3S 60A 12.6V Li-ion Battery Protection Board BMS with Balance/Equalizer

The 3S 60A 12.6V Li-ion Battery Protection Board (BMS) with Balance is a high-performance battery management system designed to protect and optimize 3-cell series lithium-ion or 18650 battery packs. Featuring a massive 60A continuous discharge rating, this board is engineered to handle high-current loads while ensuring the safety of your battery cells. The integrated active balancing circuit ensures each cell is charged uniformly, maximizing the overall lifespan and capacity of your custom battery pack.

This BMS is highly popular among makers and engineers for high-torque applications such as starting electric drills, powering RC vehicles, driving high-power DC motors, and building DIY 12V portable power banks. It is fully compatible with standard 3.7V nominal (4.2V fully charged) lithium cells, including 18650 and 21700 form factors. With its robust multi-MOSFET design and low internal resistance, it provides stable power delivery and excellent thermal performance under heavy loads.

Features:

• High Current Capability: Supports up to 60A continuous discharge current, making it perfect for high-power motor startups and power tools.
• Integrated Cell Balancing: Features onboard balance resistors to equalize cell voltages during charging, preventing individual cell overcharging.
• Comprehensive Protection: Provides robust protection against overcharge, over-discharge, over-current, and short-circuits.
• Electric Drill Compatible: Specially optimized to handle the high transient startup currents of electric drills and heavy-duty DC motors.
• Low Heat Generation: Utilizes multiple low-RDS(on) MOSFETs and a thick copper PCB layout to minimize power loss and heat buildup.

Package Includes:

1 x 3S 60A 12.6V Li-ion Battery Protection Board with Balance
