Important Safety Information

Lithium-ion batteries may present a fire, electric-shock, or injury risk when damaged, incorrectly installed, improperly charged, short-circuited, modified, or used with incompatible equipment.

• Use only the charger supplied with the battery or an approved charger with the correct voltage and connector.

• Do not leave the battery charging unattended.

• Do not charge near flammable materials.

• Do not charge or use a swollen, leaking, overheated, wet, punctured, crushed, or damaged battery.

• Do not open, modify, disassemble, or short-circuit the battery.

• Keep the battery away from fire, excessive heat, water, and direct sunlight.

• Installation should be completed by a qualified electric-bike technician.

• Secure the battery firmly before riding.

• Follow the supplied instruction manual for charging, installation, operation, and storage.

• Store the battery in a cool, dry, ventilated location away from children and flammable materials.

• Check your local authority’s requirements for lithium-ion battery recycling and disposal. Never place the battery in household waste.

Battery performance, range, cycle life, and usable capacity depend on rider weight, terrain, speed, temperature, tire pressure, controller settings, motor power, and charging practices.
