I appreciate the replies guys. I think I will go with the Zippy-R 4800 6s pack. It is supposed to be better than the 5000 pack, but not as good as the 4000 pack, but I need the extra run time. I can also get two of these the price of one Enerland cell pack.
Does anyone know where I can get an adapter from the JST-XH balancer tap to a Hyperion or Flightpower tap?
Thanks again guys!
Edit: Two more replies... thats great to hear jhautz that the temps of them are so low. Sammus, you have heard of problem with the Zippy-R packs? What kind of problems exactly? You think it would be better to go with the 5000 or 4000 packs instead? I also have two perfectly working MMM ESC's.
