I love USBC 21700
These 21700 batteries with USBC are top notch! Definitely recommended.

Strong battery.
An excellent balance between amperage and capacity. This battery (in combination with the efficient and well-regulated drivers Acebeam uses) produces long and sustained run-times. The onboard USB-C port can be a convenient feature if you are found without a charger in an emergency. Just be aware this 21700 battery is 5mm longer than standard flat-top and is not compatible with all flashlights.

Quality, high-capacity battery.
These are good batteries. The USB-C port is very useful, and these batteries are also great for many devices other than AceBeam torches. Works great as a power bank - 5100mAh is quite a high capacity.

Long Run Time
Keeps you going longer with great runtime!

I want one more!
Great capacity and charging method. Smaller than many mobile batteries so also great for EDC mobile battery.
