Your asking questions i was asking like 2-3 months ago! USUALLY camcorder batteries come with protection circuit(weird how yours doesn't). Any way you need them for li-ions and li-poly batteries, head over to...ugh forgot the name, was it battery space that you guys always use for batteries and circuits? I think it is so go there(www.batteryspace.com) and buy a circuit for 2 batteries.
As far charging simply connect the positive of the charger to the positive of battery and neg of charger to neg of battery. But eventually you'll need a switch for the power to go through and be able to cut off power(turning off the console). For this go here http://forums.benheck.com/viewtopic.php?f=43&t=31195
