FAQs

A: Our battery can be used well below 0°C (can be normally discharged), but we don’t suggest charging the battery below 0°C.

It is like most kinds of the battery in the market now:Operating Temperature: Charge: 0°C to 50°C; Discharge:.20°C to 60°C.

Currently our battery can be charged at low temperature, but it is charged with a very small charging current. And we’ve used auto motive grade battery cells which have superior quality. Even if charging in low temperature environment for emergency usage, it will not damage the battery.

We’re planning to sell batteries with self-heating functions which allows it to be charged in freezing temps in a few months, and you could keep an eye on our store if you’re interested.

A: LANPWR Batteries are IP65 waterproof and dustproof design, but remember that water and electricity are a bad combination. Prolonged exposure to a high-moisture environment may cause water to penetrate the battery and cause irreversible damage. Like with most electronics, never submerge a LANPWR battery.

A: As long as it is a dedicated LiFePO4 battery charger, and the DC charging voltage can reach 28.4V~29.2V, and charging current less than 100A, it could be used to charge our 24V 150Ah battery.

A: There is no doubt that LiFePO4 batteries are one of the safest lithium-ion batteries out there. Due to its chemical properties and safe internal structure, does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries, will not explode or catch fire. In addition, each LANPWR Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don’t submerse the battery). For best performance reliability we recommend using a LiFePO4 charger.

A: A battery management system (BMS) is a device that manages a rechargeable battery (battery or battery pack). It can monitor the state of the battery to obtain calculation data to protect the battery. For example, it can prevent the battery from overcharging/overdischarging/overcurrent, and it can also provide battery balancing to a certain extent. The BMS can monitor the battery status represented by various items.

Voltage: The total voltage, or the voltage of a single cell.

Temperature: The average temperature, or the temperature of a single cell.

State of Charge (SOC) or Depth of Discharge (DOD): Indicates the charge level of the battery.

State of Health (SOH), various defined measures of the overall condition of the battery.

Current: The current flowing into or out of the battery BatteryFinds has its own factory to design and manufacture high quality BMS for all types of Lithium battery packs. We test each BMS before shipping and promise that the BMS is fully functional and secure.

A: Our 24V 150Ah battery supports up to 2 identical batteries for up to 48V (51.2V) in series connection.

A: We recommend that if you use 224V 100Ah batteries in series, you will get a 48V 100Ah battery system. And this way you will have more options and you could also assemble as other systems as you want. Another point is that the 412V 100Ah price will be more cost-effective.instead of 148Ah 100Ah.

Things to think about when building a DIY LiFePO4 battery!

If you’ve started planning costing out your van conversion, you can understand the increase in DIY offgrid power implementations because not everyone has the extra cash to pay a professional to install your van electrical system, plus you might actually want to build everything yourself!

One of the biggest expenses in an offgrid power solution is the battery itself, particularly for Lithium (or LifePO4 as the most popular lithium battery). It’s not uncommon to see of around £1000 or 1000 per 100ah for a basic LiFePO4 battery. Introduce automatic heating mats and the price goes up further.

We often hear the argument that “it’s crazy to consider LiFePO4 when Lead Acid is so much cheaper”, but actually if you were to match LiFePO4 performance with Lead Acid, you’d be surprised as to how many Lead Acid batteries you need to purchase to match the performance of a single LiFePO4 battery. Add in all the extra weight of having 3 Lead Acid batteries in your van and you can see why LiFePO4 is so attractive!

So what are the main reasons why people are reluctant to build DIY LifePO4 batteries for their van conversions?

  • Fear of the unknown
  • Lack of knowledge
  • Concern that it’s not as good an off-the-shelf battery
  • Scare stories of bad components
  • Safety concerns

In this article, we attempt to tease this out a bit hopefully give you some advice on some of the things you need to think about.

Do you really need to know what you’re doing?

When you think of it, ten years ago it was so easy messing around with Lead Acid and AGM. So has technology advancement made it more complex for you?

If you want to build your own LifePO4 battery you do need to know what you’re doing. You don’t need to be an expert, but there are some basics that you need to know.

Do you need to know about the chemistry? We see so many Youtubes where the person says “I’ve studied the chemistry” and you feel a bit lost.

In a nutshell: Not really. There are a few basics you need to know and that’s pretty much it.

Fear of the Unknown

This goes hand-in-hand with the lack of knowledge which is discussed next.

The thing is that you don’t know what you don’t know. For this reason, you would need to set aside a few hours to bring yourself to a level of knowledge that the fear of the unknown becomes manageable.

Lack of Knowledge

Building a DIY battery is something that has tons of information on the web, from YouTube to the plethora of blogs white papers. Not to mention the forums groups.

