The battery needs to be able to be easily charged without the user having to remove the battery from the device.
I included some diagrams that I made quick in paint. I’m trying to have the Li-Ion battery power both the micro-controller and servos. I was thinking that when the switch was OFF (not connected), the charger can be plugged into the circuit (DC connectors) without removing the battery.
I’m using a 7.4V Lithium Ion battery and a Li-Ion smart charger:
Would the charger harm the micro-controller if the switch was ON? What do you think, will this work?
