Hello All,
As a result of a less than satisfactory performance by several different cheap battery low voltage cut-outs I am looking at the Redarc SV12 adjustable voltage cut-out.
Has anyone had experience with this unit?
I would appreciate all input, good or bad.
Cheers, Tom

Hi Tom,
It is actually a Redarc VS12 voltage sensing relay. I have one on my thermoelectric bottle cooler to protect the battery from over-discharge. It is well constructed, as are all Redarc products, and works well.

Cheers

A few more details please.

Is this cutout to be installed between two or more car batteries to isolate th crank etc.

Or is it to be used to switch power off to an accessory, such as a fridge if battery voltage gets too low, in order not to flatten the battery?

The VS-12 is intended to disconnect a load when the battery voltage reaches a low set value so as to protect the battery from over-discharge. Its contacts are rated at 10amp.

Use a Redarc SBI-12 Isolator to allow simultaneous charging but separation with engine stopped to protect the cranking battery from discharge. Its contacts are rated at 100 amp.

Google 'Redarc' for more information.

Cheers

Tom try these.

Powertech MS6120

Thanks Allan. I know. I was just asking Tom what he wanted.

Just in case he had made an error in typing.

We have three batteries under the bonnet. One for cranking and two others for auxiliary stuff like lighting, radios and the two fridges we carry. We have the 200 amp Redarc isolator installed.

Before any isolating and splitting was installed we used the Powertechs very successfully to monitor the voltage and cut it off to the fridges when it got low. We needed more time for the fridges so we installed a third battery to give us at least 30 hours run for the fridges.

Sorry people.

I was rushed away.

Tom

You should be fine with the Redarc SB12 stuff. But you may want to try the cheaper Powertech one first. It successfully shut the power off before the batteries were discharged to a point where the motor would not start. We ran one on each fridge in the back for three years without a hitch. Put a third battery in for more run time and a big isolator to be able to use the three batteries for winching as well as starting.

Sorry but I did not get back to my original post to fix it. I just had time to hit the submit button.

Cheers mate

Sorry PJR, I got confused and thought it was Tom asking for more info.

You got confused! (chuckle) No worries

Look at the mess a cat with a mouse in it's mouth made to mine.

Still; I think Tom got the message.

Hi Tom

We do a 60A unit that is adjustable.

Here are the specs:
