House Battery Charge Question
I have a house bank with two 12 volt batteries in parallel. I read that I should not let them fall below 50% charge when boondocking, but I forgot how to calculate what a 50% charge with this setup ca...

Temperature and battery manufacturer all affect the full charge open circuit voltage of a battery. Some commonly available batteries are full charged at 12.65V at 80F while others are 13.1V.
Another key is that this method of estimating state of charge only works when the battery has no load and hasn’t had a heavy load on it or been on a charger for a while in order to allow the electrolyte to mix and surface charge to dissipate.
You need a chart from the battery manufacturer that has temperature compensation information and open circuit voltage vs. state of charge.
