Unanswered Range extender bosch

[Hofi]

Hello, question for a range externder to a haibike, (1x Bosch Powertube 625 Wh + 1x Bosch Powerpack 500Wh) after finishing the batteries of the two connected ,I can change an empty battery and connect the full one to a chary in the bag (625Wh) something will happen, or will I get an error, will the engine stop or other problems?
Thank you

You can change them as you want to, even if one is empty. Bosch do not use both battery at the same time, it does not connect them together but switches between them as you ride.

It will use a bar on 1 battery and then switch to the other battery and so on.

No problem of disconnecting a battery, and I've never had an error
