Get a mate to listen whilst you tap a charger on & off the starter battery contacts. Its quite a heavy duty relay so can be heard clicking in & out quite plainly.
Thanks both for taking the time to reply. Attached are some pics with battery removed. Not tried the relay click test yet. Could the VSR be the small square box with "100" marked on. I was expecting something a little bigger. Currently located in the fuse rack under the seat.

The socket that the relay sits un, has all the connections you need - alternator in, leisure battery out, ignition live, you can buy an identical relay for peanuts and gut it to make a plug for your B2B.
@travelvolts makes a plug-n-play loom for that factory OEM setup:

i had the same relay setup, 100A relay, 80A fuse etc etc.
i cut the relay holder and fuse out and wired in my own DC-DC charger (Redarc from @travelvolts) at the time.

Hello possibly already been covered but I can't find it and I'm sure it's relevant.
I have the factory fitted 70ah leisure battery under my passenger seat and would like to upgrade it to a 130ah. The original is a agm. The battery that I would replace it with isn't agm. Will the smart charger be okay with this? Does it need programming in. If I wanted to add solar do I need the dc dc charger thing that was posted a above? I'm rather confused with it all.
Thanks in advance for any help.
Cheers. Mark

what battery did you want to swap it for?
if its the OEM setup then it will be the SCR/ split charge relay . . .
the starter and leisure need to be same chemistry in this arrangement. AGM/AGM AGM/EFB EFB/EFB.
you will need to fit a smart dc-dc charger to do the job properly.
post some pics of what you have.

this is the current leisure battery. My starter battery is original factory spec however it has been replaced twice. The original Moll failed and it's now on a Varta. This the battery that I was planning on swapping it for 12v 130ah Leisure Battery High Power Deep Cycle 4yr Warranty Caravan Campervan | eBay.Could you possibly show me a link for the smart charger that you said about.
Cheers. Mark
@Mark Salmon
you will fry that battery and boil it dry without fitting a smart dc-dc charger.
that battery is an old style "SLA deep cycle" - which has lesser performance than the EFB or AGM battery. (its not designed for stop start cars or vans)
the stop/start and regen from the T6 will put 15v across that battery.
post some pics of your split charge setup?
To use that battery you need to fit a DC-DC charger . . . .

if you are having long term battery issues . . . look at fitting some dash solar to keep the batterys topped up while the van is sitting idel for long periods.

Thanks for the reply. So if I bought a larger capacity agm battery I could swap it without the need of a smart charger?
The split charge system I have now is factory spec so I have no idea where it is. Probably buried in the dash somewhere?

If the battery is AGM then yes - As AGM / EFB is suitable for stop start.
up to the max size you can fit under the seat.

the OEM split charge is normally under the seat bench . . .
and is a 80/100A Relay and a LARGE fuse . .
this was my setup from MY18 panel van.

the 110ah XTREME battery is popular:

The oem split charge and smart alternator (assuming that's what you have) do some rather unpleasant things to your leisure battery. Inter alia your battery will usually be charged to about 80%. If your budget stretches you'll most likely be far better off with a smaller battery that is fully charged by a decent b2b charger.
But to answer your question: if you have the same chemistry starter and leisure batteries (and preferably from the same manufacturer) that should work.

Okay I think it's starting to make sense.
So when the van is running the battery's (starter and aux) are effectively connected in parallel hence why they need to be the same chemistry?
And would then in theory need to be the same size, age and ideally manufacturer?
By using a b2b charger or DC DC charger I can then use whatever leisure battery I want as the two batteries are then charged separately?
So the oem leisure battery isn't really a great set up although it does save me some effort of running the cables.
Basically what I am trying to achieve is I would like to have the odd night away in the van and charge my ebike from the leisure battery. It would only be 1 charge cycle per evening spent and would most likely be lots of driving in between so I think a 110ah battery should be fine.

Have a look at the dc-dc charger thead.
Look at the 20A plus versions, which would be best for a 110ah leisure battery.
The CTEK and Renogy are popular.
As are the victron orion and Redarc unit.
Look for one with a solar input if you want to add some mobile solar at a later date.
