Cyrix-ct 12/24V 120A Battery Combiner will parallel connect a lead acid starter battery and a LiFePO4 battery if the Charge Disconnect output of the VE.Bus BMS is high, and if it senses 13,4V (resp. 26,8V) or more on one of its power terminals.
Cyrix-ct 12/24V-120A Battery Combiner will disengage immediately when its control output becomes free floating, signalling cell over voltage or cell over temperature and/or when battery voltage drops below 13,2V.
