12V LiFePO4 Battery BMS 4S 50A

12V LiFePO4 Battery BMS 4S 50A

Standard Type
Model : JLB-B12A1
  • Optimized Charging: Ensures that each cell within the battery pack is charged to the appropriate voltage, preventing overcharging and extending battery life.
  • Balancing: Monitors and balances the state of charge of individual cells, preventing over-discharging of any single cell, which can damage the battery.
  • Overcurrent Protection: Provides overcurrent protection, safeguarding the battery and connected devices from excessive current draw or short circuits.
  • Overvoltage Protection: Guards against overvoltage situations that can occur during charging or use, protecting the battery and connected equipment.
  • Thermal Management: Monitors and controls the battery’s temperature, preventing overheating and thermal runaway, which is critical for safety.
  • Capacity Tracking: Keeps track of the battery’s capacity over time, helping users understand how the battery’s performance changes with use and age.
  • Cell Voltage Monitoring: Continuously monitors the voltage of each cell in the battery pack, ensuring uniform charging and discharging for balanced performance.
  • State-of-Charge (SOC) Estimation: Provides accurate SOC estimates, giving users a clear idea of how much energy is left in the battery.
  • Communication: Some advanced BMS units offer communication interfaces (e.g., CAN, Bluetooth) for remote monitoring and control of the battery.
  • Safety Compliance: Helps batteries meet safety and regulatory standards, ensuring safe operation in various applications, from electric vehicles to renewable energy systems.
