I have a project that uses a 7.2V battery pack for power. Up to this point, every time I need to recharge the pack I remove the power plug from my Arduino and plug in the charger to it. Works well of course, but I need to wait until the pack is charged to continue to work.
That pack power is also connected as DC motor power.
My question is: if I install two plugs in parallel on the wire that comes from the battery pack, connect one to the Arduino and the other to the charger every time the pack needs to be charged, will this setup charge the batteries and at the same time keep power to the circuit at around 7.2 to 7.5V?
