3S BMS for 18650 Battery Output 11.1V 40A

Description:
The 3S BMS for 18650 Battery is designed for managing three 18650 lithium-ion cells in a series configuration, providing a nominal voltage of 11.1V (3.7V per cell) and capable of handling up to 40A continuous discharge current. This BMS ensures safe operation of the battery pack by monitoring parameters like voltage, current, and temperature. It features overcharge, overdischarge, overcurrent, and short circuit protection, making it ideal for high-power applications such as electric vehicles, power banks, RC vehicles, and solar energy storage systems.

Specifications:

Key Features:

• Cell Balancing: Ensures that all cells in the series configuration are balanced, ensuring even discharge and extending battery life.
• High Current Capacity: Supports a continuous discharge of 40A, suitable for applications that require higher power output.
• Overcharge & Overdischarge Protection: Protects the cells from damage due to overcharging (more than 4.2V per cell) and overdischarge (below 3.0V per cell).
• Short Circuit & Overcurrent Protection: Protects the system from short circuits and excessive current (above 40A) that can cause damage.
• Temperature Protection: Prevents overheating by cutting off power if the module exceeds a safe operating temperature.
• Compact Design: Easy to integrate into DIY projects, offering excellent protection in a small form factor.
