Product Description

ebike thumb throttle with display

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 ( new or old, ),controller data , the battery voltage reaction will be different, so the data bellow will have deviation. Customers please check according to your battery to get your battery data.

For 12v electric bike, max voltage is about 12.6v, mini is about 9v or higher, For 24 electric bike, max voltage is about 29.4v, mini is about 21v or higher, For 36v electric bike, max voltage is about 42v, mini is about 29v or higher, For 48v electric bike, max voltage is about 54.6v, /58.8v, mini is about 40v or higher, For 60v electric bike, max voltage is about 72v, mini is about 49v or higher, For 72v electric bike, max voltage is about 84v, mini is about 60v or higher, For other electric bike with higher voltage there should be a voltmeter installed.

Speed Control Thumb Throttle for Scooter Electric Bike

The throttle with automatically identify voltage Replacement of analog battery level indicators Efficiency: ≥98% Hall Grade: Linear Hall, high-quality rubber, LED digital display light Operating Voltage: DC0.8V-4.2V Wire Terminal Length: 1.8 meters / 5ft How to maintain the lithium battery:

Since lithium battery has different materials (The ternary lithium battery, lithium manganate battery, lithium iron phosphate 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 max voltage number. Usually please charge 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 charge anytime, use anytime, that will not influence the life of battery. Please donot overcharge or overdischarge. Please totally charge and discharge for every two month, that will maintain the battery at max.

Ebike Thumb Throttle Battery Voltage Power Switch Wiring indication

Green 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.

5 wires: blue wire connect with controller power lock output wire, yellow wire connected with controller electric switch input wire power positive.

Battery Knowledge:

This digital battery voltage power switch directly obtains the battery power through digital voltage display. You can determine the remaining battery power based on your electric vehicle’s battery voltage (V), as well as check if the battery is damaged or depleted by examining the fully charged voltage. With this information, you can detect and repair any issues promptly.

Advantages of E-Bike Thumb Throttle Finger:

1. Compatibility with various types of batteries: They can be used with lead-acid batteries, lithium batteries, water batteries, and dry batteries.

2. Compatibility with various models of electric vehicles: They can be automatically recognized and display real-time information regardless of the voltage range (from 12V to 72V, and sometimes even compatible with 84V electric vehicles).

3. Replacement of analog battery level indicators: Instead of relying on a few small indicator lights, they provide real-time digital voltage display, which is more intuitive, convenient, and accurate for determining the remaining battery level and driving range.

4. Convenient diagnosis of electric vehicle faults: By monitoring the voltage, they can help diagnose and troubleshoot electric vehicle issues efficiently.
