Dapu M155 info

Re: LCD doesn't respond

I think as well I'll look at the voltage difference and ask the supplier if the controller is good with a 52v...

Re: motor/controller/battery compatability

Thanks for the replies. Motomech i am aware of heat generation when the motor is running slowly, but what do you do, I can't ride any faster up the hills.

Re: motor/controller/battery compatability

Thank you amberwolf for a clear and thorough reply. I understand now about the battery which is a Chinese generic Hailong with claimed quality cells. I will try and get hold of the specs for the battery. Before buying the parts i noted that the companies I looked at in China recommended 20A controll...

So i...
