Can I Use 48v Battery With 36V E-Bike Motor?
In the ebike industry, unlike more mature industries, there’s a distinct lack of standardization. This means that components from one e-bike might use different technology, voltages, and connectors than similar parts from another e-bike. Replacing, upgrading, or adding electronic parts to e-bikes can get complicated, and fast.
If you’re building your own bike, you want to replace a battery, or you just have a spare lithium battery you’re thinking about using on your e-bike, you might be wondering how compatible these different parts are with each other. So can you use a 48v battery with your 36v motor?
You can use a 48-volt battery with a 36-volt e-bike motor as long as the controller is compatible with 48-volt (or higher) setups, and the electric motor is compatible with and does not overheat by the increased Wattage (volt x amps) output generated by the 48-volt battery.
Let’s go over all of the reasons why this might not work from an electronics perspective and talk about what you should look for before plugging in a battery that’s not designed for your bike.
Can I Use 48v Battery With 36v Motor?
Yes, you can use a 48-volt battery with your 36-volt e-bike motor, but it might not be a good idea. Your motor probably will work with a wide range of voltages and is unlikely to be the source of any problems you run into.
Increasing the voltage to the motor will increase the rate at which it spins, which can have interesting mechanical implications and will cause the motor to generate more heat, but it won’t break anything short-term. In fact, some people deliberately over-volt their motors in order to get their bikes to go faster.
Before throwing a high voltage battery on your e-bike, you’ll want to do a bit of research. First, if you can, try to figure out the exact specifications of your motor and see what voltage ranges it was designed for.
If you’ve got a motor that’s designed to be used at 36 volts, the 33% increase in voltage to 48 volts is probably fine. If you’ve got a motor that’s designed to be used at a lower voltage, however, it’s probably being stretched already when it’s pushed to 36 volts. In this case, going to 48 volts is much more likely to cause issues.
Alternately, if you’ve got a motor that’s being used under its rated voltage, going to 48 volts will be totally fine.
Second, and more importantly, you’ll want to examine the other components of your bike and make sure that they’re compatible with your 48v battery.
Your motor will generate more heat and spin faster when it’s exposed to more voltage, but your controller is much more sensitive to changes in how electricity flows through your bike. This means that the controller is the component you’ll want to examine first if you’re trying to put a 48v battery on your bike.
Can I Use A 48v Battery With a 36v Controller?
You might be able to use a 48v battery with your 36v e-bike controller, but you’ll need to do some research first. Most modern e-bike controllers are designed for a very big range of voltages, so a 36v controller is a bit of an oddity.
Look for the model number of your controller (often found on a sticker on the unit) and try to find out the full range of voltages it’s compatible with. If the range ends in 36v (24-36v, for example), you’ll definitely want to avoid using a 48v battery. If it’s 36-48v or higher, however, you should be fine to plug in your big battery.
If your controller isn’t listed as being compatible with 48v or higher setups, do NOT plug the battery in. Controllers tend to have sensitive components like capacitors that will break very quickly when exposed to a higher voltage than they’re designed for.
Plugging a 48v battery into your 36v controller and turning on your bike has a very high chance of blowing your capacitors and breaking your controller.
What Happens When I Use A 48v Battery With A 36v Motor?
The terms “volts” and “amps” describe the flow of electricity through a system. If we think of electricity as water running through pipes, voltage describes the pressure of the water in the pipe, while amperage describes the volume of water flowing through the pipe.
A big, wide pipe with slow flow would have high amps and low voltage, while a thin pipe with high pressure would have high voltage and lower amps.
Your motor needs both pressure and volume in order to function. The more electricity it gets, the more torque it can generate. This means that in order to get up hills or start from a stop you’ll want to increase the amps that your motor has access to, but not necessarily the voltage.
If you want it to spin fast, however, it needs a supply of high-pressure, fast-moving electricity in order to quickly power and de-power the magnets that make your motor work. This requires a lot of voltage.
Motors are sensitive to changes in both amps and volts, but they’re generally totally safe to operate as long as the two don’t combine dangerously.
To continue with the water analogy, this means that your motor doesn’t care if you’ve got a thin pipe with high pressure or a thick pipe with low pressure. Your motor will simply produce lots of torque at low speeds with one setup and high speeds with less torque with the other setup.
If you give it a thick pipe with high pressure, however, you risk exposing your motor to more total electricity than it can safely handle, which could cause problems. In other words, you’re mostly worried about watts, or voltage times amps, not the distribution between the two. This is why many people who overvolt their motors will modify their setup to reduce amperage, keeping their motors safe.
