It only dawned on me yesterday. This is a motor that I replaced the 3 hall sensors in. When I tested it after I made the repair, it rotated on throttle and I was happy. I never thought to check the speed hall sensor. I think this is faulty also. I have ordered a complete replacement hall sensor...

Just pulled these from the manual. Must be new to the lcd8

My Q128C has a 48V battery and the settings I am using are the same as what I have on a lcd3 on another bike. Do you think experimenting with P1 and setting speed to 25km/hr should solve the zero speed when freewheeling? Should the display not get speed signals from the wheel speed sensor...

Looking for your help again please if you wouldn’t mind. I have a Q128C(lower of the 2 speeds available) motor laced in to a 27.5 inch wheel which is close to a 28 inch with the size of the tyres. I am pretty much all set up now and have taken it for a road test. The pas works ok but I’m not...

No. Haven’t tested it yet. Slowly making my way through it. I bought a mavic rim to lace my motor in to and it is a pain to get the tyre on to it. I finally got it on but have given up for the night. Too tired. Tomorrow’s another day.

Just finished. All seems good.

Thanks nealh. Very helpful as always. I will leave a little length on the wires then solder and heat shrink.

I have started the process of wiring my pas directly in to my integrated controller solely for the purpose of making it look neater. I purchased the pas separately and has different coloured wires to the wired cable which I will be removing. The controller has black(marked G), red(marked TH)...

Just to come back with my findings. The voltage disappears when a load is put across the discharge contacts. I went ahead and temporarily set everything up and it worked fine. Charging the battery will be my next step and hopefully will be ok. I would like to thank everyone for their input and...

Thank you vfr400. That would be a huge relief if that’s the case. I haven’t put the bike together yet but the best way to test it, I suppose, is to test it. I did notice that when I tested the led indicators, as Woosh suggested, the voltage dropped to 1V but rose again when the test button was...

Thanks Nealh. I swapped it now just to check but made no difference. It’s basically a different end of the same wire.

Ok Woosh. Thanks for taking the time.

Just for full disclosure. There are a pair of white wires which are for the on off switch which I connected correctly. This switch also has another two wires( black and red) which are for an internal light to indicate when the switch is on. I connected the red and black from the bms to these...

Thanks for the reply Woosh. No I don’t have any load at the discharge port. I have another battery pack that I bought and when the power switch is off on that one there is no voltage between + and - at the discharge port.

Looking for some help again please. I finally got the courage to build my own battery. It all went well and has been a great learning experience. I wired in my second bms this evening as I thought I blew my first one. I followed the suppliers wiring diagram but I’m getting almost full pack...
