Hi all,

Firstly, thanks for reading.

Right, Ive ecently bought an Orbea Gain for an absolute steal, which included a Range Extender.

Anyway, the bike is faultless and had it battery replaced recently (currently 41.9v fully charged).

But I have an issue with the range extender (RE).

The RE turns on, charged the battery for 30 seconds and then turns off again.

It doesn't even get detected by the app, oddly.

But checked the voltage on RE and got a reading of 41V, which is the same as the bikes internal battery.

So, long story short, ive taken the RE to a store who said the cells are dead - and wouldn't bother looking at it. They claim it says it is full.

Few things, though, how can cells be dead if it's charging and would charge the bike if I just keep turning it on again...

Anyone else had this issue, any way of fixing it or is it just an expensive paper weight?

Regards,

Jordan

The range extender has been problematic for a lot of people. The Electric Bike Review has some interesting posts. It seems to me like very bad software. I'll put a post here of someone who managed to resynchronize his, which may or may not help.
