Acebeam 21700 Li-ion Battery

The Acebeam 21700 Li-ion battery is designed for powering high-drain LED flashlights, including the tactical T36 (sold separately). This rechargeable IMR battery has an impressive 5100mAh capacity that can be used to power the T36 light for 20 days. The Acebeam 21700 battery features lithium manganese oxide chemistry, which provides incredible stability and power. In fact, this rechargeable cell is able to provide up to 20A of current, thus making it the perfect power source for premium lights and other portable electronics. The Acebeam 21700 battery is a larger and stronger power source than the more commonly-known 18650 and will take your premium devices to the next level in performance.

The protection features included in this battery make it slightly longer than the average 21700 at 76mm.

While most spring-loaded battery slots adjust for varying battery length, we still recommend checking with your device's user manual for battery compatibility.

Doesn’t work in Olight Flashlights but works in Fenix
December 6, 2021
Good battery and 5100mah is accurate - just one catch that surprised me. I charged them up and tried these in 2 new Olight flashlights that had Olight 5000mah in them which were working perfectly. The flashlights would not come on. I assumed they were defective, but measured the voltage at 3.75V, so tried them in a Fenix and they worked. I suppose the Olight voltage regulator didnít like the added 0.15V.
Anyway just a heads up if youíre planning to use them in an Olight this might save you some money.
