Just purchased the Redarc unit for my dual battery set-up. Question. As I installing my 2nd battery in the rear of the vehicle and mounting the redarc very close by. Fed by good gauge wires from main battery. Do I have to connect the blue wire(for vehicle ignition) to a wire that is alive after ignition is on OR can I simply twist the blue wire to the red wire(input from main battery) ? This would save me having to splice or join onto a live wire and the unit will work(in my opinion) when the alternator fires up.

Biggie,
Was going to put one of the 1220's in our slide-on camper, but baulked at it once I read you have to run a ign wire to the blue wire.
Instead purchased a Redarc BMS unit, which gave us MPPT solar, 240v charger and battery isolater. No ign wire needed, but you pay for the privilege. :-((
For long term, reckon you'd be better running the blue wire through to an ign activated source. Don't think it'd need to be too heavy?

The only reason I went with the redarc is because of the "smart" alternator. Always had Toyota before the Pajero. As I said, I will disconnect the aux power point in the rear and plug the redarc into this. Putting battery in rear tub of car as up front there is no room for a 130amp agm battery. The additional Donaldson fuel filter takes up the space when installed. I have solar but have a good regulator so only needed the redarc without solar function.

If people will allow me a slight divergence, I will have a question that I believe is related and please don't let me steal the thread.
We have a dual battery system under the bonnet with a redarc 200 amp isolator between them.
Well actually there is a single crank on one side and two batteries as accessory supply. All three are identical Allrounder 105AH batteries and have kept the
camp, including two Engel fridges, running for three days without any charging.
I noticed the mention of an isolator in the description for the BCDC1220 but I don't think that if accessory current was required to aid cranking, if the crank was flat or faulty, that 30 amp would help much.
Would it be to our advantage to add a BCDC1220 to our setup?
Merry Christmas
