These are the types of videos that have people wigging out over what I've been able to do with the Jeep. Simple, clean, and to the point. Thanks!

People like you don't need to do this but people like me are truly thankful.

Finally , a vid that makes a project we can understand for the average man or woman . Cool beans . Awesome .

Thanks for this! All these videos on KZfaq around dual battery systems seem so daunting for people without that much automotive electrical experience. This was just what I needed thanks!! 🤘🏽

You made this dual battery setup easy for a beginner like me. Appreciate you sharing this DIY setup!

It's definitely the best tutorial with dual battery setup that I've watched on YT. I've watched a ton and yours takes the cake ! Thanks for sharing.

Very clean straightforward install looks great

Thank you for making this video for some of us dummies. Now I feel so much better doing this for my little 4x8 teardrop I got.

My goodness I finally found a straightforward and simple settup... nice truck by the way !

Thank you. You explained everything better than any others I've seen. It's appreciated! Thanks for taking the time to do this post.

Thank you, very comprehensive and easy to understand. 👍

I was looking to install an roof ac unit on my truck canopy and this finally simplified it where I feel comfortable doing it myself now 🎉

Excellent video , I've acheived 2 similar setups in both my personal & work utility truck , it's essentially awesome for both a working environment and a semi off-grid personal Lifestyle.

nice project 👍. thank you for the info. i didn't know about the battery disconnect option. nice!

Thanks for sharing. I really like how simple your setup is.

The shelf idea is Genius, Smart man👍

Best instructional video on this project. 👌🏿

You just solved my problem brother. Thanks a million man. Sweet build too

Super simple video. All these other overland videos take this explanation to a whole new level

Hey great video man. Everything I needed to know and a great example of how to get it

That's a neat clean setup you have there. I liked that you used good quality welding wire for the battery to inverter connection. Those cables that come with inverters should never be used. You nailed it when you said they are junk.

Simple and works! Two things I like....

Amazing explanation. Thank you very much. I will hopefully be able to use this info to install a secondary battery on my 2021 RAV4 Prime.

One the best and simple. Exactly what I was looking for.

Thanks for the excellent video, hopefully doing this to my truck whenever i purchase a topper.

Good Stuff, Great Tips👍🏿

Excellently explained… if that’s a word lol, I’ve watched dozens of hours of videos trying to figure it out and you finally got me there. I have a 1988 Toyota pickup that I’ve been wanting to do this to. Finally found what I’m looking for. Great video

The way like the way you explain everything Thank you

This! Is! The! Video! I! NEEDED! THANK! YOU!

Excellent video! Thanks

Im an electrician an this is a great tutorial great video.

Great job. Keep it simple. I picked up 2 large used batteries from the auto repair shop in my neighborhood. Free. I'm running a 1500 watt inverter. I run a ton of stuff. 2 ham radios, lights for the tent. 1 CB radio. Winch. It's all in the back of my expedition. I mounted the solar panel on the top. You don't even know it's there. Fun project. Remember! When in doubt use bigger wire. If it says 16 wire use 14 and so on. I also keep 2 fire extinguishers in my rig. I liked your comment. When in doubt go big on wire. There is a formula for wire size. I'm not that smart. I just go big. Why take a chance? Have fun.

Great video..... 👍 Easy to understand, thanks 👍

Thank you for the easiest way of installing an auxiliary battery

Thanks so much for posting this! Been wondering how I would install a second battery in my pick-up truck on a do-it-yourself basis for a very long time...!

Just got my isolator kit. Battery next and I'm ready to do this in my Express Van. Thanks!

Awesome video all the exact information I needed 👍👍

Beautiful clean setup!

Very informative and will attempt to a secondary battery system to my 08 Ford F-250.

Great set up 👍👍👍👍

Great simple video

Great vid. Thanks!

Nice work. You should coat your frame with chainsaw oil. It creates a protection layer between frame and road salt,etc. i put it on my wifes truck two years ago. it works. It dries out , just paint it on or wipe it on with throw away rag. Your off grid rig will last twice as long..

Great ideas. Thanks

You should install a fuse on the wire between the truck battery and the isolator under the hood. If you develop a fault on that wire there is nothing to protect your truck battery.

Wow. Great video. Best one I have seen.

I. Have done a couple of similar systems, but I also have solar power. I use the system to charge up a trolling battery I use on the electric motors only lakes I fish. It’s lithium so I top it up each day. It takes about 1.5 - 2 amps from the battery hooked up to the inverter to put one amp back into the trolling motor battery. Not too efficient, but the solar makes it basically free. I have a 240 ah LiFePO4 battery in the Rayzr truck camper I have and it’s amazing, expensive, but can run the 3000 watt inverter and run the camper itself. I bypassed the converter, otherwise you are likely gonna have issues. I have a small trailer I have a 2 battery system in. 2x 100 ah LiFePO4 batteries and a 1500 watt inverter. 1500 watts is a lot in itself!! You have a nice simple system. Using the box like you do, those Bedrugs are excellent and tough!!! Thanks for sharing!!! This one goes into the saved file.

Great video

great video

Great Job

awesome video

Thank you for the video! JUST FYI I would run wiring along the frame and not the body of the truck. incase service ever removes the cab to work on the engine.

very well explained

Good video, I can do my hook up, now. Thanks.

Great 👍🏾

Very nice.

