Feature:1. No matter Lead-acid batteries, lithium batteries, water batteries, dry batteries.2. All kinds of electric vehicle (12V to 99V) can be automatically identified and displayed in real time.3. Through the voltage number to determine the fault of electric vehicle, twice the result with half the effort.4. By turning the real-time voltage value can accurately determine the amount of remaining power, convenient for you to drive5. The real-time voltage value can accurately judge whether the lithium battery is damaged.Specification:Condition: 100% Brand NewItem Type: E-Bike Thumb ThrottleMaterial: plasticColor: as picture shownModel: S series (5V-99V automatic identification of electric vehicle voltage)Efficiency: ≥98%Hall grade: linear hall, high quality rubber, imported LED digital display lampWorking voltage: turn DC0.8V-4.2VPower display: regardless of lead-acid battery, lithium battery, regardless of voltage, can be automatically identified (12V, 24V,36V,48V,60V,72V electric vehicles can be directly used, some 84V electric vehicles can be used)Quantity: 1 pairSpecification: electric vehicle universal accessoriesTerminal length: 2 m by defaultGreen is for throttle hall signal, red wire is for throttle +5v, black is negative wire; please connect according to controller function wire, U can not just match same color wire, if wrong connected that will damage your controller and throttle.4 wires : yellow is for voltage display wire, connect with electric bike power positive.5 wires: blue wire connect with controller power lock output wire, yellow wire connected with controller electric switch input wire power positive,6 wires: yellow connected with power positi
