Convenience With Confidence

"Fenix batteries are so cool! Having the built-in charging port and discharging protection circuitry provide convenience with confidence. I am building RC models for my grandchildren and I know that they will be safe using theses batteries!!!"

Steven H. (5/5)

"Hands down this is the best battery I personally have ever had. I was given the Fenix flashlight a super high-powered one, by my company when I went to work mining. That was 20 months ago. And my flashlight and battery are still working like the first day I got them. I take good care of them for sure. But it still surprises me that they work so flawlessly. Hands down this is one my favorite possessions. And that's not a joke. Because when you have something that lights up the dark like this flashlight and battery, you know you're going to be okay."

Travis (5/5)

Great Battery

"Easy to charge, long lasting"

Emery P. (5/5)

Great RC project use

"Using for RC projects, ESP32. Discharge capability is great."

Samuel G. (5/5)

Works very well on my 3D printed semi

"They arrived in a nice package with no damage and worked flawlessly. They last a good amount of time. I would say they are worth the money but could be slightly cheaper. Keep in mind that before you order they sell per 1 battery and it is not a 2 pack. Overall great product!"

"Good vale, Excellent life. Last battery lasted almost 2 years and I use it daily."

Dale H. (5/5)

Excellent and longlasting

"Just purchased new batteries for my son's fenix light and after YEARS of use. I would recommend a fenix light and battery for parents to get their new drivers in case of emergency or even just to have. Worth it!"
