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.
Notes and links
The battery was supplied by shockli.com for review.
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.
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.
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.
