Happened during driving.

4s 5000mah 20C Zippy-H. I had driven ~30 charges with it before this happened. Temperatures been ok and all. Was on 1/8 buggy conversion with mamba monster and 2800kv xl-motor. (maybe 6 charges with this car, then with old cars, inferno and mt2) Charged with balancer and 1C or less.

A fiend of mine had a similar failure on a Zippy 5s 5000 pack and I had a 5s 4000 pack where one of the main leads was not soldered on properly. I was able to fix it myself on the 4s 5000. This is out of about 8 packs between us. The zippy are for sure great bang for the buck, but with the lower cost comes a lower lever of quality. I expect that they will have a few issues here and there, and in all honesty they haven had any more issues than I have seen with more expensive packs failure wise, but I do think there is room for improvement from an assembly standpoint.

But then again.... Its half the price of the "other" lipos so what do you expect. I'm satisfied with the dollar to performance of them.

So it is probably worth getting them, taking off the shrink and checking all of the connections. I would then wrap them tightly in clear tape to counter cell shifting and then resolder all of the mian leads and balance wires. As cheap as they are I would be happy to get them as loose cells that were matched and just put them together myself...

Has anyone tried purchasing the Zippy R's Hobby City has none is stock would like to get a couple more.

Is this true?!?! I was just about to buy some because they were the only lipos that I could afford in numbers that would handle a Neu.


EDIT: How would these compare to the Zippy R's ? http://www.hobbycity.com/hobbycity/s...idProduct=7298

HobbyCity are now offering the smaller individual cells so we can hope that they eventually offer the 3k+ cells and prefferibly the 5k cells for us to build packs to fit our needs. We can only hope!
