13.4KWH UPS Battery Pack , 48V Lifepo4 Battery With BMS / Metal Case
13.4KWH UPS Battery Replacement LiFePO4 48V 280Ah Battery With BMS And Metal Case
Our 48V 280AH Lithium Polymer Battery (Li-NCM) can be used to UPS repacement, Electric vehicles and other energy storage applications. The Lithium Polymer Li(NiCoMn)O2 Battery is a type of rechargeable battery based on the original lithium ion chemistry, created by manganese(Mn), nickel(Ni), cobalt(Co), as cathode material. Li-NCM cells have a flexible, foil-type case, therefore they are relatively unconstrained. Due to electrolyte decreasing, further enhancing battery safety and being able to be positioned in any direction.Our Li polymer batteries passed all safety tests(short circuit, overcharge, overdischarge, over temperature, needle penetration tests, vibration, thermal shock, free drop, crush etc). These battery cells are no explosion, no fire and no leakage.

Charge and Discharge Curve
Quality Assurance
We do nail penetration test with fully charged, no fire, no explosion, completely safe.
Aditionally, high rate discharge( 40C), self discharge rate, short circuit, thermal shock, hight temperature performance
, crush test and free drop test are carried out and passed accordingly.
