If so then I don't see any harm in owners with paid batteries doing it.
No extra range is gained since the battery only has whatever capacity it has. The charging circuity will still limit the current flow in/out of the battery and the max/min voltage it allows the battery to reach. Resetting the BMS does nothing except corrupt the firmware that calculates and indicates the available battery capacity.
Well - here is what actually happens.. There are 3 levels of LBC reset, you can reset the capacity bars - clear the battery degradation and clear the charge counter. You are partly correct as in no extra range is given. I was hoping that regenerative braking would be increased but alas this is also unaffected.
There is no corruption in the firmware at all, the GOM and capacity bars will return to normal in time. Some people have said that the LBC is pessimistic regarding the SOH, thus a reset does work for some, alas I cannot corroborate this as I saw no improvement at all.
