Hi,
Connecting two USB-cables to RPi and UPS means that the 5V input on the UPS is directly connected to the 5V-pins of the RPi (Pin 2 and 4, see schematic of RPi). What happens when no external power is available and the system switches to battery power? If I understand it correctly, then the UPS tries to charge its battery from its own output. Is this really the case?
