Thank you for having such a well made video and presenting it very well. The production quality is superb. I'm tired of videos that are hand held and looking like they're taking us on an earthquake or roller coaster. Not only is this made to professional standards, but you know what you're talking about and enjoyable to watch. Even for us mates over here in the States. 😃🇺🇸👍 Bravo! Keep up the great work.
Finally! Superb teaching, straight to the point, the exact amount of "dumming it down" you guys did an excellent job! I feel like I can actually make an intelligent buying decision......finally. Thank you for getting it done for us!
Thanks!!! After long long hours and weeks searching on RUclips finally I got it how it works !!! Well explained in 10 minutes Well done :-) Greetings from Europe !!
I've watched a few videos and just accidently lost an hour of my day. Great videos. These are some of the most professional how to videos I've ever seen. Subscribed!
Really great vid guys - earned yourself another subscriber. Easy to follow without pushing products too much and really well explained. Can hardly wait for Part 2 and 3!
I'm currently homeless and just got a vehicle to go nomadic. I'm planning on using a 2001 Toyota avalon. It's small, but it's all I need for now. I think I found the right place to figure some stuff out.
I am using an MPPT CHARGE controller, during sunlight hours once the battery is charged I'm on boost mode. That allows me to use the extra power a fan without discharging the battery at all.
Be great if you could do a video of setting up a system at home backup system for extended power out SHTF scenario - ESPECIALLY in these times. Cheers! (Ie no car no power)
Using a Heavy-Duty True battery isolator provides several advantages for truck with auxiliary battery Reliable Battery Management: Automatically ensures the starting battery is charged first, then charges the auxiliary battery, preventing the main battery from draining and ensuring reliable engine starts (True Battery Isolator). No Voltage Drop: Unlike traditional diode isolators, True isolators have no voltage drop, maintaining optimal charging efficiency (True Battery Isolator). Dual Sensing Technology: Monitors the voltage of both batteries and engages charging for both if either battery is receiving a charge, which is particularly useful when using external chargers (True Battery Isolator). Durable and Compact Design: Built to withstand harsh conditions with features like waterproofing, heat resistance, and anti-vibration casing, ensuring longevity and reliability in various environments (True Battery Isolator) (True Battery Isolator). Easy Installation: Simple three-wire installation without the need to bypass existing alternator wiring, making it user-friendly even for novice installers (True Battery Isolator). Cost-Effective Solution: Provides a budget-friendly way to manage dual battery setups effectively, offering long-term savings by extending battery life and preventing failures (True Battery Isolator). Safety Features: Includes ignition protection and operates within a wide temperature range, enhancing the safety of your vehicle’s electrical system (True Battery Isolator). Overall, the True dual battery isolator enhances the reliability, efficiency, and longevity of a dual battery system in various applications, from trucks to boats and RVs.