As mentioned above, supplying your motor with more volts than it is designed for will cause it to generate more heat. This often means that you’ll reduce the lifespan of your motor, although not necessarily by a huge amount.
Motors are designed to handle some amount of heat generation and are usually over-engineered, meaning that they’ll have generous tolerances in terms of their ability to handle the voltage, dissipate heat, and deal with wear and tear.
In practice, you’ll probably be fine with a modest increase in volts of 25-35%, especially if you don’t run your motors at peak output all the time. Again, though, be mindful of your total watt output and make sure that you’re not pushing an unsafe amount of energy into your motors.

The Power of Voltage: How Battery Voltage Affects Your E-Bike’s Performance
Electric bikes, or e-bikes, have gained immense popularity in recent years. They offer a sustainable and efficient alternative to traditional bikes, allowing riders to go farther and faster with less effort. However, e-bikes rely on batteries to power their electric motors, which means that the voltage of the battery is a crucial factor in determining their performance.
In this article, we will explore the significance of battery voltage for e-bike performance. We will answer common questions related to electric bike battery voltage, including how it affects speed, acceleration, and range, and compare the performance of different voltage options.
By the end of this article, you will have a better understanding of the power of voltage and how it can impact your electric bike riding experience.
Understanding Battery Voltage
Battery voltage is a crucial aspect that greatly influences the performance of an e-bike. It refers to the measure of electrical potential difference between two points in a circuit and is expressed in volts (V). In simpler terms, voltage can be understood as the force that drives the flow of electricity in your e-bike’s electrical system.
To put it in perspective, think of voltage as the “push” or “pressure” that propels the electrical current through your e-bike. Just like water pressure in a hose determines how forcefully water flows, battery voltage determines how efficiently electrical energy is delivered to power the various components of your e-bike, such as the motor.
Acceleration
Along with speed, battery voltage also affects the acceleration of an e-bike. A higher voltage battery delivers more power to the motor, resulting in quicker acceleration. The increased power output allows the motor to respond more energetically when you start pedaling or engage the throttle, resulting in a more responsive and dynamic riding experience.
Range
While higher voltage can enhance speed and acceleration, it’s important to consider how it impacts the e-bike’s range. The capacity of an e-bike battery is measured in amp hours (Ah) or watt hours (Wh), and voltage is only one piece of the equation. Higher voltage batteries tend to have a lower capacity, which means they may offer a shorter range compared to lower voltage batteries with a higher capacity. Therefore, it’s crucial to consider the balance between voltage and capacity when choosing an e-bike battery to ensure it meets your specific range requirements.
Addressing the question of whether a higher voltage battery will make an electric bike faster, the answer is yes, it can contribute to increased speed. However, it’s important to consider other factors such as motor power, rider weight, terrain, and legal restrictions in your area.
Furthermore, when evaluating battery capacity, amp hours (Ah) and watt hours (Wh) are crucial indicators. Amp hours represent the total amount of charge a battery can deliver in one hour, while watt-hours measure the total energy capacity of the battery. These values give you an idea of the battery’s endurance and how long it can provide power to your e-bike.
Choosing the Right Voltage
Selecting the appropriate voltage for your electric bike depends on your specific needs and preferences. If you prioritize longer ranges over higher speeds, a 36V battery with a higher capacity might be a suitable choice. On the other hand, if you seek a more powerful and faster ride, a 48V battery could better meet your requirements. Consider your riding style, terrain, and the level of assistance you desire to determine the voltage that suits your needs best.
When choosing a voltage option for your e-bike battery, it’s essential to consider factors beyond just voltage, such as battery capacity, motor power, and the overall performance you expect from your e-bike. Evaluating the combination of these factors will help you select the optimal voltage that aligns with your riding goals.
In the next section, we will delve into the topic of battery voltage and its impact on motor power, discussing the relationship between voltage and the overall power output of an e-bike.
Battery Voltage and Motor Power
The relationship between battery voltage and motor power is a critical factor in understanding how an e-bike performs. In this section, we’ll explore the wattage rating of a motor, the importance of current (amps), and the impact of voltage on different types of motors.
Wattage Rating and Current: The wattage rating of a motor indicates its power output, which is determined by the voltage and current it receives. In simple terms, power (watts) is calculated by multiplying the voltage (volts) by the current (amps). Therefore, both voltage and current play a significant role in determining the motor’s power and performance.
Impact on Mid-Drive and Hub Motors: Mid-drive and hub motors are two common types of e-bike motors, and they can be influenced by battery voltage in different ways.
- Mid-Drive Motors: Mid-drive motors are located near the bike’s crankshaft, providing direct power to the drivetrain. These motors typically operate at higher voltages and lower currents. The higher voltage allows mid-drive motors to generate more torque, making them well-suited for tackling steep inclines or off-road terrain.
