Finally changed the set point on the low voltage disconnect to address greater voltage drop on the accessory battery from the cold. 🔋

It was so easy to do, beats having to either start the truck or hit the reset switch constantly in the cold.

Now I don’t like to abuse my batteries but disconnecting a load at 11.9 volts in the cold rather than 12.1 volts in the summer isn’t the biggest thing ever. Probably it’s still about the same level of discharge as the summer.

It’s easy enough to change that after I’m done winter camping this week I’ll reset it to 12.1 volts. I’ll have to keep this in mind for the future.
