The Dengfu E10 does not use Bafang's batteries either
Hi Karambal
I've read your post and wondered if you managed to resolve your power issue as you didn't post a conclusion after changing so many parts of the system.
The reason I ask is I have a new Dengfu E10 with a M560 motor and C245 V3 display unit that's only been ridden a handful of times and developed a similar problem to yours. Basically I was out for a ride and stopped 15mins for snack whereby the system went into standby. However when I tried to power on the display the bike would not power on and never has again since.
I don't have a Besst Tool but have carried out some rudimentary diagnostics.
The first thing I did was to fully charge the battery even though I suspected it had at least 80% charge but was unable to confirm this at the 6 pin battery output connector as I don't know which pins are shorted out by the on/off switch in order for the battery to provide an output voltage that I could measure. After charging the battery I remembered that the battery voltage could be read at the motor power input XT60 connector, which measured 54v. I was also able to rule out a faulty on/off switch at the same time as I could switch the connector voltage via the on/off switch.
Unfortunately I was unable to measure whether the motor was passing current up to the display unit as the pins on the display input connector (which come from the motor) are very small and I didn't have any probes small enough to push into the connector. I could've purchased an extension cable and cut off one end in order to make a breakout cable but being as the motor system is still under warranty I didn't want to spend anymore money as I suspect the issue maybe a faulty display unit so I decided to contact Dengfu with the issue.
They've been very good and have passed the issue over to Bafang who have agreed to send me out a new display unit which I'm currently waiting for (I'm hoping for not much longer).
Just out curiosity do you or anyone else who maybe reading this know what the 6 pins at the battery output are on the Dengfu CAN-B 48v 17.5ah battery? I would like to reduce the voltage to storage level asap as it's been sitting at a 100% for almost a month and I'm concerned the cells maybe damaged as a result if the voltage isn't reduced to 70-80% soon.
Any help would be greatly appreciated.
