That's great to hear. UL certification is a starting point. How is that going? What does EU-certified mean with regards to battery safety? I think the sticking point with UL is that you need to know the specific application in order to assess the downstream risks. Are you able to do the UL certification for multiple bikes, or just a specific model? Are you able to get UL certification for multiple different cell brands, or do you need to do a different certification for each type of cells used in the pack? I'm assuming mixed salvaged cells are off the table for UL certification?
