Device type	BMS-controlled battery combiner for a lead acid starter battery and a LiFePO4 battery (VE.Bus BMS controllable Cyrix)Documented claim Conditions The datasheet prints that several VE.Bus BMS controllable Cyrix switches are available to shut down loads or chargers the BMS cannot control directly; the Cyrix-Li-ct parallel connects a lead acid starter battery and a LiFePO4 battery when the VE.Bus BMS charge disconnect output is high and it senses 13,4V (resp. 26,8V) or more, and disengages below 13,2 V; its functionality is analogous to the Cyrix-ct. The control input row is printed once: "The Cyrix engages when the control input is high (appr. Battery voltage) The Cyrix disengages when the control input is left free floating or pulled low".
