Main Battery Upgrade to Lithium

[George Perry - MB]

I got a different form factor to work in my 2012 LR4.
But charging profiles with OEM alternator is problematic.
Need technical advice, please.
Local mechanics not helpful. ChatGPT offers a 250A high-output Alternator from Nations - but waiting on feedback from bolting and fitting. Wakespeed WS500 Pro Alternator Regulator?
Went from a 94R/H7 to GRP 24 DL+12V-135Ah DP.

The charging profiles are completely different. Long story short, you can't do that.

However, you can add a lithium battery as a secondary battery with a dc-dc charger. Lithium batteries are sensitive to temperature as well, so be aware. Heat and freezing temps **** lithiums. Most people have their lithium batteries somewhere in the cab, doesn't matter what kind of car, truck, suv, etc.

Agreed. There's a reason pretty much nobody use Lifepo4 as a starter. Just get an H8 AGM from Costco and move on to better stuff! and yeah, add a dc/dc and put a 100ah lithium in the truck.
