I've been pondering about this one for a while. I am interested in having my gp2x running off this battery pack, http://www.batteryspace.com/customizepolymerli-ionbattery37v3200mah118whwithpcb.aspx . My question is, how can connect this and make it easily removable for the purpose of recharging. What kind of connector should I get? I would like to hook up a connector to the gp2x battery terminal and another to the battery pack so it can be plugged in and taken out for charging and buy a charger that uses that type of connector. Thanks in advance.
