2018 v6 Amarok 12v Aux question

Hey guys - I have a question.

Currently the 12v cigarette plug sockets are always on, which means that anything connected to these sockets whilst the engine is not operating they will draw current and drain the battery.

I have an Escort Passport Max (radar detector) connected to the socket on top of the dash and my concern that if left for a long period of time the battery could be drained flat. The unit draws approx. 300mA of current when on.

So the question is, is there protection circuitry in the Amarok to safeguard the battery from going flat? e.g. it will disconnect power supply to the aux sockets? Or is it ok to have this device always on?

Or is it recommend to rewire this so that power is only supplied when the ignition is on?

Keen to hear thoughts on this.

(2018 HL V6 Amarok)

    If the accessory points are oem, the battery senses drain and will cut power

    On ours (Core Plus), all points are ignition on only but moving the fuse up one powers them on all the time but no battery sensing AFAIK

    Hi yes, all the power points are factory - and I am using the one in the tray on top of dashboard to power the radar detector. so you are certain it will cut power if senses drain?
    I hear the batteries are NZD $800+ for these utes so would hate to damage it

    As you are in NZ, who knows what VW NZ do - LOL

    Ask the dealer. That way it falls back on them if **** goes down

    I had a fridge plugged into my socket to the left of the console overnight and it drained the battery so that I couldn't start the car the next morning. Mine is a 2017 HL V6. So I don't believe that there is battery protection on these 12V sockets.

    thanks guys - I have also asked the dealer to look into this too

    Definitely always on, 24/7, and will continue to power through to running the battery dead flat... There are a few dealerships that got caught red faced when the V6 came out and the left accessories plugged in over the weekend!

    If you want "undervoltage" protection, install a PowerMagic Pro... Made for dashcams, but they cutout at a preset voltage (or time) ensuring you don't drain the battery!

    I just checked in with the South African owners and there V6s (2018) have battery protection

    Which is why I would check with dealer since you are in NZ
  • Hi All

    Just taken delivery of a 2019 Sportline and looking at dual battery options; wondering if anyone can confirm if the Aus models do or dont have low voltage protection?

    Thanks

    Hi Azzad,

    ive nearly finished hooking mine up.

    ive run a 2B&S welding cable (dual shielding and high temp resistance) in corro from start battery to tub with a 100A in-line circuit breaker as close to starter battery as possible.

    it runs to a Projecta IDC-25 charger. I have also mounted a 100w solar panel on the sports bar and run 8B&S cable from this to the IDC-25.

    https://www.automegastore.com.au/projecta-idc25-25a-3-stage-dc-solar-battery-charger-version-4

    i have mounted a battery tray with a 140AH AGM in the tray on rubber mounts. The IDC-25 is run directly to this as well as the fridge hardwired to it.

    https://www.aussiebatteries.com.au/batteries/deep-cycle-agm/140ahx-12v-agm-deep-cycle-battery

    next step is fuse box and switches for fridge, compressor, tub lights etc etc.

    however, I didn’t know anything about a battery protection on the Highline... keen to find out though.

  • Thanks doinitsideways

    I was originally thinking that if there was a low voltage cutout, I would mount a second battery under the bonnet and just parallel the 2 batteries together, however it doesn't appear that you can fit a decent size battery under the bonnet and not sure about the low voltage cutout yet.

    So I will probably do a second battery in the tub or under the tub and use a dc-dc charger. I have traditionally used CTek gear but I will check out pricing of the redarc and Projecta equivalent. I have a portable solar panel that we take when needed.

    Did you run both + and - from the starter battery or have you picked up - at the tub somewhere?

    @azzad, in my rok i run a piranha battery tray, had to slightly modify it, as like you said there is not much room under the bonnet! I've welded a plate onto the side of it to mount the C-tek 250sa dc/dc & to also hold the water pump, as this has to be moved in order to fit the battery tray under there. The downside to it is that i could only get a 65A/H battery underneath there because anything bigger was too high. That being said for what i have i only power my fridge off it, it charges when im driving & then when im at camp i have the solar out so it suits me & the type of stuff i do.


