I have a 2022 RV with a smart alternator and smart bms cl 12/100 with a Victron 330 AH lithium battery. My issue is the battery is only getting charge when I lift off the throttle! most of the time the vehicle battery is at 12.7 volts until I lift off when it climbs to 14 volts and the bms starts charging until I press the accelerator again and it goes back to 12.7 volts. Help please?
