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 in 60 minutes. Accepts enormously high charging currents in the shortest possible time.
  • Weight and space savings of up to 60% 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

What does damage to the battery box indicate?
Damaged battery box If the housing is leaking, cracked or chafed, this indicates destruction by external influences. Tip: Look for a robust design in your next battery. Deformed battery case If the housing is deformed by heat, this indicates a defective …
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 …
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 …
Checking the battery step by step
There are many reasons for weakening or failing batteries. An important step in tracking them down is to measure the voltage with a battery tester. Here's how: 1. preparation Disconnect the battery from the vehicle, if possible remove it. Tips on how …
What is sulfation and what can you do about it?
Sulphation or sulphation is an undesirable ageing process in batteries where too much lead sulphate forms on the lead plates, which cannot be removed even with prolonged charging. The battery's capacity drops significantly, or it fails altogether. Sulfation …
Checking the liquid level against sulphation
In a battery or accumulator, the chemical reaction between the active material of the grids and the acid generates current (electrons emitted) to supply the loads or stores current (electrons) provided by the charger or alternator. If the acid only partially …
The difference between low maintenance, maintenance free and absolutely maintenance free.
Low-maintenance, flooded lead-acid batteries lose fluid during normal use. They must be maintained, i.e. the fluid level should be checked regularly and the fluid loss compensated with distilled water if necessary. These batteries usually have vent caps …
Supply batteries with armoured plates
Wet deep-cycle batteries in armoured plate or tubular plate technology are designed for the most severe loads. Due to their structure, the tubular plates used provide a larger surface area compared to grid plates and thus more active mass for the chemical …
Knowledge
Depending on the type, this battery is low-maintenance or maintenance-free. Low maintenance version - TV types Low-maintenance batteries can be recognised by the removable sealing plugs on the top, the vent hose and the white or transparent housing. In …
What waterproof brings
Ideally, batteries should be kept dry. Even slight moisture can promote leakage currents. If you've noticed condensation on your battery frequently in the past, such as with temperature fluctuations, or water can get to your battery, it's worth considering …

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.
