My Lipo charger can't recognise a battery at all which led me to believe the circuit wasn't complete ie a soldering connection had come loose.

I then did a quick google and saw on another RC forum that many people were having issues with the soldering between the 2 cells coming loose, and splitting the hard case, resoldering and sealing up again. I daresay this is my problem. By all accounts the cells themselves are quite good but the build quality average.

Has anyone else had this problem with their pack's totally quitting?

Steve

3 out of 10 packs died, just opened them up and fix the connector. No problem since.

Good info on the soldering job, or lack thereof.... My battery has been great so far.

Fingers crossed, knock on wood!

I had a similar issue with one of my 2 packs, took it apart, resoldered the cells on the end, good to go. Plenty of rip and run time. I'll agree that the build quality is average, but hey for the price, I don't mind having to do a minor repair.

I think the issue is in the fake deans.. my charger would not recognize the batts with these.. changed them out, and everything is good...

Not all feedback on the site on the Zippys are good, some cases of DOA packs and poor soldering jobs. Looks like those feedback are more recent too. From feedback here, just touch-up on the soldering job is all it takes to make this a great pack?

Have you guys looked at the recent customer reviews on the Hobycity web site on these batteries? Evedently the quality control at the manufacturer has gone right down the toilet, because almost all of the reviews this month have been extremely bad.

Check out the reviews: http://www.hobbycity.com/hobbycity/s...25C_Car_Lipoly

I personally have no problem opening the case and resoldering the leads for this price. If there is a comparable quality pack anywhere for even close to this price then I would buy it instead. But the reality is there is nothing close to this for the same price point. Closest I know of might be an SMC or Yeah Racing. Almost all the complaints are about soldering, so open the pack, de solder the old stuff, sand lead, re solder and enjoy. If they would just ship me my 4 packs that would be great. I am sick of waiting for them to get in stock.

Yeah, I've been watching the stock levels. At one point they were like -150. Today they are at -120, and the restock estimate is late Feb. I just can't understand why the quality control would head south so quickly. Did they replace all their workers with trained monkeys or 4 year old children? Shouldn't HAVE to tear the packs apart and resolder.

1396 Available in stock as of 1 min ago. Picked up 2 more. Only had to resolder 1 of the 3 packs I already own. Was using it in my SLASH and all of the beating that truck gets, I'm surprised that it didn't fail sooner. Been good to go ever since.

Really for the price you can't beat it. My .02

Could you explain how to open these packs the easiest way?

I have tested the Zippy's side by side with SMC 5000Mah 28C packs, voltage is about 7.1V as opposed to 7.2V for the SMC under 35A discharge. (My Turbo35 isn't very generous voltage wise )

IR is a lot higher than the SMC's, can't remember the exact numbers.
On the track the packs do fine, no complaints from me for that price
