This is a rough guide to correlating at rest battery voltage to the state of charge.
- There is respectable unofficial guidance that this curve varies as the pack ages over its lifetime.
- These figures are determined from some selection of owners with logs, with minimal experimental controls.
Warning: | Your mileage may literally vary! |
