I got a Cannondale Treadwell Neo Remixte and want to use a range extender battery on it. It uses the Mahle ebikemotion hub drive. The problem is that when I mount the range extender battery on the seat tube it is a few inches too far away from the charging port for the internal battery. Communications with Mahle and Cannondale have been amazingly frustrating and unproductive--each placing responsibility on the other and basically saying we don't have an extension so tough. I am a bit hesitant to just cut the battery to battery cord on the extender but wondering if I could do that and just add some length to the cord. (reasonably competent at wiring/soldering). Any suggestions? The availability of the extender was a consideration in our purchase and quite disappointed that neither of the companies has any interest in making it work on that frame.
Need longer cord on Mahle ebikemotion x35 range extender battery

This?
Do a search string choose images.
4 pin mahle battery connectors
Next go to TE Connectivity. If you can’t match from images of the above search. I don’t believe the connectors are proprietary. Patience searching and a digital caliper for the win.

Where were you able to purchase the range extender in the US? I have a Cannondale Treadwell and cannot locate one. Thanks for any help
I bought two of them from Contender Bikes in Salt Lake City. I just checked their website and they show as unavailable. Sorry. I am pleased to report that it worked well on the bike. At a low level of boost it kept the bike battery charged. The other appeal of having the extender is to be able to charge the extender while driving in our rv and then let the extender recharge the bike battery.
I resolved the extension issue by cutting the cord and splicing in an extra length.

Yes quite pricey but integrate well.
How did you cut it without making short circuit?

Not to be sarcastic, but if it’s not clear you perhaps ought not do it yourself. But there are good tutorials on splicing and soldering on YouTube. Maybe you have an acquaintance that has the skill set?
Hoping someone from this older post can help... I recently purchased a new but older stock Treadwell Neo 2 with a Hyena internal battery (model BP-B250) and the connector attached. I have gone back and forth with Cannondale, Hyena, and Mahle and have not been able to locate a range extender that I can purchase for my bike. People above mentioned a pricier option, I'm open to anything at this point but not sure what will work! Thank you! Irene

@stompandgo can maybe help you...
Thanks, I did purchase that one from the local Trek store after some research, but Trek couldn't figure out the connector cable that would work with my port. Cannondale/ Hyena/ Mahle weren't any help. Do you know which cable would work with that extender/ my port?

Have you taken it to a Cannondale dealer? Have they opened a ticket for you?
Yes, I took it to Conti's where I live in VA, the closest Cannondale dealer (they don't seem to have someone too familiar with e-bikes), and I've spoken many times with the shop I bought it from (a place called Public Lands in PA). They've both reached out to Hyena and Cannondale and neither entity seems to be clear on an extender that will work, they keep sending me back to the other company. Since people on this forum seemed to have had success with this bike and an extender, I was hoping to understand what worked for others.

I've heard of Public Lands, and they are legit. If Cannondale does not have an answer, then they don't officially support a range extender for your bike. Something will have to be custom made. If the voltage for the Trek RE is correct, then it's at least wiring, but it could be more. The discharge rate of each battery may need to be managed electronically.
