Battery Storage Accessories

    Backup Switchgear

    Devices to enable whole house backup alongside various battery or hybrid inverters.

    Battery Accessories

    A range of battery accessories are available including terminals, hydrometers, deionised water etc.

    Battery Combiners

    These connect multiple separate battery banks in parallel without allowing unwanted charging or discharging between banks.
    • Victron Cyrix Battery Combiners

      Victron Cyrix Battery Combiners

      4 models available
      From £43.66

      Used for instance to connect engine starter and service batteries to allow charge from the same alternator, whilst prioritising charge to the starter battery.

    • Victron Diode Battery Combiner

      Victron Diode Battery Combiner


      These are used to guarantee continuous DC power to mission critical equipment, such as an electronic engine control system. With a diode battery combiner two or more DC power sources can be used in parallel to supply the mission critical load. Failure of one source will not interrupt power to the critical load.

    Battery Relays

    These relays are used to switch various loads and charging sources when connected directly to a battery.
    • Victron Battery Protect

      Victron Battery Protect

      8 models available
      From £30.47

      The Victron Battery Protect disconnects the battery from loads before the battery is completely discharged, this prevents damage to the battery and will leave some charge in the battery e.g. to start an engine.

    • Victron Cyrix Intelligent Charge Relays

      Victron Cyrix Intelligent Charge Relays

      3 models available
      From £45.00

      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).

    • Victron Cyrix Intelligent Load Relays

      Victron Cyrix Intelligent Load Relays

      2 models available
      From £57.91

      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 reengage after 30 seconds. After 3 attempts to reengage, the Cyrix will remain disengaged until battery voltage has increased to more than 13 V (resp. 26 V or 52 V) during at least 30 seconds (which is a sign that the battery is being recharged).

    DC-DC Converters

    DC to DC converters convert the input voltage to a higher or lower output voltage enabling a wider range of appliances to be used.

    A common example is to power 12V appliances from a 24V battery; 12V appliances are more readily available than 24V appliances.
