MM on 6s? check these batts out

[Revracer]

actually i didnt play into affect that im running a motor with 3500kv... i just saw 3s 4500 lipos for $50... that was like... whoa! but yeh 6s would be pushing near 80k rpms, nearly double the recomended for the motor... haha. still looking at the swang 2s packs though. they seem like an amazing deal... unless someone else knows where i can get batts that sized for that cheap?
