Please note before purchase:

1. What is the voltage of your bicycle? If it's 36V, buy a 36V battery. If it's 48V, buy a 48V battery. You can also tell the voltage of the battery
you need from your original battery or the control center. 10Ah,15Ah,20Ah, and 30Ah represent the battery capacity and indicate the range

2. Is the size of the battery suitable for fitting into your bicycle frame

3. The interface between the battery and the base needs to be determined. We have two types of interfaces: 4-pin and 5-pin. If your original
battery base is 4-pin and you don't want to replace the base, you can purchase a 4-pin battery set. If it's a 5-pin battery base, buy a 5-pin
battery because our battery set includes the base.

Of course, if you don't mind replacing the original battery base, you don't need to worry about whether the battery base is 4-pin or 5-pin,
because our batteries come with battery bases

4. When charging, please connect the power supply first and then the battery

5. Do not use up all the battery power completely. The battery should be charged each time with some remaining power

6. When you receive a new battery, make sure to charge it before using it.
