Smart BMS

Smart BMS 4-8S 12V LiFePO4 100A 200A

Smart BMS supports BT communication function with mobile APP (Android/IOS). You can check battery status in real time through APP, set protection board working parameters, and control charge or discharge. It can accurately calculate remaining battery power and integrate based on current time.

When in storage mode, the BMS won’t consume the current of your battery pack. To prevent the BMS from wasting power for a long time and damaging the battery pack, it has an automatic shutdown voltage. When the cell falls below the voltage, the BMS will stop working and automatically shut down.

    Smart Energy Working Mode Switching

    • Storage Mode
      In transportation, storage, offline or wireless transmission off mode, the BMS is in storage mode, which does not consume battery pack current.
    • Normal Working Mode
      When the charger is inserted in the storage mode or off mode, the BMS will immediately return to the normal working mode, and all the protection functions, equalization functions and communication functions will return to normal working.
    • Shutdown Mode
      To prevent the BMS from wasting power for a long time and damaging the battery pack, the BMS has an automatic shutdown voltage, and the BMS automatically shuts down when a cell falls below the shutdown voltage.
    • Standby Mode
      When the battery pack is in the static state (no charge or discharge current and no equalization current), the BMS will automatically enter the standby state after the set time (1-30 days can be set) is exceeded.
