April 4, 20206 yr It is a Lishui controller LSW831, the three pin wire connector should be the throttle then and wire order as I mentioned. But do check the Black/red with a meter to confirm there is polarity between them of 5v. I thought it might be Lishui as the white data plug is usually a give away.
April 7, 20206 yr Author Ok so I've fitted a throttle to the bike. Works fine downhill and on the flat but just dies with any sort of incline!! This is the same as with the pedal assist. Do you guys think the motor might be knackered?
April 7, 20206 yr The ultimate power output is about 230w at the wheel at max current. 12a x 24 = 288w max output from the controller - inefficiency loss of approx 20% watts for the hub and you have about 230w max at the wheel. You should feel the 230w helping out but sounds possibly like the battery isn't able to continuously supply the current under load.

April 7, 20206 yr Hubs don't often cause issues, if it rides ok on level ground then it is ok. The battery is the likely issue though without the bike in front of one we can only take punt at the issue, the power issue up gradients tends to lend it way to being a battery issue and one not in it's best youth.

April 8, 20206 yr Sounds like a battery issue as Nealh says. Earlier you said I also tested them under load. One dropped to 27.1 and then other 27.9. I'm guessing from these results that the batteries are ok?? but you didn't say what sort of load. Load with the back wheel off the ground is trivial, and fairly small for gentle riding on the flat, but much bigger going up a hill.

Load with the back wheel off the ground is trivial, and fairly small for gentle riding on the flat, but much bigger going up a hill. A load can be simulated by lifting the wheel off the ground and applying the brake to a point that the wheel doesn't quite stop, measuring current or watts at this point will indicate the heavy load applied.

I had these results whilst out riding. Uphill, downhill on the flat and in all 3 modes, low medium and high. The voltage didnt drop below 27.1v no matter the incline or the mode. I've got 2 batteries and both the same results. Would have thought I'd be unlucky if both batteries were knackered!!
