<![CDATA[Why BYD Recommends Charging LFP Blade Batteries to 100% Once a Week (BMS Cell Top-Balancing Explained)]]>Unlike NCM (Nickel-Cobalt-Manganese) batteries that prefer an 80% daily limit, BYD's owner manual explicitly recommends charging your LFP Blade Battery to 100% at least once a week.

Why BYD Recommends Charging LFP Blade Batteries to 100% Once a Week (BMS Cell Top-Balancing Explained)

The Engineering Reason:

  • LFP cells have a very flat voltage curve (~3.25V to 3.33V) between 15% and 95% SOC, making coulomb-counting drift slightly over time.
  • At 99%–100% SOC, LFP cell voltage rises sharply to 3.60V–3.65V, allowing the BMS to calibrate exact SOC and bleed-balance all cells to within 5–10 mV of each other!
