5.1 SPS-Charger board
The SPS-Charger board consists of switch power supply (SPS) and charger. The SPS generates all the
powers needed by dierent circuits.
You can set the charge current to be 1A/2A/3A/4A on LCD by conguring jumpers JP01, JP02, JP03, JP04
and JP05 you can also set charge voltage based on the number of baeries per string
