On the charts / graphs my battery is presently showing state of charge 15% remaining ......
Is that:
15% of its maximum capacity when new (11.52kWh)
15% of its maximum usable capacity when new (10.36kWh)
or 15 % of its present usable capacity (after 6 months use it reports 97% health)

It will show 15% of the capacity of the battery after the SoH has been taken off as reported by the 'Remaining energy' in the App.

So 11.52 kWh x 0.97% SoH = 11.17 kWh at BMS reported 100% SoC
1.12 kWh when BMS reports 10% SoC aka 'Empty'

So at 15% SoC, it will report 1.68 kWh as remaining energy
Now useable energy at 15% will be 1.68 kWh minus the 1.12 kWh 'empty' 10% = 0.56 kWh you can actually draw out and use.

thanks
