What are the hazards of swollen lithium batteries

When using a swollen lithium battery, the following phenomenon is most likely to occur: instantaneous pressure drop. Because the battery test of many flight controllers currently relies on voltage, and the swollen lithium battery is very easy to lose pressure, it may be 50% of the battery in the last second, and the next second will prompt an emergency landing; the discharge rate is unstable, resulting in sudden power failure Big and small. Especially on a multi-rotor, it may cause uneven and irregular shaking of the aircraft; the stored power is very small. Due to the presence of air inside the swollen battery, it will affect its stored power, causing the battery to overflow quickly and quickly run out; there is a safety hazard. Due to the internal instability of the swollen lithium battery, it is easy to cause spontaneous combustion and other phenomena. If you have such batteries, the best policy is to discard them in time.
