS); c. purchased in near time (within one month) So if you want to expand your battery system, we suggest you to add 212V 100Ah battery.
Hi, we do not recommend to connected the Redodo 12V 100Ah battery and 200Ah battery together. Here are two main reasons why we don’t suggest connecting batteries with different capacities: 1) After parallel connection of batteries with different capacities, the current of 200Ah is twice as large as that of 100Ah when charging/discharging at the same time. 2) The internal resistance of the 200Ah battery is 2-4mΩ, and that of the 100Ah battery is 7-9mΩ. When the batteries with different impedances are connected in parallel, it is possible to damage BMS after long-term use. To connect in series or/ and in parallel, batteries should meet below conditions: a: the same battery capacity(Ah) and same BMS b: from same brand(as lithium battery from different brands has their special BMS) c: purchased in near time(within one month) d: from same types of battery
Can these batteries be mounted on their side or does the orientation of the terminals always have to be upright?
Hi, we suggest that you place Redodo 12V(12.8V) 100Ah LiFePO4 battery with the terminal bolts upward. If you have more than one Redodo 100Ah LiFePO4 battery, please avoid their post bolts having direct contact when mounting them. To help you analyze and solve your question about the batteries more specifically, we welcome you to contact us at service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information.
Hi, Redodo 12V 100Ah LiFePO4 battery have cells which get certificate from UL and the protection class is IP65 and the battery quality is Grade-A.
Hi, 1)We don’t suggest that to connect the Redodo 12V(12.8V) 100Ah LiFePO4 batteries with any lead-acid batteries because they are totally different: 1. The LiFePO4 batteries and the lead-acid batteries own different charge/discharge modes; 2. The voltages of the LiFePO4 batteries and the lead-acid batteries are different(even if they are written in 12V); 3. The LiFePO4 batteries are built in BMS while the lead-acid batteries are not. 2)To connect in series or/ and in parallel, batteries should meet the below conditions: a: the same battery capacity(Ah) and same BMS b: from the same brand(as lithium battery from different brands has their special BMS) c: purchased in near time(within one month) d: from same types of battery To help you analyze and solve your question about the battery connection more specifically, we welcome you to contact us on service@redodopower.com, and we will help you with an in-depth analysis according to your detailed information.
Hi, Yes, for Redodo 12V(12.8V) 100Ah LiFePO4 battery, you can connect 6 batteries to make a 3P2S (P refers to Parallel and S refers to Series) battery system of 24V(25.6V) 300Ah. One Redodo 12V 100Ah LiFePO4 battery built-in 100A BMS, which could support 100A max. continuous charge/discharge current, 1280W max. continuous load power, and has max. 1280Wh energy. The 3P2S battery system of 24V(25.6V) 300Ah could support 300A max. continuous charge/discharge current, 7680W max. continuous load power, and has max. 7680Wh energy.
The Complete Guide to Lithium vs Lead Acid Batteries
When it comes to choosing the right battery for your application, you likely have a list of conditions you need to fulfill. How much voltage is needed, what is the capacity requirement, cyclic or standby, etc.
Once you have the specifics narrowed down you may be wondering, “do I need a lithium battery or a traditional sealed lead acid battery?” Or, more importantly, “what is the difference between lithium and sealed lead acid?” There are several factors to consider before choosing a battery chemistry, as both have strengths and weaknesses.
For the purpose of this blog, lithium refers to Lithium Iron Phosphate (LiFePO4) batteries only, and SLA refers to lead acid/sealed lead acid batteries.
CYCLIC PERFORMANCE LITHIUM VS SLA
The most notable difference between lithium iron phosphate and lead acid is the fact that the lithium battery capacity is independent of the discharge rate. The figure below compares the actual capacity as a percentage of the rated capacity of the battery versus the discharge rate as expressed by C (C equals the discharge current divided by the capacity rating). With very high discharge rates, for instance.8C, the capacity of the lead acid battery is only 60% of the rated capacity. Find out more about C rates of batteries.
Therefore, in cyclic applications where the discharge rate is often greater than 0.1C, a lower rated lithium battery will often have a higher actual capacity than the comparable lead acid battery. This means that at the same capacity rating, the lithium will cost more, but you can use a lower capacity lithium for the same application at a lower price. The cost of ownership when you consider the cycle, further increases the value of the lithium battery when compared to a lead acid battery.
The second most notable difference between SLA and Lithium is the cyclic performance of lithium. Lithium has ten times the cycle life of SLA under most conditions. This brings the cost per cycle of lithium lower than SLA, meaning you will have to replace a lithium battery less often than SLA in a cyclic application.
