Battery observations with the flight behind them
Follow an identified battery through the logs you have imported. Review available cell measurements, charge and temperature alongside the flight that recorded them.

Read the measurements together
A voltage reading means more when you can also see charge level, temperature and load. Flymetry brings available observations into the same review, with the original log as their source. The fields shown depend on what was recorded and successfully decoded.
Keep history attached to identity
Use the battery serial number where identity is supported. Review the latest observed cycle counter with its date rather than adding cumulative readings across flights. Unresolved pack indices should not silently become a physical battery's history.
Compare only when the data supports it
Battery model, cell count, temperature, charge and load matter when interpreting a difference. Flymetry conditions comparisons on the available evidence and can explain why an observation does not qualify. Missing data stays missing.
Understand what capacity means
BMS-reported full-charge capacity is useful history, but it is the battery management system's estimate. It is not an independent capacity test or a certificate of remaining life. Flymetry does not provide a health score or a fit-to-fly decision.
