Electronic problem.

I know I know Serch.
But I dont know how to serch this.
I have a teken fxr, 55t novak add two 1800 nicd battiers.
For a while I had the battiers set up in parralel for longer run times, It didnt really seem to help eny. Then just to try it I decided to run them in Series. WOW, what Power it has. But it will start to kick off and pause and not move until I turn the front wheels by hand. Every thing goes back to normal when I go back to running one battry or in parrillel.

What Is happining.

Parallel gives you 3600 mha, or double the run time. Series gives you 14.4v, which is a lot higher than that speedo is rated for. I'm guessing it is shutting down on temp, unless it has a built-in voltage limiter.

I'd save the weight and just run one pack, you still should have good run times. If you want more power I'd recommend going 3S lipo or 7/8 cell nimh

This is what I was thinking but was wanting confermation from some more experienced electronics people.
The reason I wasnt sure is that the ESC has all the settings for the diffrent batteries and the NICD didnt say eny thing about limits.
Thanks for the response Ill quit trying to push it now.

A ESC voltage limit is just that, a limit. The ESC dosen't care, or even know, what battery chemistry is providing the volts.

I'm willing to bet there is a listed "acceptable voltage input range" for the ESC. Maybe something like, "4-7 cell NiMH/NiCD, 2S-3S LiPo".
