There's a lot of good reading if you search.
At our track we have been testing 21.5 with 2000Mhz 2cell Lipo (7.2v) and the only problem I had is that I tried a rollout that I was using on 17.5 with Sub-C Cells. I won't do that again since I almost ruined the Lipo pack
The 21.5 with a Lipo seems to be about as fast as 17.5 with Sub-C Cells. I would like to see a hardened case Lipo 2 cell that would work in BMI 1/12 scale chassis. Or a pack that has the cells separated to work on a T-bar car. Just a thought.
