Hi folks,
Getting reading to deploy a fair bit of Victron gear to our boat, replacing the aging power system. This will include two BMV712 Smart Shunts on our two main starting batteries - at start up, each battery draws approx 660Amps, to cater for that I've also purchased two of the 1000A shunts.
I know there are arguments around the worth of measuring starter batteries, but we have other loads (bow thrusters) and some house services running off them so want to capture it all.
I now want to confirm the right cable to size it for. I can't easily get to the boat to measure the existing cable, but I would guess around 20mm diameter, thick cables indeed.
So I thought I'd try and calculate out what I need in advance. I've tried the Victron Cable calculator, but that maxes out at 400 amps. And I also assume that it would be measuring 1000a constant use, where I'm looking at surge (starting) and certainly less than 100amps when normally running.
Shunts will be mounted right next to batteries, so no longer that 0.5M, probably closer to 0.3M so very short runs.
I'm thinking 000 B&S at this stage?
Thoughts?
