Latest news, guides, and articles about battery storage. We write about lithium-ion, LiFePO4, and more.
The principal benefit of lithium ion batteries is their ability to store large amounts of energy in a relatively small space. Lithium ion batteries have the added benefit of having an extremely high depth of discharge compared to lead acid batteries. This is why lithium ion batteries are generally the only type of battery to use for energy storage.
For energy storage applications, nominal voltages of 12, 24, and 48 are used. This generally means that the batteries in the energy storage system will generally be in either a 3S (4S for LFP), 7S, or 13S series configuration. Energy storage batteries generally have an amp hour rating of 100 Ah or more, but smaller energy storage batteries can be made.
Articles in this category will revolve around long term energy storage, electrical preparation techniques, high capacity battery packs, and various series and parallel battery configurations.

After building your battery pack the next step is to figure out what type of connector you need to attach the pack to your load. Making sure you pick the right size and type is crucial to avoid any safety or heat issues. Undersized connectors and wires are some of the most common reasons for pack failures.
Making sure you are storing batteries of varying chemistries at their optimal storage voltage is a good way to increase longevity and safety. Storing batteries and cells at proper storage voltage mitigates some degradation a cell can experience while being stored.
Nowadays the only reason to use lead acid/agm comes down to upfront costs. Long-term lithium is the best all-around performer for your energy storage needs. we detailed all the pros and cons of lithium vs AGM so you can see for yourself.
Recovering low voltage and 0 voltage cells and batteries can be anything from a quick and easy process to something more challenging. Learning what to do in these situations can be critical when learning to salvage batteries. This guide should help you learn the process to get the job done!
Keeping batteries at their proper temperature range is crucial for maximum performance and longevity. There are several ways to accomplish temperature control of your pack, which we lay out in this article.
When building a battery pack being aware of the individual cells' internal resistance can help you build a more optimized battery pack. Being able to test the IR of salvaged cells is even more important as it helps you to understand the health of the cells. We put together this guide to help you test the IR of cells.
Learning how both active and passive balancing works is important knowledge to gain before you build your first pack. This can also help you when it comes to fixing battery packs that are no longer working. We put this guide together to help teach you about the two and how and when to use either or both.
If you are building a battery pack and you don't have the means to get a spot welder. Soldering cells together to form a pack can be a viable option although it is not preferred. Soldering cells comes with its own challenges and risks.
When building a battery pack or combining two batteries it's good to know the difference between series and parallel connections. This helps to determine which connection type is best for your project. We've broken down the basics to help make this decision easier.
