Range is an estimate. Rider weight, terrain, speed, wind, tire pressure, assist level, and battery age can change the result.
It may work if your e-bike matches the product voltage (20V), controller current, connector type, polarity, and mounting dimensions. Always verify these details before buying or installing.
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.
Check the listed motor support and controller current requirements. Motor wattage alone is not enough to confirm compatibility.
Compare the battery BMS amp rating with your controller's maximum current draw. Avoid using a pack that is underrated for your setup.
Use only a charger that matches the battery chemistry, full-charge voltage, connector, and polarity. A mismatched charger can damage the battery or create a safety risk.
