Hi could really do with some advice. I've got a 24v setup ive been tryin to get running for some time now. I started buy building my own battery pack using panisonic 18650 2800mah cells and used 60 cells in groups of 10 x 6 to give me 24v 28ah using a BMS to control it. So after building the battery I brought a 24v 180w hanli hub motor from ebay and then brought a NEW 24v kit from Panda bikes so I would have the rest of the parts I need. last week I decided to have a go at testing it and found that after running the bike for only a ouple of mintes the hub and controller get very hot!!! this cant be right. please can somebody give me some advice

I'm new, and others more experienced will most likely chime in to narrow down the problem, but is it possible you built the battery 10s6p and have a 36v 17amp pack .. 10x3.7v = 36v - 2800mah x 6 = 17amp .. did you check the pack voltage?

Hi thanks for the reply, ive checked the voltage and it is reading 24.5v and I made sure I built the battery correct :-) there is 6 backs of 10 cells 6 x 4.1v and 10 x 2800 = 28ah . I'm Very sure the battery is not at fault I think it could be I've not wired the motor or hall sensor correct?

You may have seen these links. I only have wired up two motors and the instructions were correct, which doesn't always happen, I guess.

The message is sometimes you can get the sensor wires crossed, and it still runs, but will be noisy, rough, or rrun hot.
