The battery is great, I have it in several different sizes and it doesn't cause any problems, the capacity matches or is even higher, I haven't noticed self-discharge, and I rate the price-to-quality ratio as 10/10.

Fantastic battery, I use it interchangeably in the Nitecore P30 and have never encountered any issues, the price is reasonable, and the maximum discharge current is 10A, so it handles powerful torches without any problems.
-
The battery has the same dimensions as the 21700 model from Olight and fits my Olight Perun 2 and M2R Warrior torches, but works only with the Perun 2. It appears that differences in the contacts mean the Xtar battery is not completely metal on the positive side. Apart from that, it arrived already charged.

Great batteries, I have them in different sizes and capacities and have never had any issues with any of them. They have overcharge and deep discharge protection, so they're really hard to damage.
