Zippy Compact 5S 5000mAH question
 

I purchased 4 Zippy Compact 5000mAH 5S packs over the Summer. I finally got around to getting them ready by soldering 4mm bullets to them and applying the Velcro. This is where it get interesting. Using one of the packs a a guide, I cut 4 identical pieces of Velco and started sticking it to the packs. But, on one of the four packs, the Velcro was 1/8" too wide. I initially thought I screwed up cutting the Velcro too wide, but, upon closer inspection discovered one pack was 1/8" narrower than the other three packs. The length and width dimensions are identical, but the "height" of this pack is less. The only explanation I can come up with is each individual cell is thinner, or ??

Has anybody experienced anything like this? Thanks.

If the cells balance and it charges as advertised, I wouldnt worry about it 1/8 inch shouldnt be of concern just my opinion

I was going to buy some because they had an American warehouse indicated, but the shipping was the same 52 dollars as it was from China. Did I do something wrong?

I'd weigh them. If the narrower pack weighs less by more than 10 g, I'd be suspicious.

Mine were only $24.00 to ship?

Have yours shipped? i Just ordered some more and it looks like I paid 67.00 to ship three to me. Would be awesome if they were in the US warehouse

RE: Zippy Compact 5S 5000mAH question
 

The U.S. warehouse indicated it only had one. I ordered 6 packs and received two on Saturday. I have not received the other four yet. I think I wrong in the above,. I think it was about $33.00 for the slow boat from China?

Thanks. Not sure if you have used the batts in the past, but they are awesome. They are very strong and hold their voltage under load. I was very impressed with them, and they are really light

RE: Zippy Compact 5S 5000mAH question
 

No, my first experience using them actually. I bought them as practice packs not knowing, if they would stand up. I was using a Rhino and a True RC pack several years ago. I really did not like the performance of either. I flew the P program three times with the new Zippy pack and was very pleased with it. I am also going to try the F3A Unlimited 35c/5100 as windy day packs.

Check the 'C' rating - usually the lower C batteries are a touch narrower (and lighter).

I would fly the packs and see if they come down at the same voltage. If the skinnier pack seems to come down with less energy, it's probably a smaller capacity or lower C rating.

<div style="margin: 0in 0in 0pt"><font size="2">I just experienced a somewhat similar situation as the OP except with the Zippy Flightmax 5,000 5S1P 20C packs (not the compacts). </font></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><font size="2">On <u>10/16/12</u> I ordered 4 of these packs. Their web site indicated these were the last 4 packs available. I purchased them from the US Warehouse for $39.70 each with total shipping of $16.07. I received them in good shape and they were balanced at roughly 28% charge each. All 4 packs weighed within 4 grams of each other with the lowest weight being 609 grams.

I received them 2 days ago and they were also in good shape and balanced at roughly a 24% charge. They also weighed very close to each other, however, all 4 packs were much heavier with the lightest one weighing 651 grams. I'm thinking "what the heck" so I compared them. They had the same exact labels on all 8 packs yet the most recent 4 packs received were about 1/8" thicker in size and over 40 grams heavier each. </font></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><font size="2">I have no doubt that the newest packs will have good performance but they are definitely heavier and slightly larger than the 1st batch Ireceived just 2 weeks earlier.</font></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"></div>

The Zippy Flightmax 5S 20C use to be listed at 620g. I have a set that is a couple of years old that are 625g with Dean's connectors. I just looked at the Hobbyking site and they are now listed at 640g. Looks like Flightmax is making some changes!

RE: Zippy Compact 5S 5000mAH question
 

FWIW, all 4 packs have the same labels and identifying marks, one of them is 1/8" narrower.

I flew my new (to me) Xigris yesterday with these batteries. The flight seemed OK (plane is still very new to me, I don't think I would have noticed any slight variance in power). But when I recharged the pack, one of the cells had triple the impedance of the other 4 cells (8.7milliohms versus 2.8 milliohms)

I'm guessing the pack was somehow mis-assembled and the high impedance cell is a lower mAH rating than the other 4 (5000mAH). I am WAY past the Hobby King return windows for batteries, the downside of buying in advance.

The "regular" Zippy 5000mAH 25C packs are performing well so I will likely pick up a couple more of those and chalk the bad Zippy Compact pack up to experience. I'll wait to just before the start of next season before buying any more packs so I can try them out within the warranty period.
