# Elios 3 battery charger replacement

Safety around battery manipulation is important ! Since our last communication on this topic in November 2022, about Elios 3 battery safety, we have heard back from customers with damaged battery charger connectors. 

Therefore, we have improved the battery charger connector design. This new design is now the only one being sent with our products. 

In order to increase safety with Elios 3 battery chargers, we offer free replacement of the old ones.

We strongly recommend only using this new charger design and dispose of the old one.
