+===== lithium SoC =====
+Lithium chemistries have very flat voltage curves, making it  notoriously difficult to gauge SoC by voltage.  In this case [[electrical:12v:battery_monitor|a shunted battery monitor]] is used to count amps as they go in/out.  If the Li battery has connectivity you may be able to read SoC from the internal BMS.
