Development of Special solutions

With over 20 years of know-how, we are the expert for mobile energy solutions in Austria!

Battery pack assembly

Specially adapted battery packs are of great advantage, especially in industry. We go through an extensive quality assurance process when assembling our battery packs in order to achieve a higher standard of safety.

Selection of the chemical material and selection of the cells

To guarantee a product that meets modern standards, the selection of the chemical system and the subsequent selection of the respective cells is crucial.

We offer a diverse selection of systems (e.g. Li-Ion, LiFePO4, LiPo, NiMH, etc.).

Afterwards, the cells of the system are selected fully automatically according to internal resistance and voltage level, grouped according to their respective level and processed into a battery pack.
In this way, we ensure a homogeneous unit to guarantee the stability and service life of the batteries.

Dimensioning of the battery pack and arrangement of the cells

The cells are then sized in special containers, the so-called cell racks, and thus prepared accordingly for welding.

In the next step, the suitable welding connectors are selected and cut to a suitable format.
The welding is then done either automatically or manually.
Our semi-automatic spot welding machine (shown) welds battery packs from both sides simultaneously in the highest quality. This means that even series production can be completed quickly.
We also offer all our welding machines for sale, please feel free to contact us.

Unsere Akkus sind mit einer eigens entwi­ckelten und verbauten Schut­z­elek­tronik ausge­stattet, die ihn u.a. vor

  • Überla­dung,
  • Tiefen­ent­la­dung,
  • Kurz­schluss
  • und extremen Tempe­ra­tur­be­din­gungen schützt
  • sowie die Einzel­zellen über­wacht.

Nach der sorg­fäl­tigen Auswahl der geeig­neten Schut­z­elek­tronik wird diese am Akku­pack ange­bracht.

Now both the cross-section of the cable for the current strength of the battery and the respective material of which the cable is to be made are determined (e.g. PVC, rubber, silicone, etc.).
Then the battery pack is covered with a so-called GRP insulation.
This material is reinforced with glass fibre and serves as mechanical protection to insulate the battery.

Confection and shrinkage

The connectors of the battery pack are assembled according to the requirement.
After that, the shrinking of the battery pack can be started.

Firmware adaptation and quality assurance

The firmware of the battery pack can now be individually adapted to the customer’s wishes.

At the end of the process, numerous load tests are carried out and a quality assurance inspection takes place to ensure that the battery pack functions perfectly.

Tool battery packs

By exchanging cells, batteries that were thought to be dead can be revived.

In this way, we contribute to a longer use of the batteries and thus also to the protection of the environment.

We offer cell replacement for all tools (e.g. cordless screwdrivers, lawnmowers, golf trolleys etc.) and have spare parts for a large number of models in stock.

Emergency light batteries

We stock the most common Ni-Cd, Ni-MH and Li-Ion emergency lighting batteries.

If you need a custom-made product, we can produce the required battery packs from a wide range of cell types.
We have the most common cells such as 18650, AA/Mignon, Sub-C, Baby/C or Mono/D in stock. But also special sizes like 1/3AA, 1/2 Sub-C, 4/3A and many more are possible.

AccuPower AccuMotion Extender

Mobile energy supply: Designed with the highest quality and most modern safety standards. The case contains 4 battery packs that provide a total of almost 4,000Wh of energy.


Modern power generators with Li-Ion/Li-Fe batteries. This means you have your 230V socket wherever you need one at the moment.

Cable assembly/ distribution box

Possibility of connecting several battery packs to increase voltage, current and capacity. Of course, in the highest quality.

E-bike battery clear service

E-Bike Battery Care Service AccuPower

For e-bikes, we offer a special e-bike battery care service.

The battery of your electric bike won’t last much longer? Is it deeply discharged or completely defective? We can determine the capacity of your e-bike battery for you using a test machine.

We will be happy to advise you and prepare a cost estimate for a cell replacement. We install brand cells in the existing housing of your e-bike battery. In most cases, stronger cells with a higher capacity can be used, which increases the range per battery charge.

Please feel free to contact us about this.
