2021 GXL Auxiliary Battery Tray?

Hi All

Does anyone know if ARB still does an auxiliary tray with built in Redarc SB12 mount?

I remember using one for my 2013 150 and am looking for something similar for the 2021 model but cant seem to find anything online?

Any other options?

Cheers

Craig

I had my 2012 with the aux under the bonnet and have switched to aux in cargo bay for the new 2021 rig. Having replaced it twice on the last car, and probably near enough to due now, I figured mounting a LiFePO4 in the cargo bay may work out cheaper, and more useable Ah. Early days but does seem to be working fine after setup.

would you put a LiFePO4 under the bonnet or are they likely to fail due to the heat under there?

Most LiFePO4 have a lower ability than AGM to handle heat, according to specs I have read.
I used SBI12 to run power to the camper but the Lithium charges via separate DCDC charger.
