    FAQ

    Will Ebike Battery Bag，40L Hard Shell Waterproof Electric Bicycle Rear Rack Bag with Reflective Strips and Shoulder Straps，bike rack bags for ebikes，E-Bike Accessories. work with my e-bike?

    It may work if your e-bike matches the product voltage, controller current, connector type, polarity, and mounting dimensions. Always verify these details before buying or installing.

    How far can Ebike Battery Bag，40L Hard Shell Waterproof Electric Bicycle Rear Rack Bag with Reflective Strips and Shoulder Straps，bike rack bags for ebikes，E-Bike Accessories. go on one charge?

    Range depends on the battery energy, rider weight, terrain, speed, assist level, wind, tire pressure, and battery age. Check voltage and capacity first, then estimate watt-hours.

    What motor power is this product suitable for?

    Check the listed motor support and controller current requirements. Motor wattage alone is not enough to confirm compatibility.

    What BMS rating should I check?

    Compare the battery BMS amp rating with your controller's maximum current draw. Avoid using a pack that is underrated for your setup.
