18650 Battery Pack | 7.4V 6000mAh 18650 Rechargeable Battery CC CV with Female DC Barrel Jack Connector for Power Output Made in China
The model battery shows a compact, enclosed 18650 lithium-ion battery pack, wrapped in durable black heat-shrink tubing. It features a female DC barrel jack connector for power output/charging, making it ideal for portable and low-to-medium power applications.
Construction: It’s built from multiple 18650 lithium-ion cells arranged in a small, block-style configuration, most commonly 2S (7.4V) or 3S (11.1V/12V). The black heat-shrink wrap provides excellent insulation, impact resistance, and water resistance for everyday use.
Connector: The pre-attached female DC barrel jack is a universal, widely used connector, allowing direct plug-and-play connection to chargers and devices without soldering.
Protection: Integrated with a Battery Management System (BMS) to safeguard against overcharging, over-discharging, short circuits, and overheating, ensuring safety and extending the battery’s cycle life.
Common Applications: Perfect for powering LED bicycle lights, solar garden lights, portable fans, small speakers, surveillance cameras, and DIY electronics projects that need a reliable, rechargeable power source.
