Lithium battery purchase guide
1. What is the voltage?
It's not clear what the voltage is. Please check the output voltage on the back of the charger. It's also available on the controller. If the output is 42V, it's 36V. If the output is 54.6V, it's 48V!
2. What is the battery size?
After removing the battery, use a ruler to measure the length, width and height of the battery. If it is not convenient to remove the battery, you can also measure the length, width and height of the inner diameter of the battery compartment. If you need to buy the battery and install it in the original shell, you need to measure the length, width and height of the inner diameter of the shell, and inform our customer service!
3. What's the capacity?
Under the same voltage, ah is the capacity, not the current. The larger the capacity is, the farther it runs, there is no problem of burning the motor. Because the same voltage V, the same current a, the charger does not need to be replaced. If the size allows, you can choose a larger capacity!
4. About the battery plug?
Please take photos of the plug on your current battery and send it to customer service. Try to match it with the same plug. If the plug is not right or the line is not long enough, please cut off the wiring without affecting the use. Battery is live, please cut, wire and bind separately!
