A 3 year old Haibike AllMtn Pro with about 19000km on the clock was giving occasional battery problems. [error code 530 and occasionally loosing power] One on the problems appears to have been the state of the frame battery connection terminals. The +ve terminal appears to have lost its coating, which has allowed the underlying copper terminal to start corroding badly, see photo below.

I know the terminal are covered in dirt but there must be some sort of electro - chemical reaction taking place as only one of the terminal is badly corroded, maybe something that anyone with an older Bosch powered bike should look out for.
I do transport the bike on a tow bar mounted carrier in all weathers and wonder if maybe the salt laden spray in winter has maybe exacerbated the problem. Have now bought a motor cover to keep the battery terminals clean while the bike is being transported, will be interesting to see if it makes any difference. I suspect that this may be just be a part that needs replacing every few years.
Fortunately Adrenalin ATV had the part in stock, not a particularly difficult job to replace though does require the motor to be dropped out.
The next problem to figure out is why my 400W/h power pack is as dead a the proverbial Dodo [gave up the ghost while waiting for the spare part to arrive, my 500W/h battery is OK].
