Lithium with a traxide system.

Can the SC-80 charge all of this? OKA only has a dumb two wire alternator, and an MPPT solar regulator. Currently the two systems are independent, but that means that the house batteries only charge when it’s sunny.
if I can do this could you perhaps give me a rough wiring diagram ?

The best setup in your vehicle would be a Lead Acid cranking battery, then the SC80 wired between the cranking battery and any number of lithium batteries.
As long as the MPPT is set up for lithium battery charging, it could simply be connected to any one of the lithium batteries and all the batteries, including the cranking battery, would be charged by the solar panels.

I have no idea whether these are any good or not as I have had no experience with them.

The specs are not shown but as they are a cranking battery, charging currents should not be a problem.

Is this the one you mean? V-LFP-12-100S Fusion Lithium 12V Deep Cycle Battery - Superstart Batteries

The max charge current is shown as 100A, although it says it is a Fusion battery - not an SSB branded.

No price which is a give away that it's more than what I'd want to pay.

Yeah, well the 200 is $1900 from battery zone. Can’t find the 100 on the site.

V-LFP-12-200 Fusion Lithium 12V Deep Cycle Battery | Battery Zone

This is the range of SSB lithium starting batteries. I don’t see anywhere where they say suits under bonnet use though.

The V-LFP-12-100S Fusion Lithium 12V Deep Cycle Battery brochure says:

• Can be charged with standard 3-Stage AGM smart charges and alternators

Now, I have Tim's Traxide setup with a US160 in a D4. Does this mean I can replace the SSB HVT-50D AGM with the LFP-12 and all will work OK?

FWIW,ARB now have a slimline, Lithium battery with built in DC/DC charger,etc,designed to be mounted in the rear of a vehicle.

Although it is pretty expensive.

From what Tim has said yes, as long as the battery/bms can handle 100a charging. Main issue will be engine bay heat unless you can overcome that somehow.

I need something that will fit in the aux compartment so i think my best option is to get one that can handle 100a charge and take the cells and bms out of the case since they all have lots of packing and make my own if get an empty case and retro fit.
