14.8V 2600mAh 18650 Lithium Ion Battery Pack for Sweeper
Introduction
The 18650 battery pack is one of the most popular lithium-ion battery packs available today. Powered by the 18650 battery, it is very reliable and boasts an excellent cost per kilowatt hour.
The 18650 battery pack is commonplace for consumer electronics, electric vehicles, and energy storage systems. It can be found in medical devices, robots, industrial instruments, military equipment, and more. A custom 18650 battery pack may include battery holders, a PCB, PCM, BMS, cell balancing board, or other components.
Note: The voltage of li-ion cells is 3.6V—but some misleadingly mark cells as 3.7V. This causes battery pack ratings of 11.1V (3S), 14.8V (4S), etc.—instead of 10.8 V(3S), 14.4V (4S) etc.
