Proper charging is essential to maintaining the security and longevity of LiPo batteries. Listed below are some suggestions for secure charging:
- Use a Balancing Charger: Balancing chargers help make sure that each cell inside the battery pack is charged evenly, stopping overcharging of individual cells and reducing the chance of fireside or swelling.
- Monitor the Charging Process: Control the charging process, especially during hot weather, to stop overheating. Think about using chargers with built-in safety features like temperature control.
- Store Appropriately
Proper storage is important when not using LiPo batteries for an prolonged period. Follow these guidelines for storing LiPo batteries:
- Maintain the Right Voltage: The really helpful storage voltage for LiPo batteries is around 3.8 volts per cell. Storing them at this voltage helps prevent overdischarge or overcharging during long periods of inactivity.
- Select a Secure Location: Store LiPo batteries in a cool, dry place away from flammable materials. Avoid keeping them near sources of warmth or direct sunlight. Some professionals use bags specifically designed for storing/charging LiPo batteries.
By following these best practices for handling, charging, and storage, we will enhance the security and performance of LiPo batteries while extending their lifespan.
Best Practices for Using LiPo Batteries in UAS During Hot Weather Conditions
When using LiPo batteries in Unmanned Aircraft Systems (UAS) during hot weather conditions, it’s necessary to follow specific safety guidelines to cut back risks and make sure the secure operation of LiPo-powered tools. Listed below are some best practices to contemplate:
- Monitor battery temperature. High temperatures can harm LiPo batteries, so it’s crucial to observe their temperature during flight. Many modern drones have built-in sensors that provide real-time temperature data. By keeping track of battery temperature, we will take appropriate motion if it starts to rise too high.
- Implement thermal protection mechanisms. To further protect LiPo batteries during hot weather conditions, take into consideration using thermal protection mechanisms. Some drones have features like automatic cooling systems or thermal insulation for the battery compartment. These measures can assist control the temperature and forestall overheating.
- Avoid direct sunlight exposure. Direct sunlight can quickly raise the temperature of LiPo batteries. Every time possible, keep UAS/drone and batteries away from direct sunlight, especially when not in use. This straightforward precaution can assist prevent excessive heat buildup and extend the lifespan of LiPo batteries.
- Allow cooling periods between flights. When planning multiple flights in hot weather, make sure that to permit enough time for cooling between each flight. Letting the LiPo batteries cool down before charging or using them again will help maintain their performance and forestall potential damage from overheating. NEVER charge a hot battery. It could not necessarily puff or self-ignite; the interior damage is irrecoverable and causes premature lack of energy, shortening the useful lifetime of the battery.
- Store batteries in a cool environment. When not in use, store LiPo batteries in a cool dry location to attenuate heat exposure. Keep batteries from direct sunlight and avoid storing them in a hot automotive or every other location that may turn into excessively warm.
The LiDARPROs team use cooler bags designed for warm weather. Don’t use ice nor “blue blocks” that might make direct contact with any battery surface. Our bags have thick terry towels separating the batteries from the cooling plate. Place batteries right into a cooling bag until it’s time to make use of them. Don’t put a hot battery/just-used battery right into a cooling bag. Let the battery cool down prior to storing within the bag. Set the cooler bag to its “warmest” setting. Cooler bags usually are not freezers, and customarily don’t dip below 70 degrees (in our experiences). Most of those products offer “15 to twenty degrees lower than ambient temperature.” We do keep a small, relatively accurate thermometer within the bag in the course of the hot months. A few of these products also offer warming capability, for those in very cold winter environments.
TIP: Our team lays batteries out with their “belly down” to point the battery is charged and prepared for operations. A battery placed on its back indicates a “belly up” battery, which has been expended. We also divide them within the storage containers in the identical manner.
By following these best practices, pilots can significantly reduce the risks of using LiPo batteries in hot weather conditions:
- Monitor battery temperature
- Implement thermal protection mechanisms
- Avoid direct sunlight exposure
- Allow cooling periods between flights
- Store batteries in a cool environment
These steps are essential for ensuring the secure and optimal performance of the aircraft. Remember, safety should at all times be a top priority when using LiPo batteries in UAS. Taking these precautions is not going to only protect expensive equipment but additionally contribute to the longevity of batteries and overall flight experience.
Do Not Store Batteries within the UAS
Storing batteries installed within the UAS could be very tempting. Nonetheless, should a battery begin to puff, it may “lock” itself into the battery housing of the aircraft, potentially damaging internal components of the UAS. We’ve seen no less than one UAS platform destroyed through storing a battery within the battery compartment of the UAS>
Summary
It can be crucial to recollect the risks of leaving LiPo batteries in hot cars and the importance of responsible battery management. By following proper safety guidelines, we will prevent accidents and make sure the longevity of our batteries, stopping errors, disappointments, and failed flights.
