Cyrix-Li-ct Battery combiner 120A for Lithium Batteries

low voltage loss, processor controlled

designed for Marine, KFZ, Camping, Caravan

The functionality of the Cyrix-Li-ct is analogous to the Cyrix-ct, the switching thresholds are adjusted to lithium batteries..

The Cyrix-Li-ct will parallel connect a lead acid starter battery and a LiFePO4 battery:
- if the Charge Disconnect output of the VE.Bus BMS is high,
- if it senses 13,4 V (resp. 26,8 V) or more on one of its power terminals.

The Cyrix will disengage immediately:
- when its control output becomes free floating, signalling cell over voltage or cell over temperature,
- when battery voltage drops below 13,2 V

Start assist function:
a short positive pulse will close the relay during 30 seconds (only if VE.Bus BMS is available)

A built-in transient voltage suppressor will limit the voltage spike that may occur when the Cyrix suddenly disengages due to cell overvoltage or over temperature.


Connect voltage delay Disconnect voltage delay
<13,4V no connection >13,3V connected
13,4V - 13,7V 120 seconds 13,3 - 13,2V 10 seconds
13,7V - 13,9V 30 seconds <13,2V immediate
>13,9V 4 Sekunden    
(Approximate delay times for connection and disconnection)
(multiply voltage value by a factor of 2 in a 24 V system)