    Cheers


    Jonno

  • Thanks Jonno

    Any pictures of the under bonnet mounting?


    Daz

  • doinitsidewaysdoinitsideways Junior Member

    sorry Azzad, V6 has no room for battery at all. I believe the 4 banger can be juggled around to fit one as John has mentioned.

  • Thats what I thought but Jonno gave me hope again :(

    Daz

  • doinitsidewaysdoinitsideways Junior Member

    Are you V6 or 4???

  • doinitsidewaysdoinitsideways Junior Member

    Same as me mate, I’d be fucked if youd fit anything under the bonnet. And I haven’t found anyone who has... that’s why I ended up mounting in the tub. I know on the modrok forum a few have made up a tray for under the tub to use two slimline sealed batteries...

    what do you need to achieve? Backup battery for cranking/winching? Or just running accessories such as fridge etc?

    Ive circled the Ctek battery sense https://ibb.co/cQCsTtX

    Where i had to cut the battery tray i put extra hose on the corner just incase it rubbed through https://ibb.co/pvyRFSq

    This is a view of the plates i added that support the water pump & the C-Tek charger https://ibb.co/CH8LZ09

    This is the plates - the black one is welded to the battery tray & the other one is stuck to the c-tek charger and has 2 bolts that go into the black plate, then the waterpump is just off this aswel https://ibb.co/6r5HvDG

  • I'm only running a fridge and charging a couple of phones, I have gotten away with a single 105 AH supercharge allrounder as an aux, in the last couple of utes but they have been trays not tubs and permanently mounted. This time with a tub its not as easy to fabricate a box or mount underneath. At this stage I am trying to find a good battery box that ideally has, several USB outputs and anderson inputs and outputs with a good built in battery voltage display. Intergrated DC-DC charger would be nice but happy to do an external 1 as well.

  • doinitsidewaysdoinitsideways Junior Member

    I have spotted a battery tray that mounts over the wheel arch permanately in the tub... not sure where it was though sorry.

  • Ended up going with 1 of the "Home of 12 Volts" boxes; and a Projecta dc-dc. I was original turned off of the Project as read they had numerous issues with the solar input but I was assured that it has been fixed; I guess time will tell.

    Still waiting on my bedrug to turn up before I work out how to mount it all.

    Daz

  • doinitsideways, did you hook up the pink switched 12v wire to the projecta? Manual suggests that with a smart alternator you need to connect this but place of purchase suggested you don't. I haven't hooked it up yet and have seen the project indicating it was trying to charge the aux battery when the ute wasn't running on 1 occasion.

    I was hoping that the 13 pin european trailer plug would have the switched 12v at it that the pinouts I googled suggested it does but after pulling it apart it isnt there.

    Daz

  • doinitsidewaysdoinitsideways Junior Member

    Daz,

    I’ve left mine not connected mate.

    havent had an issue so far.

    i believe the rok isn’t a smart alternator. It starts at a higher voltage and drops off... but not below the 13v mark... you will see it still drawing power from your main battery to charge the aux batt until your main gets down to 12.4??? Volts I think it is...

    cheers,

    Josh

  • Not sure I like the idea of it drawing the main down to 12.4 all of the time, thats about 75% capacity I think, seems like it would shorten the life of the battery.

    D

  • doinitsidewaysdoinitsideways Junior Member

    Just checked... it is 12.8v turn off.

    with smart alternator connected it will draw down to 11.9

  • doinitsidewaysdoinitsideways Junior Member

    Only draws down to 11.9 with ignition on and smart alternator wire connected to ignition.

    when vehicle is off it still draws main down to 12.8v.

  • That sounds better, I have to admit I havent re-looked at the manual myself to work it out.

    Thanks

    For those looking for a battery box Korr lighting has a good one with a DC-DC charger and a VSR. Would only fit in tray though.

  • doinitsidewaysdoinitsideways Junior Member

    Russ, just had a look at this and noticed it says you can connect a dc-dc... it’s not built in...

    looks like a good little bit of kit though...
