Is this setup the factory-fit aux battery wiring?

[Paul Binding]

I was going to get a leisure battery fitted before camping season commences and was having a little explore under passengers seat when I came across a nice surprise.
There’s already one there I didn’t no about and wasn’t listed in the ad when I bought the van.
It looks like it’s factory fitted.
Only problem is I don’t know exactly what I have there re chargers,relays etc.
I was hoping somebody more knowledgeable than me might be able to tell me.
I have also included photos under the bonnet, there doesn’t seem to be any relays/chargers there.
So I have attached some photos of my surprise

welcome to T6F

You have indeed got the factory leisure battery kit fitted..

That the 100A relay, 80A Fuse fed from the main Fuse box under the starter battery.

Your relay will be triggered via Engine Run signal from the BCM.


have a quick look here for some back ground. (same setup)

Stop/start...regen...smart Alternator... Dc-dc Charger For Leisure Battery Or Not?

So With all the talk regarding the Bluemotion thing and regen breaking and leisure batteries our T6 has finally arrived. The first thing we done was to checkout the factory fitted setup,...... Stop/start=check, Regen Braking=check, AGM starter battery=check leisure battery under passenger...

This will be your Fuse and relay :





you can just upgrade to a DC-DC charger, more here :

your relay (SCR) charges the AUX battery via this fat cable . .

interesting to see that you have a EFB starter battery . .






and an AGM Leisure battery . . .

It’s a T30 high line with quite a good original spec level.
You have already lost me with EFB & AGM Is that good or bad.

Out of interest, what is the extra battery currently (sorry no pun intended!) powering?

 

[Paul Binding]

I have no idea to be honest. The only thing I have a little bit above standard is an aux heater, and that’s another mystery to me. Not sure if it heats the van, the engine coolant , both, none?
All new to me at the moment and because of lockdown had had the chance to get out and use it to find out.
I’m hoping it will power 6 downlighters, a couple of double usb sockets and a 12 v power outlet for a cool box.
This forum and people like you are a fountain of knowledge.
I have already learned from the links you sent me.

 

[Paul Binding]

Sorry Paynewright it was dell massive that sent me the links.

Happy days, so what are you going to spend your extra wad on now????

 

[Dellmassive]

not sure exactly on yours : @Paul Binding

but looking at the pick . . . you have one fat cable feeding the battery ( from the SCR).

then two thinner cables coming off the battery . . .

on my PV (Panel Van) i had one , thinner cable comming off the battery.

that was feeding the upper dash top 12v power socket . . . via a 15A fuse on the carrier under the seat. ( the lower dash 12v socket was fed from the starterbattery)

so assuming yours is the same . . . im not sure what the second feed is for ?

 

[Paul Binding]

Plenty of overs things in the pipe line, suede headliner,with downlighters, seat upgrade to recalls plus leather and alcantara retrim, ovano bed system, new wheels. The list goes on and this forum doesn’t help either seeing what other people have done.

I totalled up the spend for my wish list and at the last count is was £7.5K. And that Is on top of the wads I have spent on Floyd already in 5 months.
You gotta love it though.

All I found under my seat was some old chips and a hair band, didn’t fancy trying the chips and the hair band totally useless to me

Other cable might be towbar, judging by the additional fuses

 

[Paul Binding]

Why would a tow bar be connected to a leisure battery? I have an aux heater so it could well be for that

Because locating the fuses under the seat makes things easier and 13 pin sockets contain more than just the lights. If you have an aux heater then that will be on the leisure battery also.
