A new one for me....

The cables are tight and look brand new. The fsiblink is on the negative or the positive? I checked the negative and there is no resistance between the battery pole and the earth connection at the end of the cable so I assume it is OK. Could a bad contact at positive cause this? By 'bad' I mean a slight looseness?

No resistance means nothing as a poor connection can conduct fine until under actual load. I had a similar issue with my fuel pump, got a 12v reading on my meter all day long but pump would not run. Finally fond a very corroded wire barely hanging onto life. Basically enough to pass a voltage rating, not enough to handle the amperage. Resistance works the same way of course, so just keep that in mind.
So looking at your battery....
On the positive lead, remove it and that black box below pull up and out. Take it apart and replace/insect that fuse. They can fail internally. 400 amps I believe. But check for corrosion, I had some corrosion issues on mine at one point. But what is that wire for?
On teh negative lead... what the heck is that attached? Kinda looks like the delivery cutout that the dealer is suppose to remove before selling. I have not seen anything like that before personally. But whatever it is, could be disconnecting the battery ground randomly. That may not seem like a big deal when running, but it certainly is as the battery itself acts a bit like a capacitor on the power system stabilizing/smoothing alternator output. So when disconnecting/connecting a battery on a running car can cause weird stuff.

COSitsWORTHit - do you have sensor rods installed? If so, that is why that happened. The system has no programing protocols that would generate a code even is slammed, it would just air up. But as we know, rods pushing the sensors out of range, past their limits. So the only way to get lift is to jack it up so the sensors read again and the system again knows where stuff is.

Very weird. Both the explosive disconnect and battery monitor only show up as equip in Rang Rovers and the LR4, nothing in the LR3 beyond the transit relay - which after looking over the docs appears to not be what that is on the negative post and is indeed a monitor. Your setup must also mean you have a secondary positive post for jumping the vehicle as attaching a positive jump lead to the positive post of the battery can set off the disconnect charge.
Interesting read about charging the battery and why you can not use the negative post.
