The general consensus is "don't do it".
Lithium is fine for aux, but not starter.
It's been a while since I bothered you all about lithium batteries. This time I'm interested in feasibility of replacing my wet cranking battery and AGM auxiliary battery with a single lithium in the old 300Tdi Defender. Can it be done, do I need to change alternator (or anything else), and if so how can I protect the battery from discharging too much to start the vehicle?

The idea of using an auxillary battery to power various things (fridges, lights etc.) when the engine isn't running is to protect the cranking battery from being depleated so that it can start the engine.
Running everything from a single battery regardless of its size/type is a recipe for disaster.
Stick with the cranking battery AND and auxillary battery setup

There is another company that does cranking lithium batteries but I cant remember the name.Think they were WA based as well.
They arent CHEAP but if you get there daily emails they,ll let you know when there on special.
For a 300tdi I,d go for a normal battery and if you go camping then get a lithium for the fridge,lights etc.

Have a chat to DCS……I think these guys are the only ones doing lithium starters.
Those that are running lithium starters still run a second lithium for AUX.
Stop being tight and sort your slide on out first……for the times you’re disconnected from the 130.

Mate, it's really simple - stick a Lithium in for the aux stuff - you won't regret it, then ditch the cranking battery and strap a crank handle to the bull bar.
If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.
I run Lithium batteries in one of my bikes & a Polaris 4x4 .
Benefits : Light weight & holds charge for a long time - real benefit when the Polaris only gets used every 6-12 months.
When the batteries die in my other bikes will be switching over to Lithium
Disadvantages : Cost . May need a different charger to recharge if they do go flat
A mate does the DCS lithium installs,they have literally done hundreds with no issues,under bonnet,on many vehicles.
The 100Amp is generally slightly larger than a wet cell 100 Amp,so is difficult to fit in some vehicles.
The Jap brigade are the usual customers,and two fit easily under the LC200 bonnet.
