Description
Meet the QM Weels V20 Battery, a high-quality 48-volt battery with a capacity of 15 amp-hours. This battery is known for its impressive capacity and reliable performance. With a powerful 15 Ah power supply, the QM Weels V20 Battery provides enough power to effortlessly tackle hills and cover longer distances, while benefiting from smooth and efficient electric assistance.
The battery can be charged in two ways:
- In the bike: You can leave the battery in the bike and connect the bike to the charger. When you then check the display, it will show how fully charged the battery is.
- Outside the bike: You can remove the battery from the bike. You can then, for example, charge the battery indoors. There is a small button on the battery that indicates how fully charged it is.
We recommend not placing the battery adapter on the saddle while charging. It may become hot.
Connection: The V20 battery uses a 5-pin connection. Before ordering, check whether your bike also has a 5-pin connection; a 4-pin battery or holder will not fit.

Buy V20 battery at GoFatbike
The battery of the V20 is a 48-volt pack with 15 amps and provides power for your pedal assistance. If your range decreases or the battery no longer holds a charge, replacing it is usually enough to get the bike running normally again. You can charge it in two ways: while in the bike, where the display shows how full it is, or separately from the bike, for example indoors at a power outlet.
When ordering, make sure the voltage matches your current battery and charger, as a 48-volt system does not work with a charger from a different pack. Also, check the mounting on your frame and the lock, as these can vary by model year. The exact details are listed in the specifications on the product page so you can compare before ordering.