8:01 Using the 100Ah battery as their example, the battery that drains their battery to only 20% full or 80AhX250 cycles=20,000Ah for the life of the battery. Next one 50% full or 50AhX500 cycles=25,000Ah, finally the cycle that the uploader is recommending is 80% full or 20AhX1,200 cycles=24,000Ah. As you can see in this scenario it's actually best to drain your battery to 50% as you get the most Ah of all the examples. In fact their is only 20% difference between the best and worse case scenarios. I think the most important message for people is to never drain your battery below 12 volts as below this amount you can damage your batteries and significantly damage your battery. Make sure you have an automatic cut off switch that protects your battery from deep and catastrophic damage to your battery.
Almost perfect vid. Awesome for 1st timers and really showing people it's simple stuff. Only correction is the amp delivery from that 200w solar panel. That current was in relation to panel voltage. The regulator will drop the volts from 21ish volts down to 13-15v (depending on charge setup), which in turn raises the amps. Watts 101 is p=v x I so say if your regulator is outputting 14v you will be seeing closer to 15amps (50% more than what the panel outputs directly).
Glenn Matthews you’re spot on and good pickup, but what I forgot to mention is that it comes with a PWM regulator - so not a great buck converter. If you used an MPPT solar controller you would get a much better power output with higher amps as you said, but I’ll go into that more in part 2. Thanks for the comment and cheers for watching! Thanks, Cahn
@@4wdsupacentreAu no worries mate. Helps that I'm a sparky lol. Totally agree, just pointing out the relationship between volts and amps with a constant wattage. Love ya gear and the wicked prices. Keep up the good work 😊😊
yeah, you're right haha. Hopefully any other more technical folks will see your comment and understand it anyway... but for the basics I figure this will help new 4WDers and campers! Cheers, Cahn
This is why MPPT charge controllers are way better than PWM. You can effectively run a much higher voltage solar panel set up and convert all those extra volts, into amps. Provided the battery can accept the elevated charge rate though.
You forgot one big advantage of having your second battery in the engine bay. Space! My Jeep has bugger all space in the back but loads under the bonnet. So that’s where my battery lives!
Nice accurate advice. Very few people know that your start battery only has 2 functions. 1. To start your vehicle. 2. Provide and electrical sink whilst the vehicle is running. It is not for anything else !
Depends, if you have older car then yes. New cars with start/stop and other stuff work differently, some of them even have secondary battery that power all of your electronics so voltage doesn't fluctuate when you start your car.
@@cekpi7 still the same. Second battery is providing a stable electrical sink voltage under crank and the stop/ start variants use a more durable battery to allow more starts.
@@JRiddledickDangerfield Secondary battery is used to run vehicle accesories while car is turned off as well. Your point is still valid, starter battery doesn't do anything else than starting a car.
got an ambulance with 3 batteries and 4 charging systems. 2 alternators independent, solar, and shore. now thinking doing some voltage smart idolators to connect the independent systems,
Why would my switches on 12 volt control box all have permanent power on regardless that they're through the switches???? I followed install instructions. ???🤔
So it can run the fridge and be charged from solar panel at the same time if using the battery box? I just had my Kings MPPT solar controller kill my battery. Came back and it was bubbling, and not a lithium battery. Not set up as a dual battery, just charging from solar, and running camp fridge.
Save alot of money by simply replacing that silly roof tent with an awning tent, and roof mount a 300W solar panel. That way you won't ever need to connect the extra battery to the alternator. Especially in Australia.
@8:03 using your numbers on discharging to 20%, 50%, and 80% - then 50% discharging would get you more amp hours mathematically? Using a 100ah battery to 50% = 25000ah while 100ah battery to 80% = 24000ah?
Can I use this system on my overlander, I'm using bed rack and I'm thinking what if the system gets wet in raining weather. Should I install the panel behind the rear row seat?
Running a dual battery setup in my Grand Cherokee Trailhawk. My question is: Do both batteries need to be the same? For example, I would like to get Lithium battery to run my camping gear. I plan on using a DCDC charger between the two.
If I am unable to hook up the ignition wire, can I just plug my dual battery in when driving and then disconnect when not driving to ensure the power is only being drained from the dual battery and not the main? Thank you

Greetings from Europe !!
Very cool.
Good information.
Greetings from South Florida!
Just received one from my gf as an early Christmas present. Just the video I was looking for.
I've watched a few videos and just accidently lost an hour of my day. Great videos. These are some of the most professional how to videos I've ever seen. Subscribed!
Glad you like them!
I loved the closed captions trying to keep up with the Aussie accent. The unit of measurement for battery life is apparently 'air bears'!
🤣🤣🤣 you need plenty of air bears when out camping. Also, watch out for the drop bears!
As a newbie to the 4wd scene thanks for explaining this in such an informative but easy to understand way!
So well explained! Probably the best video on YT that covers this topic. Thanks.
Great video I'm turning my station wagon into a little camper so we can sleep in it have nights away at the beach etc. Such a detailed video. Cheers.
Doing a van conversion and this channel has been super helpful, I live next to one of your Wearhouses, I'll be sure to come down and buy some kit
Hi great Video and info just bought solar panel and 115 Ah AGM Deep cycle Battery now i know how to set up Thanks heaps
Extremely well explained with the water tubs! Kudos to your team. Very informative overall. Looking forward to digesting parts 2, 3 etc. Cheers, DD
Very comprehensive, it took quite some time to fined the right Video. Really appreciate learned quite a bit. Many thanks.
I finally get it. Thank you! Best video on this topic so far.
And here I am thinking about adding a 4th battery to my Stock Dual battery setup.
Really great vid guys - earned yourself another subscriber. Easy to follow without pushing products too much and really well explained. Can hardly wait for Part 2 and 3!
I echo the same sentiment as the last post. Great information, very clear for people learning about this and we'll presented. Thankyou.

I've trwaled through loads of other videos spending hours watching. You have said this 10 mins. Look forward to part 2
Great vid, exactly what I have been looking for. I want to free camp as much as possible.
Nice video, would love to see a build video of your panel fixed at the back of the canopy, looks cool.. Cheers
Keep an eye out - we'll have some more vids on it in the next couple of weeks!

