I have a Victron BMV-712 battery monitor. It comes with 10m of RJ12 cable to connect the shunt to the display. The shunt is only 1m away from the display so I have 9m of cable to bundle up into the battery compartment. If I buy a replacement cable say 2m long off Amazon, is it likely that the replacement will be wired up differently and not work, or are these bog standard?
