    High quality lead battery replacement with a longer service life!

    With the lithium-iron-phosphate technology, previous lead, gel and AGM batteries can be replaced quickly and easily. The specified capacity can be almost fully used and the weight is up to 75% less than a comparable lead-acid battery.

    Another big advantage is the low self-discharge, which significantly simplifies and extends the storage or service life. Even if the available capacity is almost fully used, the lithium technology with 3000 cycles enables a seven times longer service life than previous batteries.

    The standard battery series is offered for 12V, 24V and 36V installations. Both parallel connection to increase capacity and series connection to increase voltage up to max. 48V are possible.

    Multi-Charge-Mode (MCM) / compatible with common chargers

    Up to now, lithium batteries could only be charged with lithium chargers. When replacing the regular batteries with lithium, the chargers also had to be changed. With the FORSTER Multi-Charge-Mode Software (MCM) you can continue to use 99% of the devices such as boosters, shore chargers or solar controllers. This saves you additional costs and includes the manufacturer's guarantee for new vehicles.

    Bluetooth monitoring / state of charge display (SOC)

    Batteries with integrated Bluetooth monitoring allow you to display the most important battery data on your smartphone or tablet. The free APP "FORSTER Smart Connect" shows you the following data in real time:

    • Charge status of the battery
    • Remaining runtime with current consumption
    • battery voltage
    • Battery nominal capacity
    • charging and discharging current
    • Battery temperature
    • Charge and discharge cycles
    • Warning messages of limit values

    Safety / Safety First

    The latest lithium iron phosphate technology offers a high degree of intrinsic safety, so that there is no risk of explosion even under the most extreme conditions. A LiFePO4 battery consists of individual cells connected in series and a battery management system (BMS). The BMS monitors and protects the battery cells from damage during charging and discharging.The standard FORSTER BMS assumes the following safety functions:

    • overload protection
    • deep discharge protection
    • overvoltage protection
    • Active cell balancing
    • load control
    • Cell Frost Control (CFC), charging current reduction below 0°C
    • Multi-Charge-Mode (MCM)Compatible with common chargers
    • Temperature cell monitoring
    • Temperature BMS monitoring

    Product quality

    The independent German development of the battery management system is the basis for our quality standards. In addition, FORSTER INDIVIDUAL BATTERIES not only tests and documents production, but also all batteries on the shipping day again before delivery.

    5 year guarantee

    As the manufacturer, FORSTER INDIVIDUAL BATTERIES 5-year guarantee on the battery advertised with the guarantee promise.
