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.

Learning to spot weld has a shorter learning curve compared to soldering. However, soldering allows a more robust connection. Picking which is best for your build comes down to your specific needs. Read more to let us guide you in making the best choice.
If you are building battery packs and handling many lithium-ion cells, then you are probably looking for the Best cell testers and chargers for 18650/21700 batteries. It’s obvious that anyone working with batteries is going to need a charger, but it may not be so obvious that you need a tester.
Power banks are more popular than ever. This makes sense because portable electronics are more portable and more power-hungry than ever. So, if you want to keep your portable electronics running as long as you do, you are going to need to know how to build a power bank.
When a cell group is out of balance, it can cause energy to be wasted because it can cause the BMS to shut off sooner than it otherwise would have. Because of this, learning how to wire an active balancer is critical in getting the absolute most out of your battery pack. Even if you don’t plan on equipping your lithium-ion battery with an active balancer, the process is the same for installing BMS leads.
If you want to be able to build a powerful, compact, high-current battery, then you are going to need to know how to do a copper-nickel sandwich. Nickel is usually used as the main conductor for building lithium-ion batteries. Nickel, however, is much less conductive than copper.
Using salvaged batteries and cells is an excellent way to save money and the environment. Untold amounts of lithium-ion cells are thrown away each and every day. In many cases, the batteries and battery packs that are being thrown away are either perfectly fine or only have a small percentage of battery cells that are actually bad.
If you are wanting to work with lithium-ion batteries but you are light on cash, then you can always learn how to break down lithium-ion battery packs. If you know how to break down a lithium-ion battery pack, you can save yourself a lot of money on cells by buying bad battery packs and equipment that contains them for cheap.
Using new vs used lithium-ion batteries for a particular project can be a challenging choice. Using used lithium-ion batteries helps the environment and can save you a lot of money while using new lithium-ion batteries ensures consistency and good performance.
Lithium-ion batteries are awesome. They are low-cost and can store a lot of energy. Building a lithium-ion battery is fun and rewarding, and building a charger is no different. When you can build your own lithium-ion battery charger, experimenting with all kinds of cell configurations is a lot more practical. For some use cases, building a battery charger is often cheaper than buying one and can provide a lot more performance.
