    Power 26-104 High-performance Lithium Battery

    Integrated information system:
    Identifies the battery and communicates with the Cruise on-board computer.
    Waterproof housing and waterproof plug connections (IP67)
    Plug & play with the Cruise on-board computer:
    plug the cable in, “electronic handshake”, finished.
    Water sensor protection:
    recognises when the battery is submerged and automatically switches the voltage off at the poles. Prevents the potential formation of electrolytic gas in the event that water gets into the boat.
    Waterproof venting
    balances differences in temperature and pressure without limiting waterproof qualities.
    Double protection – isolatable poles:
    for safe transport and installation And preventing unintentional discharging when stored for long periods
    Safety cells with multiple protection:
    the individual battery cells consist of welded steel cylinders each of which is equipped with several hardware safety mechanisms.
    High-performance lithium battery cells:
    top quality, exclusively from fully automated Japanese production.
    Mature intelligent battery management system (BMS):
    the BMS provides additional protective and balancing functions for long battery life. All safety functions have redundant backup thanks to one-defect safety.

  • Tips

    Power 26-104 FAQ

    • What type of appliance can I use the Power 26-104 with?

      In principle any 24 V appliance that you otherwise operate on board, or 12 V, 110 V and 230 V appliances with a voltage converter.

    • What is the life expectancy of the Power 26-104?

      The life expectancy of a lithium battery depends on calendar age and cycle lifetime. In recreational use the cycle lifetime hardly plays a role since a relevant number of cycles (over 500) is usually never even almost achieved.
      In contrast, calendar ageing plays a significant role. Lithium batteries begin to age from the moment they are manufactured. This ageing process is accelerated the more/more frequently the battery is exposed to high temperature. Lithium batteries may also be used at high temperatures, but they should be stored in a cool place as often as possible. The annual capacity loss over time is approx. 4% (at 25 °C ambient temperature).

    • I rarely use my battery and store it for long periods. Will this damage a Power 26-104?

      The new Power 26-104 models (2015) have an automatic deactivation mode. The battery's electronics will be switched off 48 hours after the last use and the battery will be put into deep-sleep mode. The battery can remain in this mode for up to a year provided it is charged to at least 30% of capacity. Even so, a check should be made on the battery's charge status every two months when stored for long periods.
      The battery should be quickly recharged after every deep discharge. Discharging a battery fully and then storing it for a long time (without charging it) should be avoided at all costs since that damages any type of battery.

    • How long does the Power 26-104 take to fully charge?

      Charging takes approx. 11 hours using the charger supplied (from complete discharge, i.e. 100% depth of discharge).

    • Why does the Power 26-104 have a discharge limit?

      One of the advantages of lithium batteries is that they can supply very high currents. The disadvantage of this is that lithium batteries can cause considerable damage in the event of a short circuit – unless such high short-circuit currents can be avoided. This is an important safety function of the Power 26-104 and is part of the BMS. If higher discharge limits are required, several batteries can be connected in parallel, which multiplies the discharge limit.

    • Can I connect several Power batteries together to form a battery bank?

      Yes, that is possible. The integrated battery electronics recognise and classify the batteries.

    • What is the warranty on the Power 26-104?

      As with all our products, we give a 2-year warranty from the date of purchase for non-commercial use.

    • Is the Power 26-104 suitable for the installation of battery banks?

      The Power 26-104 is ideal for the installation of battery banks. You can choose between a serial or parallel connection. Please make sure to read the operating instruction for more details.

      Figure – parallel connection parallel connection Figure – parallel connection parallel connection

      Two Power 26-104s can be wired in series by connecting the positive pole of one battery with the negative pole of the other . The consumer appliance is then connected to the positive pole of the first battery and the negative pole of the second. The figure shows how 2 batteries have been wired together in series (2S1P connection).

      Figure – serial connection serial connection Figure – serial connection serial connection

      Several pairs of serially wired batteries can be connected with each other in parallel (2S2P connection) in order to increase the capacity of the battery supply. Up to 8 pairs of serially wired batteries can be connected in parallel in this way.
