I have encountered this issue that the battery goes in very tight. So tight in fact that it is a real struggle to get it out afterwards. The key turns well in the locking mechanism, but it is impossible to take the battery out with bare hands. Most of the time need to undo the screws for both mounting plates, wiggle it a bit, squeeze in some flat cone key handle in between the battery handle and pull really hard(risking to break the handle). Also, the lid of the battery compartment wouldn't fit properly at first sticking out to much near the upper mount. I have installed two thin washers between the frame and the mount which helped with the lid placement, but didn't resolve the sticking issue.
That is an issue that wouldn't perhaps bother me as much if not for another problem that I have experienced. On my first ride there was an enormous battery sag - the battery indicator would go down really fast, especially on higher assist levels and then recover again after a bit of standstill or turning off/on. It got so bad in fact that when it was around 70% the voltage dropped so low at a point that the indicator was showing 0 and didn't allow the motor to work. I was pedaling for about 20m without assistance before the whole thing recovered back to 70% and started working again.
After this happened I have installed the 2 washers mentioned above and also re-plugged all the cables in the motor. That did help a lot and the next ride I was still experiencing a bit of sag but nowhere near the amounts I have had the first time.. Personally I tend to think that the issue could be in a poor connection between the battery and the mounting plates socket which creates additional impedance and thus voltage loss. Did anybody experience anything similar or has any suggestion how to diagnose and find the cause of the issue?
