The lithium iron phosphate (LiFePO
4) battery, also called LFP battery (with "LFP" standing for "lithium iron phosphate battery"),is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO
4 as a cathode material, and a graphitic carbon electrode with a metallic current collector grid as the anode.
The above is standard description for LiFePO4 battery.But here we are going to intrduce a specific LiFePO4 battery cell-38120 type(Headway 38120).It is a round shape cell.
38 means diameter 38mm,120 means height 120mm(exclude terminals).Covers by blue color wrap.
Discharge depends on the screws of cathode and anode.
