They're literally a few quid on Amazon although I think myself and @Drive Wayne might have a couple of bars spare!Good idea. Got any copper spare

Can you wait until SpringFest Jon? I'm convinced your Fairy charm helped us out on the way back from Skye!
As above, there isn't enough space..
But as above @TallPaul_S made a bracket, but you need to be 100% is safe,secure and insulated.
Or just a more traditional MEGA fuse and fuse block...(Much bigger than MIDI)
I've gone for a twin MEGA fuse box connected to the battery
One 400A MEGA for the inverter
And
One 150A MEGA that supplies the MIDI sub fuse box..... And off that a ATC sub,sub fuse box for all the small circuits
12vP also do a nice combination MEGA and MIDI FBox, but it's OOS..... ATM.

You can find an earthing point in the same location under the drivers seat.
Ordered....
Im going to use one to bridge out one side of the mega fuse box to make one input with twin fused outputs..
I used the seat base bolt, with the paint ground off.
Or you can drill and nut and bolt to the seat base.
Or you can drill and rivnut to the B pillar.
Or you can drop through the floor grommet and drill and bolt into the lower chassis rail.
Or you can go a bit further back and drill and bolt, in the framework behind the first panel in the back just behind the d pillar at a low level.
Or you could just drill the floor and nut and bolt there, but that will mean getting up under all the trim panels off your tank or exhaust etc etc so that's a pain.
...
Because my new inverter cables are so fat and beefy...
I think I will be drilling and nut & bolt (with serrated washers) to the closest inner piece of chassis framework I can so that will most likely be behind the panel, that is behind the B pillar so basically right next to the inverter. Assuming I do place it there.
My main battery Meg chassis connection will be the seatbase bolts.... Again sand it down and make clean for a good connection..... Or I will take the feed to the base of the B pillar and drill and nut and bolt and no connection onto fresh body work.

Will bear that in mind.
Thanks. Lots to decide between.
Factory Gnd under passenger seat can be shortened and still used for the original factory connections. I did this and used a lower profile but too.
I also used one of the seat base mounting studs for my main Gnd on both passenger and drivers side. It requires some preparation to do it properly. I did a how to thread:

Just installed my Roamer Seatbase4 battery into the double passenger seat. New Victron IP22 charger and Orion XS DC-DC charger added to my existing Victron mppt charger. I had the factory fitted utility battery so just used the live feed and the black engine on signal cable that was connected the the SCR.

Del, can I just ask about cable size that you used to connect both batteries in parallel under the twin seats please.
How did you run the cables?
I am going to be doing similar but only with 100ah lifepo under each seat (as thats all I have), just unsure on the cable layout.
Thanks Adam

I used a 70mm2 for the POS cable.
I used a 70mm2 for the NEG cable direct down to the seat base bolt ... And sanded away all the paint from the four corners.
Because the 70mm2 cable was so fat, and the driver's seat base already so congested I decided to run the POS direct to the Inverter as it could take twin 90mm2.(Via a fuse)........you can also go along the carpet under the join between the front and rear carpet.
But for you....
You can go between the seat base under the carpet., I used a 20mm plastic copex as protection for the cable.

Adding a second 230ah ROAMER 230SBG4
@RoamerBatteries
.
it finally arrived. - this one is going under the passenger seat. . .
a quick charge up with the 100A charger. . . . so the two batterys can be joined.
always make sure BOTH batterys are 100% full before joining together.
a quick 77A charge lol.
this is the original one,
and this is the second one,
combined we get 460ah of battery bank.
.
the twin battery bank worked a treat...

Do your batteries turn on when your engine is on with the DC-DC connected? I normally leave my battery off but since installing a DC-DC every time i turn on the engine it automatically turns on the roamer as its receiving charge and turns the fridge on!
my batterys are all on 24/7
If its powered off using the button on the case then applying a charge to the terminals will wake it up. If you want your system to stay off, you need to externally isolate the battery (to be fair you should have a battery isolation switch and a solar isolator anyway).
