my Turnigy packs last around 200-250 cycles. I've owned about 30 packs, and have yet to recieve a bad one. They aren't 'b' grade in any way.
if you are going to pull high amps, go for the 30 or 40C, as they will run cooler and last longer. 20c zippys wear out after about 100 cycles when run near their max rating, especially in a hot australian summer.
I would stay away from the HK batterys. The are a second rate battery. With the advertisement and the hiring of people to represent their products in the forums and paying them for praising a poor product it's hard to trust when you are getting good reliable information or information that someone is getting paid to give.
It's a proven fact that HK pays people $100 per month to promote their products in the forums. Buyer Beware.
