Everything has been working great, had an enjoyable golden hour flight tonight, OAT 60F, perfect conditions. I turned on IBBS and saw 12.7V wondering what the state of my IBBS battery is. That seems a bit low if it is in fact a LiFePO4 battery. Maybe it's because I haven't flown enough to get it charged? So I'm curious from others, when you turn on IBBS, realizing it's under load, what voltage are you seeing?
During flight I saw a max of 13.3 which seems odd as my other two LiFePO4 (EarthX) batteries show 14.1V at full charge. Maybe it's not charged yet? Maybe the battery has a bad cell? What are you seeing for a fully charged TCW IBBS battery?
