Vapcell INR14500 650mAh (Blue)

Official specifications:

Model: INR14500 650mah 7A button top
Size: 14.0*49.0mm
Nominal voltage: 3.60V
End-of-charge voltage: 4.20V
End-of-discharge Voltage: 2.5V
Typical Capacity: 650mAh (0.2C discharge)
Min capacity: 600mAh (0.2C discharge)
Weight: Max:22g
Internal resistance: Max:25mOhm AC 1kHz
Standard Charge: 500mA,CCCV 100mA cut-off
Charging Time: 2.5hours(standard charge)
Quick Charge Current:1000mA

AA sized LiIon batteries from Vapcell.

The two batteries matches fairly well and it can easily deliver the rated 7A.

Internal resistance calculated during discharge by pulsing 0.5A on and off.

Conclusion

These batteries are not the highest capacity around, but they can deliver a lot of current for a 14500 cell.

Now that’s something that makes 14500 lights interesting.

Agreed! :+1:

EDIT: Just looked at these compared to the Efest Purple from 2017 in the comparator. The 2017 Efest Purples still beat this new cell, but it’s close.

Thanks for your review.
But for the moment I’m not kissing my IMR14500 Windyfires goodbye.

At low currents Efests are better. But they collapse at 10A.
Vapcell and Enercig EC-14500HP survive even this kind of current. Vapcell holds higher voltage while doing so (but ends up with less capacity).

IR? Vapcell 9 mOhm, Enercig 11 mOhm, Efest 13 mOhm.

Thanks HKJ!

China li-ion cell manufacturers used to show higher variances in their products. HIBATT IMR 14500 700mAh, Shockli IMR 14500 660mAh, Efest IMR 14500 650mAh, and this Vapcell INR14500 650mAh, they all seem to be the same cell from the same manufacturer. Their performance, however, vary from batch to batch, the differences you see among them are because of different grades and/or cell inconsistency within a batch.

But they are still the best high-drain 14500 you can find. Among these choices, Shockli and Vapcell seem to be the only two that offer a native (NOT welded) button-top version of this cell.

In the beginning, Vapcell only sold the flat-top version of this 14500, and unfortunately the batch they got at that moment was poor (I did buy 16 pieces and tested them), the performance was noticeably worse than all the other choices. I’m glad that they are now offering a native button-top version with acceptable performance.

This is simply the best high drain 14500 on the market. Someone please test this in a GT Micro.

Agree. And it is no good. Curious related article: Kaizen vs. Chabuduo: Changing Asian Quality Culture.

Nothing new. By the way, cylindrical cells are not manufactured with button tops. And they are welded. Your bad experience, toobadorz, with button tops is due to shoddy work.When a button top is properly welded it works very well and without issues. Here is a picture of a 18650 cell from which I removed the button top to take a peek at its actual flat top; I still had not fully finished the work, you can see a leftover dot by the left:

I could count a total of six (dual maybe) welds around the button. I first had to use my rotary tool attached vertically to a vice with a milling bit so I could slide the cell flat under to remove the bulk of the button top, then proceed with some hand finish work with a grinding stone. That @#$% was not meant to break up easily!

Cheers :-)

For 18650’s, I think you are right. But for some other sizes like 14500, 16340, and 10440, there are indeed some China manufacturers making a native button-top version. “Native” means that the top installed by the factory is already a protruding one, as commonly seen on AA or AAA batteries. The reason is simple, when there is a need of enough quantity, they can make that for you

For example, DLG is a China li-ion manufacturer that offers both flat-top and button-top versions of 14500. This Soshine battery HKJ ever tested is simply a DLG NCM14500-850 with native button-top.

I don’t know if you’re right or not about the Efest. I haven’t ever used them in a high drain application. But according to the HKJ testing, the Vapcell aren’t really good at 10A either. Maybe you got better cells than he did?

Hello, just curious. Does anyone know of a 14500 flashlight that puts a 10 amp load on its cells? Or even a 5 amp load? I have a manker T01 and MK41 and to my knowledge these lights are only drawing 2 or3 amps per cell. anyone??

Not so much stock flashlights but any modded flashlight with direct driver (I like the good old BLF-A6 driver very much) and low voltage led (like the Luxeon V or Oslon White Flat, and quite a few others) will draw 5+ amps from a high drain 14500 easily.

Anything with a FET driver. Some people have modded AA Tool’s or other lights with FET drivers to make them 14500 only.

No, I don’t have them. And I don’t have any 14500 light yet. Just looking at the graph they seem to deliver almost 600 mAh at 10A.

Okay, I just looked at the Comparator again, and I see what you mean. The Vapcell does falter, but not nearly as badly as the Efest Purple, and it does still maintain most of its capacity.

The output voltage of this cell at 10A is crumbled enough to hardly be of any use in any single emitter build. Even 7A would hardly be seen in practice except for a few seconds maybe.

For people who generally do not charge their cells to the max, the above is even less likely.

7A and a 2mm White Flat will work, with a littlebit voltage spare for circuit losses. But that is the lowest voltage high current led around.

The Emisar A1 needs a very high output 14500 like this.

Unfortunately, the only place I have seen an Emisar A1 is in my imagination.

d_t_a · 2019-06-28T06:37:39.000Z

GT Micro, BLF X5, Klarus XT1A I think can draw 4+ Amps.
