6S-10A JLGW Li-ion Battery Management System (BMS)

Overview:

The 6S-10A JLGW Li-ion Battery Management System (BMS) is a compact and reliable solution for managing 6-series lithium-ion battery packs. Designed for moderate power applications, this BMS provides essential protection, balancing, and monitoring features to enhance the performance and safety of your battery system. With a maximum discharge current of 10A, it is perfect for energy storage, e-bikes, and other portable devices that require consistent power management.

Key Features:

• 6S Configuration: Designed for 6-cell series lithium-ion batteries, the BMS operates with a nominal voltage of 22.2V and a fully charged voltage of 25.2V (4.2V per cell).

• 10A Maximum Discharge Current: Supports up to 10A of continuous discharge current, making it ideal for moderate power loads such as energy storage and lightweight electric vehicles.

• Active Cell Balancing: Ensures that all cells in the battery pack charge and discharge evenly, preventing imbalance and optimizing the lifespan of the pack.

• Overcharge & Overdischarge Protection: Automatically disconnects the battery from the charger or load when voltage thresholds are exceeded, safeguarding the cells from damage.

• Overcurrent & Short Circuit Protection: Includes real-time overcurrent protection (up to 10A) and short circuit protection, ensuring your battery operates safely under load.

• Temperature Monitoring: Monitors the battery temperature during operation and cuts off charging or discharging if the temperature exceeds safe limits, preventing overheating.

• Low Standby Power Consumption: Designed to minimize energy loss, the system draws very little current when idle, improving energy efficiency.
