What should I do if I notice smoke or a burning smell when connecting the voltage-sensing harness?

Immediately unplug the harness. Check if cell wiring follows the correct B0→B1→B2→... sequence with no skips or cold solder joints. For multi-interface BMS boards, always connect low-position first, then high-position. Inspect for exposed wire shorts or solder beads on the board.

Battery pack does not discharge — what to check?

First, check if an external switch is configured and try pressing it. Connect Bluetooth or PC software to verify discharge MOS status: "1" = allowed, "0" = blocked. If in sleep mode, this is normal — wake with switch, charge, or discharge. If the LED flashes at 200ms, a fault protection is active — check voltage, current, or temperature alerts via the app.

Why does the voltage-sensing harness become warm during operation?

The most common cause is incorrect wiring sequence — high/low positions are reversed. Also verify the harness string count matches the BMS factory settings. Incorrect matching causes heating and can damage internal circuits.

One cell voltage drifts significantly under load — how to resolve?

Check solder connections on the affected cell and its adjacent cells. Verify the voltage sense wire is firmly soldered. Use soft copper bus bars for inter-cell connections — power cables have higher resistance and cause imbalance.

Why does the load disconnect unexpectedly?

Three potential causes: 1) Battery voltage dropped below the over-discharge threshold; 2) Load/inverter power exceeded over-current limits; 3) Device has large capacitors that triggered short-circuit protection. Connect to PC software or Bluetooth app to read the active fault code.

Power cuts out during rapid ascent — what should I check?

Check for over-current protection triggering under high load — adjust protection parameters via PC software. Verify sufficient remaining charge (low-voltage protection may be active). Inspect all power cable solder joints for cold or loose connections.
