NoteThe accelerator is marked as 48V, and the default is also 48V. However, both 24V, 36V, 48V, and 60V and 72V can be used, and the buyer needs to set the voltage themselves.This is a throttle that can display speed and mileage,suitable for most brushless controllers and has a wide range of applications.The voltage is 24V 36V 48V 60V 72V Universal, which can be set according to the buyer's needs.(First press and hold the M-key, then turn the key to start the machine,then long press and hold the M-key until the voltage parameter flashes,then short press and hold the M-key to switch the voltage until the desired voltage is reached,then long press and hold the M-key until P02 flashes, then shut down and save the parameter settings.)The throttle line 150cm, hole diameter 22mm.24V 36V 48V 60V 72V Electric Bike Scooter Throttle LCD Display ShowSpeed and Mileage and Battery Power1.phase speedor name call Pointer meter, P04 can set the speed measurement mode,where 0001 represents phase speed testing and 0002 represents hall speed testing2.key lockor call electric lock or call electric door lock,If the key is turned off and the LCD page is not turned off,it indicates that the key lock wiring is reversed and needs to be swapped before wiring.3.throttleif connect to controller throttle not work,meaning throttle not connect rightnormal need red to red,green to green connect,black to black connect,but different controller,throttle have different color,Buyer needs to debug themselveshow to connect this throttle?1.phase voltage speed is connect to controller Pointer meter or phase voltage speed2.key lock is connect to controller key lock or name call electric lock,electric door lock3.throttle is connect to controller throttle wires,need color to color connectif throttle interface not match controller interfaceneed cut off interface to connect.this need buyer DIY it.if wires interface not match controller interfaceneed cut off interface to connect.this need buyer DIY it.Guidelines for setting LCD instrument parameters:Press and hold the M key to turn on the power and enter the parameter setting mode:"Short press the M key to quickly switch to the upper row of P characters,first displaying P01 in descending order; * Long press the M key for more than 3 seconds,the lower row of numbers will flash, and then short press the M key to change the parameters,Hold for 5 seconds to save the current parameters.Code:P01 can be set to 24V, 36V, 48V.60V, 72V voltage, with a default value of 48VP02 can be set from 10 to 150, with a default of 100P03 can be set to 90-130, with a default of 100P04 can set the speed measurement mode, where 0001 represents phase speed testing and 0002 represents hall speed testingP05 can set wheel diameters of 8,10,12,14,16,18,20,22,24,26,28,29, with a default of 14 inchesP06 can set the number of magnetic steel from 1 to 99, with a default of 30P07 can set the battery voltage display coefficient to 95-105, with a default value of 100P08 can be set with three gear functions: P08=0 without gear, P08=1 defaults to first gear, P08=2 defaults to second gear, and P08=3 defaults to third gear Default is 0P09 mileage reset: After entering the parameters, long press for 3 seconds, the mileage flashes, and short press 10 timesSwitch between P10 kilometers and miles, with 0001 representing kilometers and 0002 representing miles
