Other 12V Sources with a 24V-12V converter
Switching to a 24V battery bank has gone well so far. The 40A Victron 24V-12V converter seems to handle all my 12V loads without issue. It keeps the V at about 13.2V But a question: there can some...

I am assuming you will using two 12V batteries in series to get to the 24V you need...
You should be able to tap off of the jumper cable between the two 12V batteries in series to get your 12V needs for the break away switch and probably your jack raise 12VDC etc... These are not permanent drains and are controlled by switch actions...
There may be however a unbalance situation taping in the center and drawing DC current from only one 12VDC battery more than the other battery. These actions always seem to pick on the better battery and draws it down the worse battery in the series loop... In other words using one of the batteries more than the other one probably doesn't get to the state of charge point at the same time which eventually brings it down in performance to equal out the DC current path when using using the 24V system. I have done this on a coupe of those ARMY 24VDC systems for 10KW Power Gen Sets requiring 24VDC Start Motor circuits.
