On my 2018 Riese & Muller Delite Mountain with dual batteries, both batteries can be changed in situ on while on the bike 85% in one then 85% charging the second battery, then simultaneously both to 100%.An update on the Range Extender questions. I have just taken delivery of a Haibike Allmtn 5 with the Performance Line CX 85Nm motor and the range extender.
Myself and the bike dealer found out that you can not charge the batteries from the in-frame charging point. You have to charge them from the charging port in the bottom of the range extender bottom battery holder. This means that the in-frame battery connector does not charge even the internal tube battery. It's not a problem - but anyone thinking of buying the extender should know this.
On my Trek Allant 9.9s with a 635 internal battery and the external range boost that hosts a 500 powerpack, both batteries are charged in the same manner.
What you are experiencing is either a specific problem with your bike and a glitch in the Haibike set up for range boost.
