Sealed lithium iron sulfate battery (LiFePO4) | Big Power Prismatic Cells (BPC) | absolutely maintenance-free

Forster PremiumMaximum capacity and lifetime.


With optimized high load BMS control and expandable capacity optimized lithium battery for use in camping, marine and as energy storage.
Our recommendation if you want an extra powerful and long life supply battery.

Features

  • Maximum service life

    Unlike lead-acid batteries, which sulfate at low charge, the LiFePO4 battery is resistant to deep discharge. Thanks to its particularly robust cell technology, it can withstand even more charging cycles to a significantly lower depth.
    Your advantage: You get an extremely durable battery.

  • 100% usable capacity and expandable

    Unlike lead-acid batteries, the entire energy of this extremely compact LiFePO4 can be used. In addition, an infinite number of batteries of the same type can be connected in parallel.
    Your advantage: There are no limits to the capacity.

  • Also available as under seat battery

    In this version, the battery is precisely tailored for the space under the driver or passenger seat of motor homes such as Fiat Ducato, Ford Transit and PSE. The mounting of the optionally available measuring shunt is prepared. An emergency stop switch on the housing interrupts the connection to the positive pole.
    Your advantage: Optimally prepared for under-seat installation.

Characteristics

  • Safe lithium technology (LiFePO4).
  • Maximum space utilization due to large prismatic cells (Big Power Prismatic Cells / BPC).
  • Under-seat variant optimally adapted to the space under the driver and passenger seat. (Fiat Ducato, Ford Transit and PSE)
  • 200 A high-load power BMS for continuous currents up to 200 A and peak currents up to 400 A.
  • 100% usable capacity. Complete discharge without damaging the battery. No sulfation. High performance during the entire discharge period.
  • Extremely long life expectancy at full capacity utilization. Up to 6,000 cycles at 80% depth of discharge (= 80% DOD).
  • Arbitrarily high capacity by parallel connection of any number of batteries of the same type.
  • Supports almost all boosters, shore chargers and solar charge controllers thanks to Multi Charge Mode (MCM).
  • Extended cold resistance for use down to -20°C.
  • High heat tolerance for safe supply even at ambient temperatures up to 60° C.
  • Optional: monitoring via 500 A Bluetooth mass shunt with Victron Smart Connect app. Measures, calculates and documents a wide range of battery parameters.
  • Very low self-discharge. Loses only 1 to 2% charge per month.
  • PROTECTION CLASS IP67 for use even in humid/wet conditions.
  • Fully charged extremely quickly. bsorbs extremely high charging currents in a very short time (charging time depends on capacity and charger).
  • Weight and space savings of up to 75% compared to a conventional battery of the same capacity.
  • Flexible installation position. Can be installed upright, lying down, upside down and in any other position.
  • Ready for installation and immediate use.
  • Absolutely maintenance-free.

Battery knowledge

Every battery ages
With each charge/discharge process (cycle), active material is inevitably lost and the battery's performance declines. Once it has fallen to the point where it can no longer fulfil its purpose - e.g. start the vehicle, supply the consumers or drive the …
What does absolutely maintenance-free mean?
Absolutely maintenance-free batteries are valve-regulated lead-acid batteries or VRLA batteries (VRLA = Valve Regulated Lead-Acid) that are sealed at the factory. Here, significantly less gas is produced than in wet batteries. The gas produced remains …
Identifying and filling the liquid level
Markings on the outside of the white or transparent housing of a wet battery indicate the minimum (MIN) and maximum (MAX) fill levels. During commissioning or initial filling, the battery must be filled with battery acid up to the upper mark (MAX). During …
Supply batteries with grid plates
Wet (flooded) deep-cycle lead-acid batteries with grid plates are particularly suitable for small and medium-sized solar applications and wind turbines thanks to their good capacity absorption and maximum capacity reserves. Grid plate technology is robust …
What is a solar battery?
Utility batteries, which can be used as temporary storage for photovoltaic (PV) or small wind systems, are highly cycle resistant, meaning they can withstand different charging cycles well. In the renewable energy sector, charging cannot be done with …
What types of supply batteries are there?
In order to withstand the stress of cyclic operation for a long time without an excessive drop in performance, the active material in supply batteries is particularly well protected. Depending on the technology used, this is done in different ways: In …
Cleanliness pays off
To ensure proper battery function, it makes sense to keep the battery surface clean and dry. Greasy or silicone-containing dirt on the lid can hinder the flow of current. Moisture on the battery can cause a short circuit in the worst case.
Determine excessive self-discharge
If the battery charge drops significantly, possibly overnight, this may be due to leakage current. Silent, unwanted loads can be detected with an ammeter. Oils or liquids deposited on the surface of the battery can also cause considerable self-discharge. …
What is wear and what can you do about it?
With a worn battery, the active material has degraded due to excessive load. Modern vehicles with many consumers constantly place higher demands on the battery. The capacity of the installed batteries is often not designed for this. Prevention The choice …
Round cell supply batteries
Similar to the tank cell, the surface area is increased by "winding" the grids, resulting in a larger amount of active mass. The box size is relatively compact, so you get the benefits of a utility battery in a small space, along with good starting …

What is a Supply Battery?

Supply batteries must provide power for as long as possible for consumers that are not connected to the regular power grid or the starter battery. Either in mobile applications, e.g. camping or in island installations such as mountain huts, or in safety applications when the normal power grid fails or to compensate for so-called mains wipers. Depending on the application, they are charged with a charger from the mains or via smaller photovoltaic or wind power systems.

So not only do they have to supply power for a long time and then take it up again well, but they also have to cope well with changing current levels and voltages.

Supply batteries are cyclic batteries, i.e. they are designed to continuously deliver current up to a maximum depth of discharge of 80% when supplying electrical consumers and then to be fully recharged again. In contrast, a starter battery delivers a short, strong current surge for starting the engine and is recharged by the alternator while driving.
