The lithium iron phosphate battery (LiFePO4), also called LFP (lithium ferro-phosphate) battery,
is a type of rechargeable battery which uses LiFePO4 as a cathode material, specifically a lithium-ion battery
for high power applications such as EV car, power tool and RC hobby. LFP cell has 3.2V nominal working voltage
and shall be cut-off power at 3.65V per cell during charging. LFP battery has the lowest cost if considering its long cycle life.
1: 140Wh/Kg energy weight ratio, 340Wh/L volume ratio.
2: Up to 2,000 cycles 80% DOD.
3: Operating temperature range,Charge: 0℃ to +45℃ Discharge:-20℃ to +60℃.
4: Safe/stable chemistry with no explosion & fire.
5: 1/3 weight of lead acid and 64% of Ni-MH.
6: Environmentally friendly.
