I figure quite a few people are using these packs, we should collect our experiences in here.
I have about ten of the 5ah 6s Zippy flightmax packs in both 15c and 20c discharge rates, and have 6 of the new Turnigy 5ah 6s packs on the way. After about four months of riding on them I must say they are a great value. The soldering jobs are not always the best, but for the cash it is hard to beat. The one drawback is when they get close to full discharge, around 85% DoD, the cells start to really get out of whack. I rode last night and was just hitting the end of the pack when I got home (typically I will have at least 20% pack left). When I let them rest and plugged them in the two 6s packs I was using were a full volt off of each other. Typically they are dead on even. Voltage difference was at most .2v per cell on each pack, quite a bit larger than I like to see. Because of this I will run my LVC at 3.1 or 3.2v per cell to prevent capacity loss.
Moral to the ride yesterday, I will be running 12s2p on any ride that will be using more than 3.5ah (70% dod).
Anybody else noticed the same occurrence?
