LiPo (Lithium-Polymer) batteries are widely used in the fields of radio-controlled vehicles , drones, and other portable electronic devices. Although they offer many performance advantages , it is essential to handle, store and transport them carefully to avoid the risk of accidents. In this article, we outline best practices for safe storage and transportation of LiPo batteries.
LiPo battery storage
The ideal storage location for your LiPo batteries should be ventilated, cool, dry, and with a temperature between 5°C and 27°C. Batteries should be stored at half charge (approximately 3.8 volts per cell). On modern chargers , a “storage” function allows you to obtain the appropriate storage voltage.
It is important not to leave your LiPo batteries fully charged or discharged for a long period of time. Fully charged batteries may swell, while fully discharged batteries may become unusable if they drop below 3.2 volts per cell.
To store your batteries safely, it is recommended to use a fire-resistant charging bag , which can slow the spread of a possible fire.
Balancing and discharging LiPo batteries
While using your LiPo batteries, it is essential to monitor their discharge status. Battery monitors , such as those with an LED display, can help you monitor the voltage of each cell and detect possible imbalances.
Balancing a LiPo battery consists of harmonizing the voltage between the different cells. Devices such as battery testers or chargers with balancing function can be used to balance your batteries.
Transportation of LiPo batteries
When transporting your LiPo batteries , the ambient temperature must be between 5°C and 50°C and they must be protected from the sun. Use a fireproof charging bag to transport your batteries safely.
Secure storage and transport accessories
Protective bag
Protective bags specially designed for LiPo batteries provide an extra layer of security when storing and transporting your batteries. These bags are usually made of fire-resistant materials and can help contain a possible fire .
Ammo boxes
Steel ammo boxes provide excellent protection against fire . You can also place your batteries in a fireproof charging bag inside the ammo box for maximum protection.
By following these recommendations, you will be able to store and transport your LiPo batteries safely, while preserving their lifespan and minimizing the risk of accidents. Remember that safety is paramount when using LiPo batteries. It is also essential to be familiar with emergency procedures in the event of an incident, such as using a suitable fire extinguisher to put out a LiPo battery fire .
