24V Solar street light battery solution
GeePower® 24V 50AH Solar street light battery is assembled by 8pcs 3.2V 50AH GPLFP10192320 LiFePO4 battery cells in series.
GeePower®3.2V 50AH LiFePO4 polymer cheap lithium batteries can be used to Electric vehicles and other energy storage areas. These Lithium Iron Phosphate (LiFePO4) batteries, produced by GeePower here in China, are rated at more than 2000 recharge cycles, can be assembled in series and parallels with a battery management system (BMS).
The Lithium Iron Phosphate Battery is a type of rechargeable battery based on the original lithium ion chemistry, created by the use of Iron (Fe) as a cathode material.
Already passed all of the safety tests(overcharge, overdischarge, over temperature, short circuit, drop, Crush, Needle puncture tests, etc). These battery cells do not catch fire, no explosion and no leakage.
