The voltage (V) of the battery is the same as that of the motor.When purchasing an ebike Battery Pack, always ensure that voltages are paired correctly (eg. a 36V motor must be paired with a 36V battery). The maximum power (Watt) and maximum current (Amp) of the battery must be greater than or equal to the power and current of the motor. (for example: 36V 500W 20Amp battery pack can be used for 36V 350W 15Amp motors, on the contrary 36V 350W 15Amp Battery cannot be used for 36V 500W 20Amp motor).”‘AH’โ€™does not affect the matching of the battery and the motor. It only determines the mileage of the electric bicycle battery. The greater the WH, the longer the mileage.(WH=Voltโœ•AH)Please carfull browse the battery patameters before placing your order,make sure your bike frame have enough space to fit the battery, choose the battery that suits your requirement, avoid buying errors.Tip: If the battery discharge port is not compatible with your controller connector, you can cut off the plug of the controller and connect it with the adapter provided by us with adhesive tape.
