Hi i have large 200 amp 24v alternators that charge the engine agm batteries and then the cyrix between engine and 1000 ah smart batteries.
If the soc of Li batteries is high enough 60-70% then the cyrix closes contact and charging is perfect.
if the soc of Li batteries is 20-60% then the cyrix will not close and hold contacts [tends to switch on and off]
If i close the emergency parallel switch between engine and smart batteries then charging is good at any soc.
I think the setpoints for the cyrix are incorrect for proper combining at all soc.
