Low voltage cut-out?

**Ranga** · 4th January 2010, 07:36 PM

When buying a deep cycle battery off the guys at Springers (12V specialists), they mentioned I shouldn't really let the battery go below 11.6V. So, I'm looking at ways to install an automatic cut-out switch on both my dual-battery and portable battery.

I can get an 11.6V cut-out for my Bushman fridge, but that will only stop the fridge, and not any other appliances such as lights, chargers, laptop powerpacks etc.

I notice Waeco make a 11.6V cut-out switch for their fridges (WAECO mobile solutions) and was wondering if I could adapt that to suit.

I'd planned on inserting it within my portable battery box between the battery and the cigarette lighter socket, and also in my vehicle between the dual-battery and the cigarette lighter socket. Note that I have a Redarc dual-battery switch already in the vehicle, and I'm not sure if this has any low-voltage feature.

Would this work?

pretty sure d.ick smith has low voltage cutout kits.......maybe tim 'traxide' does them

Thanks weeds and I am working on a 30 amp unit at this very time.

Tim(Drivesafe) did a modified SC40 for my Engel,as engels need a low voltage cut out too.Works a treat!!!!

My Waeco CF-110 comes with an inbuilt cutoff selectable to 3 different ranges.
On a dual battery setup, shouldn't it switch if the voltage gets to a pre determined level anyway???? If ignition Is off I assumed they either switch to the main or cutoff completely.......?

I think the Redarc only cuts out the cranking battery once it hits 12.7V?

My Bushman fridge can also cut out at different voltages, but that doesn't protect the battery if I have other devices plugged into it.

Hopefully the Waeco cutout switch can do the job.

Unless the new ones are different I think you will find the 3 position voltage switch is only on the smaller fridges. On the 80L and 110L the three position switch is the power saving switch for differing compressor motor thing speeds.

Ummm, nope. The setting is in the digital display and sets as LO, MED & HI and it's for fridge shutdown as a power saver. Should know, after all, I am looking at mine right now as I get another beer while on holidays and I sell them at work.

The selectable switch at the base is for normal or emergency overide.

This fridge wiring kit from Waeco has a low voltage cut out ( or so the spec says ) and would be rated at a hgher current than the one you linked to above.
It is 6 mm wire so should be OK for what you want.
Also has a switch so you can choose permanent power or ignition switched power.
$119 but you will get one cheaper at Rays/Anaconda etc on sale.
I've wired a copule of these for mates the kit seems well made.
