Long Life Prismatic Lifepo4 Cells, 6.4V /7AH Rechargeable Lithium Battery Pack
ES-LFP Series Lithium-ion Battery is an ideal replacement for traditional
lead acid battery utilizing advanced LiFePO4 technology and integrated
BMS with the benefits of long cycle life, light in weight, safety and
excellent high and low temperature performance. ES-LFP Series Lithium-
ion Battery is widely used in energy storage, UPS, golf cart and other lead
acid battery replacement.
