Got a few V11R’s that need good 16340s as that o-ring groove just doesn’t leave enough meat for boring for 18mm cells

Dear Djozz

Thanks you very much

16340 battery,it seems that progress has not been made for many years. We are looking for a better 16340 battery.

I have questions to consult you.

What is the main purpose of this battery? What is the market share of battery power requirements compared to 18350?

Look forward to your reply Blushing


Hi Dennis,

The main purpose of the 16340 battery is flashlight use. Many popular pocketable flashlights are on the market that make use of in the USA widely available (non-rechargable) CR123 batteries, these flashlight are often used with (rechargable) 16340 batteries.

The 16340 is noticably smaller than 18350 batteries and flashlights for 16340 batteries are often used in the pocket of your pants, while 18350 flashlight are found by many people to be a bit too big for that.

The market share in general is not high (the 16340 is not used much in vaping), but for flashlights the 16340 is a very common battery.

As Djozz has stated, a number of compact flashlights use CR123 and are compatible with rechargeable 16340/16350s. Current draw for these applications is 1-3Amps most commonly. But the nature typical of BLF forum users are to prefer higher current capable cells. So continuous 5A would be a good limit for this size cell, in my opinion. I feel that a minimum requirement is at least STRONG performance at 3A.

This is very exciting news! I love the 14500 size because I have a ton of AA/14500 lights that can use this. I have a number of Sanyo 14500P but always wish the capacity can be higher. This will help a bit. What cell is under the wrap? Surprise it can beat the Sanyo in energy density.

Also, did you send the Sanyo NCR21700A to HKJ for testing? Really like to have that on his comparator. It seems to be the best 21700 for most flashlight use cases unless very high current is required.

Very interested in this 14500.

I have a number of 14500 flashlights and so far the best high-drain cells I have only hold 650 mAh.

Question on your new 14500s Vapcell: What is the sustainable current? 3A? 4A?

On one of these cells, you can read “Max continuous discharge 3A”

Anyway, looks good. The price is secret intentionally?

Thanks, HKG. The protected cell form factor (apparently) receives little love of late.

This is not a protected cell, it has no electronics that prevent overcurrent or overcharge/-discharge. The PTC is a one-time fuse that will blow in case of a direct short, all li-ion cells from major brands have that.

Interested.

But the Vapcell AliExpress store doesn’t seem to ship to my country, the Philippines.

Is there some way to have it shipped in a reasonable price?

Nice but it would be perfect if there were new 16340 cells. By far my most used cells.

This can be 14500 battery with pcb. protection of current and voltage

But it will increase battery length.

(djozz) Thanks for the clarification.

(vapcell) Thanks for stating the obvious and the offer of making something happen if needed. I have never witnessed such hostility on this forum to the protected cell form factor. As folks are heaven forbid injured moving forward it will unfortunately be difficult to spotlight but not hard to explain.

Thanks for endorsing progress here Dennis. Me and others would also have liked a higher drain cell, but thanks anyway. The pricing is fair also. Thumbs Up

The only 14500s I bought more than a couple years ago are installed inside a li-ion converted hair clipper LoL! Big Smile

 

Cheers Smile

P.S.: will post this at ForoLinternas' Recommended batteries updated thread, deserved it is (link to mentioning post).
