This is fairly high current 26650 cells.










The discharge curves looks good with good tracking and fairly constant capacity.



I wonder why there is this much temperature difference between the cells, but both handle the 15A discharge without problems.
I suspect that my battery holder was damaged and that was the reason for the higher temperature.





Here both batteries tracks perfectly in temperature (I have replaced the battery holder) and they can handle a 30A discharge, but gets very hot.















Conclusion

This cell has good performance at higher currents and a fairly high capacity.

Looks like a good battery. Thanks for the review mate

Thank you HJK!

I have the Shockli 4200mAh battery that is 67.5mm and works well in series with Convoy L6, and it is the battery I use on that light. :slight_smile:

Thanks HKJ! Do you have the Shockli 26650 5200 mAh cell in the queue? I'm totally speculating the 5200 is the same cell as the LiitoKala 5000, so if you test the Shockli 5200, I'd think we got the LK 5000 covered.

It is already tested, but I do not know exactly when I will publish the review.

I went to HJK’s Battery Comparator for bot Shockli 4200mAh and the 5000mAh batteries and found the results interesting.

Looks like a great battery. Seen a few 26650 claim 30 amp continuous but very few can hold up to it like this one. Surely some vapors who use big mods will like this battery.

Torch the battery boy has some test results of the Shockli 5200 posted here: http://www.torchythebatteryboy.com/p/imr-safe-chemistry-batteries.html

I don't see the 5000 or 5200 cells sold anywhere yet - no retailer hits I could find in google, eBay or AliExpress. It looks like the 5200 fades in the high discharge rates, but that's for vapors - I'm more interested in the 5A-10A range, and in that range, it holds a high Vf.

another nice product from shockli,thanks for the review.
