I just bought 3 from there. I really like the battery, so I thought, I better stock up on a few more before there gone.
The keeppower is the same battery from what I have seen of HKJ’s testing as mentioned above.
Hey guys, these are indeed discontinued, but we have a replacement now. The Vapcell 18350 is the same thing as the Aspire was under the wrapper, and we now have them in stock.
Thanks for that info. I got three of the Aspire 18350s and two of the VTC-5As from you before 1/20, when my Emisar D4 arrived. I’m good for now, but it’s nice to hear about our options.
Not doubting what you advertise, just want a confirmation.
You website states max discharge 10amps. no word of the 15amp pulse rating…? Have they been tested for capacity, are they truly 1100+ 10/15a like the aspire…?
The Aspire 18350 1100, were rated at10/15amp, 10a continuous and 15amp pulse for up to 10seconds.
HKJ tests have confirmed this rating.
My Aspire’s will do 15+ amps pulse on my D4 with a reasonable/acceptable voltage drop no problem. Aspire is/was the best 18350 I’ve used by far.
Will your Vapcell 18350 do this also without a drastic voltage drop like most all other 18350 have…?
I do need to order some 18350, but want to be sure of what I’m getting.
Yep, it’s the same. Here’s a pic of the 15A pulse test, 10 sec on 5 sec off. You can see they’re within test to test variation of each other. Vapcell has been very conservative with their ratings so that’s the only reason for the difference in published numbers.
The battery itself hasn’t been discontinued, just Aspire (the E-Cig company) isn’t putting their label on them anymore. Which is somewhat strange since Tony (owner of Aspire), apparently has a stake/part ownership of this Yongdelli battery company. But like any Chinese company, if you order enough of them, they will make them.
Also, the flashlight business isn’t even a blip on these battery manufacturer’s radar. It’s all about the world-wide e-cig business.
They actually have some pretty cool subtle white flowers that look like they’re straight out of a Japanese garden around the negative end, definitely the prettiest battery I’ve seen recently. So there’s that
I wish there were more 18350 flashlights. Now that we have a decent small cell it should be the standard for all new smaller lights that typically would take the RCR123. Unfortunately being a little wider and more than a little late it’s not going to happen very fast if at all.
I wished there would be a better 16340 cell. There used to be a high current 550mAh AW cell (the AW 16340 15C) but that one has been out of production for ages. I bet that if the right manufacturer is willing to make it, a 800mAh high current 16340 cell should be feasable.
If you go by cell to cell volume, and use what ever they figured out in the 18350 cell, A little over 800 mah should be possible.
The best high current 16340 cell I have tested is the Trustfire IMR16340 650 mah. Who would have ever guessed, someone figured something out that worked better over the pond. Still not on par by volume with the 18350 cell but maybe its coming.
If my math is anywhere near correct, applying the Aspire 1150maH 18350 tech to other form factors should give us about…
32650: 9051 mAh
26650: 5587 mAh
20700: 3197 mAh
18650: 2262 mAh
18350: 1150 mAh
14500: 870 mAh
16340: 817 mAh
10440: 272 mAh
10180: 95 mAh
Something doesn’t add up there, since some of those are way off. Like, 18650s are up to 3500mAh now. Perhaps we should look at how things might be if we could apply 18650 tech to other sizes:
32650: 14000 mAh
26650: 8642 mAh
20700: 4946 mAh
18650: 3500 mAh
18350: 1778 mAh
14500: 1346 mAh
16340: 1264 mAh
10440: 421 mAh
10180: 147 mAh
To estimate, I’m just multiplying the volume ratio by the capacity, where the volume is estimated as the inner cylinder with a wall thickness subtracted from both diameter and length. I tried a few different wall thickness values, and the thinner the wall the better 18650 looks compared to the others. These values used a wall of 2mm.
