EASA subject
Batteries and Electrical Systems
LiPo, charging, storage
Improper battery care is a common cause of fires and accidents.
Key concepts
- LiPo safety
- Never charge unattended, use a fire-safe bag, and avoid physical damage.
- Temperature
- Cold reduces capacity; heat increases fire risk and degradation.
- Storage
- Storage voltage ~3.8 V/cell; do not store fully charged long term.
Common mistakes
- Fully discharging the battery
- Charging on a flammable surface
- Continuing to use a damaged battery
Exam traps
- Full-charge voltage
- Cycle count
- Fire risk
Real-world example
A dented battery is charged — heat, swelling, and fire risk follow.
