Features 1、Not divide lead acid battery, li battery, water battery, dry battery. 2、Not divide all models of electric bikes(12V to 99V general), can automatic identified, real time display. 3、Eliminate analog electric quantity display(several small lights), real time digital voltage display, intuitive, convenient, can accurately determine the remaining electric quantity, travlled distance. 4、Judge electric bike fault by voltage number, get twice the result with half the effort. 5、Made of premium plastic material, sturdy, durable and long service life. Specification Item Type: Electric Bike Handlebar Switch Model: S Series(5V-99V Automatic Identification Electric Bike Voltage) Material: Plastic Color: Black Efficiency: ≥98% Hall Level: Linear Hall, Premium Rubber, Imported LED Digital Display Light Working Voltage: Handlebar DC0.8V-4.2V Electric Quantity Display: Not Divide Lead Acid Battery, Li Battery, Not divide Voltage, Automatic Identification(12V，24V,36V,48V,60V,72V Electric Bike Can Used Directly, Some 84V Electric Bike Can Also Used) Weight: Approx. 176g Battery 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 full charged 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 handle 1. Features The voltage digital display turn full replaces 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 the lithium battery is damaged by turning the real-time voltage value, which is convenient for after-sales! 3. You can judge the quality of the lithium battery by turning the voltage value, which is convenient for the factory to purchase qualified lithium batteries! 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 point 2. Matters needing attention Non-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 burn 3. 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 higher 24V electric car, the highest voltage is about 29.4V, the lowest is about 21V or a little higher 36V electric car, the highest voltage is about 42V, the lowest is about 29V or a little higher 48V electric car, the highest voltage is about 54.6V or 58.8V, the lowest is about 39V or a little higher 60V electric car, the highest voltage is about 72V, the lowest is about 49V or a little higher 72V electric car, the highest voltage is about 84V or a little higher, the lowest is about 60V Higher 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 List 1 x Electric Bike Handlebar Switch 2 x Key
