3.7V 25Ah Lion ion Battery Cell for Golf Cart / RVs , High Density and Safety
Our 3.7V 25AH Lithium Polymer Battery Cells (Li-NCM) can be used to 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.
