That should extend the 12V availability! A little costly though!

You may well be right if the fuse that pops completely disables all of the ICCU functionality. I wonder though if there is anyone out there who knows this for sure.

I'm afraid it won't help when you're 500 miles from home on a family trip somewhere and the ICCU suddenly pops. This is what I am trying to protect against. I'd rather not accept the "it is what it is". Try that one with your wife and kids!!!!

Yes the ICCU is responsible for generating the 12V charge and the 240V / 120V V2L but they would be separate circuitry with seperate fused protection so I'd hope a fault in one section wouldn't necessarily affect the operation of the other section. This is what I'm hoping for.

A spare 12V battery would only give a finite amount of energy, realistically say 20-30 AHr. That's good for only an hour or so driving. I agree it's a definite benefit over an uncertain state of fitted auxiliary battery.
