i dont know if any one else has seen this but zippy came out with some new flightmax lipos. i know they have had the flightmax lipos out for a while but they came out with new sizes

they now have 2 , 3, 4, 5, 6cells 5000mah in 20c, 25c, and 30c.

and they are shorter too. only 140mm instead of 150mm or 155mm