Nice video. I have basically the exact same setup in my travel trailer, but I have the isolator (same unit) and the battery and inverter in the trailer. I installed mine to run my fridge while on the road. The problem I'm having is that the isolator is cycling on/off every 15 seconds, because whenever it connects the two batteries, the voltage between the truck and house battery gets "averaged" so both are below the 12.9V cutout, so the isolator disconnects. As soon as they disconnect, the the truck battery voltage pops above 13.3 and it re-connects, and it cycles indefinitely. The alternator is plenty big, and the camper/fridge is only drawing about 15 amps when the batteries are connected, so it's not a heavy load. The camper battery powers the fridge for about 4 hours on its own, but I'd like to have the power from the truck helping to keep the deep cycle camper battery charged, which it should be able to do with little problem. I appreciate any tips; it seems like you'd have the same problem I did.

Gonna try to do the same thing w my work truck

Excellent

Gracias amigo. I'm a 'show men's guy. So yeah!

Good video but you should put breakers or fuses just before & after each battery !

In other videos on this topic, they'd run the ground from the starter battery. I always wondered why they didn't just ground it to the body like you did. I'll do it your way now that I've seen it work.

Very neat. The essential battery isolator. Wires run above the floor. You should never plug a gigantic 1500 watts into a 1500 watt inverter. Short uses can be 750 watts sensibly. You should also add a squarish, not long, 100 watt solar panels and solar charge controller. Soon, you'll want a few remote cigarette lighter plugs and a 12 volt chest freezer. Mine runs on 31 watts and always on ECO mode.

Awesome

Clean Install definitely deserves a like 🦾🙏😊

Great video! So very easy to understand. Can you link to the supplies you used?

Thanks

So helpful thank you got an update video how’s it doing still

Thanks for the tutorial video. My question is regarding the terminal connectors. I’m confused on what to get to make these connect to the battery posts.

Thank you, I haven't done this install since i was kid . You filled in all the gaps. Thank you kindly. And may I say that is a breathtaking peace of property!'what stAte is it if you don't mind my askib ,Im going to guess Pennsylvania

Great video man! I would advise you to replace that circuit breaker with a normal anl fuse and later add 12V DC DC charger for your second battery! These circuit breakers are actually trash, they will trip way over your rated amps, and your cars alternator will never actually charge your second battery! Tried and tested both of these ideas!

I’ll be working on a slide in truck camper build this upcoming spring. This setup would work perfectly for my electrical needs. If you keep within wattage from batteries to inverter could you install multiple batteries on the camper side? Great tutorial btw 🤙🏼

very good info, thank you. How long will that battery run that heater?

10 x better than a power pack / jump box. the jackery 1000 is $1100, and the battery is non replaceable, so when the battery goes the whole thing is junk, and all batteries go bad , but this way you can replace the battery, you can pick one up at any auto parts store

Do I need that little circuit breaker between the secondary battery and the inverter?

Excellent, now a question. Can you also connect a power converter and a stereo amplifier to that battery?

This is what I am looking to do as well. Thanks for posting. Do you have an idea on what would be the draw down time on 6 amps continuous draw?

How long will that battery last with the heater on?

Good job I have been thinking about this as well, but I was wondering 3rd battery and inverter or battery generator ?

I wonder if I can keep my sub and amp with this setup.

Ty. Will it work if i have 2 starter batteies connected together under driver seat in my ford transit please ? thickness of that thickest wire please.

Great idea, and simple setup. thanks for sharing! Question: You said you put in a 100 amp breaker? Wouldn't that limit your draw to 1200 watts? Since 12V battery x 100 amps would be 1200. how are you able to draw 1500 watts then without tripping it? Shouldn't that be 1500/12 = 125, so requiring a 125 amp breaker?

Great video, but a quick question. With the 100amp fuse, aren’t you basically limiting the flow to 1200w, and shouldn’t the 1500w heater have tripped the fuse? Or am I missing something (which is quite possible 🙂)? Thanks.

Is that what I need if I want to add a small fridge and TV to my van build

@parttimecamper5561 This is exactly what I was looking for. Direct and straight to the point. Question for you, have you had any issue with charging your secondary AGM battery with the amount of amps your alternator puts out as it differs from your starter lead acid battery? I know they have different charging rates. Will this shorten the battery life of the AGM? I use my work van everyday but only got the inverter to run a space heater when needed and a tv for the kids. But that’s it. And my inverter is way over the top for anything I would ever use 😂

I notice that the inverter have a ground screw... Is it necessary or it doesn't need it? Thanks.

How longs a battery last with a 120v heater?

Great video! What gage wire from the starter battery did you use?

This is exactly the video I’ve been looking for. Thank you for making it clear. I have a question. I’ve got room to put the second battery under the hood. Would you think that would be ok to do? Then run the cables from from the battery under the hood to the inverter in the bed??

I’m doing this instead of my original thoughts now BUT Can you add solar?

Awesome!! Is that a closed cell battery 🔋?

Can a marine RV battery be ok for 3000 watt inverter or is that a bit too much watts to pull? Maybe 2 battery 4 3000 watt inverter. Thanks for all the help on uTube

Please put that braker within 4 inches of the main battery.... there is nothing protecting the massive positive cable.

This is a great video! Question. Would something like an 8 gauge or 10 be better? I was told that a #1 would be too big and have more resistance.

in this project when you put on the 1500 watt heater you turned on your truck or turned off you used the converter

I would buy a battery mounting bracket to install second battery in the engine compartment

Could you install a solar panel to this setup to keep the house battery topped off when the truck is off?

What is your alternator size? And the type of second battery? Im also curious on this setup. But some says that the deep cycle battery will be died early since the charging patterns are different.

Do you have an independent charger for the auxiliary battery? Or do you just rely off the alternator only?

Why did you put in a circuit breaker? Pretty much all inverters come with replaceable fuses. My little 750W has 3x35s in the back that are replaceable. Is it for redundancy?
