Why Do LiPo Batteries Explode?

Incompatible batteries and chargers can result in unsafe conditions.

About

LiPo batteries are a popular battery for use in mobile devices and rc toys. Compared to nickel cadmium-based batteries, they are lighter and hold more energy.

Dangers

Lithium polymer batteries require specific charging equipment. If a battery is overcharged, charged using an incorrect voltage or reverse charged, it could result in a fire or explosion. A swelling of the battery pack shows signs of overcharging and impending explosion. These dangers pose a threat to not only the equipment containing the battery, but also any people nearby.

Safety Precautions

Only use charging equipment specific to the voltage requirements and battery type. Use of a different charger could result in overcharging and create a hazardous situation. Battery charging should be done in a suitable temperature and location to avoid risk of exposure to extreme conditions.
