How are Zippy Lipos???

Just if you don't know, under the ESC the rustler has a little bit of space. If you take that plastic thingy from the chassis the LiPo must fit in. ( Maybe I'm gonna do that )

Sorry for my bad Englisch, Im dutch

True, but they are still a little too wide, unless you really dremeled your battery tray.

I have a VXL rustler and I had a similar problem when I tried a True RC 4s 5000 pack, I tried dremeling the hell out of the battery compartment and after getting tired of the burning plastic smell, I deceided to install the pack on its side. I drilled holes in the bottom of the battery compartment and used zip ties to secure the pack...I have had no issues with the pack moving and I charge the pack while in the rustler.

what balance tap does the zippy use ??i can't seem to find a plug that will work with the Zippy's ...thanks

Yes that gives you enough space to fit 7 cell flat packs as well. Friend of mine did it.

One thing I've noticed with the zippys is that their shrink wrapping is not great. I have blue H packs and the green ones. I had to wrap electrical tape around the green packs to keep the cells from shifting. On the H packs where the wire exit, the shrink wrap eventually cuts into the wire insulation.
I was about to connect one of the H packs to my cordless weedwacker when it shorted rsulting in the following photo. No flames just a ton of smoke. Only 2 cells (6s pack) vented. Overall the performance have been great but I'd recommend re-doing the packaging especially if off-roading or jumping.

I run these packs myself and love them. I'm glad you posted this, I am going to look into insulating the wire to prevent this from occuring. I run the 3s 5000 packs and haven't had any shifting problems as of yet. Its good to note that there were no flames or explosion.



On another note.... Cordless weedwacker???

I've got a craftsman cordless that worked off 2 12vdc lead-acid batts in series (24vdc). Well batts went dead and killed wall charger too. Total to replace was around $55. So instead I killed a $100 6s lipo. Probably was lucky it wasn't in my maxx though.

btw I think the short occurred at the point were the wires are soldered to cells. But as mentioned before I think the poor wrapping is to blame probably weakening connection after crashes.

I'm reluctant to cut into the packs and see if there may be a reason to worry. The wrap is a little sloppy, but for the money these are great LiPos. I think I will trim the blue wrapping back a touch and drip some rubber cement in there to try and seal up any movement.

cant you guys just shrink wrap them like 2 more times?

Sure but I believe his packs shorted inside the shrinkwrap. Where the power leads eject from the cells. So an extra layer of wrap wouldn't help that. It may help his pack from shifting, but a 6s pack is very tall. My 3s doesn't have the shifting problems. I am going to do as mentioned above with some rubber cement to prevent the wires from shifting and possibly shorting.

[rabosi]

The size of the 6s pack may indeed be a factor esp. on crashes. Also for on-road use I think they'll be fine since they won't be jostled around as in off-road use. Good idea about the rubber cement. I may do that with my 2nd pack because i also don't feel like cutting into it.

I have a Zippy-H 5000 mAH 5s1p pack and have cycled it about 5 times so far. Not really enough use on it to say for sure but they seem fine. IMO it holes voltage better than my 2x 2s 8k Maxamps setup that I was using before (still use it, but the Zippy is so much more fun) but it doesn't stay balanced as well as any of my Maxamps packs. So far it looks like an excellent battery for the price though. I bought a Hyperion adapter for a Hyperion 0606/0610 charger and hooked it into my oldschool LBA10 balancer and it balances it fine.

Did I have bad luck or what? http://www.aijaa.com/img/b/00772/3081841.jpg
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.
