48V 1,5kWh^*COMMERCIAL BATTERY

SWAPPABLE BATTERY PACK (Si 1.5)

SAME BATTERY. MULTIPLE APPLICATIONS.

No matter the application, power requirements, or size constraints, we have a versatile power solution that fits nearly every need—and can even be seamlessly swapped between different applications! Our 48V 1,5kWh^* swappable battery pack is designed to deliver maximum flexibility with zero maintenance, zero noise, and zero emissions^** at the point of use. Whether you're powering construction equipment, agricultural machinery, or industrial tools, our swappable battery ensures clean, efficient, and reliable energy.

Lower total cost of ownership

Improve asset battery utilisation rates by swapping the battery between different machines.
Accelerate standardisation 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.

* Total energy measured using a 0.2C discharge per IEC 61960-3:2017

** The battery pack is silent, however the application itself may make noise. Zero emissions apply only to the battery pack during operation.
