Well, to get 15 minutes of runtime on 18 cells... you'd only be running the motor at 13.5Amps or lower.... That's around 300 Watts.... It is possible... Know what I mean... 300 Watts is probably enough for just to have fun with.. but if you're pumping out 100Amps(2100 Wats) to the motor consistantly, it's only goin' to last like 2 minutes.... But the motor doesn't usually use up that kind of amps continuously.... Unless, you're always giving it a heavey load like on an incline, in bushes, or constantly accellerating hard... :) This is what I think.. I don't know how true it is.. .:)