CONSTANT POWER DELIVERY LITHIUM VS LEAD ACID
Lithium delivers the same amount of power throughout the entire discharge cycle, whereas an SLA’s power delivery starts out strong, but dissipates. The constant power advantage of lithium is shown in the graph below which shows voltage versus the state of charge.
A lithium battery as shown in the orange has a constant voltage as it discharges throughout the entire discharge. Power is a function of voltage times current. The current demand will be constant and thus the power delivered, power times current, will be constant. So, let’s put this in a real-life example.
Have you ever turned on a flashlight and noticed it’s dimmer than the last time you turned it on? This is because the battery inside the flashlight is dying, but not yet completely dead. It is giving off a little power, but not enough to fully illuminate the bulb.
If this were a lithium battery, the bulb would be just as bright from the beginning of its life to the end. Instead of waning, the bulb would just not turn on at all if the battery were dead.
CHARGING TIMES OF LITHIUM AND SLA
Charging SLA batteries is notoriously slow. In most cyclic applications, you need to have extra SLA batteries available so you can still use your application while the other battery is charging. In standby applications, an SLA battery must be kept on a float charge.
With lithium batteries, charging is four times faster than SLA. The faster charging means there is more time the battery is in use, and therefore requires less batteries. They also recover quickly after an event (like in a backup or standby application). As a bonus, there is no need to keep lithium on a float charge for storage. For more information on how to charge a lithium battery, please view our Lithium Charging Guide.
HIGH TEMPERATURE BATTERY PERFORMANCE
Lithium’s performance is far superior than SLA in high temperature applications. In fact, lithium at 55°C still has twice the cycle life as SLA does at room temperature. Lithium will outperform lead under most conditions but is especially strong at elevated temperatures.
COLD TEMPERATURE BATTERY PERFORMANCE
Cold temperatures can cause significant capacity reduction for all battery chemistries. Knowing this, there are two things to consider when evaluating a battery for cold temperature use: charging and discharging. A lithium battery will not accept a charge at a low temperature (below 32° F). However, an SLA can accept low current charges at a low temperature.
Conversely, a lithium battery has a higher discharge capacity at cold temperatures than SLA. This means that lithium batteries do not have to be over designed for cold temperatures, but charging could be a limiting factor. At 0°F, lithium is discharged at 70% of its rated capacity, but SLA is at 45%.
One thing to consider in cold temperature is the state of the lithium battery when you want to charge it. If the battery has just finished discharging, the battery will have generated enough heat to accept a charge. If the battery has had a chance to cool down, it may not accept a charge if the temperature is below 32°F.
BATTERY INSTALLATION
If you have ever tried to install a lead acid battery, you know how important it is to not install it in an invert position to prevent any potential issues with venting. While an SLA is designed to not leak, the vents allow for some residual release of the gasses.
In a lithium battery design, the cells are all individually sealed and cannot leak. This means there is no restriction in the installation orientation of a lithium battery. It can be installed on its side, upside down, or standing up with no issues.
BATTERY WEIGHT COMPARISION
Lithium, on average, is 55% lighter than SLA. In cycling applications, this is especially important when the battery is being installed in a mobile application (batteries for motorcycles, scooters or electric vehicles), or where weight may impact the performance (like in robotics). For standby use, weight is an important consideration in remote applications (solar fields) and where installation is difficult (up high in emergency lighting systems, for example).
SLA VS LITHIUM BATTERY STORAGE
Lithium should not be stored at 100% State of Charge (SOC), whereas SLA needs to be stored at 100%. This is because the self-discharge rate of an SLA battery is 5 times or greater than that of a lithium battery. In fact, many customers will maintain a lead acid battery in storage with a trickle charger to continuously keep the battery at 100% so that the battery life does not decrease due to storage.
SERIES PARALLEL BATTERY INSTALLATION
A quick and important note: When installing batteries in series and parallel, it is important that they are matched across all factors including capacity, voltage, resistance, state of charge, and chemistry. SLA and lithium batteries cannot be used together in the same string.
Since an SLA battery is considered a “dumb” battery in comparison to lithium (which has a circuit board that monitors and protects the battery), it can handle many more batteries in a string than lithium.
The string length of lithium is limited by the components on the circuit board. Circuit board components can have current and voltage limitations that long series strings will exceed. For example, a series string of four lithium batteries will have a max voltage of 51.2 volts. A second factor is the protection of the batteries. One battery that exceeds the protection limits can disrupt the charging and discharging of the entire string of batteries. Most lithium strings are limited to 6 or less (model dependent), but higher string lengths can be reached with additional engineering.
There are many differences between SLA and lithium battery performance. In most instances, lithium is the stronger battery. However, SLA should not be discounted as it still has an edge over lithium in some applications, like long strings, extremely high rate of discharge, and cold temperature charging.
