Split Charging - VSR - Routing cables

[ant_thomas]

I'm about to embark on a Berlingo Camper conversion - 64 plate Enterprise Van.
Part of the plan is to put in a leisure battery with solar panel, but I also want to use the alternator to charge via a VSR to create a split charging system.

At the very least I want to run the cables from the engine bay to the rear as one of my first jobs so I have them in place for when I want to get the split charge system running.

What's the best way and route to run two suitable gauge cables from the starter battery to the back?
Is there a preferred or obvious route through the cabin area? Around the sides? Under the centre/middle?

The leisure battery will likely be located in the centre line of the van close to the seats.

How do you mean it will have Cambus electrics?

The VSR I'm looking at is a very simple unit that just triggers above and below and certain voltage. No mention of Cambus or anything remote intelligent.

A 64 plate won't have smart alternator. I took my split charge from the positive battery post, into the fuse, into the maypole voltage sensing relay and off down under the passenger seat to my leisure battery.

Exactly as BerlingoAndy.
Did this without any problems.
You can see all the details with photos in my thread on this forum.
Apologies for it being a long thread.

My Berlingo is a 61 plate, I put a smart split charger from my trailer place, cost me £30 (30ah one) charges my batterys fine max out put is 14.3amp, but it is only 30amp slow to charge batterys, took it off the terminals next to the battery.

I'm back onto this after seeing my solar panel struggle to keep the battery full during winter (no surprise).

Is it possible to take an ignition feed without running cables from under the bonnet?
Wondering if it was possible to tap off the 12V cigarette socket in the back of the van - would it be safe to use this as the charging feed?

Or are there any ignition + permanent cables accessible in the back?

Plan is to use one of the Maypole relays - TEC2?

The B9 versions have a permanent live feed for the trailer sockets on the rear left side, there are some posts about putting the fuse in the engine fuse box to activate the trailer feed.
I'm not sure what size cable is needed to charge a leisure battery though?

this what i used.......does not effect canbus system......

Thanks for the advice. TEC2 arrived today so I'll have a look in the back.
In theory it should only need a trickle/top up but I'll cable accordingly.

Does anyone have any instructions or a video on how to remove that rear left side plastic cover to access the rear electrics? Doesn't seem simple without breaking it.
