1. RealTime Voltage Monitoring and Battery Protection: This advanced ebike thumb throttle features a bright LCD display that shows realtime voltage (12V99V autorecognition), allowing you to accurately monitor battery levels for leadacid, lithium, dry, and water batteries. Prevents overcharging and damage. 2. Universal Compatibility and AutoVoltage Detection: Works seamlessly with all electric vehicle types (12V99V), including ebikes, escooters, and emotorcycles. The smart system automatically identifies battery voltage without manual adjustments— for lithiumion, ternary lithium, and LiFePO4 batteries. Includes wiring for 3speed/5speed modes, reverse gear, cruise control, and power lock functions. 3. Efficiency Throttle Control and 3Speed Modes: Equipped with a precise linear Hall sensor and 98% efficiency, this thumb throttle delivers smooth acceleration and responsive speed control. Choose between 5wire (basic) or 7wire (multifunction) versions for /medium/low gears, horn, cruise, or reverse functions—compatible with your ebike controller. 4. Waterproof Design for AllWeather Use: Built with impactresistant ABS plastic and sealed connectors, this waterproof ebike throttle withstands rain, dust, and vibrations. The 1.8meter extended wires (colorcoded: red/black/green/yellow) enable flexible installation on MTBs, road bikes, and fattire ebikes.
