Victron Cyrix-Li-load 12/24V-120A battery combiner - CYR010120450

Prevents undervoltage, overvoltage and overtemperature of Victron LiFePo4 battery cells.

The first line of protection is cell balancing. All Victron LiFePO4 batteries integrate cell balancing.
The second line of protection consists of:
- disconnecting loads in the event of imminent undervoltage in the switchgear, and
- disconnect or reduce the load current in case of imminent overvoltage, high temperature (>50°C) or low temperature (<0°C) in the cells.
The VE.Bus BMS is the heart of the second line of protection.
However, not all loads or chargers can be controlled directly with the VE.Bus BMS.
Several Cyrix switches are available to turn off these loads or chargers and are controlled by the VE.Bus BMS.

The Cyrix-Li-load will disconnect when its control input becomes floating.
If the battery voltage recovers after disconnection (which will occur when no other loads are connected to the battery), the BMS output will go high and the Cyrix will reactivate after 30 seconds. The Cyrix, after attempting to reactivate 3 times, will remain deactivated until the voltage rises above 13 V (26 V or 52 V, resp.) for at least 30 seconds (which is a sign that the battery is being recharged).
Alternatively, a Protect battery can be used (advantage: very low power consumption).
