I’d love to try a 14500 with some extra capacity. The 10440’s really need some development. Not much room there though.

Thank you. We’ll pay attention to 10440 batteries. If there’s any new information, we’ll let you know.

I thanks you very more for the GAW

I like the 14500

also looking for a good 26650 for my FT03 and am checking some of your offerings

Please check our vapcell 26650 5500mAh 20A for flashlight .

If Vapcell could make high capacity 26650 cells, they would sell like hotcakes among BLF members!

How do you think the capacity of 5500mAh 26650 ? Are you interested in them ?

I’m not in, and so far these have been great performers (this is a pic of my back up set) and just wanted to say I need some kick ass 18500 cells!

How do you think about our vapcell 18500 2000mAh 5A ?

Here it is testing graph Link :

I would like 18350, thanks.

[Blackbeard]

thanks for the giveaway Vapcell, I would be interested in the 14500 cell

I'm sure those are very nice, but I dream of a 26650 with the energy density of a high capacity 18650.

(Of course, that's a pipe dream.)

I am going to order a pair of the Vapcell INR21700 5.000mAh 15A batteries soon.
For this giveaway I would choose the 18350’s.

Thanks for the Giveaway. The reviews have been positive and I see the word spreading!

[JoeRodge]

I would love to win the pair of 16340 batteries. I’ve heard a lot about the brand and would love to give them a try.

[Vaxd]

Thanks for the giveaway Dennis!

If I win I’d like the 18350’s please.

[Woody]

Just read HKJ’s review of the 18350 - looks good. They would be my choice.

[morpheus1301]

Thanks for the giveaway. I have no Vapcell batteries yet.
If I win, I’ll choose the 18350 cells.

[Sivy]

Have been a little disappointed with the capacity of my old 14500s so would love to try some Vapcell 1000mAh ones.

We are currently developing some flashlight batteries. …

Flashcell®?

Thank you Vapcell for bringing us the top notch cells. They are a real boon for our hobby.
My advice for you is: keep doing it! You may be able to top your results (f.e. with a high-current 14500). You may also consider smaller sizes. 10440? 10180? Honestly, I don’t know how big is a market for them. It may or may not be worthwhile for you. But I think it’s at least worth considering.

You may also branch into adding USB charging circuits. These are very useful, greatly improving lights that don’t support charging by themselves. These are already quite popular for 18700, 14550 and 16340 but not yet for:

• 18350
• 21700
• 26650

Furthermore most offerings use a fair quality low discharge cells (like 18650B) and high resistance circuits.
In 14550 format your 1000 mAh cell would set you well ahead of competition (which tops 750 mAh).
In 18650 the competition is much harder but you can still get among the top players by using a low-resistance circuit with a top cell like GA. You could get ahead for some users with even lower resistance - something like VTC6A?

Furthermore you can get bonus points for:

• a powerbank feature
• Type C connector on cells that are large enough to fit it (21700?)

I almost forgot:
I’m in! Would really like the 16340 cells yet I have no budget for them yet. Thank you for the chance!

Thank you so so much for your advice. :+1: :+1:

Vapcell will record it

What is the best 10180 battery in the market? How much capacity?

10440 batteries, I remember the forum members said that efest 10440 350 MAH was the best, right?

18700, 14550 and 16340 batteries with USB function, we need to develop

But could you tell me Why 18350,21700 Batteries Can’t Take USB

I noticed some 18650 batteries with PCB. We usually put PCB on the negative poles of batteries, but some flashlight manufacturers’18650 batteries put PCB on the positive poles of batteries.

Do you know the advantages and disadvantages of both?

Thank you

Then could you show me some pictures?

a powerbank feature

• Type C connector on cells that are large enough to fit it (21700?)*

I don’t quite understand.

Hope you’re lucky to get a pair of 16340

Thanks again

[madsnake]

Thanks for giveaway! If i win, i choose 18350 battery.

[Rdubya18]

Thankyou , been meaning to try some vapcells but haven’t yet. Maybe a win will help remind me on next battery buy.

…

The industry standard for cylindrical cells sets the negative pole in the cell body, with positive on top. Since protection circuitry requires a little bit of power from the cell this forces the usage of a conductive strip along the cell body on top of an insulating wrap. This poses a problem because if the cell wrap is torn or punctured near or at the strip the risk of short circuit is very high.

There are very good small p-channel MOSFETs nowadays, this makes possible installing the protection circuitry (1S battery management system) on top of the cell, at the positive pole, where the negative pole is also easily accesible by the sides. This eliminates the previously described potential short-circuit problem and the need to use two wraps, making the cell robust and safe.

Cheers :-)

Dear Barkuti

Thank you for your answer.

In order to avoid short circuit risk, we should install PCB in the positive pole.

It takes time to study.

I heard that the cost is much more expensive than the negative PCB.
