E Bike Voltage Display & 2 Keys, thumb throttle Digital Battery Switch Power with Key Lockebike

【Convenient to Use】By turning the real-time voltage value can accurately determine the amount of remaining power, convenient for you to drive. Usually please when there is 30% left, and please finish charging when reach to 80% of battery. This is best for battery. Any lithium battery has no memory, you can anytime, use anytime, that will not influence the life of battery. 【Battery Common Sense】For this display Battery is measured by voltage. this throttle can work for any electric bike under 84v with lead acid battery, lithium battery, water battery, dry batter and so on. The throttle with automatically identify voltage. Due to the difference of battery material, battery conditions, controller data , the battery voltage reaction will be different. 【Real-time Voltage Value】The real-time voltage value can accurately judge whether the lithium battery is damaged. Through the voltage number to determine the fault of electric vehicle, twice the result with half the effort. 【Power Display】All kinds of electric vehicle (12V to 99V) can be automatically identified and displayed in real time. 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. 【Lithium batteries】No matter Lead-acid batteries, lithium batteries, water batteries, dry batteries. The quality of lithium battery can be judged by the value of turning voltage to facilitate the factory to purchase qualified lithium battery. Please totally and discharge for every two month, that will maintain the battery at maximum. Please donot overcharge or overdischarge.
