Angry E-maxx 7 cell problem

I got an E-maxx for Christmas and just purchased two 7-cell battery packs to run in it. The problem is that when I plugged it in, there is no juice. To answer several obvious questions first ... I charged the batteries using a peak charger the night before (and they took the expected amount of time to charge), secondly there was a little life, in that the ESC would show green lights when the trigger was pulled full throttle, and blink green lights when full throttle in reverse. In addition, the steering worked and would respond, as did the shifting from 1st to 2nd gear, just no power to run the wheels.

I had just run the car on two 6-cell sticks, where it ran just fine to completion. Is there any "programming" that needs to be done to the ESC to take the 16.8 volts? Could the batteries themselves be bad? Any thoughts would be greatly appreciated. Thanks!

an emaxx speed control can only take 14.4 volts. your 7 cells are useless in the truck. the speedo limits at 14.4 input volts. your trying to put too much power through it.
89% of Revos are racers. If your Revo can out-bash and out-run a Savage, put this in your sig.


46.7% of all statistics are made up on the spot and have no real value or truth.

no programming needed, it's probably a dud ESC or an obvious problem we havent seen.

if you have a chance, get a real esc from an e-savage.
