A 2S 20A Balance Battery Management System (BMS) is designed to manage and protect 2-cell lithium-ion or lithium-polymer battery packs. It ensures safe operation by regulating charging, discharging, and balancing the voltage across cells.

Key Features:

• Overcharge Protection: Prevents excessive voltage that could damage battery cells.

• Over-discharge Protection: Stops the battery from draining too deeply, preserving lifespan.

• Overcurrent & Short Circuit Protection: Limits excessive current draw and prevents electrical faults.

• Balancing Function: Ensures both cells in the 2S pack charge evenly, optimizing performance.

• Compact & Efficient Design: Small form factor for easy integration into IoT, robotics, and EV applications.

• Wide Compatibility: Works with 18650, 26650, and polymer lithium batteries.

This BMS is commonly used in RC models, DIY electronics, power banks, and electric bikes, ensuring safe and efficient battery operation
