Precautions

Never expose Batteries to extreme temperatures or direct sunlight.
Do not store Li-Po batteries in extreme temperatures below 0°C or above 50°C.
Always disconnect Batteries when not in use and store batteries in a non-conductive and fireproof container.
Never charge a battery that is still warm after usage, and never use a battery that is still warm from charging.
Actual safe discharge current depends on protection circuitry and thermal conditions. Exceeding rated values may reduce battery life or cause damage.
