Specification: Condition: 100% brand newItem type:ElectricScootersThrottleGripMaterial: plasticColor: blackWeight: Approx. 182gModel: S series (5V-99V automatically recognizes the voltage of electric scooter) Efficiency: Y98% Hall grade: linear for Hall, high quality rubber, imported LED digital display light Working voltage: ThrottleGrip DC0.8V-4.2V Power display: regardless of lead-acid battery,lithiumbattery, 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 scooterbattery voltage V number. You can also determine whether the battery is damaged and slightly damaged by the fullcharged 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 lightfrom 31V to 34V is on. This method can be blurred, because it is impossible to determine electric quantity.
