Running 12V fridge/etc

[MaxJr]

If the fridge lives in the vehicle full time from experience the 500-720wh (specifically the EcoFlow River Pro that can charge up to 940 watts) is the sweet spot unless you live somewhere cold.

The small power stations cannot handle 24hrs in the Southwest. Unless driven daily/fully charged in the afternoon.

The problem with a LFP swap, is unless you have one specifically made for replacing a starter battery like the very expensive Dakota it won’t provide enough voltage to fully charge the LFP.

With the available space you’d still have less capacity than a standalone unit.

You can add a low voltage cutoff before the fridge and dial in the voltage.

I'm confused. Do you have a 250? The starting battery isn't relevant.

It was made relevant through a discussion on the preceding pages for want of an unswitched source.

I had one, gave it away to a relative because 256wh is not enough for the Southwest USA unless you have solar, or fully charge it in the afternoon for overnight.

I would arrive home at 5-6pm with a 250wh fully charged station and it would be under 20% by when I drive it again in the morning in the summer. I really wanted it to work because it’s tiny.

The confusion may lie in my inability to properly multi quote several posts.

I'm really interested in what people come up with to use the hybrid (traction) battery, but frankly it's pretty darn small (150Ah @12v) as most folks have called out. It's small enough that I wonder why the whole floor of the land cruiser is raised as much as it is. That's the same rise more or less that the folding seats fit into in the GX460. For context, here's a 288v 6.5Ah battery: check out the dimensions, ~18x15x4inches thick, seems like you could fit 2 of those in that real estate. Does the LC250 have crazy uptravel or something else they've made room for?

Traveling throughout Baja with 200Ah of Lithium, having a fridge / freezer and cooking with induction was awesome, but required the solar panel I had on my roof, and I had it set up where I could plug in additional solar to my bumper, for a total of ~500w. If you're in the desert, it takes a lot of energy to keep things cool / frozen, especially if you're trying to get away without using any other fuels for cooking.

I was kinda hoping to not need to try and hide those batteries again in the interior of the vehicle. I didn't want to have any additional power units to load up or take up interior space, and I wanted it all seamless, no switches (i did have cutoffs and voltage sensitive isolators), nothing to remember, like what I built for my GX. I didn't have to touch it once for nearly four years, and had an outlet from my inverter into the bumper as well, so as long as whatever power I needed remained within the length of my extension cables, I was good to go.

Just saw a video on where the 12v battery is and how much room there is in there... Looks like you could fit something taller in there, if the cranking amps come from the traction battery, seems like you could put a larger 12v lithium in there, with a load isolator to make sure you can always have the voltage required to wake up the traction battery... Thanks for all the info, learning a lot about the new LC250!

You gave away your vehicle to a relative? He’s asking whether you have a 250 series Land Cruiser…