The point is, there is a TON of help and advice out there.

So how do you go about acquiring the knowledge?

Our suggestion is to start with your friends Google, YouTube, Blogs, Forums groups.

What do you need to be on the lookout for?

These are the major topics you’d need to study:

  • What goes into building a DIY LiFePO4 battery? That is to say, what components will you need to purchase?
  • Top balancing brand new LifePO4 prismatic cells.
  • Physical construction (assembly) of the battery and BMS, securing and compressing the cells.
  • Attaching and testing the BMS.
  • Finally. what tools will be needed?

And all your investigation you’ll be keeping safety as your top priority.

Concern that it’s not as good an off-the-shelf battery

We think, actually we know, that there is no reason why your DIY battery should not be every bit as good as an off-the-shelf item, if not better! We’re assuming you’re not going to skimp on quality parts. Your battery may look a little DIY but that doesn’t matter. What matters is how well it’s put together, what components were purchased and how you’ll be looking after the battery going forward most importantly, does the battery give you what you need in your van? E.g. can you run your coffee machine, induction stove, TV, projector, PlayStation 4, etc.

Scare stories of bad components

This is a valid concern. If you’re building a single 280ah battery you’ll be planning to make a single purchase of four cells from a plethora of sellers, either local or Alibaba. How on earth do you tell one supplier from another? They all have beautiful pictures of pristine factories, people standing at testing equipment etc. Our recommendation for finding good sources for cells is to spend time reading reviews on forums to shortlist some manufacturers that are tried and tested, which will be a safer bet in terms of the quality of the cells and stick to their more well-known manufacturers unless you’re comfortable with taking a gamble on cells that are not as well known.

Safety Concerns

This is quite valid. And it covers a plethora of possibilities. However, anyone can learn how to safely work with 12v or 24v LiFePO4 batteries and effectively safely build a battery system. Like with a lot in life, the unknowns are often the things that scare us the most, but with some good research, you can be clued up in electrical safety so that this is not an issue.

Remember that you are automatically working with Direct Current (DC), which by default is already safer than Alternating Current (AC).

Let us say: while we think you should be safety conscious it’s perfectly manageable.

What are the main safety concerns to bear in mind?

  • The battery could explode and/or catch fire
  • Construction hazards such as a tiny bit of molten metal flying into your eyes
  • Fires starting from shorts (this could happen with any battery chemistry though)
  • Leakage of the “lethal stuff” in the battery cells

How do you overcome these valid concerns?

Educate yourself. once again Google, YouTube, Blogs and Forums are your friends.

Here are some of the things that you might need to know research:

  • You need to know what PPE to wear when assembling and working with the battery components.
  • How to prevent shorts.
  • What tools to use. Try and buy insulated tools that are intended for electrical use, especially if you are not experienced or confident.
  • How to inspect LiFePO4 battery cells for damage and/or leaking fluid.
  • What to do in the scenario that your battery cell is leaking fluid.
  • How to prevent electrical fires.
  • How to extinguish an electrical fire safely efficiently, and what safety equipment you should have on hand to extinguish an electrical fire.

To summarise, there might be a bit of learning you need to do, but it’s totally achievable. There are a bunch of great resources online, which could help. We have our blog YouTube channel that we post regular content on. Will Prowes is another YouTube channel with a wealth of information.

The Dangers of Building Your Own DIY Lithium Battery Pack

With so much information on the web, more people are trying to build their own DIY lithium batteries. After all, lithium batteries can be expensive, and it can be cheaper to build your own. But regardless of why people do it, it can be extremely dangerous to build your own batteries.

In this article, we explore what a lithium battery is, whether it’s possible to make your own, and why it’s not worth the risk.

What Is a Lithium Battery?

A lithium-ion battery is an advanced type of electrochemistry that uses lithium-ions to deliver power to our handheld devices, vehicles, RVs, and everything in between. They’re comprised of an anode, a cathode, and a battery electrolyte solution that carries the ions from the anode to the cathode (when discharging) and from the cathode to the anode (when charging).

Lithium batteries have transformed our world because they have a high energy density, and therefore, they allow us to pack a lot of power into small compartments. Furthermore, they can emit more power overall because they aren’t as affected by the Peukert effect as lead-acid batteries.

Can You Make Your Own Lithium-Ion Battery?

For most of us, lithium batteries work well at powering our devices, gadgets, and vehicles, and we don’t think much about them. But there are some circumstances that might warrant the question: Can I build my own lithium battery pack?

For instance, building DIY lithium batteries can be popular among those who want to power a device, such as a bike, skateboard, or other motors. This is because lithium batteries are generally more expensive than their lead-acid replacements, and it can potentially be cheaper to build your own.

