I found the rules on the PDF version. Here's the battery rule.
Batteries: Any Reedy Wolf-Pack or Peak Racing Racing Powermax round-case Lipo battery may be used.
My guess is at a local track or regional TCS race I don't think they will be that picky. But, if you go the nationals they probably will. I have used the Peak battery and it's held well for over a year in a box stock M05 class and you can find them at a reasonable price. I don't know about the Reedy battery.
