High Discharge Rate 6S3P 22.2V 6Ah 18650 Lithium Battery Pack for Grinders
Industrial-grade power tools such as grinders and drills require more than just consistent power—they need instant burst current, physical durability, and unwavering stability under the most demanding conditions. When a leading tool manufacturer faced issues of battery overheating and insufficient startup current, they turned to CMB for a solution.
We responded with a purpose-built 6S3P 22.2V battery pack, engineered with 15C/30C high-rate industrial cells and an advanced smart protection system. This combination delivers the peak power needed for motor startup and heavy-load operation, while maintaining thermal safety and runtime consistency—even during prolonged use.
Key features：
- 15C/30C-rated cells provide instant current for startup and acceleration
- 6S3P configuration provides 6000mAh capacity
- Dimension: 110 × 56 × 70 mm
- Integrated smart BMS for real-time temperature, current, and voltage monitoring
- Equipped with a spark-resistant XT60 connector
- Ideal for high-drain power tools including grinders, drills, and various industrial-grade equipment.
