Neil thanks for the update on the latest zippies. i have been a MA guy but today was the last straw. sons and i were running the emaxx and erevo - both have MMM/s and 8XLs. towards the end of the run BOTH of the 8000 25C HV's puffed AND one of the 8000HV's in the erevo got hot, melted the battery container and puffed. 3 batteries in 20mins. sadly the one 8000HV which has the 3 year warrantyl didnt puff!!!
I am ordering a pair of the zippies now to see if they can at least last through a race without puffing.

Zippies perform pretty much to their advertised specs- voltage will drop under load, but with 6s lipo and a 2200kv motor you will naturally need to gear lower than normal (when running 4s lipo with a 2200kv motor for example), so the reduction in work load for the motor (lower gearing = more torque and less current draw) will help the batts somewhat. There are also 25-35c zippies that will work, and the newer versions of the zippies with a blue label on the blue heatshrink (especially for planes I believe), check the dimenions and specs as they might be better. You wouldnt be dissappointed either way for the price, or there are Mikes new lipos in the store that are performing very well (unbranded ones).
