Si Series - Swappable Battery Packs

No matter the application, the power needs, the dimensions … we have a power solution that fits nearly every application - and can even be swapped between them! With zero maintenance, zero noise and zero emissions at point of use. We are powering the future with our 48V 1.5kWh* swappable battery!

  • Lower total cost of ownership (TCO) - Improve asset battery utilisation rates by swapping the battery between different machines.
  • Accelerate standardization processes - Easy swapping enables interchangeability across multiple brands and applications.
  • Reduced equipment downtime - Easy latch system allowing to charge one battery while another is in use. Robust aluminium die-cast casing for extra reliability. And literally no maintenance.
  • Fewer batteries, better sustainability - Standardization reduces the number of batteries in production. This can also reduce emissions and noise pollution while minimising the need for mining new materials.
