About a year after getting the battery cells of my electric bicycle changed in winter 2024, it starts turning off when I drive over uneven terrain.

I thought it was a fitting issue, because the rubber seal had got loose... Nope. One connector is basically falling to pieces.

Battery is a TranzX PST BL15. Bicycle is from 2018.

Please don't tell me this is the end of the road (ಥ﹏ಥ)

Closeup of an e-bike battery's connectors. One of then is... not great, the metal breaking and degraded.

this is just my local shop example part: https://ebikes.ca/ebike-parts/battery-stuff/battery-accessories/con-dt-5pin.html

you will probably want to find whatever shop it most convenient for you, and get the piece with the same number of contacts.

you might also be able to bridge unused pins on the battery and battery receiver. I wired mine which is 6 pin to be 3 + and 3 - to not have this failure from just one pin damage. Most I have disassembled the extra pins are not connected and it just uses the outer two as single + and -.
