Re: Does the Starting battery also need to be wired behind the Victron BMV-602S shunt

Only voltage is measured for battery 2. Usually battery 2 is a starting battery and as such is seldom down more than 1 or 2 AH.

Shunts are available separately from many sources, Blue Seas for one. The one supplied with the Victron is unique though as it has built in electronics and is designed to only connect with the Victron head unit.

Why do you want a shunt by itself?

If you want to measure anything other than VOLTAGE, on the second bank, then you'll need a second complete battery monitor. You can not add a second shunt to the Victron battery monitors. They read current and count Ah's for one bank only..

Re: Does the Starting battery also need to be wired behind the Victron BMV-602S shunt

Thanks for confirming Maine Sail and mitiempo,

I suspected as much, all making sense now. I have a 3-battery bank (two house, one starter), so need to monitor two batteries. On top of that, they are not identical.....
I'm interested in the shunt because I'm building my own battery monitors to communicate with the other parts of my system (and I need bigger displays too). There are plenty of shunt resistors available, but few are rated/tested in a marine environment, so this one seems fit for purpose.

Does the Victron shunt really have built-in electronics? Looks like just a few passive components/connectors on the circuit board (unless there are SMD's on the bottom side where it could get hot). If yes it could be interesting to decode the signal which may save some re-inventing of the wheel.
