Step-By-Step DC-DC Charger Install

[@principal7819]

Best step-by-step installation guide of any dual battery system I've seen. Thanks guys!

[@adambailey9290]

Legend!! I have just been looking at getting myself a 12v setup but didn’t know where to start. Now I can just follow this video step by step. Would love to see a video on how a inverter would connect up to this setup

[@4wdsupacentreAu]

G'day Adam, Ideally you'd connect your inverter directly to the battery (with a fuse on the positive lead) so you can run the shortest possible wires and prevent voltage drop. You could use the internal posts on the battery box to connect your inverter - connect red to the aux battery post and black to the negative post and it would work, but if you were planning on running any high power tools or appliances, you'd likely want to increase the wire diameter running from your aux battery to the posts in the box to cope with the extra load! keep an eye out though as this is something I'll add to my list! Cheers for watching and shooting through a comment, Cahn

[@Wiradjuri217]

This confirms I'll be getting someone smarter than me to install 😆 however this, as all the 4wd supacentre videos are, is a great tutorial

[@samanthaponga9278]

Totally.

[@einfelder8262]

I never had to connect my DC-DC charger to ignition for it to work (no smart alternator to worry about), and it didn't have a plethora of wires to hard-wire battery type. Mine had a push button selector for battery type. I have moved this unit into my caravan now as I have installed a DC-DC MPPT device into the car - this charges the house battery from solar or alternator (no ign wire needed) and when full it charges the start battery as well. The van is simply connected with anderson plugs and decent cable.

[@drewhodge3820]

Great bit of kit. It would be a lot better if you supplied the charger with longer wires on the heavy gauge wire. At least an extra foot/30cm of wire. Also supply the crimp ends and the crimps to extend/join the longer cables.

[@4wdsupacentreAu]

G'day Andrew - Definitely something I'm pushing for mate! Would've made my job a lot easier too on this install... Thanks for taking the time to watch and shoot through your feedback! Much appreciated! Cheers, Cahn

[@drewhodge3820]

@@4wdsupacentreAu Thanks for the prompt reply. My thinking is that a lot of people wont want to spend an additional 45-50 dollars on a crimping tool, (which will put a lot of people off buying this unit) just to extend those two heavier cables. Most people are capable of joining/extending thinner cables and they will find it easier to find the thinner gauge wire. Personally i know i can get lugs to extend the heavy gauge cables but they are not readily available to most people. That additional cost 45-50 dollars for a crimping too might make people look at other suppliers, which would be a real shame because your DC-DC charger is brilliant bit of kit. When you consider the two extra 30cm wires will only add a dollar to your build cost. P.s Keep up the great work.

[@stevecrowe176]

Just an observation. I've watched a heap of 12v 2nd battery install vids last 2 weeks. Everyone uses the word "battery" when referring to "this red wire attaches here to the +, or the black wire goes here to the -" without defining WHICH battery they're referring too! The vehicle main battery OR 2nd battery mounted on the 4x4 tray or box trailer. Most people could possibly know what you're explaining and fill in the gaps, I'll admit l don't follow everything. I saw on a web page today where a person uploaded a pic of his system drawn on paper in red and black pen representing the wires, that was very informative. Sadly l can't upload it. That's be great if you could provide something similar, sketching the Control Box, Battery Monitor, DCDC Charger, Main Battery, 2nd Battery, Inline Fuse Placement, where each wire goes the wire gauge and fuse size/placement etc etc. Even include the the wire gauge for different applications. E.G. Min 8 B&S gauge Black & Red wire from Vehicle Battery (to the KINGS control box) E.G. 2mm can be used for all LED lighting. Don't assume everyone does know. Has Adventure Kings contemplated running workshops for 12v second battery installs at one of their outlets??? Say 8 - 12 vehicles at a time with a nominal fee especially if the individual purchased all Adventure Kings 12v systems, with some freebies, discounted accessories on the day/night etc. Even 12v question/answer evenings? Just thinking outside the square. Sorry for the long post. Anyway, thank you for your vids, really enjoy them. Cheers

[@lifeisawesomeeveryday9734]

do you have a video on how you build the internal,box for the storage of battery ect

[@4wdsupacentreAu]

Hey mate, I don't have any plans or a video on it unfortunately - I just knocked it up the day before with some ply wood and marine carpet. It's a vertical piece of ply with two horizontal sections - the main shelf you see in the video (which has a couple of 45° supports underneath) and a top hat that encloses the box. I also put an end cap on the headboard end of the unit to box it in. I sized it so that it fit over the width of the drawer wings and doesn't interfere with the fridge slide, and I made the main shelf high enough that you can slide a battery underneath. it's mounted to the bottom corners with L brackets, and the top corners use straight twist brackets (90° Twist) to fasten to the internal bracing in the canopy. If i did it again I would've added some low dividers on the main shelf to prevent gear sliding around - we use the control box to charge batteries, cameras, phones etc and it'd be nice to keep them in the one place! Cheers, Cahn

Hey! Awesome video really helped in the install of this in my van, thanks! I have a question: Straight after I installed this dual battery system into my van (VW transporter T5 2014, with smart alternator), 2 engine warning lights came on the dash. I’ve check the alternator in the van and the main van battery using a multimeter and both are testing up as normal. I’ve definitely connected the ignition (blue) wire into a positive ignition power source. Does anyone has some insight into this? Thanks heaps! 😊

[@4wdsupacentreAu]

Which warning lights are they? It could be from disconnecting the Battery while you were connecting everything… Alternatively your particular model may have a current sensor on the negative terminal of the battery which you’ve unintentionally bypassed by connecting the DCDC wiring directly to the battery. If that’s the case, connecting the negative lead to a body earth NEAR the battery terminal can solve it! Might be worth doing some searching to see if other people have had a similar issue.. It could also be a coincidence… which has definitely happened to me before when I fixed something and an unrelated part broke the next day haha Cheers, Cahn

[@4wdsupacentreAu]

Hey mate, Most DCDC chargers work as an isolator and don’t need a VSR (including Kings) But if you did have a VSR you’d need to connect the + input wire of the DCDC to the wiring of the VSR keep in mind that you’d need to make sure the wiring was the correct gauge etc and that adding the VSR inline may actually increase resistance and voltage drop!

