Customised packaging

From individual items to series production AKKU SYS develops and customises battery pack solutions that are precisely tailored to your requirements. As a B2B partner for industry, trade and OEMs, we take care of the entire assembly process - including the selection of suitable cell chemistries (e.g. NiMH, NiCd) and assembly according to technical specifications.

Do you need special connections or have requirements regarding voltage, capacity or design? Our team will implement your specifications precisely.

Manufactured in Germany - for quality you can rely on

We manufacture our battery packs exclusively at our site in Mecklenburg-Vorpommern. This ensures short distances, fast delivery times and consistent quality.

We work with tried-and-tested branded cells and carry out input measurements (cell voltage) and final pack tests during production. In this way, we ensure that voltage differences are recognised and, if necessary, compensated for by recharging. We carry out capacity tests if required.

Your advantages

  • Made in Germany

    Our battery packs are assembled in Germany - with tested branded cells and experienced technical support.

  • Technical advice at eye level

    Our customers appreciate the direct contact: Expert, practical advice for specialists from purchasing, technology or development.

  • High flexibility

    Whether it's a one-off, small series or large order: we manufacture your battery packs efficiently and in line with your needs. 

  • Fast delivery times

    We keep standard packs in stock. We manufacture customised battery and rechargeable battery packs in a short time - thanks to well-established processes, streamlined workflows and high stock availability.

Customised - for a wide range of applications

Our packs consist of several cells that can be arranged in rows or columns as required. for the right voltage and capacity.  

Simply tell us the desired parameters such as capacity, cell type, design and connection type - we will take care of the realisation. 

Typical areas of application for our battery packs are 

  • (e.g. diagnostic and monitoring devices)
  • Safety-critical systems such as , alarm sensors or wireless applications
  • Industrial applications (sensors, drives, control technology)
  • IoT devices (e.g. electronic door locks, sensor applications, data loggers) 

Standardised battery packs

We stock an extensive range of common battery pack configurations, including those based on:

  • Ni-Cd and NiMH technologies
  • Voltages from 2.4 to over 24 V
  • Capacities for a wide range of energy requirements

Customised assembly

Do you need a battery pack with special cell dimensions and connections? We develop and manufacture customised packs - inclusive:

  • , parallel connection or combinations
  • Selection and arrangement of marker cells
  • Capacity adjustment
  • Selection of cell size, design and connection type
  • Shrink tubing

In addition to NiMH and NiCd-We do not assemble cells eitherrechargeable lithium battery packs. 

Replacement and replica batteries

Whether for tools, emergency lights or special technology: we reconstruct existing packs using samples, photos or measurement data - especially for NiCd or NiMH technology.

For suitable applications - e.g. tool rechargeable batteries - we offer a special price from a certain quantity. as a cost-effective alternative to the original. The quality is at least the same as the original.

Important: The housing must be undamaged and non-destructive to open.
