Package Dimensions:14 x 9 x 3 cm Battery common sense: For this display Battery is measured by voltage. this throttle can work for any electric bike under 84v with lead acid battery, lithium battery, water battery, dry batter and so on. The throttle with automatically identify voltage. Due to the difference of battery material, battery conditions ( new or old, ),controller data , the battery voltage reaction will be different, so the data bellow will have deviation. Customers please check according to your battery to get your battery data. Spec: Condition: 100% Brand New Item Type: E-Bike Voltage Display Material: plastic Color: as picture shown Model: S series (5V-99V automatic identification of electric vehicle voltage) Efficiency: 98% or higher Hall grade: linear hall high quality rubber imported LED digital display lamp Working voltage: turn DC0.8V-4.2V Power display: regardless of lead-acid battery, lithium battery, regardless of voltage, can be automatically identified (12V, 24V, 36V, 48V, 60V, 72V electric vehicles can be directly used, some 84V electric vehicles can be used) Terminal length: 1.8m by default Green is for throttle hall signal, red wire is for throttle +5V, black is negative wire; please connect according to controller function wire, U can not just match same color wire, if wrong connected that will damage your controller and throttle. 4 wires : yellow is for voltage display wire, connect with electric bike power positive. 5 wires: blue wire connect with controller power lock output wire, yellow wire connected with controller electric switch input wire power positive, 6 wires ; yellow connected with power positive, blue wire and white is is function wire(can work as reverse switch, horn switch, cruise switch, power lock and so on) 7 wires: yellow connected with power positive, blue is share wire, middle gear for 3 gears , white is high gear, brown is low gear.
