I got my Stampede 4x4 yesterday and a banana-to-Traxxas adapter cable.
I've used my charger to balance charge LiPo's before and it stops automatically.

This is the first time I'm using it for NiMH.

Can anyone tell me how to set it up so it doesn't overcharge?
And also how to top off a battery that was charged the night before?

I don't think I'm allowed to post the brand name but it's a popular charger.
I thought I set a limit of 3000mAH but it continued to charge beyond that so I stopped it manually.
