this battery does 100 percent fit on the macfox x1 and x1s

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 fit 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. It is better for the battery to charge it each time with some remaining power

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

Select the corresponding option. Clicking on the option will bring up the corresponding option's image, which includes battery parameters such as the battery's
size and the number of pins.
