Zippy vs Enerland - performance > price

[Sammus]

HC say that the zippy-r's use korean cells but wouldn't disclose who from (apparently part of a privacy agreement), whatever that means. I know enerland and kokam are two reputable lipo cells manufacturers in korea, and know of none others. I've also read about plenty of problems with zippy-r packs. That said, I have a heap of zippy-h packs which go alright for cheapo's, and I've also read about plenty of problems with the mamba monster but am yet to experience any :D
