The Cyrix-Li-CT 12/24V-1220A battery coupler from Victron Energy (MPN Cyr010120412) for 12V and 24V LIFEPO4 Batteries or lead-acid starter batteries. It can work with a maximum stream of 120a and is an ideal addition to the VE.Bus BMS as a battery switch for those loads that the VE.Bus BMS cannot switch independently.

Function of the Cyrix battery couplers in general

The Cyrix-Li-CT 12/24V-1220A is a high-performance microprocessor-controlled relay, which automatically switches batteries in parallel when a specified voltage value has reached (which shows that the batteries are loaded) and, which the batteries are released again Separate if the voltage drops below the conservation voltage value (which shows that one or both batteries are being discharged). Cyrix battery couplers are ideal for replacing separation diodes. Their main feature is that there is practically no voltage loss, so that the output voltage of the alternating current generators or the battery charger does not have to be increased.

Working method of the Cyrix-Li-CT 12/24V 120A

The functionality of the Cyrix-Li-CT 12/24V 120a corresponds to that of the Cyrix-CT.

The Cyrix-Li-CT connects a lead-acid starter battery and a LIFEPO4 battery:

  1. If the output "Charge Disconnect" of the VE. Bus BMS is high
  2. If he measures 13.4 V (or 26.8 V) or more on his power connections

The Cyrix-CT switches off immediately:

  1. When its control output reaches the "Free Floating" state (open circuit)
  2. When its control output shows a cell overvoltage or a cell over temperature
  3. If the battery voltage drops to less than 13.2 V

Start assist function: A short positive impulse closes the relay for 30 seconds (see illustration on page 2). A built-in TVS diode limits the tip of the voltage that can occur if the Cyrix suddenly switches off due to a cell overvoltage or over temperature.

Important technical features

  • Manufacturer number number: Cyr010120412
  • Permanent current and switch -off flow: 120a
  • For 12V and 24V battery voltage
  • Works with Lifepo4 or lead-acid starter batteries

Cyrix-Li-CT as a perfect addition to the Ve.Bus BMS

The Ve.Bus BMS is a central core of the protective precautions for Victron Lifepo4 Batteries. However, not all loads or chargers can be controlled directly via the Ve.Bus BMS. In order to switch off such loads or chargers, several Ve.Bus BMS controllable Cyrix switches are available.
