Because LiPo batteries contain lithium, they can pose a fire risk if stored incorrectly. It is therefore important to store them in a cool, dry, and dark environment away from direct sunlight and heat sources.
For additional safety, special LiPo Safe bags are available for storage and transport.
If you are not using a LiPo battery for an extended period, it is recommended to store it at approximately 60% charge (storage voltage). Many modern LiPo chargers include a dedicated storage mode for this purpose.
