High current peak discharge of 40AH LFP cells

High current peak discharge of 40AH LFP cells

The graphs show the discharge of 40AH LFP cells with 100 Amp and 500 Amp currents. These high current tests prove that the performance of the cells is very identical and that there is no defect of these cells.

Depth of discharge (DOD)

Depth of discharge (DOD)

All battery manufacturers recommend to keep the Depth of Discharge (DOD) bellow the maximal limit of 100%. Ideally 80% DOD or less is recommended. The rule is quite simple: the smaller DOD the larger number of cycles. With 50% DOD the LiFePO4 cells may have well above 5
