I got the starter kit using the RAK 4630. I cannot get the board to power up using the battery port. The USB and Solar ports work just fine.
With the USB port in use I can voltages on cables connected to the Solar and Battery ports (4. 76 volts - Solar - and 4.21 volts - Battery).
The batteries are charged fully. In my testing I used my bench power supply and slowly ran the voltage up to 5 volts, while connected to the battery port. No joy.
Am I missing a configuration? Ideas?
