The battery is great, I have it in several different sizes and it hasn't caused me any trouble. The capacity is as stated, or even larger. I haven't noticed any self-discharge, and I rate the price-to-quality ratio as 10/10.

Excellent battery, I use it interchangeably in the Nitecore P30 and haven't encountered any issues. The price is reasonable, and the maximum discharge current is 10A, so it has no problem handling powerful flashlights.

The battery has the same dimensions as the 21700 model from Olight and fits my Olight Perun 2 and M2R Warrior flashlights, but works exclusively with the Perun 2. It seems the differences in contacts cause the Xtar battery not to be completely metallic on the positive side. Besides that, it arrived already charged.

Great batteries, I have them in various sizes and capacities and never had any problems with any unit. They have overcharge and deep discharge protection, so it's really hard to damage them.
