Lithium - An element that provides power

Lithium is characterized by extreme lightness, as it is the lightest metal in nature and also the solid with the lowest density and the greatest electrochemical potential. These properties provide excellent energy performance despite its light weight.

No wonder lithium is the ultimate in battery development. Depending on the chemistry composition used, a typical lithium-ion battery produces 2.4 to 3.7 volts per element.



A short excursion into science - the chemistry is simply right here!

After intensive research, we have chosen Li-Fe-PO4 chemistry for our lithium batteries, which is currently the safest and most stable composition for batteries on the market. This composition allows a much longer lifespan with more than 4000 charging cycles.

Another advantage using this composition is that it can also be provided for large capacity formats (100, 200, 300 Ah), which are particularly relevant for industrial applications. Therefore, a parallel connection of many individual small cells is no longer necessary and the stability and safety of the batteries is not put at risk.



Intelligent charge control ensures a long life cycle

The cells of a lithium battery have different capacities, resistances and self-discharges, which is why there are slight differences in the charging processes, especially when charging several batteries. In practice, this means that one cell is fully charged, while another cell is only 95% charged.

At first glance, the difference may hardly be noticeable. However, with each additional charge cycle, this difference adds up and eventually leads to a high discrepancy, which in the worst case can result in severe damage and malfunctions, both to the battery and to the vehicle or machine.

To avoid this loss of efficiency, the internal electronics of the Flash Battery lithium battery intelligently balance the charge levels in the cells during a charge or discharge process.

Conventional balancing systems lower the charge level to match the lowest cell by applying resistance to the cells with the largest charge. In principle, this method is quite simple and inexpensive, but it takes a relatively long time: four to eight hours are needed on average for balancing alone, in addition to the initial charging process. Moreover, these processes for balancing must not be interrupted, otherwise the available energy will be reduced and vehicles as well as machines will lose operating time.

How did we solve this problem? By using a special active and passive balancing process already during the charging cycles, we ensure that the charges are balanced 20 times faster, thus guaranteeing maximum operating time at all times.

Combined charge balancing



Short charging times

from less than 30 minutes


Active support

A maintenance-free technology saves time and costs

By using special control electronics inside our lithium batteries, regular maintenance work is no longer necessary, which subsequently leads to enormous savings.

The core of the whole concept lies in the interaction between the internal architecture of the battery, the combined charge balancing and the extensive analysis and remote monitoring capabilities. Repairs can thus be carried out directly at the user's site by non-specialized personnel, eliminating complicated transport costs and long downtimes.



Important parameters always in view - The Flash Data Center for efficient remote monitoring

The remote monitoring system (Flash Data Center) is the mind behind the lithium batteries. On a daily basis it reports any faults that may arise and determines the status of each individual battery at all times. This is how you protect your batteries from unwanted misuse or technical anomalies.

The software is designed to also detect and eliminate false signals. This prevents errors in general, before you as a user even notice it.

The Flash Data Center offers:

  • a monitoring of all parameters for each individual battery
  • a comprehensive analysis of all usage data for the optimization of your machines and vehicles
  • notification of malfunctions
  • continuous, automated fault prevention
  • organization options for extraordinary repairs
  • enormous savings in maintenance costs
  • increased productivity of machines and vehicles

Safety comes above all

Safety is one of the multiple strengths of our lithium batteries. We use only the safest chemistry available on the market. Even in the event of a short circuit, it remains intact. How does that work?

FlashBattery lithium batteries are equipped with safety valves which, in the event of an anomaly, releases only internal electrolytes to avoid exceeding the 80°C temperature.



Adaptability says it all

Our lithium batteries are equipped with their own heating and cooling systems to ensure safe and powerful operation at temperatures ranging from -30°C to +45°C. This way, the batteries remain powerful and adapt perfectly to different application areas - for example, cooling systems in the industrial sector.


Branches that benefit from the use of lithium batteries:


Agricultural machines

The European agricultural sector is showing a strong trend towards electrification, especially in areas such as viticulture, zootechnics and the conservation of green spaces. In viticulture, it is now possible to perform all land preparation work from brush cleaning to surfacing with all-electric machines. All-electric harvesters offer the same performance as heat machines, but also all the benefits of electricity: no maintenance and associated costs, CO2 emissions and lower noise levels. In zootechnics, automotive feed mixers (machines for mixing feed for animals, present in the most avant-garde farms and attentive to animal welfare) represent a new electric solution. Most of these applications involve high-voltage batteries, these require a great deal of mechanical adaptation. Flash Battery makes battery customization in terms of size and power its true strength. To date, the company produces more than 550 different models. In many cities, green space conservation is shifting to hybrid or all-electric systems. This trend is particularly evident in wood chippers, which benefit from the advantages of lithium in terms of emissions and noise suppression.


AGV and LGV vehicles

Automatically guided (AGV) and laser guided (LGV) vehicles

FTFs and LGVs are advanced technological systems that move autonomously, reducing lead times, costs and errors within the automated system of a logistics warehouse or production facility. Flash Battery lithium batteries in FTFs and LGVs improve system efficiency even with intensive use around the clock. All maintenance costs are eliminated and the remote battery condition monitoring system automatically performs self-diagnosis and preventive maintenance.


Special vehicles

The special equipment used in construction, maintenance of the railroad network or even tunnels, are industrial machines that require high power. Energy consumption should not be forgotten in the electrification of these applications. These sectors are extremely energy-intensive and therefore it is essential to give the machine enough autonomy and power if it is to be electrified. With lithium batteries from Flash Battery, all this is possible thanks to the increased energy density, which provides even more energy and power in a smaller volume and maintains the high level of safety that we guarantee worldwide. The 4G, with which this particular equipment is supplied, allows for preventive remote control. Data on battery operation and machine use are evaluated daily and automatically. The remote control plays a crucial role already during the design and pre-production phases: it allows the remote control of the actual consumption of the machine during the test phases and the first use in the field. The remote control also allows us to determine the actual charging and discharging times, the days of use, the average consumption and the temperatures reached, thereby optimizing the performance of the battery and the machine.
