9.3.6. How to test if the BMS is functional
To test if the BMS is functional, disconnect one of the BMS cables and see if the BMS will go into alarm mode.
BMS
Check BMS functionality by deliberately loosening a BMS cable
9.3.7. System in sleep or hibernate mode
This is indicated by the status LED off and the Bluetooth LED flashing every 3 seconds.
The Lynx Smart BMS goes into sleep or hibernation mode once the battery or a battery cell has been deeply discharged. The
Lynx Smart BMS will conserve as much power as possible, to not discharge the battery much further. Bluetooth is still active, but
other non-essential circuits are turned off, including the power to the Lynx Distributor(s).
Check the 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 re-activate and close its contactor to allow for battery charging.
9.3.8. Battery communication error
This is indicated by the red LED flashing 2 times every 4 seconds or with the GX device BMS cable error. A battery
communication error occurs when the Lynx Smart BMS is not connected to the battery BMS communication cables, or if there is
an issue with the BMS cables. To remedy this error, check the following:
• Check if both battery cables are connected to the Lynx Smart BMS.
• In case of a multiple battery setup , check if all batteries are interconnected
• Check for loose connections, the male connector needs to screw “hand tight” into the female connector.
9.4. Battery monitor issues
9.4.1. Incomplete current reading
The negatives of all the loads and the charge sources in the system must be connected to the system minus side of the Lynx
Smart BMS.
If the negative of a load or a charge source is connected directly to the negative battery terminal or the “battery minus” side on the
Lynx Smart BMS, their current will not flow through the battery monitor and will be excluded from the overall current reading and
the state of charge reading.
The SmartShunt will display a higher state of charge than the actual state of charge of the battery.
