1 Pair EBike Thumb Throttle, Electric Scooter Grip Throttle LCD Display Digital Battery Voltage Power Switch for Electric Vehicle Electric Modification Accessories Real-time digital voltage display - By turning the real-time voltage value can accurately determine the amount of remaining power, convenient for customers to drive.Eliminate analog power display (a few small lights), real-time digital voltage display, intuitive, convenient, can accurately judge the remaining power, mileage. How to maintain the lithium battery - No matter - batteries, lithium batteries, water batteries, dry batteries.Since lithium battery has different materials (The ternary lithium battery, lithium manganate battery, lithium iron battery) so we cannot give exact number to measure the balance battery level. Customers please measure the remaining battery level according to your battery indication and voltage number. Monitor battery - The real-time voltage value can accurately judge whether the lithium battery is damaged. All kinds of electric vehicle (12V to 99V) can be automatically identified and displayed in real time.The quality of lithium battery can be judged by the value of turning voltage to facilitate the factory to purchase qualified lithium battery. Specification: Model: S series (5V-99V automatic identification of electric vehicle voltage) Efficiency: ≥98% Hall grade: linear hall, high quality rubber, imported LED digital display lamp Working voltage: turn DC0.8V-4.2V Power display: regardless of - 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 pair Specification: electric vehicle universal accessories Terminal length: 2 m by default For 12v electric , maximum voltage is about 12.6v, mini is about 9v or higher, For 24 electric , maximum voltage is about 29.4v, mini is about 21v or higher, For 36v electric , maximum voltage is about 42v, mini is about 29v or higher, For 48v electric , maximum voltage is about 54.6v, /58.8v, mini is about 40v or higher, For 60v electric , maximum voltage is about 72v, mini is about 49v or higher, For 72v electric , maximum voltage is about 84v, mini is about 60v or higher, For other electric with higher voltage there should be a voltmeter installed. Installation method: 3 wires, red wire for positive, black wire for negative, green wire for , and yellow wire for power supply positive. Package List: 2 x Keys 2 x Accessories
