LFP chemistry: readings taken at 99% SOC. SOC near 100% — highest accuracy window for LFP SOH calculation.

Recommendations

  • 1

    Battery health is excellent. Continue normal charging habits.

  • 2

    LFP battery: charging to 100% regularly is recommended (unlike NMC). Full charges help balance cells.
