resqguy- (volts, mAh, cells?) I'm a newbie myself, but I've done some research, mainly here, and the other rc sites, businesses online, and asking questions of ebay dealers - great sources of info. Still don't know much about charging batts, but can tell you li-pos come in (usually) 2 (7.4V) or 3 (11.1V) cells. mAh is basically an indicator of TIME - the more mAh, the longer you can fly; depending on a bunch of variables, a 2000 mAh will fly a lot longer than a 740 mAh. Trade-off, (as always in electrics there's a trade-off) is weight & cost. The more mAh, the heavier & more expensive the battery. I may be wrong but so far as I can tell, one brand is pretty much the same as any other - sorta like alkaline batteries - according to Consumer Reports, the only variable with alkies is price. I would look for a connector that matches, or buy some and fab up yr own and an adaptor for yr charger. DO NOT CHARGE A LI-PO WITH A MIMH OR NICAD ONLY CHARGER. Bad for the health of yr car, house, lifestyle, and lots else! Bil
