I've got a new 510 with a PCC, and the kit I ordered didn't come with a battery charger. Presumably, you charge the PCC and with that, charge the battery. I'm wondering if I can do them both at the same time, i.e. screw the battery in the PCC, then plug the PCC in. Would both the PCC and the battery charge at the same time, or would I have to do this in two steps?
