Latest release Vapcell 21700 5600mah 12.5A battery

Thanks, could you let me know why it doesn’t work in the Eagtac

The head doesn’t allow it. Looks like button top only.

EagTac

Reylight

I dont have those lights, so I cant check… this is just a guess:

probably the button on the Vapcell is shorter than on the Efest
and if the D3a has a raised ring around a positive contact button in the head, (physical anti reverse polarity), the battery + cant reach the + contact in the D3a head…

Im guessing the Reylight either uses a spring at the positive contact, and or does not have the raised ring.

a pic of the inside of the two lights heads, and of the two batteries standing side by side showing the height of the buttons, might shed some light on the issue.

bingo! the positive on the ET head is recessed, the positive on the ReyLight is raised
a small magnet on the Vapcell might solve the issue with the ET recessed + button…
but caution! we dont want the magnet to short the positive contact to the ring, if it is ground…

I thought about that but it’s not that big of a deal. I don’t carry the EagTac that often, I mostly carry the Reylight.

good attitude :slight_smile:
and thanks for the pics
can you please also show the two batteries positive contacts?
Im trying to see if the Efest button is taller

Sure gimme a sec……

Vapecell is shorter. This is an older trustfire which is the exact same size wise to the efests. The efest is in a light at work currently.

You could add something like this to the driver but that take away the reverse battery protection (second pic). I would assume it probably doesn’t have a electronic protection that’s the reason it has a mechanical protection. So you’ll have to be carefully to make sure the battery is inserted correctly.

I was actually thinking just a dab of solder should do the trick lol.

That work too, but it tends to oxidize in a few uses. Works fine as long as you clean it ever now and then.

You’ll probably find the MRPP ring is soldered onto the driver.

My low temperature Bi50Pb32Sb18 blob converted cells do not suffer from oxidation on the top.

How much money are you paying for Eagtac or that sort of manufacturer flashlights? In my opinion paying good money for something and receiving such a piss-poor “@#$% consumer battery choices” reverse polarity protection solutions is very bad.

:-)

Hi, in the thread title you are saying $6.99 per pair - meaning two cells (ie $3.50 per cell).

However your Aliexpress listing says $6.99 for “one piece”.
https://www.aliexpress.com/item/4000108417629.html

Can you clarify how many cells are included?
$6.99 = two cells?
$7.99 = four cells ?

sorry, I correct it . usd7.99 /Pair

Are those suitable for flashlights?

I often see these claims in battery advertisements, and sorry to say but that is wrong. Batteries can be used to power up a multitude of things. I could use a battery to power up a personal vibrator, for example.

The pertaining question here is, ¿is the flashlight and its driver designed to make use of such battery? Also, ¿is the flashlight user knowledgeable and responsible enough to properly take care of it?

I am not aware of flashlights designed to be powered by 26650 LiFePO4 cells. This could be useful for very low Vf leds and linear or unregulated drivers.

After the very good experience with the Vapcell support during my last order i ordered the 18350 cells now. DHL did not leaf a message that the package is ready for pickup in the Post office 150m away.
So the package was send back. Instead of asking me for money (thats what AE usually does) the Vapcell Support contacted DHL and managed a second delivery for free. 1A Support and fast help.
And not only the support is great i can only say good things about the cells. Untill the next buy.

I’d like to check out the Vapcell S4 Plus charger, but going to the AliExpress link, it indicates “cannot ship to my country”…

Why not LiFePO4?

Like above here's the link “international/english version” fixed: https://www.aliexpress.com/item/4000249374391.html
