  • Restart the 'BalanceBMS' app and try reconnecting.
  • Ensure your device is within close proximity to the BMS.
• Incorrect Readings in App:
  • Double-check all cell voltage sensing wires for correct order and secure connections. A multimeter can be used to verify individual cell voltages.
  • Ensure the app is configured for the correct number of series cells (S-count).

5.2 Protection Triggers

If the BMS enters a protection state (e.g., no output, no charge), identify the cause:

• Overcharge/Over-discharge Protection: The BMS will cut off charging/discharging if cell voltages exceed or fall below set thresholds. Check charger voltage and battery health.
• Ашыкча ток коргоо: Occurs if the load draws too much current. Reduce the load or ensure the BMS current rating matches your application.
• Кыска туташуулардан коргоо: The BMS will immediately cut off output in case of a short circuit. Identify and remove the short.
• Жогорку температура коргоо: If the BMS or battery temperature exceeds safe limits, the BMS will shut down. Ensure adequate ventilation and cooling.

5.3 Шайкештик жөнүндө эскертүү

Эскертүү: Using a BMS with an incompatible battery type or cell count can lead to severe damage to both the battery and the BMS, potentially causing fire or explosion. Always ensure your BMS matches your battery pack's specifications (e.g., Li-ion, LiFePO4, LTO, and S-count).
