<p><b>New page</b></p><div>Hi,<br />
<br />
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?<br />
If I understand it correctly, then the UPS tries to charge its battery from its own output. Is this really the case?<!-- migrated from Comments; original IP: 62.157.37.152 --></div>62.157.37.152
