Looks like my BMS has finally finished adjusting to the new capacity:
Sadly it seems I'm not going to hit the initial value (read from the salvage vehicle's BMS) of 58.69AH. Still quite happy with the ~60 miles of range I'm getting now. Still shows 5 bars on the dash, not sure when/if that will update.
My car was down to 10 bars before I dropped in a 12 bar battery a year ago. The bars have not returned despite LeafSpy having shown the SOH gradually recover to 90%. (It has since gradually ebbed to 87%)
