Low Battery Voltage Cutoff

[Duoglide1]

We bought an Endless Breeze 12v box fan by Fantastic Fan and use it constantly. No inverter. I believe on low it's 1.3 amp D.C. draw.

I don't want to wake up to a dead battery. We might watch TV for a couple of hours and then sleep with a phone cellphones charging and the fan running.

The LVCO on this el cheapo one is none adjustable. (Although I might open it up and look around.)

This is on a travel trailer so it will not need to start anything. I just don't want to prematurely end its life.

Thanks again!

That is a pretty small battery. It might be worth considering to just put in a bigger one. A size 31 (tall) lifeline GPL is almost double that and might go all night.

I bought a solar charge regulator that you able to cut the flow of current to the load (in my case the inverter) at a set voltage. What I didn’t plan on was that I couldn’t set it any higher that 11.7 volts. I have to pause this project for a bit but will be looking at a better quality battery monitor and charge controller after the holidays.
