Lithium Dual Battery Compartment
TWO BATTERIES, ONE BOX
Side by side, both clamped under one hold-down plate
3MM ALUMINIUM
Powder coated, and it will not rust like a steel box
SEALED, AND VENTED OUTSIDE
A 12mm vent fitting runs a hose to the exterior, so anything the batteries vent leaves the vehicle instead of the cabin
AS/NZS 3001.2:2022
Designed around the standard for electrical work in relocatable vehicles
MADE IN WA
Cut, folded and coated by us, and available as a custom build
The dual version of our sealed lithium compartment, sized for two batteries side by side. It does the same job as the single: a powder-coated 3mm aluminium enclosure that lets lithium live inside a caravan, motorhome, camper or troop carrier, holds the batteries clamped down over corrugations, and vents to the outside of the vehicle rather than into the space you sleep in.
It is fully sealed, with one important condition. A 12mm push-fit vent fitting sits on the top face, and a 12mm hose runs from there to the exterior of the vehicle so anything the batteries vent goes outside. The seal is only as good as the installation — the lid has to be fitted and sealed correctly for the compartment to do its job. Where we supply the compartment on its own rather than fitting it ourselves, that part is in the installer's hands, so it is worth being deliberate about it.
On standards, we would rather be straight with you. The compartment is designed around the requirements of AS/NZS 3001.2:2022, which is the standard covering electrical installations in relocatable vehicles. It does not carry third-party certification, and no enclosure on its own can make an installation compliant — that comes down to the whole install and the person doing it. Wiring and mounting should be carried out by a competent person.
What fits. Two batteries on a 370 x 190 x 245mm case, which means the Amptron BluEdge 200Ah or the Custom Lithium Compact 310Ah. Those two share a case size, so if one fits, the other does, and you can pair them how you like:
Amptron BluEdge 12V 200Ah → · Custom Lithium Compact 310Ah →
Lithium only. Do not put a lead acid, AGM, gel or calcium battery in this compartment. They vent differently and the enclosure is not built for it.
To finish the install you will also need cable, lugs and the vent hose, none of which are in the box:
0 B&S single core battery cable, black and red →
50-8 copper cable lugs →
12mm hose for the vent run → — choose the Black Coil, which is 12mm on the outside and is the size the push-fit fitting takes.
You will also need a polyurethane sealant such as Sikaflex for the lid, which we do not stock.
If neither the single nor the dual suits your build, we make these to order — request a custom battery compartment →
