Charging algorithm

This is the "European" charge algorithm that does not float charge the battery at the last stage, but still keeps it maintained. (see the graph below)Constant current/constant voltage

Stage 1 slow start, precharge function for deeply discharged packs

Stage 2 bulk charge stage. 3.3 amps is applied to the battery until the voltage rises to 12.6 volts

Stage 4 constant voltage state until the charge current falls to 400mA

Stage 5. The charger turns off.
