BigBattery off-grid lithium battery banks are made from LiFePO4 cells, which are the best energy source because they store more energy than any other lithium or lead-acid battery. Our solar batteries are the lowest-priced energy source in the long run and are cheaper than lead-acid batteries. Lithium-ion batteries can also store almost 50 percent more energy than lead-acid batteries!

Additionally, they work between 5,000 and 8,000 cycles vs. the old 500 cycles that a lead-acid battery would provide you. BigBattery off-grid solar batteries, made in the US, are the safest and most secure option for any solar application. With built-in BMS and numerous safety features, you can rest easy and let our solar battery do the work for you. We have 24V and 48V lithium solar batteries to fit you with the right system for your solar application!
