UltraFire LC 18500 1600mAh 3.7V Protected Lithium Ion (Li-ion) Button Top Battery - Bulk

This cell is 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 and should not be welded or soldered on which may defeat pr daamage the PCB protection. If you are building a pack please choose one of our other cells and the appropriate PCB.
