As the title says, can anyone tell me the maximum charging current I can put through the 12S socket.
I've tried a search but can't pin down any info on this Morris Dancers: Drinkers with A Dance Problem

10 amps is as high as I would go.

Yes I also (have to) regularly top up my (very expensive off road milk float) D4 via the 12S socket using CTEK MXS10 2010 D4 HSE Ipanema Sand on GY DTs (was on GG ATs)

Have you looked at why you need to charge so regularly?

I think it's probably the way it gets used. Long journeys (2hrs+) are infrequent - say once a fortnight, medium journeys (around 1hr) twice a week, short ones 3 times. The battery is a Bosch AGM about 15 months old. I have a (v cheap) voltmeter which shows great variations (12.3 to 14.7) and the FBH will trigger 'low battery - start engine' message even after 12hrs on charge. My indie can't find anything wrong. So I just charge regularly..... Grateful any ideas, of course. 2010 D4 HSE Ipanema Sand on GY DTs (was on GG ATs)

Sounds like a Battery Monitoring System issue; quite common on the early D4s.

Thanks Robbie - any guidance I should give my indie or would I be best taking it to a dealer please? (It is a PITA because it's a great car otherwise )2010 D4 HSE Ipanema Sand on GY DTs (was on GG ATs)

An indy with access to JLR support or a main dealer will be able to see if you have latest BCM revision installed. There were quite a few tech bulletins on this subject in the early days of the D4. You could check for a current drain yourself but presumably this has been looked for before.Land Rover - Turning Drivers into Mechanics Since 1948

Will book it into dealers next week but in the meantime....charged it up overnight, Ctek showing fully charged this am. Started fine and showed 14.7 (or near) all the time for 1 hour run. Started up to return home after 3.5 hr delay (nothing electric on and locked down at access height) - voltmeter showed 12.1 to 12.7 all the way home. Is that normal please?2010 D4 HSE Ipanema Sand on GY DTs (was on GG ATs)

That voltage is a bit too low. Your really should be seeing something higher from the alternator and the irksome BMS.
