Help please! I have a problem with my Lynx Smart BMS in my sailboat.
The setup is: Multiplus II, Lynx Smart BMS, Smart Battery Protect 200 (for loads), Lynx Distributors, Victron Lithium Battery Smart 200ah x 5 in parallel, Cerbo GX with Touch 50, and Orion Tr Smart 12-30.
The Lynx Smart BMS sometimes shuts down in full (bluetooth stays on), leaving the boat with no power at all. It doesn’t send or logs any pre- alarms or warning. It simply opens the contactor and shuts itself off except bluetooh. Batteries are fully charged, all cells balanced and normal temperature. This has happens about an hour or so after turning the Multiplus off with only about 20amps of loads.
How can this happen with no alarms or warnings? As understand, any low voltage would trigger/close the ATD and force the battery protect to open. Even if that would fail, the Lynx BMS is supposed to trigger a pre-alarm. But voltage is fine and no alarms.
