Default Redarc BCDC1225?

Hi All

Look to install a dual battery system in my 2012 pb Challenger. Going for a deep cycle under the bonnet and wondering if the Rearc BCDC1225 will be any good?

Mainly looking to keep the fridge running on day trips. But also 3-4 day camping trips (not as often as I would like atm lol)

I have the 40amp redarc. No probs. Camped for 3 weeks in jan driving every 3-4days.
Just make sure you buy the right voltage charger.

It depends on the chemistry of the deep cycle. If it's a std wet acid battery you can get away with good wiring (at least 6 b&s) and a vsr.
If different chemistry then a dcdc charger like the one u mentioned is a good idea. If u can afford it go for the 40amp version so it can charge faster.
Make sure the one u get has the solar mppt module

anyone know if the alternator on the PB is a smart alternator or standard? What voltage model of redarc should I be getting then?

Not sure about the alternator but the system is 12V (the other option is for 24V systems)

Stick with similar chemistry of battery and just use a Redarc SBi12 isolator. Heaps cheaper and will do all you need. I spent ages researching and an very happy with the setup. It's ability to quickly and easily parallel to two batteries got me back to town when my alternator died in the stinking heat!

Interesting Poita, I have the the SBI12 unit as fitted by ARB with their 2nd Battery tray & Yellow top deep cycle 18 months ago. Recently the Yellow top failed and was replaced under warranty. I was puzzled by the ARB salesman who said I should have the BCDC charger instead, they originally fitted it. I asked him to explain the difference, but he was unsuccessful. It has worked fine so far running a 40L engel in the car 24/7 and an Anderson feed to caravan when on the road.

So today I organised a rental campervan and the hirer stated that vehicles with a BCDC fitted do not fair well with the camper that has a BCDC fitted.

I am not the most competent amateur auto sparky, so am easily confused.

It's a std alternator and you will get voltages around 14.4 all the time, higher with the ac turned off.
My car has two identical optima d34 yellow tops under the bonnet and a intervolt variable vsr connected by 2 b&s cables.
I run a 1980's vintage 40l Engel 24/7 and my daily drive to work is about 20 mins each way. The batteries are charged to about 90% in that time.
Once a month I put a 240v 7 stage charger on the batteries and get them topped up.
The intervolt is set to disconnect at 12.2v so the two batteries share the load for quite a while like the traxcide setup. It is rated at 100 amps continuous load and combined with the extra thick cables ensures maximum charge goes into the batteries in the shortest time.
If you were to put the battery in the rear or on the trailer then I would agree with the need for the bcdc charger.

I think arb et al are pushing the bcdc chargers because they make more money from them, and red arc tells them to push them. It's also easier for them to upsell you to the $1500 battery management system.

I am going to get my 2 batt system hooked soon, and my sparky said the SBI12 is all I need.
