Feature: 1. No distinction is made between lead‑acid batteries, lithium batteries, water batteries, and dry batteries. 2. It does not distinguish between various types of electric scooter (12V to 99V universal), which can be automatically identified and displayed in real time. 3. Eliminate the simulate electric quantity display (a few small lights), real‑time digital voltage display, intuitive, convenient, can determine the remaining power and mileage. 4. Judging the breakdown of electric scooter by voltage figures, high efficiency. 5. Professional manufacturing, stable performance and high reliability. Specification: Condition: 100% brand newItem type: Electric Scooters Throttle GripMaterial: plasticColor: blackWeight: Approx. 191g Model: S series (5V-99V automatically recognizes the voltage of electric scooter) Efficiency: ≥98% Hall grade: linear for Hall, high quality rubber, imported LED digital display light Working voltage: Throttle Grip 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 scooter can be used directly, some 84V electric scooter can also be used)This throttle grip uses digital display voltage to directly obtain the battery electric quantity. Please judge the remaining battery electric quantity according to your own electric scooter 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. Before, the power indicator light was used to simulate the electric quantity display by collecting the battery voltage (take 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, and the second light is off from 34V to 37V, The last undervoltage light from 31V to 34V is on. This method can be blurred, because it is impossible to determine electric quantity. This method of collecting voltage has not been adapted with the advancement of battery technology), because the battery material is different, Different processes and different battery discharge platforms lead to the uncertainty of the way of collecting voltage. The digital display of voltage solves the problem. The battery voltage is collected in real time and displayed in a digital real-time display. It is easy to judge by digital changes How much mileage can be traveled and whether the battery is damaged.Voltage digital display throttle grip instruction manual 1. Features Voltage digital display throttle grip completely replaces analog electric quantity display throttle grip, 12V to 84V electric scooter automatic identification, real-time display voltage, accurate judgment of battery electric quantity, convenient and practical. 1. Through the real-time voltage value of throttle grip, you can accurately determine how much electric quantity is left, which is convenient for riding. 2. The real-time voltage value of throttle grip can accurately determine whether the lithium battery is damaged. 3. You can judge the quality of the lithium battery by the throttle grip voltage value, which is convenient for purchasing qualified lithium batteries. 4. Automatic identification of electric scooters with voltage below 100V can be used universally. 5. The ordinary electric display grip grip has 4 wires, which is convenient for installation and saves time. 6. Digital grip throttle grip. 2. Matters needing attention For non-professionals, please pay attention to the line sequence, and do not connect the wrong line, otherwise it will easily cause the burn for Hall and LED Third, the basic parameters: (according to different battery materials, different old and new, different batches, the voltage v number will be different, please test a few times, you can get your own electric scooter battery parameters,) 12V electric scooter, the highest voltage is about 12.6V or slightly higher, the lowest is about 9V or slightly higher 24V electric scooter, the highest voltage is about 29.4V, the lowest is about 21V or a little higher 36V electric scooter, the highest voltage is about 42V, the lowest is about 29V or a little higher 48V electric scooter, the highest voltage is about 54.6V or 58.8V, the lowest is about 39V or a little higher 60V electric scooter, the highest voltage is about 72V, the lowest is about 49V or a little higher 72V electric scooter, the highest voltage is about 84V or a little higher, the lowest is about 60V Higher voltage electric scooters are already equipped with voltmeters. Installation method: three throttle grip wires, red throttle grip positive pole, black throttle grip negative pole, green throttle grip signal line, yellow alone is the power cord positive pole.. Package List: 1 x Electric Scooters Throttle Grip 2 x Key Note: The default line length is 0.4m/1.3ft, and the digital display is 12V to 84V universal.
