Not sure if this setup is any good for you. I have a 2007 Ducato x250 3.0 and use it every day for my home. 1200w inverter, 2 x 90ah batteries in parallel, bm1 Bluetooth monitor, victron battery protector and a Stirling 60a battery 2battery charger.

I’ve just put a second under my seat

This isn't the best way to connect two batteries. Ideally the load negative should be on one battery and the load positive on the other. This balances both the charging of the batteries and the current draw when under load. Becomes even more important if you have 3 or 4 (or 12 as on a barge I had)

Fortunatly the early 2000s Ducato, has a decent sized space under the passengers side seat which will take another leisure battery.
But can anyone tell me how to connect it up ?
Which terminals do i connect it to, to the existing battery under the drivers seat ?
Does anyone make a wiring kit for this ?

If your still reading. .

Two new wires of suitable gauge.
Connect one from Pos of old to Pos of new battery.
Connect Neg of old to Neg of new battery.
Connecting Pos to Neg will give you 24volts.

If batteries are side by side and no risk of any part of connection or either battery touching earth then no need for fuses.
If old battery is older than maybe 12 months or ever been abused fit two new batteries.

Measure the length of the leads that you need and go to a motor factors and they will make you a set up with battery clamps fitted.

Can’t see it making a massive difference if I’m honest but I bow to your superior knowledge.
I’ll crimp a new end on and lengthen the negative.

I'd suggest you put a battery isolator switch and a big fuse in the positive wire, right next to the batteries, maybe mounted on the seat box.

Right behind the seat is a breaker which is fine. Nothing can fowl the positive or the negative as it happens before it gets there.
