Hi All
I am installiing a DBS in latest Prado T/D. I have had the hard sell on VSR's from Matson, Redarc TJM, ARB's Smart Solenoid and the Piranha DBE 180S. Can someone out there without a vested interest give me some advice as to whether they all basically do the same job as each other, reliability,service backup robustness etc. Thanks

I've had a Redarc for about 4 yrs. No problems. Keeps the auxillary battery charged and can be used to jump start the vehicle if necessary.

G'day davali

I have a 2004 T/D Prado and had a Rotronics DBS installed in mine @ purchase. Never had a problem whatsover, have run the Engel on super cold for upto 5 days without recharging and vehicle turned over first crank. Few off my mates have installed the same system and have not had any probs either.

Just my two cents worth

I have the Piranha DBE180s+ in my 80 series. Very happy with it, easy installation, has inputs for solar panels and battery monitor.
Also it can run a third battery.
Most importantly it offers surge/spike protection.

The only thing it doesn;t do that some of the others can is jump start but if need be I'm sure running a jump lead from 2nd batt to main batt would be ok.

I also should have mentioned it can run different sized batteries as well.

PS.I do not work for them, but have found them very helpful.

Davali, I am looking at either putting a DBS or deep cycle / self charger on the camper, so I will watch the comments closely and with interest. Mark

Hi Davali,
I have run redarc in all my vehicles, with solar panels fitted as well, I have them setup with the push button on the dash if I ever need to bring batteries together to start vehicle, also have the indicator light on the dash so i know when the start battery is being topped up and when the aux is being charged.
Only ever had a problem with one, I rang up redarc in SA and they sent me a new one, no questions asked.
My thoughts for what there worth with no vested interest.

Cheers with Beers

They all kind of do the same job, but some perhaps better than others.

If you have already bought the Piranha DBS180S, you have bought one of the best "smart" Isolators available.

I have an earlier model DB150S and it has worked well for some 5 years.

One thing Piranha will state. There Isolators will manage any combination (types) of battery installations. Doesn't matter what size there are, or whether they are a mixture of wet cell and AGM.

Not too many manufacturers will state that.

Everyone seems happy with what they got... must say something?

When you look at the principal of operation, they *all* do the same thing. they all compare the batteries' voltages and make a decision to connect or isolate the batteries. in the engine-on state (i.e., ~14 V), batts are connected; engine-off (~12.6 V or less), batts isolate.

they differ in trinkets (solar input, battery monitors, etc) and physical contruction, but fundamentally do the same thing.

ARB, Piranha, Rotronics, Redarc are all good... and all the same. base your buying decision on price, warranty, after sales support, etc. On this basis Redarc is arguably the best.

FWIW, i have an ARB Smart Solenoid. it works well but the Redarc does the same thing for much less $$$.
