Self checking from APP, Battery X

Recommended Posts

I bought a new DYU D1 from a seller on Amazon.  Opened the box and assembled it.  I turned on the power switch and the dashboard did light up showing a full battery. I also put it on charge.  The  LED turned green.   I sat on the seat and advanced the speed control.  It wont run. Should it have run without the Ancheer APP? 

I thought perhaps it needed to be unlocked via the APP.  I installed the APP on my smartphone.  Set up the password and it is now unlocked.  But it still wont run.  I ran within the APP the Self Checking.  All items checked were good.  Except the battery failed with a X.  The seller is stupid and is wasting my time trying to diagnose it.  Amazon requested they send me a replacement but they insist on diagnosing it.  They are not the factory.  They are sales people wasting my time. I sent them a video and  a screenshot showing the Battery X.  Its now  2 days and haven't heard from the seller.  Tonight I will ask amazon for a refund.  But perhaps you, THE FACTORY have a suggestion for me to get it going before I insist on a refund.

 Can you suggest a way to get it going? Perhaps a master reset within the APP?

It need some tests before understanding where the problem is:
1. Chek if the problem lies in throttle. 
2. Is it set as none zero speed start
2. Is the electricity cutting brake is broken. Can you provide photos?

I checked the wire to the motor and it looks fine.

I double confirmed the throttle is not sticking and is all the way turned off.

In the Ancheer APP downloaded on July 20, Start is set to None Zero start

Find attached pictures of the wire to the wheel and the rear brake assembly.

When I squeeze the brake handle there is much free play (travel) before the brake applies.

Can you describe where the brake/motor cutoff adjustment is on the handle bar?  Maybe I can back it off.  Which direction to turn it it?

Further tests:

I measured the battery voltage at the charge port.  It reads 42.1 volts.  The handle bar display also shows a full battery.

Within the Ancheer APP,  Self checking  displays Battery test Failure with an X.  But in the app I select BASIC.  There it shows a battery voltage of 8.9V.  Is that right?

Lights and horn work normally.. It just wont run.

How do I test if the brake switch is not the problem?  How do I test if the throttle when closed is fully closed? )

Dear, Thank you for your informaiton. Our brake is power-off brake, if the brake doesn't rebound fully, then the throttle won't run,plz check whether the brake rebound fully already.  For the volt, informaiton in APP is only correct when bike power is finished full charged. To better and quicker solve your problem, plz contact me by my whatsapp: +86-19874721203

Brake lever is fully off.  I don't understand or have used Whatsapp? How do I use it?

Is there a link to a download you can send me?

How can I get support from the F-W factory tech?qz45j9ek.bmp
