Due to high workload, we cannot accept new battery rebuild jobs for the foreseeable future.

Batteries - Made in Norway 🇳🇴

Concept, design, prototype, production, repairs.

Batteries for golf carts, forklifts, e-bikes, small EVs, wheelchairs

and more — giving your eVehicles a second life! 

About Battkomp

Battkomp designs, produces, and repairs li-ion batteries in the 0.5 to 10 kWh range for mobility applications. If it moves, but smaller than a car - we do it!

Design and production

Battkomp can produce batteries in any shape or size, complete with housing, safety systems, appropriate connectors, and communication systems to ensure complete compatibility with the host device.

  • Help your product development by providing custom batteries for prototypes

  • Give older battery-driven products a new life by converting from lead acid or NiMH to lithium

  • Provide replacement batteries for products where the OEM is no longer available

The battery production services are targeted towards customers who wish to order at least 5-10 batteries.

Repairs for individuals

We repair Bosch, Shimano, EVORIDE e-bike batteries. Broken connectors, bad control boards, etc. We do not rebuild worn-out e-bike batteries for the time being due to high workload.


  • The cost of a repair is 2-3000 NOK.

  • Sending possible by Posten (200 NOK for return shipping)

  • All work is done in our Oslo workshop

Repairs for businesses

No design is without a weakness. We offer troubleshooting and repair solutions for batteries failing prematurely.

We are battery repair service providers to Bolt, Buddy Electric, and Oslo Kommune.



Why: Have fun and engineer neat things that make a difference.


How: We make e-mobility live up to its promise of sustainability.


What: We offer new designs, rebuilds, and repairs for mobility batteries.


We strive to grow into a battery factory that builds high-quality, high-performance batteries for demanding mobility applications.

We cover the module design, assembly, housing, and battery management part of the battery value chain. We are interested in excellent engineering and advanced automated production machinery.

We want to run the whole business from Norway, betting on automation instead of cheap labour, quality over quantity, reliability over price, local over foreign.

Our insight is that EV waste could be drastically reduced if:

  • Product lives were extended through up-to-date batteries

  • Simple problems were cost-efficiently repaired

  • Bottlenecks were eliminated:

    • Lack of modern compatible batteries
    • Proprietary connectors, communication protocols, housings
