3S 60A 18650 Lithium Battery Protection Board (BMS) – 11.1V/12.6V High-Current Protection Module with Balance Charging for Inverters, Robotics, and High-Power Motors

Product Description

Power your high-demand electronics with the 3S 60A 18650 Lithium Battery Protection Board. This industrial-strength Battery Management System (BMS) is designed for applications that require massive current delivery, such as 12V inverters, high-torque robotic drives, and portable jump starters. At Robogears, we recommend this "Balanced Version" because it actively monitors each of the three cells, ensuring they charge and discharge uniformly. This prevents "cell drifting," where one battery becomes weaker than the others, thereby extending the cycle life of your entire 11.1V pack. Its heavy-duty copper traces and reinforced MOSFET array are built to handle a continuous 60A load, making it one of the most powerful 3S modules available for your Pimpri workshop projects.

Detailed Key Features

• Massive 60A Discharge Capacity: Specifically engineered to handle extreme current spikes, perfect for starting DC motors or powering small 12V DC-to-AC inverters.

• Precision Cell Balancing: Includes an on-board balancing circuit that shunts excess current from fuller cells to allow weaker ones to catch up, ensuring a 100% healthy pack.

• Triple-Layer Protection: Integrated hardware safeguards against over-voltage (4.25V per cell), under-voltage (2.5V per cell), and instantaneous short-circuiting.

• Low Heat Generation: Utilizes ultra-low $R_{DS(on)}$ MOSFETs to minimize energy loss and heat buildup during high-current operation.

• Universal 3S Compatibility: Works with all standard 3.7V/4.2V Lithium-ion and Lithium-polymer cells, including 18650, 21700, and flat lipo packs.

All Technical Details

• Start-up Pulse Support: Capable of handling momentary peak currents well above 60A for motor ignition.

• PCB Quality: Thick 2oz copper PCB ensures that high current does not lead to track delamination or excessive voltage drop.

• Temperature Resilience: Rated for operation from -40°C to +85°C.

• Applications: Battery-powered vacuum cleaners, 12V solar storage, DIY electric scooters, and high-power RC hobby vehicles.
