W-STANDARD Lithium Iron Phosphate (LiFePO4 or LFP) e-battery engineered from laminated aluminium film and lithium-ion combination. It produces high output energy, low internal resistance and safer to use. The LFP e-battery does not contain lithium cobalt oxide (LiCoO2) or lithium manganese oxide (LiMn2O4), making them safer from fire or explosion.
W-STANDARD lithium e-battery is strictly tested accordingly to international standards, by the Pony Test Centre UN 38.3. Among the top key aspect tested are performance, capacity, discharge rate, puncture, extrusion, vibration, short circuit, over-charge & over-discharge and etc.
W-STANDARD lithium e-battery is eco-friendly as they do not use heavy or rare metals.
