I am curious about running 2 shorties in 1/8 ebuggy. or the 4s short pack. I need to make 10min runtime with a 2100kv motor.

will the 4600mah short pack make 10min?
have ppl found concerns with 4s packs loosing a cell due to impact?
does the weight of the shorty equal out lack of mah?

thanks in advance.
