[quote author=xta-droid link=topic=9.msg2520#msg2520 date=1274964000]For itanium,Battery pack is 10 x 6 x 0.5 cms.[/quote]This is a battery for R/C heli or car, and does not have a balance charger built in. So, if the EKEN balance charger is part of the battery pack, just replacing it with this would probably cause some heat, fire or go-boom. (I've had one go boom on a short circuit and it was something else. You can actually buy "charging bags" for these R/C batteries, made of kevlar I think, for the cautious among us.) If the EKEN has its balance charger on the system board, then it might work. So where is the balance charger, that is the question.
