I just bought the Victron Battery Disconnect BP-65. I have two questions but first a little background on what I don't understand.
I am using a sealed lead acid battery. Everything I read says not to let the battery discharge below 50%.
Looking at the voltages for the depth of discharge for these batteries shows:
12.23 V = 50% Capacity / 50% Discharged
12.11 V = 40% Capacity / 60% Discharged
11.96 V = 30% Capacity / 70% Discharged
11.81 V = 20% Capacity / 80% Discharged
11.70 V = 10% Capacity / 90% Discharged
11.63 V = 0% Capacity / 100% Discharged
The disconnect settings on the Battery Disconnect are:
Display 0 Disconnect 10.5 V
Display 1 Disconnect 10 V
Display 2 Disconnect 9.5 V
Display 3 Disconnect 11.25 V
Display 4 Disconnect 11.5 V
Display 5 Disconnect 10.5 V
Display 6 Disconnect 11.5 V
Display 7 Disconnect 11.8 V
Display 8 Disconnect 12 V
Display 9 Disconnect 10 V
(Note some are the same cutoff but the restart which is not shown is different)
The battery is not supposed to go below 50% discharge which is 12.23 Volts Also, anything below 11.63 shows a completely discharged battery.
Question 1: Why don't any of the selections match the voltage depth of the 50% discharge?
Question 2: What should I set the voltage and why won't that lower voltage kill my battery?
