They are Epic 3000mah Sport Packs that I disassembled and re-assembled with battery bars into an "E-Maxx style" 7 cell config (which is 6 cell side by side with 1 cell sideways to clear the battery bars).
lol, I figured the guys here would know NOT to run them with brushless.
I figured it's for anyone who has a brushed setup for their younger child and/or a rock crawler.
It doesn't matter to me. I don't gain or lose anything either way. So they are either going to someone here or going in the trash (figuratively, I'll take them to the proper disposal center).
