Unit Pack Power Battery – Safety Guidelines

Lithium-Ion Battery Safety Guidelines


ALWAYS follow the manufacturer’s instructions for charging and storage. Only use the original manufacturer’s battery, cord, and power equipment to charge the lithium-ion battery. Only use the battery specifically designed for your bike.

ALWAYS charge the lithium-ion battery at room temperature. If the battery is still warm from usage, allow time for the battery to cool before charging. DO NOT charge the lithium-ion battery at temperatures below 32°F (0°C) or above 105°F (40°C).

ALWAYS store your lithium-ion battery in a well-ventilated area that has a fire detection system. Avoid any sun exposure, water (especially salt water), humidity, and/or condensation. Keep the lithium-ion battery away from any heat source or any flammable materials, such as paper, under or on a pillow, bed, or couch. DO NOT place the battery in or near fire, stoves, microwaves, or other heating devices.

NEVER attempt to modify or service your bike battery system. Batteries are part of a larger system within the e-bike. It’s not just the battery but also the sensors, motor, controller, and other components. Altering a component within the system can impact the safety of the system, which can result in property damage, severe injury or death.

ALWAYS plug the lithium-ion battery charger directly into a wall outlet. NEVER use power strips or extension cords to charge your lithium-ion batteries. DO NOT stack or cluster the lithium-ion batteries together while charging or storing. Charging multiple batteries with inadequate electrical support is a major safety hazard.


ALWAYS monitor the battery and charger when charging; NEVER leave it unattended or overnight. Do not keep charging the lithium-ion battery after it is fully charged. DO NOT store the battery at 30% of charge or below. The ideal state of charge for short and long term storage is 60%.

DO NOT use the battery or charger if your battery has been opened, damaged, punctured, burned, been smoking, or has been on fire. Inspect the battery and charger before and after each use.

NEVER use a battery if it shows signs of physical or mechanical damage such as a change of shape, discoloration of the battery’s shell, leaking, odor, a sign of corrosion, odd noises, loose or damaged wires/connectors, or known misuse.


NEVER place a lithium-ion battery in the trash or in a recycling bin; it is illegal. DO NOT put discarded batteries into piles. To properly dispose of lithium-ion batteries, take them to a battery recycling location or contact your local waste management service provider for disposal instructions.

INHERENT RISK OF LITHIUM-ION BATTERIES

  • Lithium-Ion batteries (and other rechargeable batteries) are potentially dangerous. Lithium Ion batteries, especially when subjected to abusive conditions, may become hot, explode, and/or ignite and can cause serious injury to person or damage property. Unit Pack Power holds no responsibility for any injury or damage caused by the use of any Lithium-Ion batteries (or other rechargeable batteries). You, the purchaser and/or user of any Lithium-Ion Battery or product containing Lithium-Ion Batteries are responsible for the use of such products.
  • Never modify a lithium battery. Modifying an electric bike battery pack is highly discouraged because it can compromise the internal integrity of the pack. Such alterations can lead to unpredictable battery behavior, increasing the risk of fires due to thermal runaway. Our battery pack technology is the result of years of development with the goal of making them as safe as possible and compliant with regulatory bodies, any modification will make the pack simply unsafe. Tampering with the battery will void the manufacturer’s warranty, and releases Unit Pack Power from any liability in case of an incident.
  • Only use the battery brand and model specifically designed for your bike.
  • When using a Lithium-Ion battery, never connect the positive and negative terminals of the battery to each other with any conductive material (also known as a “short” or “shorting” the battery).
  • Keeping your battery in a safe location can help reduce, but not necessarily eliminate, the risks associated with using a Lithium-Ion battery. Never expose your battery to water (especially salt water), allow the battery to get wet, nor store the battery in any location where it may come into contact with water. Always keep your battery in a cool location, and out of direct sunlight. The inside of cars can regularly be tens of degrees higher than the outside temperature, especially during summer and when the car is in direct sunlight. Do not place the battery in or near fire, stoves, microwaves, or other heating devices.
  • Always turn your battery off when not in use. Never charge your battery when unattended. Never allow the battery to become overcharged. Even with the use of recommended smart chargers, damaged or malfunctioning batteries can still become overcharged and become hot, ignite, or explode. Due to this risk, never charge your battery unattended. Immediately discontinue use if at any time the battery emits an odor, feels hot, changes shape or color, or appears abnormal in any way. Never use water to cool down an overheated battery. Never compress, put excessive pressure on, or puncture your battery. 
  • Only use the charger that came with your battery pack and was designed for your pack.
