I have a 12V 2 batteries in parallel system with two revolution power lithium 60Ah batteries with 1m of 2B&S cable running from the positive to a circuit breaker then load. The Victron shunt probe (Supply cable) is connected to the line side of the circuit breaker (I.e. always on and before any load). All load, charger and earth are connected to the correct side of the shunt with only both batteries connected to the other side.
All load components are working normally and voltage is as expected around 13V however my Victron BMV712 is only reading 7V and says that there is an idle draw of over 700A, This is definitely false.
I've tried factory reset and linking to my phone to update firmware, the errors persist.
Any Ideas what's going on or if I've done anything wrong? is the unit just faulty?
