Hi, long time reader first time poster - please be gentle!
I built my ebike with the Bafang mid drive BBS02 750W and for the last 400 miles in 4 weeks of owning it has changed my life. I love it.
Today, I went for a ride with a fully charged battery. Less than a mile into it, I get a 30H code. Turned it off and on again. This happened twice as I was riding back. Then, after a stop, zero pedal assist, it seemed to display a high power demand briefly until I put the anchors on. It lasted less than a second. No throttle was used.
Now, I have a display but no power to the motor (30H is no longer showing). Interestingly, the voltage displays 52v or so, but the battery indicator is red and showing discharged (it is fully charged).
Occasionally on the battery itself, the power LEDs remain on and won’t extinguish without a firm tap. I’m not sure if this is related!
Overall I only ride in fair conditions, dry. I don’t cruise on the throttle apart from the odd blip at low settings.
I’ve checked the connections (I had previously used dielectric grease and liquid electrical tape to seal) - it’s all clean, pins and straight and wires aren’t taught or pinched. I’ve disconnected and reconnected it all.
I’m starting to think it’s a controller issue. Is anybody
Able to offer a little advice? I’m starting to feel a bit out of my depth, but happy to learn with some guidance!
