Low Voltage Cut Off Recommendations | DIY Solar Power Forum
Buy 2x35A low voltage cut offs and put one on the power to the trailer and 1 on the power to my new distribution block. Inverter would not be covered, but most have built in protection anyway. The best option I can find is "Powerwerx Compact Low Voltage Disconnect (LVD) Battery Guard 35A" for $85, but that seems a little pricy if I''m going to buy 2.

6 FAQs about [How to cut off the power of lead-acid battery in conversion equipment]
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 if a battery has a cut-off voltage?
This is especially apparent at cold temperatures and in cells with high internal resistance. These batteries may still have ample capacity left after the cutoff; discharging them with a battery analyzer at a moderate load will often give a residual capacity of 30 percent. Figure 1 illustrates the cut-off voltage graphically.
How much battery capacity is left after a battery cutoff?
These batteries may still have ample capacity left after the cutoff; discharging them with a battery analyzer at a moderate load will often give a residual capacity of 30 percent. Figure 1 illustrates the cut-off voltage graphically. Portable devices do not utilize all available battery power and leave some energy behind.
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.
