Depending on what battery he intends to use will have a big influence on performance.

For example the AMPS 100ah LiPo will do 20a Optimum charge current

Could be:
Cost
Size
Battery capability

On holidays hence late reply to the various questions.

Being in WA anywhere is a long way so I'm on the road sometimes for days on end. I dont use the battery when at home so every trip will give it a little top up. I have the projecta lithium charger. It's 25A, was cheap for name brand, MPPT included and is the recommended charge rate for the battery. It won't take up any space as it's going underfloor where 5 seater tool kit goes, although now I have the battery it's 1cm too tall. Bit of carpet cutting coming up.

One thing i am after is a cheap battery monitor, not a volt meter as I've got them. All models I've seen like victron, enerdrive, ctek are around $300 or more. That's the same price as the charger! Any other options people are using out there?

To answer my own question about a battery monitor I've found this 100A Battery Combo meter monitor with shunt - State of Charge Indicator | Coulometer - AMPTRON - Sustainable Power Solutions, Lithium Batteries, Battery Chargers, Power Monitors, Power Packs, Solar Power
They are located in Perth which is a bonus for me too.

That’s nice. I have a cheapie from AliExpress and while it tells me current out, voltage and power consumed, it can’t tell me inflow and can’t compute current capacity based on inflow and outflow.

That looks good. And at a reasonable price.

Is this to monitor aux or cranking battery performance?
Please keep us updated if you go ahead, interested to see where it will be mounted etc.

You can not actually monitor the cranking battery performance with any meter that is a low side monitor.

You can easily use it on auxiliary batteries of any form, but tampering with the negative on any Land Rover's cranking battery may lead to other problems, and this applies to most new vehicle makes.

Those decides are also plentiful on the net.
