Product description

Experience the future of energy supply with the Berger LiFePO4 under-seat battery

With a capacity of 300 Ah and a discharge current of 250 A, this battery is ideal for demanding applications in your motorhome and caravan. Its low weight and fast charging times ensure maximum efficiency. Thanks to Bluetooth, you can conveniently monitor the battery via your smartphone. This battery offers you the perfect combination of capacity, load tolerance and freedom from maintenance.

PRO version with heating - maximum performance even in the cold!

When it comes to the performance and longevity of lithium batteries, optimum temperature conditions are crucial. An integrated heater in your battery offers numerous advantages:

  • Improved performance - even in the cold: With a heater, the temperature of the battery is kept at an optimal level, so you can count on reliable performance even in freezing conditions.
  • Protection against damage caused by low temperatures: Low temperatures can not only reduce performance, but also lead to permanent damage to the battery
  • Extended service life: Deep discharges at extreme temperatures are prevented, which increases the overall service life of the battery.
  • The heating function is automatically activated when the temperature of the battery is ≤0 °C during the charging process

    Specifications and special features:

    • Significantly lower energy losses than a comparable AGM or gel battery
    • The compact Berger under-seat battery is ideal for under the passenger seat in the motorhome
    • Short charging times for maximum efficiency
    • Stable voltage: appliances such as toasters and air conditioners can be operated without any problems
    • Bluetooth monitoring: Simply monitor the battery with your smartphone (iOS/Android)
    • High cycle stability: Durable and reliable
    • Weight advantage: Despite over 50% less weight (only 30.5 kg), same design compared to lead batteries
    • Versatile charging options: Charging with shore power and solar panel
    • The integrated battery management system (BMS) monitors and controls the battery. This optimizes the performance, service life and safety of the battery

    Customer questions

    Is the battery also suitable as a starter battery?

    The Berger LiFePO4 battery is primarily designed for deep-cycle applications such as solar storage, motorhomes or on-board power supply. It is not intended for use as a starter battery, as starter batteries have different requirements in terms of short-term current and cold behavior. For optimum function and a long service life, we recommend using it as a supply or body battery.

    Is the battery compatible with conventional chargers for AGM or gel batteries?

    The Berger LiFePO4 battery is optimized for operation with LiFePO4-compatible chargers. Many modern chargers can be set to a lithium or LiFePO4 mode and can therefore be used without any problems. Conventional AGM or gel chargers without a suitable lithium characteristic curve may result in incomplete charging or reduced performance and service life. For the best possible performance, maximum safety and full capacity utilization, we therefore recommend using a charger with explicit LiFePO4 approval. Many high-quality chargers for AGM or gel batteries have a lithium mode or are approved for LiFePO4 batteries according to the manufacturer. Please check the charger manufacturer's specifications.

    When is the battery heater activated?

    The heating function is activated automatically as soon as the battery temperature is ≤ 0 °C during the charging process. At this point, the BMS (battery management system) interrupts the charging process and gives priority to the heating. As soon as the temperature reaches +5 °C, the charging process continues automatically. If the temperature rises above 10 °C, the heating function is deactivated.

    Does my charger need to be converted?

    In many cases, no conversion is necessary. Many modern AGM or gel chargers have a lithium or LiFePO4 mode or can be set accordingly. If your charger does not offer a setting, we recommend using a LiFePO4-enabled charger in order to utilize the full capacity and service life of the battery.

    Note

    Please note: since our deliveries may contain batteries (single-use and rechargeable),
    according to the German Law on Batteries (BattG) we must advise you of the following:

    single-use and rechargeable batteries must not be disposed of along with domestic waste, but rather you are legally required to return used batteries. Used batteries may contain damaging substances which, if not stored or disposed of appropriately, may damage the environment or your health. Batteries may, however, also contain important raw materials, such as, for example, iron, zion, magnesium or nickel, which can be recycled. Once used, you may either send the batteries back to us, or return them in
    your vicinity (e.g. at the shop, communal recycling points or at our expedition warehouse) - free of charge. When returning used batteries to points of sale, the quantity you are allowed to return is limited to the quantity typical for a single end user, and to those batteries which the seller offers or used to offer in their product range.

"Alles top bis auf die App da kann jeder der sie hat auf deine Batterie zugreifen. Schade das das nicht behoben wird. Aber die Batterie ist sehr gut. "

    "Does this battery also fit under the driver's seat of a 2012 Multivan? Or which battery would you recommend? The battery needs to go under the driver's seat. Could you perhaps answer that question for me?" "Past deze accu ook onder de bestuurdersstoel van een multivan uit 2012? Of welke accu raden jullie dan aan? De accu moet onder de bestuurders stoel komen , kunnen jullie mij daar misschien antwoordt opgeven? "

    "The battery is really good. Enough power for several days without recharging. I was disappointed by the delivery time, which was stated as two days. In fact, it took 14 days. I think it would be better to give a realistic delivery time. For those who are installing it themselves, the foam panels in the packaging are ideal for installing the battery under the driver's seat." "Die Batterie ist richtig gut. Ausreichend Power für mehrere Tage ohne nachladen. Schade fand ich die Angaben zur Lieferzeit die mit zwei Tagen angegeben wurde. Tatsächlich waren es 14 Tage. Ich fände es besser eine realistische Lieferzeit anzugeben. Für alle die den Einbau selbst vornehmen, die Schaumstoff Platten in der Verpackung eignen sich hervorragend für den Einbau der Batterie unterm Fahrersitz. "
