If at any time you witness a battery starting to balloon, swell up, smoke or become hot, discontinue the charging process immediately, disconnect the battery, and observe it in a safe place for approximately 15 minutes. This may cause the battery to leak, and the reaction with air may cause the chemicals to ignite, resulting in a fire.

Since delayed chemical reaction can occur, it is best to observe the battery as a safety precaution. Observation should occur in a safe area outside of any building or vehicle and away from any combustible material.

Wire lead shorts can cause fire! If you accidentally short the wires, the battery must be placed in a safe area for observation for approximately 15 minutes. Additionally, if a short occurs and contact is made with metal (such as rings on your hand), severe injuries may occur due to the conductibility of electric current.

A battery can still ignite even after 10 minutes.

In the event of any damage due to dropping the charger, you must remove the battery for observation and place it in a safe open area away from any combustible material for approximately 15 minutes.

Some LiPo/Li-ion chargers on the market may have technical deficiencies that may cause it to charge the LiPo/Li-ion batteries incorrectly or at an improper rate. It is your responsibility solely to assure the charger you purchased works properly. Always monitor the charging process to assure your batteries are being charged properly. Failure to do so may result in fire.

Always use a specific Lithium Polymer/Li-ion charger only. Do not use a NiMH or NiCd charger- Failure to do so may cause a fire, which may result in personal injury and property damage.

Also, never charge batteries unattended. When charging LiPo/Li-ion batteries you should always remain in constant observation to monitor the charging process and react to potential problems that may occur.

Do not use batteries that are damaged, peeling, punctured, dented, or cosmetically altered Always use a smart charger with protection circuits.

Lithium batteries have their own life cycle. Please replace old batteries with new ones when they reach their service life or when they are two years old, whichever comes first.

• Do not build your own battery pack or charger. Always use those specific to your battery and manufactured with a UL certification.  Do not modify a charger.
• Never make the wrong polarity connection when charging and discharging battery packs. Always double check the polarity of the battery connector to make sure red wire to red wire and black wire to black wire.
• Do not mix and use old batteries and new batteries, or batteries with different brand names.

When charging the Battery Pack, please put the battery in a fireproof container. Please don't leave the battery pack and charger on wood material or a carpet and unattended.
