The free space next to the auxiliary battery has about these dimensions (16 cm being the free height). It is approximative because of the irregular shape and protrusions.

I don't think the battery compartment is watertight, but the sensible parts are sufficiently above wading height.

It is claimed to be watertight I believe

It will be watertight enough so you can hose out the back (Fieldmasters excepted), and possibly to withstand a deep dunking.

Thank you for the dimensions. Do you thing the space would suit and fit an air compressor?

Are you thinking of the underseat dry stowage ~ only fitted to 5 seat variants and then deleted if the auxiliary battery is optioned?
No, I was under the impression that the whole box was supposed to be waterproof so water couldn’t get to battery and fuses etc unless water comes over the top of the box.

That solves the battery debate. Definitely not AGM or GELL Batteries but EFB enhanced flooded battery 👍🏼
Hmm on a large engine vehicle, built for purpose, I'd have thought they would go for AGM. Will be interesting to see if it is still EFB on the non auxiliary battery vehicle.

Just spoke to aftersales at INEOS and below is the response.

The alternator output is rated at 250Amps.

The vehicle battery​

The battery that powers the Grenadier is a 105Ah EFB Moll battery.
It works as a traditional 12 Volt system with an alternator charging the battery when required.
The Auxiliary battery that is used when optioned is identical to the main vehicle battery and will be wired in parallel to insure that it stays a 12 volt circuit.

EFB - Enhanced Flooded Battery. These batteries are sealed and are not able to be opened to test cells.

The Battery is located in the same position on all variants. Ether under the second row seating or load space floor on the 2 seat utility wagon. Both the seating and floor can be easily lifted up to gain access if required with no need for any tools "the auxiliary battery is located on the opposite side"

Yes, no problem presuming you are lifting the seat to connect the air line, and operate it as such.
Will effect the duty cycle if you operate a single cylinder compressor in the closed space (eg it’ll get hot and shut off repeatedly).
Commonly fit dual compressors behind panels, see photos in earlier thread… noting these achieve a higher duty cycle by a) including cooling; and b) toggling between cylinders as one gets hot.
Not enough room for a twin beneath the seat however.

Good to see that they are all reading off the same script ~ see post #34.

These batteries appear to be vented and being "wet" seem to employ a different definition of "sealed" to that of say an AGM.

Also hard to call the whole underseat area watertight if there's a vent tube running through a hole in the floor.

I’m sure they could seal around a pipe easily enough with a bulkhead fitting🤔

Yep, the second battery (along with the RAI) are the two things not build for my purpose that I would have liked to delete and install a better set up.
I have already bought my 100ah Lifep04 battery and Redarc Bcdc ready to slot into my Fieldmaster that doesn’t come with the RAI.😉

So why did you choose them?
It is easy to start with the Station Wagon and spec it up to what you want

But then it isn’t a trialmaster is it. 😉
I’ll re-engineer what I need given the compromise.
Seal the RAI better and swap out / re-design the battery system and it’s all good.
I can always use a spare battery somewhere.

And a like for like cost comparison had the trialmaster about $750 in front which meant I almost got one of them for free. 😁

Pricing must be very different now.
I configured to the same spec from Wagon, Trial & Field and the difference was $400
