Neat little 12V low voltage cut off?

Unsure how well everything works but the functions are nice - on paper. Adjustable settings that include when the power returns to the load. Think I will give it a shot with electric fence and camper. Save the batteries.
LED read out consumes some power. No idea how much. https://www.amazon.com/gp/product/B07Y383XML/ref=ox_sc_act_title_1?smid=A36921MXRJULWD&psc=1

I bought a similar one in a different package that goes up to 100V. That allowed being powered by a separate power source. It included an adjustable time delay which I feel is quite important in these applications. Unfortunately, the time delay was less than 1/10th of what was stated. I view all these specifications with caution.

I doubt that everything will work as advertised. I'll be happy if I can program the off and on functionality at the voltage levels I seek.
I have a couple with a 10.5 volt cut off as memory serves. Too low for my tastes.

Just keep a good differential. The moment you disconnect a load, the voltage jumps back up.

Was wondering what the load of a 12" 110dB horn siren is. Guessing 10-15 or so.The achilles heal of a fence alarm? If I don't shut it off that means I am not home. What to do? Would be better if it howls ~ 1/2 the time I guess. Make them wonder a bit.First Bank:16 180 watt Grape Solar with FM80 controller and 3648 Inverter....Fullriver 8D AGM solar batteries.
