I’m using an Adafruit micro-USB Charger connected to a standard 850mAh LiPo battery. I would like to know if it’s safe to charge the battery while also using it. The circuit that the BATT and GND pins are connected to will draw about 60-150mA. The charge current is 500mA.
From what I can tell, the charger board does not implement the MCP73831’s load sharing feature. I believe this means any load will be paid out by the charge current. Is this okay? In testing, I can see so far that the DONE light never illuminates (battery gets to about 4.18V and as soon as I disconnect BATT from the remainder of the circuit, it illuminates).
