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.
Y'all. This was so well put together. The best work I've seen in explaining the topic. THANK YOU!
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 TH-cam finally I got it how it works !!! Well explained in 10 minutes
Well done :-)
Greetings from Europe !!
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!
Extremely well explained with the water tubs! Kudos to your team. Very informative overall. Looking forward to digesting parts 2, 3 etc. Cheers, DD
So well explained! Probably the best video on YT that covers this topic. Thanks.
Excellent video. Great information that is not provided on other channels.
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.
Thank you. Just starting out on this journey to understand the basics. Appreciate your time to make the videos.
No problem!
I've trwaled through loads of other videos spending hours watching. You have said this 10 mins. Look forward to part 2
superb video ,thanks for taking time to explain to new camping enthusiast.
Thanks for these videos. You guys really have a great way to take something that looks difficult and show it as something that really isn't.
Their videos are great for tips before you buy quality gear!✔️
You answer so many questions and make it sound logical... I’m know a subscriber and fan
As a newbie to the 4wd scene thanks for explaining this in such an informative but easy to understand way!
Great vid, exactly what I have been looking for. I want to free camp as much as possible.
I echo the same sentiment as the last post. Great information, very clear for people learning about this and we'll presented. Thankyou.
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
Just what I needed thanks!
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 finally get it. Thank you! Best video on this topic so far.
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!
Very clearly explained with great visual reinforcement. Have subscribed. Look forward to following your channel 👍
Thanks Tim,
Glad it was helpful!
Cheers,
Cahn
Very comprehensive, it took quite some time to fined the right Video. Really appreciate learned quite a bit. Many thanks.
Very cool.
Good information.
Greetings from South Florida!
Great vid. Shopping for Kings gear now.
Subscribed, greetings from Kenya 🇰🇪
Great presentation ... and thanks for the product links
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
Just received one from my gf as an early Christmas present. Just the video I was looking for.
I was stuck on putting battery under hood because there was a spot for it. Now my setup will be easy battery in back charge off the tow aux power. Tow aux power my truck cuts out at 10 minutes. This will be so easy now. Thanks.
Thanks for the info. Answer some of my questions in my head...good job👌
Glad to hear it!
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.
Great vid guys. Perfect for the DIY dual battery set up.
Good video mate ! 🇨🇦
Thank you, great video!
Great video, nice info
I subscribed....great vid, mate. Direct and to the point. Cheers!
Thanks for the sub!
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.
Just what I needed too
Easy to understand. Thanks for the vids
No problem!
Nice vid, buying a troopy and needed to know how this worked. Will be watching the other vids. Cheers.
Glad it helped
Incredible, thank you 🙌🏽
Glad you liked it! Cheers, Ashleigh
Nice video, keep them coming 👍
Thanks, will do!
Gee, you really make a great video. When I can upgrade to a car though. Thanks for the lesson.
Great video. Crow✌️
Great video!
Thanks mate!
Thanks for a great video guys very helpful
Glad you enjoyed it
Excellent info thanks!
Cheers Nick, keep an eye out for pt2!
Thanks,
Cahn
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
Great presentation cheers mate 👍🏻
Thanks for the visit :)
And here I am thinking about adding a 4th battery to my Stock Dual battery setup.
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.
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
Thanks for the great video!!
Just wondering what charger you used to charge the battery in house ?
Good video
Have a camping trip in the start of January are the control panels gunna be released before Christmas??
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)
You taught me something about batteries thanks mate cool shit!
Subbed. Looking forward to Pt.2.
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.
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?
Do you have videos explaining how to set up a DC to DC charger and a LifeP04 battery system?
Thank you!
Awesome!!!
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!
Cheers,
Cahn
*very helpful*
Thank you very much 👍👍
Brilliant! 🙏
Thanks for the great vid! :)
My pleasure!
will you try TrueAm dual battery isolators and see the diffence
You're a detailed educator mate...
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.
A little bit off-topic but how close together can you place two of your slimline batteries together? It is for a rear compartment of a camper trailer. I was hoping to keep as much room as possible for other electrical gear.
Hey My Man! Great vid. Did hear you say I can't keep my diehard agm under the hood as a secondary?!
Thanks a ton
Wow! Even I understand
Keen to know more on that power supply board also keen to see parts 2,3 and on if it goes past part 2
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!
Great vid. thanks
No problem 👍
Like your videos , but is there anyone in the states doing this?
I’m building a 2020 Silverado 2500 HD for overlanding. It comes with dual starting batteries since it’s diesel but I would like to install 1 or 2 batteries in the back of the truck to run my 4 diode dynamics SSC1 camping lights and a Dometic CFX3 55IM refrigerator. What would be a good set up for this?
Can you connect 2 kings battery boxes together? If so, how?
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?
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!
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.
Is the fridge only using 12watts?
seems too little if you ask me. i have one and it uses about 4 amps
Problem: I have a 1999 Suburban with a secondary battery tray. I want to install a second battery with a VSR Battery Doctor (Wirthco brand) that has an "Override" button for jump starting off the secondary battery. My problem is I have all my camping accessories wired to the main under hood fuse box, which is connected to the primary battery.
Question: Is it OK to pull the fuse box cable off the primary battery and hook it up to the secondary battery, so I can use my accessories?
If by chance I accidentally ran the secondary battery dead, would the "Override" button work to power the starter relay and ignition system to start the engine?
Hello! can I charge my Ecoflow Delta 2 removable lithium battery with a DC/DC charger while driving? thanks so much!
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.
Easy giveaway for formulas is the rating name. AH is amps X hour.
Hi can I change the cig charger to a smaller one that runs my Engel
How do you make one of the Anderson plugs into a solar input please make a video ?
You’ll need a DCDC charger with solar input, wire the positive cable from the Anderson (it’s already got a connector so easy to do) into the solar input on the DCDC. Alternatively you could mount a solar reg in a similar way, using the positive from the Anderson into the reg then the negative from the reg to the busbar in the control box!
Cheers,
Cahn
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
Can I charge my VAN Parallel (Auxiliary) Batteries through ISOLATOR to connect with Smart Alternator.
Thanks from over the ditch
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...
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,
Great video! Excuse my ignorance, I have a question, I have 3 agm 125 amp hr. batteries all in series, connect to my 3 (100 watt solar panels) also connect in series .Do I have to recharge them individually when there about to go below 50 percent, or can I leave them in series and have all three batteries recharge at the same time. ( Have a battery charger and a 2000 Honda generator).
Are you sure they're in series? if so they're running at 36V 215Ah.
If they're in parallel then they're 12V, 375Ah. Yes you can charge them all together if this is the case - just connect the positive lead of the charger to the first battery and the negative to the furthest battery. that way it's charging equally through all three.
This is a good link to check out for more info: www.impactbattery.com/blog/tutorials/how-to-charge-marine-and-rv-batteries-in-parallel/
Cheers,
Cahn
Thank you so much for replying! Yes your are right. The batteries are connected in parallel.
2 solar are in series and then in parallel with the 3rd one. Again thank you, I will look into the attachment you send me. I'm glad I found your channels and have subscribed to your channel. Thank you, thank you.
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
