Engine charging causing hysteresis

Hello, I have a Victron Cyrix-CT charging my Battle Born Lithium batteries while the engine is running. I get a High Limit (hysteresis) warning when I'm at full charge and driving since it hits 14.8 volts. The BMS will prevent a charge if it exceeds 14. 7 volts. So I would assume that this is just noise that I don't need to worry about. If that is the case does anyone know how to stop getting alerts on it? Thanks for the feedback


Voltage: 14.81
Low limit (hysteresis): 11.8 (12.2)
High limit (hysteresis): 14.8 (14.7)
Wait time: 60 seconds

The CT is for wet batteries. For a wet starter battery and a lithium house battery you need the Li-Ct

My thoughts would be that you should reduce the alternators charge voltage under bulk to 14.4 (suspect a incorrect regulator setting or battery type) or there abouts as 14.8 is above the recomended charge level from what you are discribing.
