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.

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.

As the headline reads this brand of battery is on par with Fenix and Nitecore not only with their lights but these batteries as well and not only the build but quality and function as well and they perform as they say they do, so these do meet the expectations and even better depending on a lot of the lights available at Battery Junction.
