What we are doing try to make it more stable as following:
We found the lock core is not long enough to hold the battery. the original one is in golden, we customize a longer one to use now.

And there is some slight gap between battery and the holder, we put one 2 piece of 3M gel to make it holder better and no move. it will be more stable then.

If anyone need some help or support from us, please feel free ask.
I have a Frey Bike on Oder, should be ready to ship soon. I just wanted to thank you for responding to this issue of loose battery. It makes me confident to see Frey responding and I will try the gel tape if needed. I am a firm believer in this tape.

However, I just want to share with you, in an effort to contribute: I have three OTHER ebikes with this exact same battery system by Reention. I have 4 batteries I swap around between all three bikes, 11.4AH x1 20.4 AH x1 17.4 AH x2. None of these batteries are loose in any other of these three bikes that all run 75% off-road. This is also one reason I ordered the AM1000 with Ex-1 so all batteries I own fit all bikes. In my humble opinion as a 62 year old engineer, I would suggest reviewing the dimensions of the machined out section of the rectangular downtube. A few mm too large on this opening when it is machined, will certainly cause a loose battery situation on rougher routes. Again, just trying to help FREY!
