  Battery shows 13.2V when idle, but once I start my inverter it drops to 12.5V instantly. Normal behavior?

  @Archie Wilson Keine Sorge, LiFePO₄ springt gerne runter, Spannung stabilisiert sich nach ein paar Sekunden unter Last.

  @Archie Wilson 12.5V sofort? Klingt nach zu hoher Last oder zu kurzem Kabel. Ist dein BMS korrekt konfiguriert?

  Oh wow, I thought my battery was dead! Now I get it, this is normal for LiFePO₄.
