Tenergy 30016 18650 2600mAh 3.7V Protected Lithium Ion (Li-ion) Button Top Battery - Bulk

Tenergy 18650

3.7V 2600mAh Li-ion Battery

This high energy density and capacity lithium-ion battery from Tenergy is perfect for flashlights, portable power devices or other devices requiring 3.7 volts. The 3.7 Volt 2600 mAh capacity provides a long lasting, efficient discharge for maximum runtime for your flashlight or other device. The lightweight 18650 cell has been tested by the IEC (International Electrotechnical Commission) standard to ensure capacity, quality, and life span, so there are no surprises. Also, this 18650 has been manufactured under the ISO9001-2000 standard to assure top notch quality. These 18650s supply three times the voltage of 1.2V AA NiMH or NiCd rechargeable batteries. The unique patented PCB design prevents voltages outside of 2.5-4.25 volts

Note: 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.
