Testing a Lynx Smart BMS by connecting a single BMS extension cable to both BMS cable connections
Multiple batteries and BMS check:
• Bypass one of the batteries by disconnecting both its BMS cables.
• Connect the BMS cables of the neighbouring batteries (or battery and BMS) to each other, effectively bypassing the battery.
• Check if the BMS has cleared its alarm.
• If the alarm has not been cleared, repeat this for the next battery.
• If the alarm is still active after all batteries have been bypassed, the BMS is faulty.
• If the BMS cleared its alarm when a particular battery was bypassed, that particular battery is faulty.

8.4.5. How to test if the BMS is functional
To test if the BMS is functional, disconnect one of the battery BMS cables and see if the BMS will go into alarm mode.

8.4.6. System in OFF mode
This is indicated by the status LED off and the Bluetooth LED flashing every 3 seconds.
The Lynx Smart BMS goes into OFF mode once a low cell voltage event occurred and no charge voltage has been detected for 2
hours to conserve as much power as possible. Bluetooth is still active, but other non-essential interfaces are turned off, including
the power to the Lynx Distributor(s).
Check the cell voltages of the connected batteries and if they are low, charge the batteries. As soon as the Lynx Smart BMS sees
a charge voltage, it will automatically reactivate and close its contactor to allow for battery charging.
