vapcell Dennis,

Why do some cells like the Original VapCell INR21700 5000mah 15A have the positive electrode of the battery recessed and can only be charged using the LiitoKala charger?
Why aren’t they just a normal flat tops? I can not charge them in my Xtar Dragon VP4 plus. Also the case with LG M50 21700’s.
Button tops, flat tops, now recessed tops? :person_facepalming: :weary:

Barkuti is right, We can make battery pack for these batteries. The battery button top are still under study and are expected to be released soon.

Thanks! :+1: Even just a flat button top that is flush or just a bit higher would be excellent. Really want to add these batteries to my arsenal!

Thanks

Thanks Chris

In case you are wondering Nite Shadow, Tesla had the idea of using an aluminum cell top in their 5Ah NCR21700. This is what is causing trouble, there's no affordable industrial process (yet) to easily attach a button top or any other sort of shim to it.

I myself have tried low temperature soldering onto aluminum with very little success and this is even using very nasty soldering fluxes. Spot welding the aluminum positive pole in the NCR21700 is a big hurdle right now, Tesla did this for reasons bear no doubt.

Cheers ^:)

I’ve got a gold 21700 in my Fireflies, works awesome, 14500’s would be great to win

Thanks, Barkuti! Much clearer story now. I just wonder why LG M50 21700 are like that too. Was worried this was a new trend and would need to get separate charger And I only like ones that charge properly per HJK.
Just don’t have room for another charger like my XTAR Dragon. I have several FF PL-47’s with Nichia 219 B’s and do not want to fry them so was looking for short 21700’s with 7-10 A continuous rating.

Thanks for the giveaway!

If I win, I’ll choose the 18350 cells !

[Scallywag]

I would love to try the Vapcell 16340 in either my D25C Ti or my Olight S1.

[dekozn]

I would love to try the 14500cells

[SIGShooter]

If I won I’d go with the 14500’s.

[Noir]

Thanks for the Giveaway.

18350 would be my choice.

[Jacksun]

I’d like 18350

[maukka]

Still waiting for the new generation of promising 16340 I ordered. I hope you get the shipping sorted.

[aginthelaw]

I would probably choose a pair of 16340’s to throw in my older, lights like D25c or s1 batons. I’d probably try them out in my hds lights also. Thanks for the giveaway

[lichtpfadfinder]

Great that you also concentrate on Cells not quite coverd by your origin of ecig batteries / vaping. The 14500 would be great to boost some AA Flashlights I still own. On the other hand I´m keen on getting a Emisar D4 with the 18350 tube, so getting a cell for that, would definitly be a reason to finally pull the trigger and buy that beauty.

[tvizk]

I’d love to try out some of your 16340s. High drain 16340s are a rare species.

[d_t_a]

I’m interested in the Vapcell batteries. Have heard good things about them, but haven’t had the chance to own any yet. Thanks for the giveaway!

[derfyled]

I’m in the hunt for the best 21700. I guess I’ll go with Vapcell.
