Split charge relay rating has nothing to do with number of batteries.Physically there is only space for a single battery under each of the front seats. You could add a 3rd (2nd leisure) battery under (your) passenger seat (UK drivers seat).
Would be worth checking with an auto electrician if the split charge can cope with an additional battery but shouldn't be an issue.
B to B unit
I don't know about that. The BlueMotion emissions function involves Regenerative Braking.Well my conclusion was that the Cali can't be running a smart alternator due to the split charge system. It certainly doesn't have a B to B unit.

Actually AGM batteries were designed for this purpose, I can understand gel batteries having a problem because expansion is an issue.That is very interesting, especially as it says that smart alternators can be bad for AGM batteries. Maybe I shouldn't be too upset mine is a Lead acid?
A B to B or battery to battery charger is a DC/DC converter.Whats that mean?
I'd second that.Just add the battery. Don't bother trying to charge it. Charge it when you get home.
