Default Dual battery advice

Hello,
Im looking at setting up my dual battery in the NS.
I have taken the isolator out of my NP, a Projecta 150 amp, as well as the ARB battery tray. But i am now thinking of mounting the battery in the third row seat well.
I have bought 8 b&s cable as i was going to run this to the back for the fridge and a merit plug running off a fuse block.
But now as i am thinking about putting the battery in tree back, would that cable be big enough?
Thanks,
Andrew.

I used 8B+S to the rear distribution point in my gen 3. It was fine. The battery was under bonnet though with a VSR.

I run 6b+S to a dcdc and a battery in the rear of the NX and that is fine too.

There is not much difference between 6 and 8 ga. If using a dcdc, I reckon 8ga will be ok, but not if using a VSR.

Just my opinion.....

I run 6 B&S ALL THE WAY FROM STARTER TO CAMPER VIA THE THIRD ROW SEATS AND HAVE 2 X DCDC CHARGERS( ONE IN TUB AND ONE IN CAMPER)...ALL WORK WELL. i HAVE A pROJECTA 25AMP DCDC CHARGER i DONT USE...YOU CAN HAVE IT FOR 100 DOLLARS PLUS POSTAGE....Lot better than the Thunder. It also has a built in MPPT solar regulator.

I think you'll find the 8 B&S to be quite sufficient. I have the 2nd battery under the bonnet but the Intervolt controller in the rear seat well. this means I have two 8 B&S cables running between engine bay and rear seat well. (I know everyone will say this is stupid but it works for me). Anyway, the system works perfectly with no appreciable voltage drop. The controller in the rear means its out of the heat of the engine bay. The battery under the bonnet means I can fit my 40L water tank in the rear seat well.

This chap has some quite good info,

https://www.fridge-and-solar.net/dual_bat.htm

I run 8 B&S for a fridge & my camper has Redarc BCDC1240 (40Amp charger), I run 4B&S for that with 120AMP Anderson plug.

6B&S would be fine for less amperage say 25amps.

Cannot be underestimated how joints & fusing is approached in my opinion. For me it's Mechanical crimp & solder with glue lined heat shrink & bolt down Midi fuses where applicable.

Unsure. I will post it for $120 and include 2 x 50 amp genuine anderson pluigs as well ..for your wiring. You may not need the plugs but use them elsewhere.
Let me know asap as someone else is keen on the unit.
