Do you have a technical question that doesn't really fit a specific console? Want some general info on electronics, hacking, making cookies, etc? Here's the place to ask! Go nuts.

it would seem to me that you want to wire your portable up to v+ and ground but ideally you should use a multimeter to find out which is giving off the 7.4v. as far as charging it, hopefully someone else can help :/

That charging circuit looks big and overly complicated.

You could just take out the batteries and buy a cheap protection circuit from batteryspace and connect the batteries to it.

I think Ive seen this battery, It has a built-in DC-DC converter. I think. It outputs 9v right?

Id recommenced using the external charging pins or getting another protection circuit.

I think you'd want to wire up the charger and load to P+. At least that's what you hook up to with these circuit boards. I would assume the P stands for protected, but that's just my novice deductive logic.
