Description: The digital data display, not that common analog signal display, which can accurate judge rest battery level and rest distance can indicate vehicle error according to voltage.Fit for many types of battery such as lead acid battery, lithium battery, water battery and dry battery.Thisthrottle indicates battery level by digital data display, you can judgeyour rest battery level according to your battery voltage, can also check your battery condition after you charged it full. It is a universal throttle for electric bike, scooter , tricycle, and other electric vehicle.Features:1. Universal voltage, fit for 12-84V electric bike or scooters, can identify voltage automatically, timely indicating. (12V, 24V, 36V, 48V, 60V, 72V electric vehicles can be used directly, part of the 84V electric vehicles can also be used.)2. By turning the real-time voltage value can accurately determine the amount of the remaining amount of electricity.3. To avoid traveling on the way without electricity and accurate judgmentof the lithium battery is damaged.4. By turning the real-time voltage value can accurately determine the judge the quality of lithium battery.5. Automatic to identification electric vehicles' voltage under 100V, universal used and real-time display.Specifications:Material: Aluminium Alloy + RubberColor: Golden, Silver, Red, Blue (optional)Wire Length: approx. 1.8m / 70.9"Type: 3 gears switch, high speed, middle speed, low speed (Adjust the speed of electric car, need controller to support)Compatible With: Suitable for 12V-99V Electric BicycleFitment: Fit for 22.2mm diameter handleWorking Voltage: Throttle DC0.8-4.2V, battery level indicator, 12-84V automatically identify. Application for any battery such as lithium battery , lead-acid batteryCompatible With: Universal throttle for electric bike, scooter, tricycle, and other electric vehicle7 Wires:Yellowis for power positive, usually connect with battery power + 24V 36V 48V3 throttle wires:Redis for throttle positive+ 5VGreenis for twist throttle signal wireBlackis for throttle negativeThe other three white blue and brown is for gears 3, please make sure your controller has 3 gears wireWhiteis for high speedBlue is for middle speed shared lineBrownis for low speedPackage Included:2 x Handlebars (1pc right handle, 1pc left handle grip)1 x 1.8m LineNote:1. Please notice that if your electric vehicle's controller doesn't support speed regulation, then this speed control switch has no effect.2. When installing the non professionals, please pay attention to the line order, can not be connected to the wrong line, otherwise it is very easy to cause the burning of Holzer and LED tube.3. Please allow 1-3cm error due to manual measurement. Thanks for your understanding.4. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please in kind prevail.5.Please note that the product button color is shipped randomly.Common sense for battery voltageDifferent battery materials, new/old condition of battery, and different controller data make battery voltage reflects differently. Please check your battery voltage data according to your battery. The maximum voltage indicates full charge. The low voltage indicates that the battery is exhausted.12V electricbike maximum voltage 12V, min voltage 9V24V electricbike maximum voltage 29V, min voltage 21V36V electricbike maximum voltage 42V, min voltage 29V48V electricbike maximum voltage 54V, min voltage 39V60V electricbike maximum voltage 72V, min voltage 49V72V electricbike maximum voltage 84V, min voltage 60V.
