Thanks Jerry for your response.
Now, there are Low Voltage Disconnect circuits that I could add that
would break the circuit at a set voltage. But the disconnect voltage on
most of them are likely set for use with PbSO4 batteries.
-What voltage would be a good disconnect voltage set point for that 12V
Li-ion drop in battery? What voltage would prevent draining the Li-ion
battery too low causing damage?
