The protection limits the current from this cell to less than 3A, the curves looks good enough.

With this low current there are absolutely no temperature problems.

Due to the low protection threshold the battery cannot drive a 10W light.

Something is wrong here, a 2500mAh battery has sneaked into the 2200mAh collection of 2200mAh batteries. This makes me doubt the quality control.

Both types of batteries handles stays cool.

Conclusion
Due to the low protection threshold these cells are not for 1000 lumen flashlights, but only for equipment with a very moderate current consumption.
Generally these batteries has looked acceptable, but the 2500mAh cell is strange.
Notes and links
The batteries was supplied by TMart.com for a review.

Buy one cell and get a bonus 300mAh’s in the next batter. Facepalm
Thanks for the review HKJ.

Well, not useful to me. Thanks for doing the testing, HKJ! I had been curious about these after seeing them featured in some adverts! Now I know: AVOID!

Okay, well, I’ll still avoid, just because I’ve already got dozens of laptop pulls that probably will perform at least as well as these – or better! Wink
