Again if you lived closer this would be the perfect conversation to have sitting around a camp fire having a cocktail or three.

I could use one of these nights, too.

Cmon up

National Luna is the isolator that I used. It isolates but you can push a button to have both working together

 

[scrapdaddy]

Nice setup Gordobe!

 

[Megadoomer]

If yall are going remote on your batteries, please put a fusible link at both ends of the wire.

 

[RUSH55]

A tragic story behind that advice, Doomey?

 

[Megadoomer]

Not for me, just preempting tragedy. The idea is that if you have a fault on the opposite end of your wire you now have 20 feet of cable with a load before it gets to your fuse. Nobody need s a crispy piggy.

Awesome setup.. any photos of it mounted on the chassis?

Just for size comparison I snapped a few photos for you. This single four cell battery has a little over the capability of two of the optima batteries combined.

I agree with Bob, a good solution to a problem.

Appreciate the details, esp the call-out on the cow s***, I was wondering what that was...

 

[PabloCruise]

I may be mistaken, or I may have over looked this detail already covered, but am I correct that you don’t want to different chemistry batteries charging in parallel?
Or, would these 2 different batteries need to be isolated when charging?

Yes and no sort of.

Yes the batteries would need to be isolated no different than most systems that have a “house” and “start” battery. The main difference would be the DC to DC charger in line on the Lipo side, no different than charging your cell phone when driving.





If you spend some time poking around the internets looking at (van life) or (schooly life) you can check out some of the high end builds that run this system. Most use solar to charge when parked off grid and alternator charging only when driving.

Mostly solar chat but lots of info about charging with vehicle alternator here too. Vehicle Mounted Systems

Found this old thread and had a question. Has anyone installed a second battery on the flat plate on the driveside just in front of the aircleaner intake. If so, got any pictures and advice? The old plowpig55 needs some more juice. Thanks!
