House battery - Where are you pulling power for DC-DC charger

[Levi]

Hi All,

In short, factory dual battery system is problematic. So I am leaving as factory for a simple dual crank set up (not using EXT at all) and installing an independent house battery (LiPo) with a DC-DC charger (smart alternator ready 3 wire) includes MPPT input. The new system will sit in my canopy, not the cabin (Quartermaster) with alternator charge supply coming from rear seat, via factory rubber boot exit.

I am curious, for anyone else adding a DC-DC charger, where are you drawing the input from?

I’ve got a good mate who’s well versed in this stuff who’s going to educate me on wiring, but like to know ahead where others have connected in.


Cheers,
Levi

I have thought of adding a house battery at some point and I was considering using the spare 40amp fused cable, in my battery box that has an ignition trigger wire. This is fed from fuse Fl13.
I have the dual battery and high amp wiring set up.
I haven’t researched this any farther to see if it’s feasible. If it isn’t I figure I could still use the trigger wire if needed and connect fused power directly to the starter battery or spare fuse point in fuse block next to battery, to power the dc to dc charger.
