sorry I don't have the specific expertise to answer your question but why don't you check with Redarc themselves. I've found their tech guys very helpful.

They also have a forum on the redarc website that you can ask your question directly and the techs provide answers pretty quci.

Cheers Mick

A 100 amp battery that can handle high inrush currents will pull around 60 amps when connected to a charging voltage of around 14.2V and connected via 10mm2 cable.

It will continue to draw over over 40A for 10 minutes as it gradually reduces. You will probably get away with it as the length of cables between the alternator and the van batteries will limit the inrush current somewhat to the van batteries.
