Features1Not divide lead acid battery, li battery, water battery, dry battery. 2Not divide all models of electric bikes(12V to 99V general), can automatic identified, real time display. 3Eliminate analog electric quantity display(several small lights), real time digital voltage display, intuitive, convenient, can accurately determine the remaining electric quantity, travlled distance. 4Judge electric bike fault by voltage number, get twice the result with half the effort. 5Made of plastic material, sturdy, durable and long service life.SpecificationItem Type: Electric Bike Handlebar SwitchModel: S Series(5V-99V Automatic Identification Electric Bike Voltage)Material: PlasticColor: BlackEfficiency: 98%Hall Level: Linear Hall, Rubber, Imported LED Digital Display LightWorking Voltage: Handlebar DC0.8V-4.2VElectric Quantity Display: Not Divide Lead Acid Battery,LiBattery, Not divide Voltage, Automatic Identification(12V24V,36V,48V,60V,72V Electric Bike Can Used Directly, Some 84V Electric Bike Can Also Used)Weight: Approx. 176gBattery knowledge:This turnbar uses digital display voltage to directly obtain the battery power. Please determine the remaining battery power according to your own electric vehicle battery voltage V number. You can also determine whether the battery is damaged and slightly damaged by the fullcharged voltage situation. Found, repaired early. In the past, the power indicator light was used to simulate the power display by collecting the battery voltage (taking the 3 lights display of 36V battery as an example, 39V to 42V shows full power, all lights are on, one light is off from 37V to 39V, the second light is off from 34V to 37V, 31V to 34V, the last under-voltage light is on, this method can blurred, because it is impossible to determine how much V power is interior, and this method of collecting voltage has not been adapted with the advancement of battery technology), because the battery material Different, different processes, and different battery discharge platforms, which leads to the uncertainty of the way of collecting voltage. The digital display of the voltage completely solves this problem. The battery voltage is collected in real time and displayed in a digital real-time display. It is easy to judge how many miles you can use by the number change and whether the battery is damaged. .Instruction manual for voltage digital display handle1. FeaturesThe voltage digital display turn fullreplaces the analog power display turn, 12V to 84V electric car automatic recognition, real-time display voltage, accurate judgment of battery power, convenient and practical!1. By turning the real-time voltage value, you can accurately determine how much power is left, which is convenient for customers to drive!2. You can accurately determine whether thelithiumbattery is damaged by turning the real-time voltage value, which is convenient for after-sales!3. You can judge the quality of thelithiumbattery by turning the voltage value, which is convenient for the factory to purchase qualifiedlithiumbatteries!4. Automatically identify electric vehicles with voltage below 100V, which can be used universally, which is convenient for factory purchase, saving capital cost and management cost!5. There are 4 wires for the common electric display turnbar, which is convenient for workers to install and save working hours!6. Digital TV display is not available in the current market, can seize the opportunity and become a new selling point2. Matters needing attentionNon-professionals should pay attention to the line sequence when installing, and cannot connect the wrong line, otherwise it will easily cause the Hall and the LED tube to burn3. The basic parameters: (according to different battery materials, different old and new, different batches, voltage v number will be different, please test a few times, you can get your own electric car battery parameters,12V electric car, the highest voltage is about 12.6V or slightly higher, the lowest is about 9V or slightly higher24V electric car, the highest voltage is about 29.4V, the lowest is about 21V or a little higher36V electric car, the highest voltage is about 42V, the lowest is about 29V or a little higher48V electric car, the highest voltage is about 54.6V or 58.8V, the lowest is about 39V or a little higher60V electric car, the highest voltage is about 72V, the lowest is about 49V or a little higher72V electric car, the highest voltage is about 84V or a little higher, the lowest is about 60VHigher voltage electric vehicles are already equipped with voltmeters.Installation method: three turn handle wires, red turn handle positive pole, black turn handle negative pole, green turn handle signal line, yellow alone is the power supply positive line,Package List1 x Electric Bike Handlebar Switch2 x Key
