Nothing real exciting, but a little more progress. Made up the first battery cable, big thanks to a local guy for letting me borrow his crimpers! They are sweet. Self adhesive shrink tube is awesome.
New cable let me install the shunt for the Victron battery meter. While I like the RJ45 connections for the meter, damn getting those heads fished through holes sucks!
Gotta install this end still... But it works!
