Stim Battery Hot

I am using my stim for the first time testing my MIIv3 power supply. The battery gets very hot within about 30 seconds and hotter even faster when plugged into the MS. Is this normal? Also, am I better off using the plug in power supply for the stim? All of the MS documentation refers to battery usage.

The Stim draws a fair amount of current and can burn out 9V batteries in a hurry, so a power supply definitely helps. I'd first make sure you don't have anything shorted out in the board, but the battery can sometimes get hot even when it's working OK.
