don't waste time on the quark! get a mgm and a neu. the quark will burn on 5s and won't even work on 6s. personally i would use 4s or 5s flightpower lipos so that longevity isn't an issue. the higher voltage you run the more efficiently your system will run! i think 5s should be the limit though, plenty of runtime and plenty of power. i am having great results with a 1515 2.5d on flightpower 5s 25c packs, everything stays cool!
