12v voltage based cut out or cut in

Hi all

I am after something that will energise a 12v circuit at a certain voltage or cut out at a certain voltage.

Effectively

I am trying to avoid split charge. I want to be able to run led warnings lights and work lights but if my battery drops to 12.X the circuit is killed to preserve starting capability

I know some highways had this

So my options are to energise at a certain voltage or cut out at a certain voltage but to handle 20-40 amp

☺️

I use a programmable durite 12v battery guard. You can program the cut in and cut out voltages.
Have a look at there link below if its the sort of thing you are after i maybe able to help you out as i have a number of secondhand ones, i have the 100 amp version.
