Before you set /calculate SOC , please enter password: AF123456;

How to get correct SOC now?

Set the design capacity / full capacitu / residual capacity in the pc software as below ;

regarding the residual capacity , please enter 1/2 full capacity

and then take a complet cycle of discharging and charging ; finally the SOC will be calibrated automatically

Let me take 96S and 128S for example , please see following :

 

If lifepo4 battery 128 cells in series , please do setting in the following way :


Step 1: Select  "128S +8 bmu(16s)" and then press the button "Load”
