Lithium Battery Mounting Suggestions for the Bed

[Blitzinger]

I have an RSI smartcap. I ordered the bin and a red arc system as we have a massive 75q fridge that we don’t want to keep taking in and out and want to keep it powered on all the time.

I haven’t decided if I’m going to do a 230aH or 280aH lithium battery but I want to see if anyone has mounted one to their bed before and if there’s any case or mount they used.

Couldn’t find one I liked, so I built one. Group 31

Looks good! May have to order some stuff from 80/20 if I can't find it

Use bosch strut knockoffs.

Is that all mounted to a bin?

No, to a Catapult floor system. I will go out and take a current picture so you can see it clearer.

Here it is today. Still waiting for the cover to be fabbed up.

Thanks! That's an idea but it would have to sit a bit higher to clear the bed slide

Yes, I'm going the opposite, I put the floor system in first, and then once the cover is in, then I will add the slides.

Mine is similar. but with the inverter in a different location and not using the lynx system. It sits behind the wheel well so if the fridge wasn't bolted in and you needed to slide a big box in between the wheels the electrical wouldn't be compromised.

Can you take a pic from a few feet back and of the battery too?

Yeah I'll get you some pics tomorrow afternoon.

That's a nice setup. I was considering a similar setup, but after talking with KP at Zero Declination, I went with his suggestion to mount to the back wall.

Here you go. My batteries are AGM. But my system design can utilize AGM with a DC/DC charger, AGM directly connected to the starting battery via smart solenoid, or dual lithium batteries. Currently I have 2 115ah FR DC batteries side by side. It also includes a solar controller and a shore power tender/charger than can also be switched into 'power supply' mode if your at a campground with power.

it sits probably an inch behind the wheel well. I am debating making a cover or not. A cover would keep the sun off of things but would also keep heat in and these components do make some heat.

The bottom switch is for the two AGM batteries so that I can have one, two, or both connected in case one needs to be removed or for troubleshooting. The top switch is routing power to the Switch Pros system. So power can come from either #1 which is the starting battery, #2 which is fed by the switch below, both, or none. In the picture above, the bottom 3 terminal fuse block is for the main starting battery to feed to the DC/DC and run the compressor. The 3 terminal block above it is for the switch pros system, inverter, and input from all 3 charging options.

I am currently using dual 115ah Full River DC series batteries. My location is not conducive to lithium and these batteries can be run to 30% SOC / 70% DOD which is more than sufficient. With the way my system is built I can easily run lithium or AGM with no modifications needed, only adjusting via phone ap the charging profiles of the victron components. The batteries sit in front of DUAL 13 gal water tanks and I oriented the batteries side by side for even weight distribution. The water tanks dictate my setup is not conducive to putting on the back wall. I am somewhat contemplating relocating the batteries in the cab under the rear seat delete but that will be a winter project if it happens.
