Mislabelled packs?
Hi guys,
I bought a new set of 5s 5000mah Zippy packs from HK and wonder if they've been mislabelled? Two things stand out...they're heavier than my other 5s packs (1200-1270grams), at 1360grams, and they're also fatter (wider). I'm wondering if maybe they're actually higher capacity than 5000's?
Don't know if this means anything, but after I charged them the first time I tried to break them in with gentle running on the plane (about quarter throttle only for 6:30 minutes). Then when I went to charge a second time to storage charge I couldn't! Kept getting "bad S count" on my Cellpro. I was able to use the 0.1A charge setting and saw it was at 45% capacity but the cell voltages still read 4.0volts (also all cell voltages were almost the same).
Any thoughts?
Cheers,
Ken

RE: Mislabelled packs?
The 'bad cell count' could be an indication of a bad connector or connection with the balance leads. It does sound like the packs may be mislabeled. Contact HK services, there have been a few reports of the wrong labels on packs. I bought 3 small packs for a foamy this spring and one of them was the wrong size. Label was wrong. They fixed the problem.

Ken, I had the same thing happen to one of my packs (Zippy Compact 25C-5000) I gently broke it in at 1/4 trottle for 7 minutes and I got the same thing( The out of the box capacity was 24% and the other were 50% or above). I am using them as practice packs anyway and for now local contest packs. The other 4 packs are still doing fine and the Ohm's are still low after 30 flights 1.8 low to 3.1 on the high and thats consistent with all the packs. I have worked a few of them very hard testing and setting up ESC lately.
