Won't fit in an Astrolux FT04

They are too fat to fit in the carrier. They are good batteries though. Fast shipping.

Bought a couple of these to replace originals of the same brand, which I had accidentally damaged during recharging. These have performed well to date. Docked a star for the color scheme which is exactly opposite the original batteries, which can make placement of positive/negative challenging in low light conditions.

One of few High Drain >10A Protected Batteries
August 28, 2021
I bought two of these batteries for use with my Acebeam TK18-AL (OSRAM). These are the only protected 18650s that I've found with a high current rating above 10A which is nice. The internal resistance of these batteries is also the best I've seen at 10 mOhms give or take a few. They tested out a bit lower than their rating on my Xtar VC4S at 2900 mAh. That charger seems to test batteries out to around 10% below their rating in general so I'd probably put that difference from the rating on the charger more than the batteries themselves.

Great Price

I use these batteries in my Acebeam X80 25000 Lumen torchlight. They work very well and they are cheaper that some other resellers. Customer service is great as well. I prefer to buy them from Battery Junction because they are real people unlike ebay where if they send you the wrong thing you will be playing the waiting game.
