Siemens
The SI unit of conductance, the reciprocal of the ohm. Electrolyte conductivity is quoted in millisiemens per centimetre; a good liquid electrolyte reaches about 10 mS/cm at room temperature. [1]

Units and electrical basics: an example situation
10 A for 30 min transfers 5 Ah. At constant 3.6 V this is 18 Wh; varying voltage requires integration.
Read Siemens alongside Ionic conductivity in this context. How readily an electrolyte carries ions, in siemens per centimetre. Liquid carbonate electrolytes reach about 10 mS/cm at room temperature; the best sulfide solid electrolytes match that, while polymers fall far short unless heated.
Use in Lemonergy
Use consistent units and cell/pack basis.
This is a reference concept. No executable Lemonergy block has been verified for this term.
