Is somebody could tell me WHY we can buy a Zippy-R, 4800mAh, 4s, 25C for $77.00USD, and a TP 3850, 4s will cost $180.00????
Somes tell that this Zippy-R have enerlands cells on it, and it's only $77.00 for a 4s, 4800mAh at UnitedHobbie.

One of my friend (E-Mike) run 2x 4800, 3s Zippy-R in it's revo and he tell me that this pack perform very welll for the price.

So what's the advantage to pay 3 time the price for another brand
