Measuring the SOC on a lithium is no easy task. But there are ways.....

It would seem to me that a battery monitor will measure the SOC of a lithium battery the same way as it does for a lead acid battery. Alternatively, using the BB voltage versus SOC table you can determine the SOC of the lithium battery using a voltmeter to measure the voltage of the lithium battery.

The photos show the voltage and the SOC of my lithium batteries using my Trimetric battery monitor.
