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

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

The cells of the system are then fully automatically selected 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 ensure the stability and service life of the batteries.

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

In the next step, the suitable welded connectors are selected and cut to a suitable format.

The welding is then carried out either automatically or manually.

Our semi-automatic spot welding machine (shown) welds battery packs from both sides simultaneously in highest quality. This means that even series production can be processed quickly.

We also offer all our welding machines for sale, please contact us.

Our rechargeable batteries are equipped with a specially developed and installed protection electronics, which protects them against

• Overload,
• Deep-discharge,
• Short circuit
• extreme temperature conditions protects
• and individual cells.

After careful selection of the appropriate protective electronics, these are attached to the battery pack.

Now both the cross-section of the cable for the current of the battery and the respective material of which the cable is to be made (e.g. PVC, rubber, silicone etc.) are determined.

Then the battery pack is sheathed with a so-called GFK insulation.

This material is reinforced by glass fibre and serves as mechanical protection to insulate the battery.

The connectors of the battery pack are assembled according to the requirements.

Afterwards the shrinking of the battery pack can be started.

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 acceptance test is carried out to ensure that the battery pack functions properly.