- Hub Motors: Hub motors, on the other hand, are integrated into the wheel hub and provide direct propulsion. They generally operate at lower voltages but higher currents. Higher voltage in hub motors can lead to increased top speed and better overall performance, especially on flat surfaces or urban commuting.
Higher Voltage and Power Performance: The question often arises whether higher voltage translates to more power and better performance. While voltage is a significant factor in determining power output, it is not the sole determinant. Other factors, such as motor efficiency, controller technology, and overall system design, also play vital roles.
Higher voltage can allow for higher power output, which can result in increased speed, acceleration, and overall performance. However, it’s important to note that simply increasing the voltage without considering other components may not always lead to a significant improvement in performance. It’s crucial to have a well-designed system that takes into account the overall power requirements and ensures optimal compatibility between the battery, motor, and controller.
In the next section, we will discuss the factors that affect e-bike battery life, including usage patterns, charging practices, and environmental conditions to optimize the performance and longevity of an e-bike battery.

We have collected and sorted out some information about 48V lithium batteries, and will take you an in-depth understanding of 48V lithium batteries!
Perfect Energy Storage
2 times battery life, consumes 50% less space, needs no maintenance takes 60% less recharge time
Off-grid solar systems have actually been around for a very long time, and the original typical systems were mostly all 12V. We obtain a lot of consumers questioning why our systems are all at least 24V or 48V because they’re utilized to 12V as the criterion of RV’s and also off-grid homes. For small systems, we can concur that 12V could still be ideal, but for medium, to large projects consumers are transitioning over to utilizing 24V or 48V for economical, more efficient setups. Higher voltage battery pack means that it can support larger solar arrays.
What is A 48V Lithium-ion Battery？
The single battery on the market is generally around 3.7v, but many times the operating voltage range is a little larger and there is clearly a problem of insufficient voltage. At this time to increase the battery voltage battery pack and modular battery comes along, and in the many high voltage battery, 48v lithium-ion batteries are commonly used.
Compared with lead-acid batteries, 48V lithium-ion batteries have the advantages of small size, light weight, strong temperature adaptability, high charging and discharging efficiency, safety and stability, long service life, energy saving and environmental protection.
48V lithium-ion batteries can be divided into ternary lithium batteries, lithium iron phosphate batteries, lithium titanate batteries according to the cathode material.
V Lithium ion Battery Price
48V lithium-ion battery is made by combining multiple lithium cells by connecting them in series and parallel, because the efficiency and life of the battery is not very good if the manufacturing of a single cell is a 48v lithium battery.
V lithium-ion battery price estimation formula
Single lithium battery cell price x (3.2 ~ 3.7V n = 48v) m (the number of cells in parallel) protection plate price shell price auxiliary material price General single lithium cell voltage of 3.2 ~ 3.7V, its price will vary because of the different materials and processes used in the production of lithium battery manufacturers.
V Lithium-ion Battery Protection Board
48V lithium-ion battery protection board, i.e. the circuit board that plays a protective role. It is mainly composed of electronic circuits, which can accurately monitor the voltage of the battery cell and the current of the charging and discharging circuit at all times under the environment of.40℃ to 85℃, and control the on/off of the current circuit in time.
Li-ion battery protection board can play the role of charging and discharging protection for series and parallel connected battery pack, and at the same time can detect the over-voltage, over-current, over-temperature, under-voltage and short-circuit status of each single battery in the battery pack to prolong the service life of the battery and avoid the damage of the battery due to over-discharge. Lithium battery protection board is an indispensable component of lithium battery.
V Lithium-ion Battery BMS
The 48V Li-ion battery management system (BMS) determines the status of the entire battery system by detecting the status of each individual cell in the Li-ion battery pack, and implements corresponding control adjustments and strategies for the Li-ion battery system based on their status to achieve charge and discharge management of the Li-ion battery system and each individual cell to ensure safe and stable operation of the Li-ion battery system.

RS232 and CAN bus interfaces are provided to read all the information on the Li-ion battery management system directly on the computer.
V Lithium ion Battery use Precautions
Lithium-ion battery stored for a long time without use, should be maintained at 50%-60% charge state, should be replenished once every 3 months, and should be charged and discharged once every six months.
During transportation, care should be taken to prevent moisture and humidity, and avoid extrusion and collision to avoid damage to the lithium-ion battery.
In low temperature, it should not be lower than 0°C. Storage at a temperature of 5°C to 10°C is optimal.
