Protected 18650 2400 mAh rechargeable 3.6 volt battery - charge with the Ultrafire Multi-Battery charger.
The advantage of this cell is that it features a button top making it particularly compatible with many flashlight applications.
Rechargeable Lithium batteries are rapidly becoming a very economical way to lower the operating costs of Lithium-Powered flashlights.
We offer a number of different options in order to meet any rechargeable needs. These are Protected batteries.
These fully protected cells simplify usage with their integrated PCB.
Perfect for your single cell application these cells are not for pack building as doing so will defeat the PCB protection which is matched to the correct voltage on a single cell.
If you are building a pack please choose one of our other cells and the appropriate PCB.