So, yes; it’s possible to build your own lithium battery pack. But should you? Probably not.

Let’s take a look at why building your own lithium battery isn’t such a good idea.

Why Is Building a DIY Lithium Battery a Bad Idea?

Let’s explore the reasons you should think twice before building your own lithium battery. As you read through, remember all of the safety features and testing that battery manufacturers conduct when they’re building batteries. Ask yourself: Could I produce the same results as a factory? The answer is probably no.

No Warranties or Guarentees for DIY Jobs

So what happens if your battery malfunctions and destroys your electronics beyond repair? The problem with building a DIY lithium battery is the lack of a warranty.

Most devices come with some protection against these occurrences, but not for self-built batteries. Therefore, your battery will be at an increased risk of failure, and whatever you’re powering may sustain critical damage.

No Testing/Quality Control

As mentioned before, high-quality battery manufacturers like Battle Born Batteries conduct rigorous testing to validate battery performance and ensure the safety of their products. However, if you make your own battery, you probably can’t replicate the tried and true battery-testing methods that the manufacturers use.

In addition, batteries like Battle Born hold outside certifications that require rigorous testing for safety. The lithium cells in Battle Born’s batteries are UL 1642 certified and the battery packs themselves are UL 2054 and IEC 62133 certified. Additionally, each battery has a Department of Transportation listing of 38.3, which is required even to allow them to be shipped.

Without testing, you might not know there’s something wrong with the battery until it’s too late. And you probably don’t have the equipment, knowledge, or manpower to conduct these tests yourself.

Unmatched Cells, Volts, Amp Packs

Another issue that can arise lies in the battery construction. Problems can easily occur if the battery cells don’t uniformly emit power, the motor doesn’t withdraw the correct amperage, or the bus bars can’t handle the amps running through them. These are all risks when constructing your own lithium battery pack.

Conversely, every single Battle Born Battery cell is tested under load before assembly. Then each finished battery undergoes a quality control test to ensure they meet our strict voltage and amp-hour standards.

BMS Reliability

If you’ve looked into how to build your own DIY lithium battery, you’ve probably heard of a Battery Monitor System (BMS). BMS’s are an essential part of a lithium-ion battery. They ensure that the battery works properly by monitoring the battery. Depending on the manufacturer, items like temperature, load, voltage, SOC, resistance, and current are measured. If something is not right the BMS disconnects the battery to keep it safe.

Therefore, if you don’t have a reliable BMS, you won’t know your battery is working as it should. Plus, you’re without safety features if it malfunctions.

Battle Born Batteries utilizes a proprietary BMS that is designed specifically for our packs, highly tested, and designed to last for the life of the battery.

Lithium Battery Fires Are Hard to Put Out

This last point is a worst-case scenario, but unfortunately, it’s a reality for lithium-ion batteries.

First and foremost, lithium batteries pose a fire risk if not properly built because of their high energy density. If one of the cells fails, which can happen if it’s not made properly, the resulting heat can trigger a chain reaction called thermal runaway.

Depending on how many cells are in the battery and how well they’re vented, this could cause a massive fire that might be difficult to get under control.

It’s not an uncommon story for homemade battery packs to operate fine for a while but spontaneously burst into flame in the future due to a construction flaw.

Thus, you may inadvertently create an explosive in your attempt to make a cheap DIY lithium battery.

→ After reading these, you might be asking yourself “Are Lithium Batteries Dangerous?” Most of the time, no. Read this article to more fully understand the factors at play, and why purchasing from a trusted source is so important.

Should You Risk Building Your Own Lithium Battery?

You know the saying: “I know just enough to be dangerous”?

Consider that this might apply to you building your own lithium battery. If you know the basics of constructing a battery and think that you can with the right research and materials–please reconsider. DIY lithium batteries can be extremely dangerous if made incorrectly, and many things can go wrong.

So if you ask us, just don’t do it. It’s not worth the risk. While you may say we’re biased, you’d be surprised how many stories our customer service and tech support teams hear about DIY attempts. Often, those same DIY builders end up swapping their home-builds out for reasons of unreliability, peace of mind, and sometimes the worst case where they experienced a fire.

Invest in a Quality Lithium-Ion Battery Instead

Lithium batteries are amazing! Their high energy density make it possible for us to store power in small, portable ways, and they’ve completely transformed our world because of it.

Nevertheless, they can be extremely dangerous if not built correctly. Various things can go wrong, including thermal runaway, and ultimately, a fire that’s difficult to put out. This is why we strongly advise against trying to make your own DIY lithium battery. Not only can it destroy your personal property, but it may also put your safety and others at risk, as well.