Prohibit the use or placement of lithium-ion batteries under high temperature (hot sunlight or very hot car), otherwise it may cause battery overheating, fire or functional failure, shortened life.
Prohibit storage in places with strong static electricity and strong magnetic fields, otherwise it is easy to destroy the battery safety protection device, bringing unsafe hidden danger.
If the lithium-ion battery emits an odor, heat, discoloration, deformation or any abnormalities occur during use, storage or charging, immediately remove the battery from the device or charger and discontinue use.
In the case of lithium-ion batteries, a monthly power loss of 3% to 5% is possible. Self-discharge is temperature dependent and will be higher as the temperature rises.
Complete discharge is the squeezing of a battery until it no longer produces any current. Squeeze out any current. In this case, the voltage will drop to 0 volts. If this state is maintained. A chemical reaction occurs at the electrodes of the battery, rendering it partially or completely unusable.
Lithium-ion batteries can be used in the temperature range of 10°C to 55°C. However, charging can only be done at a battery temperature of 5°C to 45°C.
V Lithium-ion Battery vs. Lead-acid Battery
Energy density by weight
At present, the energy density of lithium battery is generally 200~260wh/g, while that of lead-acid is generally 50~70wh/g. The weight energy density of lithium battery is 3~5 times that of lead-acid, which means that the capacity of lithium battery is three to five times stronger than that of lead-acid battery under the same weight, so lithium battery has absolute advantage in energy storage.
Volume energy density
Since the volume energy density of Li-ion battery is usually about 1.5 times that of lead-acid battery, Li-ion battery is about 30% smaller than lead-acid battery in the same capacity.
Service life
The most popular lithium battery materials are lithium ternary and lithium iron. For example, ternary lithium batteries usually have 1000 cycles, lithium iron phosphate batteries have more than 2000 cycles, and lead-acid batteries usually have 300-350 cycles. Then it means that the life of lithium batteries is about 3-6 times that of lead-acid batteries.
Lead-acid batteries are currently cheaper than lithium batteries, which are about three times more expensive than lead-acid batteries. However, by lifetime analysis, lithium batteries have a longer lifetime if the same cost is used.
Environmental Protection
Lead-acid batteries are very polluting, while lithium batteries are relatively greener in terms of production and recycling.
How Long will A Fully Charged 48V Lithium-ion Battery Run My Home?
The range of a 48V Li-ion battery is related to the capacity of the battery itself (Ah) and the total power of the household appliances (W). Assuming you are using a 48V 200Ah solar home battery and the total power of the household appliances is 1800W, then the running time of your home is 48V200Ah/1.8kW=5.3h.
How Many Hours Does It Take To Charge an 48V Lithium Battery to Full?
charging time and voltage does not have much to do with.
Mainly depends on the capacity of the lithium-ion battery and the power of the charger, charging time = lithium battery capacity ÷ charging current
For example, 48V 5kWh lithium-ion battery, assuming that the maximum charge current allowed is 50Ah, then the theoretical charging time of 4 hours, that is, 200Ah ÷ 50A = 4h, but the actual charging constant current to constant voltage mode, the trickle charge at the end takes longer, so under normal circumstances are in about 5 hours. Similarly, if the allowed charging current is 20Ah, it takes 200Ah ÷ 20A = 10h, but the same trickle time, so it is about 12 hours or so.
V Lithium-ion Battery Can Not Be Charged into How To Do?
Whether the solar panel output parameters are normal, voltage, current, etc.
hether the charger line is normal, whether the connector is disconnected
whether the 48V lithium battery is bad, you can test whether the open circuit voltage of the battery is normal.
Consult the lithium battery manufacturer.
V 13 String and 14 String Difference
NCA only divided into 13 or 14 strings, lithium iron phosphate is 16 strings
But the NCA 13 string discharge platform is significantly lower than 48V, the speed is slow, 14 string good
13 string full voltage 13 4.2 = 54.6V, rated voltage 13 3.7 = 48.1V, as of voltage 13 3.2 = 41.6V
14 string full voltage 144.2=58.8V, rated voltage 143.7=51.8V, as of voltage 143.2 = 44.8V
13 series can be better compatible with lead-acid battery electric car, lead-acid battery electric car normal is 124= 48V, as of voltage 10.54 = 42V
LiFePO4 / LFP is commonly referred to as iron phosphate, the nominal voltage of each cell is 3.2V. This means that to make a 48V battery pack requires 16 LiFePO4 cells, 16 strings full voltage 163.2 = 51.2V, LiFePO4 is considered to be the most fireproof, and their LiFePO4 is considered to be the most fire resistant, and they typically last twice as long as ordinary NCA/NCM 18650 battery packs.
