Portable Battery Pack

  • What is a portable battery or portable power station?

    A portable battery, also called a portable power station or battery pack, is a mobile energy storage unit that stores electrical energy in lithium batteries. It provides 230 V power without noise, emissions or fuel consumption, making it a quiet alternative to a generator on the construction site.

  • What is the difference between a battery pack and a generator?

    A battery pack operates entirely electrically, produces no emissions and requires no maintenance. A generator runs on gasoline or diesel, is noisy and requires regular maintenance. So in urban or indoor areas, a battery pack is often the only permissible option.

  • Why choose LiFePO4 technology on site?

    LiFePO4 batteries are safe, stable and have a long service life of up to more than 3,000 charge cycles. They pose no fire hazard like older lithium types and remain reliable even during intensive use on construction sites.

  • Is a portable battery suitable for outdoor use?

    Yes. The Renopower BW series has an IP54 protection rating, which means they are dustproof and waterproof. They are designed for professional use on construction sites. The BWC series even has an IP65 protection rating.

  • Can I combine my portable battery with a generator or grid power?

    Yes, LiFePO4 battery packs can operate hybrid. They can be charged from the grid or act as a buffer alongside a generator to reduce fuel consumption and noise.

  • Where can I buy or test a professional portable battery?

    Fimatec offers the Renopower BW2500, BW3600 and BW5000 from stock, with tailored advice and in-house service.

  • What is the difference between primary and secondary batteries?

    Primary batteries (such as AA alkaline) are not rechargeable.
    Secondary batteries, such as the LiFePO4 cells in Renopower battery packs, can be recharged thousands of times.
    This makes them ideal for professional use, where reuse, durability and low operating costs are essential.

  • How fast can I charge a LiFePO4 battery?

    The charging rate depends on the charging current (in amps) and the internal electronics.
    The Renopower BW series supports fast charging via mains or solar power, with efficient charge management that prevents overheating.
    Our batteries typically fully charge within a few hours.

  • Do LiFePO4 batteries need built-in protection?

    Yes. Every Renopower battery has an integrated Battery Management System (BMS) that continuously monitors temperature, voltage and charge status.
    This prevents overcharging, deep discharging or overheating - crucial for professional and safe use.

  • Are portable batteries recyclable?

    Yes. LiFePO4 batteries contain no cobalt or heavy metals and are therefore more environmentally friendly than other lithium variants.
    At the end of their life cycle, the cells can be recycled through authorized collectors.
    Fimatec only works with producers who comply with European recycling standards.

  • What does self-discharge mean in a battery?

    Self-discharge is the natural process by which a battery slowly loses energy even when not in use. Thanks to LiFePOâ‚„ cells, Fimatec batteries have extremely low self-discharge, making them ideal for seasonal use or long-term storage.
