Volts zero to 12.99V upon vehicle charging

Any ideas as to what may have caused this:

Recently had my batteries go from 13.2 Volts to 0 Volts on the Magnum and Smart shunt over 2 days with no load. Batteries showed only 0.9 Volts after charging overnight with the Magnum.

Upon running the vehicle the system volts immeadiately jumped to 12.99 volts and systems worked and batteries will now charge.

Setup:

Rig: 2016 Liesure travel Van MB

Battleborn (2) 100Ah LiFePO4 Heated batteries

Magnum MM1212 Inverter Charger

Victron BMV-712 Smart Shunt
