I have just ordered the BMV 712
Can someone please advise what size cable I should use for the connection between the battery and the shunt ?
Normally you simply use the same size cable as used for the main battery wiring.
In general it should be as thick & short as practical to provide the most accurate BMV reading (ie. somewhere around 35 to 70mm² / 2AWG to 0/2AWG is normal)
Thankyou for your help.
Additional resources still need to be added for this topic
