Has it been consedered as to why the battery is not charging? Faulty charger, dead battery cells, wire within battery has come loose, capacitor has failed? All these things are eminently fixable. And it would be much cheaper to fix than buy a new battery.

Hi PatW, Couldn't help wonder what you meant when you said your "battery had died". What were the symptoms? Is it not fixable?

Thanks for advice Neath

Are Bafang and Yose Power 36v motors compatible? The reason i'm asking this is that i've just acquired a Bafang 36v rear wheel hub motor. The plug from the motor looks the same as the one coming from my Yose Power 36v rear hub motor. Can I simply swap wheels and plugin, or am I going to meet some issues?

Photos showing the blackened resistor and the two capacitors, one with a split plastic cover. The assumption is that the resistor overheated and transferred the heat to the capacitor causing the plastic to split in the process.

I burnt out the previous motor after climbing a long and very steep hill. The heat generated by this probably contibuted to the eventual failure of capacitor. Ive no idea if the capacitors had a suitable voltage rating. I guess they did as the controller came as part of the kit.

What do you want me to say? Visibly damaged capacitor was replaced. Ebike working fine now.

It looks like the heat from the adjacent resistor (which looks like a wire link), which was excessively darkenened by excess current, melted the plastic covering of the capacitor and caused the top of the capacitor to expand. There was no visible damage to the mosphets.

They were visibly damaged

My ebike was failing when going up steep hills. I would switch it off for 20 seconds and then the motor would start again. This failure slowly got more regular and worse. Yose Power said the motor was faulty and, as it was still under warranty, they sent a replacement. I finally fitted the new motor and set off, and after 100 metres it failed. And this time it wouldn't re-start. This got me looking at the Controller ( KT36ZWSRT-01). The two capacitors on the circuit board looked suspect and my friend, who is a deft hand with the soldering iron, replaced them. My ebike is now fully working again. Cost of components less than a fiver. I am now looking for a wheel so I can utilise my spare motor
