What about lipo's...i been using 4s when i bash. when i went to the track my friend told me 2s is perfect and 4s ill be way overpowered. so i went with 2s. 2s on my mmm 2200 kv 44/25 gear setup. Tonight ill be going to a track that is bigger and my friend says that i can use 4s with my setup. In all honesty, on a track I am comfortable with just using 2s now. i just want to make sure that it is not in any way damaging or wearing my motor down more than it normally would.
