The LiFePO4 battery: preventing cell under voltage, over voltage and 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 imminent cell under voltage, and
– shut down or reduction of the charging current in case of imminent cell over voltage, high temperature (>50°C) or low temperature (<0°C).
The VE.Bus BMS is the core of the second protection line.
However, not all loads or chargers can be controlled directly by the VE.Bus BMS.
In order to shut down such loads or chargers several VE.Bus BMS controllable Cyrix switches are available.
Cyrix-Li-load
The Cyrix-Li-load will disengage when its control input becomes free floating.
If the battery voltage recovers after disconnecting (which will happen when no other loads are connected to the battery), the output of the BMS will become high and the Cyrix will reengage after 30 seconds. After 3 attempts to reengage, 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 that the battery is being recharged).
Alternatively, a BatteryProtect can be used (advantage: very low power consumption).
Cyrix-Li-Charge
The Cyrix-Li-Charge will connect a battery charger with 3 seconds delay:
– if the Charge Disconnect output of the VE.Bus BMS is high, and
– if it senses 13,7V (resp. 27,4V or 54,8V) or more on its battery charger connection terminal, and
– if it senses 2V or more on its battery terminal (the Cyrix will remain open, if not connect to the battery).
The Cyrix-Li-Charge will disengage immediately whenever its control input becomes free floating, signalling cell over voltage or cell over temperature.
In general a cell over voltage alarm will reset shortly after charging has been stopped. The Cyrix will then reconnect the charger after a delay of 3 seconds. After two attempts to reengage with 3 seconds delay, the delay increases to 10 minutes.
Whenever battery voltage is less than 13,5V (resp. 27V or 54V), the Cyrix will disengage with a delay of 1 hour.
Note 1: In case of zero discharge current, or a small discharge current, the Cyrix will not disengage shortly after the charger has been switched off and/or disconnected, because battery voltage will remain higher than 13,5V.
Note 2: If, after the Cyrix has disengaged, the output of the battery charger immediately increases to 13,7V or
more, the Cyrix will re-engage, with 3 seconds delay.
Cyrix-Li-ct
The functionality of the Cyrix-Li-ct is analogous to the Cyrix-ct.
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, and
– if it senses 13,4V (resp. 26,8V) 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,
and/or
– when battery voltage drops below 13,2V.
Start assist function: a short positive pulse will close the relay during 30 seconds (see figure on page 2).
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.

The Phoenix Charger Control panel provides remote control and monitoring of the charge process with LED indication of the charger status.
In addition, the remote panel also offers output current adjustment that can be used to limit the output current and thus the power drawn from the AC supply. This is particularly useful when operating the charger from limited shore power or small gensets.
The panel can also be used to change the battery charging parameters. The brightness of the LEDs is automatically reduced during night time. Connection to the charger is with a standard UTP cable.

Victron Energy MK2 interface module to connect PC to Phoenix. For use with v18 software and Phoenix chargers only.
- Brand: Victron Energy
Protects the battery against excessive discharge and can be used as a system on/off switch
The Smart BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.
The on/off input can be used as a system on/off switch.
12/24V auto ranging
The Smart BatteryProtect automatically detects system voltage one time only.
Bluetooth: programming made easy
When using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set.
Alternatively, one of nine predefined engage/disengage levels can be set with the programming pin (see manual).
If required, Bluetooth can be disabled.
A special setting for Li-ion batteries
In this mode the BatteryProtect can be controlled by the VE.Bus BMS.
Note: the BatteryProtect can also be used as a charge interrupter in between a battery charger and a Li-ion battery. See connection diagram in the manual.
Ultra-low current consumption
This is important in case of Li-ion batteries, especially after low voltage shutdown.
Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.
Over voltage protection
To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16.3V respectively 32.6V.
Ignition proof
No relays but MOSFET switches, and therefore no sparks.
Delayed alarm output
The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds.
Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.
Delayed load disconnect and delayed reconnect
The load will be disconnected 90 seconds after the battery voltage drops below the preset level. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected.
The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.

Diode battery isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together. Discharging the accessory battery for example will not result in also discharging the starter battery.
The Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes: at low current the voltage drop is approximately 0,3 V and at the rated output approximately 0,45 V.
All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator. This compensates for the voltage drop over the diodes in the isolator.
Simply inserting the isolator in the cabling between the alternator and the batteries will slightly reduce charge voltage. The result can be that batteries are not charged to the full 100% and age prematurely.
Alternator energize input
Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to a battery. Inserting a Diode or FET splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start.
The new ‘AC’ diode isolators feature a special current limited energize input that will power the B+ when the engine run/stop switch is closed.

The VE.Bus Smart dongle is two products in one:
First of all it is the bluetooth accessory for our range of inverter/chargers: Multis, MultiPlusses, MultiPlus-II, MultiGrid, MultiGrid-II, Quattros, and our series of Phoenix Inverters with a VE.Bus port. When installed, use the VictronConnect app to monitor operation and also operate the system: change the input current limit as well as switch between Off, On and Charger-only modes.
Secondly it can work as a Voltage- and Temperature-sense device for the inverter/charger. This works with all models.
For monitoring, the device is a great alternative in caravans, smaller yachts and motor homes for which the Color Control GX or Venus GX are a step too far.
