Hi there @TanteMuffin ,
I come from Germany and it’s possible that I can assist you.
First, let me ask, why do you need a battery? How old is your EMO, and what is the order number?
Could you please provide more details about the issue you’re experiencing? Is it related to your EMO’s battery? Can you tell us more about how long the EMO’s battery lasts during regular activities, such as just walking around?
best regards…
