For those who have added a B2B on a Ducato (or similar) PVC - what route did you take for the cable?
Did you manage to run the cable internally or did you end up dropping out under the van and back up inside?
Our starter battery is in the usual place in the passenger footwell. The original cab floor has padded insulation underneath effectively limiting running a 16mm2 cable under the cab floor fro what I can see.
The leisure battery is under the seat opposite the sliding door (2 forward facing belted seats with a table, both front seats swivel to give you 4 around a table).
Options I can see are either running the cable up behind the dashboard, across behind/under the steering wheel down through the step and past the B-pillar under the hab floor, or dropping down out of an (existing) hole in the engine battery well, running under the van and coming back up under the rear seat - the water tank filler pipe already comes through the side of the van and runs through this space before dropping down through the floor to the underslung tank, but we’d need to make (and seal) new hole for the cable I think.
If it does come to running the cable under the van, I think we’ll need some conduit to protect it, and will need to be wary of the heat from the exhaust.
Lots of posts here about B2B upgrades but no-one I can see has mentioned the exact cable route they took, so interested to see what others have done!
Lastly, I chose 16mm2 cable as this fits directly into the Victron 30A B2B and (depending on final cable run!) should be sufficient for a suitable voltage top over the expected length. However, the converters socket in the B pillar behind the drivers seat has a connection to the vehicle battery, which is designed for powering accessories in the rear of a conversion. It is rated at 50A according to the converters manual. It’s a fairly skinny cable though! Has anyone used this for a 30A B2B installation? Victron recommend the cable is fused at 60A but is there any reason this couldn’t be lower given that it’s a 30A B2B?
