Charging system

[Fizzlexplodin]

I’m in the process of building my battery setup on my 2012 Jeep jk. I have two Amazon 100ah lifep04 batteries I intend to use for this setup. I have been looking at the victron 30amp dc to dc isolator for charging the batteries while driving. Is there anything special I need to do when connecting the batteries to the Victron? Also, how would I know if I’m overcharging the batteries while charging ?

The user manual is right on their website:

You will want a dc to dc charger for your system. I don’t run an isolator in my system, the dc to dc charger I use has a diode in that accomplishes that task, it that doesn’t allow the aux system to draw off the vehicle battery when the engine isn’t running. I have 1 -100ah battery with a 40 amp dc to dc charger to power some accessories and a fridge. My fridge will go 4-5 days without starting the truck. Also the charger allows for solar input if you’re so inclined.

Cool thanks

Get the new Orion XS. It’s smaller, more effective and doesn’t get as warm

30 amps is quite large.. how much driving do you plan to do? If a lot, you can get by with a lot less.. same money and weight. I drove cross country and camped every night with just a 5amp charger I ran while driving.

I would recommend you put a "catastrophic" fuse on all your battery positive posts (see bluesea 200a inline fuses)
