Premium Material--The brushless controller shell is made of aluminum alloy,sturdy and durable.it is a wide voltage controller, 48V 60V 72V 84V can be universal, the maximum current limit is 80A(It does not mean that the output current is 80A, it only means that the controller can withstand a maximum current output of 100A. The current output size is also related to the battery and motor.), and it can be applied to brushless motors. Sensitive Control--, good heat dissipation,it can provide steady speed and sensitive control of braking and direction changes. High Performance--The wires and interfaces are durable, and ensure low malfunction of long time use. Easy to Use-- it is Square wave controller,and interfaces have instruction labels on them for your easy installation. (electric lock is key lock，must be connect，if electric lock not connect ，no power.can connect to the throttle have key lock，if throttle not have key lock，electric lock is 2 wires ，can docking together) Application--It suitable for electric bicycles, scooter, electric tricycle etc. 48V-84V 3000W-4000W 60A-100A brushless controller work with hall sensor/not have hall sensor
Name: Intelligent dual-mode brushless controller
Power: 3000W-4000W
Voltage: 48V-84V
Current limit: 60A-100A
Undervoltage: automatic identification
MOS tube: 24mos
Phase: automatic identification (60 ° / 120 ° all can fit)
Brakes: low brake / high brake
Size: 226 * 120 * 70 mm
Brushless controller function：
1.low level brake
2.speed control handle（throttle）
3.cruise
4.hall
5.reverse gear
7.high level brake
8.intelligent recognition（self-learning）
9.phase meter
10.hall meter
11.three speed gear
12.electric door lock（must connect）
13.anti-theft alarm signal（is connect to alarm，if not have alarm，not need connect）
14.anti-theft alarm power（is connect to alarm，if not have alarm，not need connect）
15.multiple data meter
16.motor phase line
17.battery
How to connect controller？
1.connect the motor phase line(color to color）
2. connect the hall line,color to color connect.(if motor without hall line, don't need connect)
3. connect the battery line(red:battery+ , black:battery-)
4.off power,let two intelligent recognition lines connect together,open power,then the wheel will forward or reverse.
(1.if wheel forward ,Separate the intelligent recognition line.
2.if wheel reverse, Separate the intelligent recognition line. Let intelligent recognition line connect together again,if wheel forward ,Separate the intelligent recognition line.)
This step needs to be effective within 2 minutes after the power is turned on. If the timeout occurs, please turn off the power and then turn it back on before proceeding with these steps.
5. connect the controller throttle to throttle and need color to color connect,
connect controller electric door lock to throttle electric door lock
（if throttle not have electric door lock,let controller electric door lock short,
so controller electric door must connect ）
NOTE:when use throttle control speed,two intelligent recognition line must separate.
6.other functions can be connected as needed.
