I've been running a 100a/h LifePo4 for just over 5 years now, its been used and abused and still as good as the day I bought it. I used to charge it via a Redarc BCDC-1225-LV as back when I bought it there was no such thing as a lithium specific DC charger. The Redarc on the Gel profile was good enough for just on 5 years, but I had to constantly reboot it to force it into boost mode to give the battery a charge up to 14.6v. I've recently changed over to an Enerdrive EN3DC40+ charger, this gives me up to 50 amps of charge and gets the battery up to full much quicker than the old redarc. After a full charge, the enerdrive drops back to 13.5 volts and enters power supply mode, detecting loads on the battery and responding accordingly. The Enerdive also has a lithium specific charge profile and user selectable charge voltages etc, I highly recommend this unit based on my limited experience so far with it.
I can run my battery down to 80% DOD with no problems and it is enough for my needs, powering a 90 litre dual zone fridge and lighting etc. The lifepo4 will take every amp I can throw at it when charging. I bought mine from EV power in WA, along with their cell management system, called BCUPPAK-4. The battery weighs 14 kg's and lives in the back beside the drawers. I also have additional HV/LV shutoffs as a backup in case the battery management system fails. It was an expensive setup when I first went down this path, but its proved it's worth and I'd never use anything else now. The battery and cell management cost me $1100 back then, additional components, charger/victron BMV-702 etc, set me back another grand.
This was my set up in a previous vehicle, where I made a set of drawers with a cavity in front for the battery/charger/distribution block/compressor etc. I've gone a different route with the patrol and it's tucked away beside the drawers.
