For example, lead-acid batteries have a nominal voltage of 2.0V per cell, while LiFePO4 cells are at 3.2V. Additionally, the fully charged voltage for lead-acid is around 2.4V, unlike the 3.65V common in LiFePO4 cells. This means that a 12V lead-acid battery consists of six cells, while a 12V LiFePO4 uses four cells.

Lead acid battery
A lot depends on discharge current versus battery capacity. If its very light duty (huge battery - low discharge current) then the low voltage disconnect should be set quite high, 11.6v to 12v sounds realistic. If its extreme duty (small battery - massive short term discharge) then you can probably go down to about 10v.

Safe cutoff point for lead acid batteries | DIY Solar Power Forum
Lead acid batteries have high overpotential voltage slump under load so best way to decide when to stop discharge is via a Columb counter. At 0.25 C(A) discharge rate a 12v lead acid will drop from full charge open circuit voltage of 12.7vdc down to 12.0v in about 15-25 minutes of load current.
12v lead acid battery cutoff sketch
Also, if you want the battery to last a while, you should target a 30% or 50% SOC for cut-off, not 0%. Completely discharging a lead acid battery will shorten its life dramatically. If the battery capacity is small, it will have a large internal resistance and the voltage rebound when the load is removed might be pretty big.

6 FAQs about [12V lead-acid battery discharge cut-off]
What is the low battery voltage cutoff in the lead acid?
The Low Battery voltage cutoff in the lead Acid is kept at 10.5 Volts to keep it safe.
What is the cutoff voltage for a lithium battery?
For example, a 12V Tubular lead Acid battery might have an LVC of 10.8V. This means the LVC will disconnect the battery from the Load when the voltage drops to 10.8V. For the lithium battery, this cutoff is at higher voltages as the Lithium battery LifePo4 has a voltage of 12.8 Volts, so the cutoff voltage for a Low battery is 11.2 Volts.
What is a low voltage cutoff circuit?
A low voltage cutoff circuit is an electronic circuit that monitors the voltage of a battery and disconnects the load when the voltage drops below a predetermined threshold. This prevents the battery from being over-discharged, which can lead to reduced performance, shorter lifespan, and even permanent damage.
What does LVC mean on a battery?
The LVC is typically 10% below the battery’s nominal voltage. For example, a 12V Tubular lead Acid battery might have an LVC of 10.8V. This means the LVC will disconnect the battery from the Load when the voltage drops to 10.8V.
What happens when a battery is recharged to a higher voltage?
When the battery is recharged to a second predetermined higher voltage (upper voltage threshold), the relay contact automatically re-closes and power again flows to the load. Both lower and upper voltage thresholds are independently adjustable to the desired voltages.
Why is dynamic cut-off important for LiFePO4 batteries?
Dynamic cut-off is useful for batteries with a high internal resistance. For example OPzV and OPzS; but is less relevant for LiFePO4 batteries because of their low internal-resistance. See how the graph shows a much flatter curve for the charge current vs disconnect voltage.
