6000mAh 3.7V Li-ion Battery Pack | 2-Pin Connector

Massive 6000mAh Capacity for Extended Runtime This QSUG lithium-ion battery pack delivers an impressive 6000mAh (22.2Wh) of capacity, ensuring your portable projects run significantly longer between charges. Whether you are building a remote environmental sensor node, a custom Bluetooth speaker, or upgrading the battery life of an RC vehicle, this high-density cell provides the sustained 3.7V power required for power-hungry applications. Its compact 6.6cm x 3.6cm x 1.9cm dimensions make it easy to conceal within custom 3D-printed enclosures or tight chassis spaces. Standard 2-Pin Connector for Easy Integration Equipped with a pre-attached 2-pin connector, this battery pack eliminates the need for dangerous direct-cell soldering. The universally recognized red (positive) and black (negative) wiring ensures you can quickly and safely connect the battery to your development boards, motor drivers, or dedicated charging modules. The secure clip-in design of the 2-pin plug prevents accidental disconnections caused by vibrations in moving robotics or RC models. Pro Tip from Our Technicians Always use a dedicated 3.7V/4.2V Lithium-ion battery charging module (such as the TP4056) to safely recharge this battery pack. Our Sham Shui Po DIY electronics specialists strongly warn against connecting this battery directly to a 5V USB power supply without a proper charging circuit, as exceeding the strict 4.2V charging limit will cause the battery to swell, permanently damaging the cells and creating a severe fire hazard.
