I would guess that amp draw would be around 85 amps. That is not an average, or max, but more of a battery guideline. I would say that a fp 3700 25c 6s pack would work fine and still be reasonably light. Motor kv is a bit much, will this be a 1515 or 1512? For a 1512 2200kv on 6s lipo in a buggy you may be able to step down to a smaller 6s pack.

I run a medusa 36/60/1500 in a hyper8 on 6s lipo. I use a pair of fp 2170 3s lipos in series for 6s. They work fine, and I use 14/46 gearing on that buggy. Plenty of speeds and power, and decent runtimes too.
