DOD (Depth of Discharge) is a metric that measures the percentage of the rated capacity a lithium battery has discharged from full charge to its current state. Simply put, if a battery is used from full charge to 20% capacity, its DOD is 80%.

Lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate (LiFePO₄) as the cathode material and carbon (graphite) as the anode material.

The rated voltage of a single cell is 3.2V, and the charging cutoff voltage is 3.6V-3.65V. Due to its performance being particularly suitable for power applications, it is also commonly referred to as lithium iron phosphate power battery or iron lithium battery.
