Can I recharge a shared battery?
January 19, 2011
I just started messing around with a little RC boat (yet another way to emulate and test things for the bigger boat project I am part of) and it is getting the Fio that had been the brain in my AGV before I upgraded it. Anyway, the boat is small enough that to limit size and weight, I am going with one of those scary ol' LiPo batteries. One nice feature of the Fio is that it has an on board LiPo charger that will charge a 7.4v. I would like to take advantage of that, as that means as long as I make sure the mini USB port on the Fio is accessible, I can fit the battery in a hard to get at spot. A concern I have is that the battery will also be wired to the motor and to a 5v VR though. The motor will be MOSFET switched, but I am not sure I can do that with the VR. The VR is just for the steering servo right now, so I could use a resistor series and/or diodes if that helps with the charging question, which is - can I charge the battery with it being shared?
