Electric Motorcycle Speedometer MPH CT-22 48v-144v Universal Digital Programmable Display

Buttons aren't labeled and the instructions are in Chinese however the display looks great and functions well. I have yet to set the time as I can't read the instructions but as far as a odometer, speedometer and voltmeter it works as intended

The item arrived almost a month early. I received instructions written in english. The display panel appears to be sealed/water proofed well. I had it installed several days ago and it is working well so far. I will try and give an update in several months.Update May 13, 2020Still works great. At first I was not sure if this would work with my YKL120250FD-B Controller. I contacted QS Motor directly before purchase. I received a very quick response from Vito Ho on Skype.

Does not plug into controller by same company, qs motor

This is a great speedo. It is very versatile and with versatility comes some challenge with programming it. Easy to read and well constructed. Zero Motorcycles uses a customized version of this. I had to fabricate my own mounting bracket out of plate aluminum. Here is a schematic I use for building my electric motorcycles. I have found on the cheap Chinese BLDC controllers to tap in to the motor's hall sensor instead of the phase signal from controller. To program, power on with holding down SEL button. Short pressing SEL modifies values. Long press moves to next character.P 6610 Passwordsetting, current value, default value, description0 180 420 Speed1 180 420 Mileage2 900 640 20% Charge Voltage3 950 690 40% Charge Voltage4 990 730 60% Charge Voltage5 1030 770 80% Charge Voltage6 1060 820 100% Charge Voltage7 900 640 20% Discharged voltage8 950 690 40% Discharged Voltage9 990 730 60% Discharged VoltageA 1030 770 80% Discharged voltageB 1060 820 100% Discharged voltageC 300 deboostD 850 62 0% Charge VoltageE 850 62 0% Discharge VoltageF 1 Charge Memory %R 900 0 Low Charge Warning voltageH 20L 120J 15 30 Battery charge level status interval in seconds