[@4wdsupacentreAu]

Hey Karl, It really depends on your setup as to whether it'll matter or not... so let's see how we go! First of all what vehicle do you have as it'll depend if you have a smart alternator? Next can you confirm whether the aux battery under the bonnet is a starter type or deep cycle type? I mean ideally you'd connect your DC-DC charger to your starter battery so you have two distinct systems - that way if your isolator does fail, or isn't charging due to low alternator voltage you're not missing out on charging your battery in the back (or you're not discharging your aux battery into your rear battery, without the alternator topping it back up at the same time!

Hi guys, The temperature sensor cable is too short. Is there a safe way to extend it?

[@deltakiwi]

How'd you go. Mine broke as i fed it through the grommet.

[@ingdanielluna]

@@deltakiwi I just connected it to an earth point in the back of the car.

[@47Thegreatman]

Same thing happened to me. Call the shop and order one. When you get it just attach it to the broken one and the red flashing will disappear. Any problem just message me 👍

Hey guys. the 2 quick connects on the control box. I have a few questions obviously one is set up for solar input. With the other quick connect. Can I run my cable from my starter battery into the Quick connect instead of what you did in this vid? you guys had the pre made cable with the anderson on the end. I presume it was for that reason? if that was the case. Am I able to have both of them plugged in at the same time. Cheers

I’m considering a circuit breaker between the dc to dc charger and the house battery. What is your opinion on this and if you would do it, what orientation should the breaker be set up - what should connect to the battery side of the circuit breaker and what connects to aux? PS this is a stand alone system that has no starter battery involved.

I’m running dual AGMs under the bonnet but want to add a LiFePO4 battery in the bed of my truck. Is it possible to add the third battery to this setup? Also, is this setup weatherproof enough to mount inside the bed of my truck? Thanks

So I have done this and when I attach my kings solar panels I get an over voltage shut down fault what could be happening?

[@4wdsupacentreAu]

Hi there, This can be due to how the circuit was installed, though it's tough to diagnose without being able to see exactly how the control box is wired, and which panels you have in the system. Regards, Andrew

[@mlglxr0770]

Might be a simple question but if I've got the dual Battery set up from king's and the mppt for solar do I need a dcdc in their somewhere??

[@brandonramey1373]

Whats the best easiest solar panels to use with the setup

[@PeninsulaDroneography2024]

Another great informative video. I have a MQ Triton Dual Cab and would love to have a 2nd batter setup in the rear tray. Where do you get the grey boarding from that I see in nearly all of the vehicle setup videos ?

[@Npolis]

did you ever find a answer?

[@PeninsulaDroneography2024]

@@Npolis not really - I ended up just securing the 2nd battery in the back.

Marine plywood, coveted in marine carpet . Stick it on with contact adhesive. Very simple and easy to do.

What do you do with temperature wire if it does not have the right length?

Can the Anderson plugs be used and power outlets as well as inlets?

Looks great, what about adding the Dc2Dc into a caravan, what do we do with the ignition wire, 2017 Pajero Sport, and 22 year old caravan, please advise. thanks

[@davesourdooradenture]

if you look at your trailer plug, you have a spare pin normally used for reverse lights (almost no one has reverse lights on there trailer ). run a fused ignition source to that spare pin, same goes from the trailer side of the plug. Run a wire from the trailer plug to the DCDC charger. Other option, just install a manual on/off switched. when your setting off on the long trip, turn it on

[@JTRulzzz]

To get power to your caravan you’ll probably need to run leads down to the back of your car and use Andersen plugs for the connection between the van and car. With the ignition cable they sell a three pin Andersen plugs for the ignition wire so you can look into that. Another brand uses the three pin connectors but I feel bad mentioning them but it starts with K and ends with ass. Good luck!

[@4wdsupacentreAu]

Thanks George, This is something I'm hoping to do a video on in the future, but: As the other two commenters have said you'll either need to run a fused ignition source to the spare pin in your 7 pin trailer plug near your towbar, then use the trailer end to run to the DC-DC charger OR you can run a separate ignition wire to a separate plug near your towbar. There are a bunch of quick connect options available - if you're after a single plug then the "powerpole" type are good. Cheers, Cahn

[@destinyangel5]

So if your car has the normal alternator and not an emission based smart alternator you don't need this ?

[@4wdsupacentreAu]

Not necessarily, but it means you can sometimes get away with an older tech VSR or dual battery isolator. That’s if you’re using two batteries of the same type (flooded lead acid for example) If you’re wanting to run a Lithium battery in the back (or realistically even AGM) you’d still want a DCDC charger that would safely charge the battery with the correct charge profiles. Cheers, Cahn

[@destinyangel5]

@@4wdsupacentreAu Yep thank you , makes sense now different chemistry needs the charger than can differentiate and then this gives you more flexibility if chop and change batteries types or if you want to plug in solar .

How would you connect an MPPT solar controller to the Anderson plug?

[@jordanquinn7267]

So with this system do I not need a isolator is it built into the system? Thanks in advance great video as well👍

[@4wdsupacentreAu]

That's correct! DC-DC Chargers typically work as isolators either with a starter battery voltage trigger or the ignition trigger. With this unit you can choose either by connecting the ignition wire or leaving it disconnected. Cheers, Cahn
