Americas Splitting the batteries

[TJ D]

Hello, I may be missing a prior discussion, but has anyone split the dual batteries into a 'house' and 'start' battery? This is ubiquitous on boats, the start battery isn't used for domestic load so you don't end up stranded if you leave the lights on for too long. Curious if it's been done by anyone.

It would just require you to wire your added accessories to the aux battery; unless you wanted to get rid of the trickle charge back to the main battery, in which case you'd just have to replace the isolator with something else (such as the Blue Sea ML-ACR)

Yes, thanks. I'm just wondering how much opening of panels and other general surgery will be required, or if everything's at the batteries. I'll have mine on Tuesday, so I'll get to go digging then. Yay.

Everything is at the batteries (well, between them)

I plan on adding a second battery to my Quartermaster when it arrives in a few weeks. 9 Tubes on here has split his system (search for his build), and transferred many of the heavy load items to the second isolated battery. As they come from factory, all accessories are located on a fuse panel off the main starter battery. This is why I ordered a single battery, and then will "build" my system to what I require.

BUSBARS
The main power is distributed through the busbars. This post shows both busbars on an AU Spec Diesel model (there are some differences in the US model). The link has pictures and detailed descriptions, so you can use it as a starting point.
