Victron Cyrix-Li-Load 12/24V 230A
Battery Isolators & Combiners
The Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.
The LiFePO4 Battery: Preventing Cell Under Voltage, Overvoltage & Over Temperature
The first line of protection is cell balancing. All Victron LiFePO4 batteries have integrated cell balancing.
The second line of protection consists of:
• Shut down of the load in case of an imminent cell under voltage and,
• Shut down or reduction of the charging current in case of imminent cell overvoltage, high temperature (>50°C) or low temperature (<0°C)
The Cyrix-Li-Load will disengage when its control input becomes free floating. If the battery voltage recovers after disconnection (which will happen when no other loads are connected to the battery), the output of the BMS will become high and the Cyrix will re-engage after 30 seconds. After 3 attempts to re-engage, the Cyrix will remain disengaged until battery voltage has increased to more than 13V (resp. 26V or 52V) during at least 30 seconds (which is a sign the battery is being recharged). Alternatively, a BatteryProtect can be used (advantage: very low power consumption).