Easy giveaway for formulas is the rating name. AH is amps X hour.
SUCH A GREEEEEEEEEEAT VIDEO! looking forward to watching the other episodes.
Good piece, thanks. I'm well advanced but my kids will 'get it'.
Cheers Stuart - we wanted to start with the absolute basics! Thanks for watching regardless!
Cahn
Wow! Even I understand

Nice vid, buying a troopy and needed to know how this worked. Will be watching the other vids. Cheers.
Glad it helped
I do RC car racing and need a field battery to charge my 4s lipo batteries. I think a deep cycle and solar power will work great...
Gee, you really make a great video. When I can upgrade to a car though. Thanks for the lesson.
Thanks mate👍
Good video mate ! 🇨🇦
This is exactly what I have been needing ! Thanks guys awesome
Cheers for the feedback Dan,
Hopefully Pt2 is just as helpful haha
Thanks,
Cahn
Thank you very much 👍👍
You taught me something about batteries thanks mate cool shit!
Just what I needed too
Incredible, thank you 🙌🏽
Glad you liked it! Cheers, Ashleigh

Thanks a ton
Keen to know more on that power supply board also keen to see parts 2,3 and on if it goes past part 2
Easy to understand. Thanks for the vids
No problem!
Good video
Subscribed, greetings from Kenya 🇰🇪
Great vid guys. Perfect for the DIY dual battery set up.
got an ambulance with 3 batteries and 4 charging systems. 2 alternators independent, solar, and shore. now thinking doing some voltage smart idolators to connect the independent systems,
will you try TrueAm dual battery isolators and see the diffence
Great video. Crow✌️
Gday Cahn, is there a video on how to add a 12 volt accessory panel off the main battery into the back of a ute wing kit?
Hey My Man! Great vid. Did hear you say I can't keep my diehard agm under the hood as a secondary?!
Excellent info thanks!
Cheers Nick, keep an eye out for pt2!
Thanks,
Cahn
Can see a control panel over back of the head board, are they on the website?
Not yet Peter, keep an eye on the website!
Thanks for the info. Answer some of my questions in my head...good job👌
Glad to hear it!
Thanks for a great video guys very helpful
Glad you enjoyed it
I subscribed....great vid, mate. Direct and to the point. Cheers!
Thanks for the sub!
Awesome!!!
Thank you. Just starting out on this journey to understand the basics. Appreciate your time to make the videos.
No problem!
Why would my switches on 12 volt control box all have permanent power on regardless that they're through the switches???? I followed install instructions. ???🤔

I just had my Kings MPPT solar controller kill my battery. Came back and it was bubbling, and not a lithium battery. Not set up as a dual battery, just charging from solar, and running camp fridge.
how about a Toyota Prius having a dual system for off grid extended camping
Great video, nice info
Great presentation cheers mate 👍🏻
Thanks for the visit :)
Thanks from over the ditch
Like your videos , but is there anyone in the states doing this?
Can I charge my VAN Parallel (Auxiliary) Batteries through ISOLATOR to connect with Smart Alternator.
Is the fridge only using 12watts?
seems too little if you ask me. i have one and it uses about 4 amps

Hi I want to run 2 x 110ah an inverter and some led lights in my small garage. Can you help me with a diagram please?
Hello! can I charge my Ecoflow Delta 2 removable lithium battery with a DC/DC charger while driving? thanks so much!
Great vid. thanks
No problem 👍
Can you connect 2 kings battery boxes together? If so, how?
Thanks for the great video!!
Just wondering what charger you used to charge the battery in house ?
Can I use this system on my overlander, I'm using bed rack and I'm thinking what if the system gets wet in raining weather. Should I install the panel behind the rear row seat?
Running a dual battery setup in my Grand Cherokee Trailhawk. My question is: Do both batteries need to be the same? For example, I would like to get Lithium battery to run my camping gear. I plan on using a DCDC charger between the two.
I should note the car battery is NOT a lithium
Hi mate. Can you add a second auxiliary battery to a batter box. Not sure if you would have to re run all the earth cables off the second battery.
Hi can I change the cig charger to a smaller one that runs my Engel
This is why lithium is king
If I am unable to hook up the ignition wire, can I just plug my dual battery in when driving and then disconnect when not driving to ensure the power is only being drained from the dual battery and not the main? Thank you
Hi there,
This is one way you could do it!
Cheers, Courtney
My inverter has a fault light on and I don't know why
