ESS Battery System 12V 40Ah LiFePO4 Li-ion Battery Pack with BMS


Product Description 


1. Lithium iron phosphate battery is environmental friendly.The lithium iron phosphate battery has environmental benefits because it contains no heavy metals. Lifepo4 battery is strongly advocated by the government and has been applied to the field of electric bicycle and electric car.

2. Lithium iron phosphate battery has constant capacity. If the ordinary battery is in the case of long-term unfull charge, the battery storage capacity will be reduced quickly. And the characteristic of lithium phosphate battery is that it can be used or charged no matter how much SOC it has, and will never affect its storage capacity.

3. Lithium iron phosphate is with excellent safe performance. Strict safety tests shows that the lithium iron phosphate battery will not explode even in traffic accidents after strict safety tests.
