Camper setup is 2x life battery, smart shunt, cerbo, mppt, BMS 701, multiplus.
Found notification No Comms between BMS and multiplus.
One battery disappeared on Bluetooth. 13v on multimeter.
Multi loads disconnected, low v led, no charging while on mains. 2x battery BMS connected via daisy chain.
Other battery low alarm, not charging via mains. But charge off engine ok. Now approx 13v.
Checked all connections, has been stationary no vibration issues.
Recent cerbo update was fine before.
Any help good people?
