Fogstar under seat batteries - will they fit Ducato series 9 passenger AND driver sides?

[Matt_e]

I am looking to swap a pair of 100Ah AGM batteries for (ideally) 2 x 230Ah Fogstar LiFePo4 under seat units. My question - has anyone fitted them in a Ducato (Series 9) with swivel seats? I think the passenger side will be fine (both 100Ah AGM batteries are there already - they are factory supplied NDS units sized to squeeze in there) but I get the impression there are cables running under the drivers side seat so space could be tighter.

(I could swap the NDS 100Ah AGM batteries for NDS 150Ah LiFePo4 of identical size which would be simpler, but these are £1600 EACH and I woudl get 300Ah total whereas the Fogstar's are about £1600 for two and I get 460Ah total)

(I know I will need to look at replacing the MPPT, B2B and EHU chargers - goal is to fit a 3Kw inverter plus better off grid 'range')

Thank you.

I stand to be corrected but the 230's need to be standalone, they cannot be connected together I believe.

But the 300ah fits under the seat perfectly . Check out my drivers seat . The connecting bar between the side rails look like it was designed for this battery

You can connect up to 4 together in parallel but you cannot connect them in series.

It's worth knowing that if you're a paid up subscriber here you can get 10% off from Fogstar and also from Offgrid Power Solutions.

I thought I'd seen a post from RogerIvy where they connected 2 together

Yes I just checked they can be, I'd just misread it

Can I ask what route you took with the cables

The Roamer 230 fits like a glove under my drivers seat, courtesy of RogerIvy, but is a few quid more than the Fogstar.

The Schaudt ELB, Lippert Battery to Battery Booster and Votronic Solar Controller are under the passenger seat, so no spare space there.

Thank you to everyone who responded - now I just need to think about 230ah x 2 vs 300ah x 2

Is there any room left for. B2b under the seat as well?
