Well, my battery is a3200mAh 3S 11.1V 15C Li-Po. Iknow more mAh means more weight and CG shift. As much power as the motor has Im sure it can handle that little bit of weight. As for the CG shift, Illhave to compensqate I know. What I dont want to do is buy the wrong battery and render the ESC and motor useless. The apprentice doesnt give much info on the motor specs. I did find the replacement parts page and this is what it says- BL15 Outrunner Motor, 840K. And the ESC is a 30A Brushless Pro SB Brushless ESC. With that in mind, can someone go the extra mile and help a noob with a lipo question and maybe show a few links on the rightbattery(s)?
