I have a 200Ah lithium battery bank connected to my starter battery/alternator via a Cyrix-Li Charge 230A controlled by the BMV 712-Smart.
It's currently configured to only connect when the starter battery is over 14.1V (indicating that the engine is on) and to cut off when the starter drops below 13.7 (when the engine turns off). I'd like to add another condition that my lithium battery bank must be below 95% to protect against overcharging. Not having luck with the state of charge. Anyone have guidance?
Desired Logic:
ENGINE ON, BANK < 95% = Closed Circuit (aka charging)
ENGINE ON, BANK > 95% = Open Circuit (aka not charging)
ENGINE OFF, BANK < 95% = Open (aka not charging)
ENGINE OFF, BANK > 95% = Open (aka not charging)
