Well, I'm no expert but the first thing you need to do is charge the battery. It should be 42v fully charged and 32v fully discharged.
Which switch were you pressing? You can't take any notice of transients on the LCD because the capacitors in the controller will power it for a second or so.Update:
I charged the battery to its full capacity (green light on charger).
After many attempts to switch the bike on, it read 41.4v - which is what it normally showed when the battery was fully charged previously.
What caught my eye was, as I was repeatedly pressing and holding the button to switch the system on, it would turn itself off after a fraction of a second but this time, as it did that, the display faintly showed the battery was 'empty', it had like one bar or zero bars - I couldn't read the voltage.
But mere seconds later I succeeded in switching it on and it read 41.4v as I said. 5 full bars.
Intuition tells me it could be the battery cable that came with the kit, it's a 2 bullet points to 2-pin julet that connects to the controller
(see attached image)
But it could also be the controller?
Also, would I still be able to perform the aforementioned tests if my controller has that julet/waterproof connector?
(image also attached, obviously the battery cable is the one with the 2 protruding pins)
Alas, I don't even have the tool(s) necessary for the job.
I'm puzzled but, since a few days have passed I'm calmer. The kit and the battery are well under warranty since I've only had it since late January - hopefully I'll get it resolved. Fingers crossed.
The one on the LCD display, the button you press and hold to turn the bike on.Which switch were you pressing? You can't take any notice of transients on the LCD because the capacitors in the controller will power it for a second or so.
In that case, I'd say there's a strong possibility that there's a battery connection issue, which will probably get fixed when you install the new controller unless you have a burnt battery connector in the cradle, which happens when you insert a battery that's switched on.The one on the LCD display, the button you press and hold to turn the bike on.
Looking back, I meant button and not switch.

I still haven't heard from Yose since they said they were going to simulate the issues with their engineers.
I cannot recollect ever doing that. My battery stays on the bike as I use it mostly for commuting and I never remove it when I park it there.In that case, I'd say there's a strong possibility that there's a battery connection issue, which will probably get fixed when you install the new controller unless you have a burnt battery connector in the cradle, which happens when you insert a battery that's switched on.
You need to fid the bad connection. If you hanged the LCD with the controller, it'll be between the battery connection to the controller and the cell-pack. If you didn't change the LCD, it will probably be in te cableto it or a wire pulled. Look for where tat wire is squished, including the wire to a separate switch unit. Mine recently got squished by the bell.I cannot recollect ever doing that. My battery stays on the bike as I use it mostly for commuting and I never remove it when I park it there.
And I'm always paranoid and double check I flip my battery switch to 'off' whenever I'm not using the bike.

I was so hesitant about fitting the new controller I only got to it this morning.
Sadly the same symptoms persist with the new controller as well.
Right off the bat I struggled to turn the system on (pressing and holding the on button on the display).
After many attempts of the display going blank, it did come on.
I lifted the bike, and pressed the throttle for a good two minutes.
Battery was full as I'd left it. 43.3v. The display registered 37km per hour as usual (same no load top speed as when I first got the kit).
I let go of the throttle for a bit, then pressed it again; and after about 10 seconds the bike went dead, and the display went blank as I was pressing the throttle.
I waited about half an hour, went to the garage again, pressed the button on the display and the bike worked first time of trying.
I decided to take it for a test ride. And after about 5 minutes of the bike working normally, it went dead again as I was pedalling.
I am perplexed, and I will reiterate I never see any error code on the display or anything, the battery seems to be holding charge.
