The discharge curves tracks nicely and the 3A rating looks to be about right.

Conclusion

This looks like a good high capacity 14500 cell, it handles the rated 3A current nicely and it do not fall flat if more current is drawn.

Looks to be a great 1 to 2 amp cell with very good capacity.
At 3 amps voltage sag sets in but it still has better capacity and less voltage sag than most 14500’s. Above that and the Efest purple takes over.
Thanks for test data HKJ and all the other data you have contributed. Thumbs Up

Thanks for the test! Smile

I like this new generation of 14500 batteries, I have 4 of these now and they caused renewed interest in my 14500 flashlights. Your comperator shows that up to 2A it performs similar (slightly better) than the Soshine 900mAh 14500, but at 3A it clearly outperforms it.

It will be nice if they ever catch up to peak 18650’s. I don’t know how it looks internally, but just using external dimensions and simple math, 14500 is about 46% volume of 18650. These “High Capacity” cells are surely better than the older generation cells rated 800mAh or less. But, if it were even close to representative of the volume relative to 18650, then over 1500mAh should be possible. I’m pretty sure we’ll never get that, because the development isn’t worth it for comparatively puny sales.

Thanks to HKJ for doing the testing and sharing it with us here!

Great review as always Thumbs Up I’ve been keeping an eye out for this one as it’s something I’m interested in!

Never say never Wink again.

The stuffing is already developed. Better small cell technology is anent to convincing a proper OEM into doing it. I am sure many chinese battery OEMs producing good 18650s could do it (Heter, Lishen, BAK, etc) or something pretty close, another thing i$ convincing th€m into doing it.

14500 has more invalid space and can not increase the capacity of batteries, such as steel tubes of equal thickness, positive parts of batteries, and internal structure And many 14500 sizes are only 14*49mm.
Thumbs Up I was about to say the same thing. You can’t just compare the volume between the 14500 and 18650 because there is a higher ratio of unusable space in a 14500 cell compared to 18650. Getting 1,000mah out of the actual volume that can be used for energy storage is pretty amazing already. Even the Sanyo/Panasonic cells can only get 840mah.

I wouldn't call that amazing, it's more like there's nothing better. There could be something much better.

Sanyo/Panasonic stopped developing 14500s years ago, probably a decade already. If they were to use their current technology in 14500s we would see 1500+mAh cells with higher discharge rates.

Structurally speaking a 14500 can does not need to be as hull thick as a 18650, so while the useable space argument is valid, it is also invalid to me.

When you consider that it takes so much space in a li-ion cylinder battery for the anode and cathode and the casing, the available space for the electrolyte decrease as the sizes decreases.
If you had a 18500 battery (50mm length) and it takes 8mm for the anode, cathode, button top and CID and a little space left for the connections.
That’s 16% of the battery space length used just to make the battery and 84% left for the electrolyte.
Now if you make a 18250 battery (25mm Length) you still have to have that same 8mm just to make the battery, but how much is left for the electrolyte.
25mm – 8mm = 17mm left for electrolyte. That’s 32% of the battery space length used to just make the battery and 68% for the electrolyte.
18500 84% electrolyte
18250 68% electrolyte
Same thing happens when you start shrinking the diameter. Making a thinner case as Barkuti pointed out or figuring out a shallower way for the anode and cathode might improve more space for the electrolyte.
