Offering essential protection and balance features, this BMS ensures safe, reliable, and efficient operation for a wide range of applications, from electric vehicles to energy storage systems. With a pre-installed connector for easy setup, the system provides convenience and peace of mind.

Key Features:

• 5S Configuration: Optimized for 5-series Li-ion battery packs, the BMS provides a nominal voltage of 18.5V and a fully charged voltage of 21V (4.2V per cell).

• 20A Maximum Discharge Current: Capable of handling up to 20A of continuous discharge current, making it ideal for mid-power applications like e-bikes, solar storage, and power tools.

• Integrated Connector: Pre-installed balance and power connectors for simplified wiring and quick installation, reducing the time and effort required during setup.

• Cell Balancing: Features active cell balancing to ensure uniform charging and discharging across all cells, improving the overall performance and lifespan of your battery pack.

• Overcharge & Overdischarge Protection: Automatically disconnects the battery from charging or discharging if voltage exceeds safe thresholds, preventing potential damage to cells.

• Overcurrent & Short Circuit Protection: Includes built-in overcurrent protection (up to 20A) and short circuit protection, ensuring safe operation under high-load conditions.

• Temperature Monitoring: Equipped with temperature sensors to monitor battery temperature during charging and discharging, offering added protection against overheating.

• Low Standby Power: Minimal power consumption in idle state, optimizing energy efficiency when the system is not actively in use.
