At this point, the transistor will turn off too and deactivates the relay which is connected with the battery and the headlights. LVC doesn't work based on resting voltage, so even if your battery was resting at 46-47v after it cut off, LVC might still be the culprit if it dipped down … Generally rated voltage of current single lithium battery is 3.7V and cutoff voltage 2.75V. Try again. Secondly I have been working on designing a low voltage cutoff circuit that cuts out at 17.5V, and can pass up to 20A. Lithium battery cutoff voltage means that it is not suitable to discharge any longer if lithium battery voltage reaches a certain value otherwise, partial capacity of lithium battery will be irreversible or even battery will be seriously damaged. Please make sure that you've entered a valid question. If your car battery voltage is discharged, or has less than 12.4 volts, the power decreases dramatically. A relative voltage cut-off “detects” the battery voltage at plug-in and then the cut-off is a percentage of that voltage.
