An Advanced and Rechargeable Battery: The MecArmy U18-34
We are really excited to talk about this innovative new 18650 Lithium-Ion battery! 18650 Lithium-Ion batteries are excellent and powerful batteries that can be recharged using a battery charger. However, the MecArmy U18-34 is a 3400mAh battery that has a USB port located right on the battery itself.
This means that there is no need to search for any battery chargers. You can just pop the battery out of the flashlight and plug a USB cable right into the battery and charge it. There is a power indicator LED located on the top of the battery. While it’s charging it glows red and when it is fully charged another LED will glow green.
