Description: 1 lead acid battery, lithium battery, water battery, dry battery . 2 is not divided into various types of electric vehicles (12V to 99V general), can be automatically identified, real-time display. 3 eliminated analog power display (several small lights), real-time digital voltage display intuitive, convenient, can accurately determine the remaining power, mileage??Judge electric vehicle fault by voltage number, get twice the result with half the effort. Green is for throttle hall signal, red wire is for throttle +5V, black is negative wire; please connect according to controller function wire, 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. The above is common wiring way, if need made to order please connect with salesperson. 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. 1. The real-time voltage value can be used to accurately judge the remaining amount of electricity, which is convenient for customers to drive 4, automatic identification voltage under 100V electric vehicles, can be general, convenient for factory procurement, save the cost of capital and management costs 5. There are only 4 wires for ordinary electric display, which is convenient for workers to install and save time. Basic parameters: according to different battery materials, old and new, different batch, the number of voltage v will be different, please test a few times, you can get your electric vehicle battery parameters. For 12v electric bike, maximum voltage is about 12.6v, mini is about 9v or higher, For 24 electric bike, maximum voltage is about 29.4v, mini is about 21v or higher, For 36v electric bike, maximum voltage is about 42v, mini is about 29v or higher, For 48v electric bike, maximum voltage is about 54.6v, /58.8v, mini is about 40v or higher, For 60v electric bike, maximum voltage is about 72v, mini is about 49v or higher, For 72v electric bike, maximum voltage is about 84v, mini is about 60v or higher, For other electric bike with higher voltage there should be a voltmeter installed. Type : E-Bike Thumb Throttle Color: black Size : 2m Material: plastic Product includes: 1pc E-Bike Thumb Throttle Note: 1.Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
