I had a look at the Zippys, but, at the risk of sounding like a snob, I like Lipos with a strong brand behind them.
No offense taken,I'd just thought I mention them ?
I thought zippys were a joke also until I seen friends have fantastic success with them and read where many people were also content. I've bought 8 different packs and couldn't be happier. I hope you find what your looking for.
I retired from RC, now life is all about guns and long range shooting.
Have you considered one of the newer "gen. 3" lipo packs? ex. Hyperion G3 packs, Flightpower EON X30's...
The hyperions are quite good prices over last gen. lipo packs. I bought 2 3s 4200mah 35C packs for $100 each, or you can get 3s 5000mah 25C for same price, new gen as well.
