Wondering if these are any better.... I am a fan of the turnigy batteries in general, but I am slowly switching over to the hyperions because they are so rock solid. Still, always looking for something strong at a goood price point.

I wonder why there are no decent sized 4s packs? 2200mah is the biggest.
