Thanks for the feedback folks. Ok. I checked the voltage on my 3s 1000mah 10c battery and the voltage reads 11.42 fully charged. I'm using the stock Esky charger EK2-0851 that came with the King 2. The other battery is a 1250mah 3s 12c and it is reading 11.46 fully charged. I'm charging it with a cheapie charger, a Mini-smart 2-3 cell lipo charger balancer. Do these voltages seem ok? I think now that maybe the Mini -smart charger is only good for 1000 mah lipo cause the model number say LPC-1000 so maybe I'm not getting a full charge on the 1250 ? Also I found out I didn't have my esc programmed right for 100% power at max throttle.
