Default battery pack really hot after running

In my custom micro monster truck the battery pack gets hot after I run it. I'm using a 1000mah micro battery pack and a epic binary 2 10 turn motor. The motor doesn't get hot at all but the battery pack get really hot. Hot enough that it melts the heat shrink wrap a bit every time. I just cut a hole in the rear window of the truck body to let some heat out. What else should I do to keep it from getting do hot.

You're running WAY too hot of a motor for those cells. They're not made to run anything near that. You need to either put regular, sub c cells in the car or go to a motor more fitted to the size of the cells. You can go with a speed 300 or something like that. But a 10 turn will cook those cells. I'm sure a stock motor would probably cook those cells.

I need the power of the big motor so I guess I'll change the batteries. Would GP AA's be good, Since They're small? Would they be able to handle the power of the motor?

Thanks

No. For that motor, you need to get some regular Sub-C cells. What are you using for an ESC?

you need some GP3300's

those cells you are using are rated around 15A or so, and your 10t can draw around 30A+, and it will be even worst if you use AA or AAA

If you're not racing this thing competitively, just go to a hobby shop and pick up some loose cells. They can be anything really. Sanyo 2400's, 3000's, or GP3300's. You can get unmatched cells very cheap. Especially 2400's.

I'm amazed that the shrink wrap of the battery didn't just melt.

It started to melt in a couple little spots.

The only problem I have is that sub c cells are to big to fit.
They might fit if I arrange them in a weird order.

I don't have my digital camera or the memery card so I can't put the pictures on the computer right now. I'll have it back in a few days.

I'll find some that I put on other site.
