-
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.
