The following things need to be changed:
The following things need to be changed:
- Footprint of the DC connector
- Holes for the big overdimensioned diode are too small
- Concept for 5V systems
- At the moment the voltage is stepped down from the 2s connection but batteries do not charge when the charger is supplied with 5 volts.
- The new idea is to change the batteries to parallel Connection - so we would only another protection device in this case and a switch for the connection change but the rest could stay the same
- At the moment the voltage is stepped down from the 2s connection but batteries do not charge when the charger is supplied with 5 volts.
