I would be more concerned about lipo failures than having a setup that runs 20 degrees cooler than what is already acceptable. The more cells there are in a pack, the more vunerable the cells are to undervoltage, since a weak cell has to go way below the safe limit before the mean voltage of the cells in the pack triggers the cutoff.

Ok, I will say that for most situations that 6s would be fine in a mt geared for around 40mph. Given a sytem properly setup for 6s and another that has a motor with half the kv on 12s, the 12s setup will pull half the amps that the 6s does, and produce more torque. Plus the batteries can be half the capacity and provide the same runtime (most likely more). I am sure that a expernisve motor in a hv setup will run cooler, but not so cool as to fail. Most find a feigao xl to be ineffiecent, and heat up to much, such as a 7xl on 4s. I run a 14xl on 8s lipo and it performs fine, in a heavy savage, and I use a 60amp air esc that barely gets warm. Plus I can get away with 12c lipos, my 3600 polyrc lipos only cost 120 bucks (30 each for 2s 3600 12c packs x 4). I would love to see another 120 dollar lipo compare to this setup in either 4 or 6s. The lower loads placed on the cells by a hv setup will help the cells stay in balance. High current draw is what causes cells to come out of balance. Hv just makes sense for larger,heavier vehicles. More torque, less load on the battereis, and cooler running with cheaper equipment. For me hv is the only way to get a feigao to work properly, but then they are great value!
