$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.
Learn MoreThe acceptable cell voltage difference for LiFePO4 is 0.1V. You will only reach this level when the battery is either fully charged or fully discharged. This is because a LiFePO4 voltage curve is flat in the …
Learn MoreLiFePO4 cells have a nominal voltage of 3.2V, much higher than the 2V for lead acid batteries. This higher stack voltage means less relative change as the battery discharges. For example, a 12V LiFePO4 battery may go from 14.4V fully charged to 12.8V near empty, a change of 12%. A 12V lead acid battery goes from 12.6V to 10.5V, a …

Learn MoreThe calculation of the characteristic diagram is essential for discharging. Lead-acid batteries show a characteristic with continuously decreasing voltage when discharged with constant current. The higher the discharge current, the greater the voltage drop. Figure 1 shows the modeled discharge profile for a 600 Ah cell loaded with varying power.
Learn MoreReading battery discharge curves involves interpreting the voltage versus time graph generated during the discharge process. Typically, the curve starts at the battery''s fully charged voltage and gradually declines as the battery discharges. ... approximately 1.75V/cell for lead-acid batteries, 1.0V/cell for NiCd/NiMH batteries, and …
Learn MoreThe voltage ranges for a LiFePO4 battery at different states of charge are as follows: at 30% state of charge, the voltage range is between 3.20V and 3.25V; at 20% state of charge, the voltage range is between 3.10V and 3.20V; at 10% state of charge, the voltage range is between 2.90V and 3.00V; and at 0% state of charge, the voltage range …
Learn MoreThe acceptable cell voltage difference for LiFePO4 is 0.1V. You will only reach this level when the battery is either fully charged or fully discharged.
