Why are my batteries getting hot?

[wevie]

After checking things out thoroughly today:

1.) He is due for new wheel bearings. They are not smooth, but they are not shot, either.

2.) Unable to locate any physical drags, I plugged the MM into the 'puter and it came up with a setup error. It said Punch Control Out of Range. ??!!?? I don't understand how that could be. I'm the ONLY one that has the ability to plug the MM in and change settings and I doubt if it would be possible to get the Punch Control out of range by just fooling around with the ESC.

Anyway, after resetting the parameters, he ran two Tenergy packs today without any heat issues.

Thanks for the help!!

Interesting. So the punch control being all out of whack was the culprit then? I don't think you can set the punch control to more than 100% to begin with anyway. Definitely odd!

I wonder if you have a defective unit (in that it has the ability to apparently reset certain parameters way out of normal range...).

Anyways, like some others said, I would also keep an eye on those NiMH packs. I've had IB4200s (notorious for having a short life span but great performance) poop out rather suddenly (not as gradual of a performance degradation as you may think, or that I thought I'd experience).
