Frequently Asked Questions
What is the optimal storage voltage for high-rate drone LiPo batteries?
For long-term storage exceeding 48 hours, store LiPo cells at 3.80V to 3.85V per cell (approximately 50% State of Charge) in a temperature-controlled environment between 15°C and 25°C. Storing at full charge (4.20V/cell) accelerates electrolyte decomposition and internal resistance growth.
How does operating temperature affect high C-rate continuous discharge?
Cold ambient temperatures (below 10°C) increase internal resistance and cause pronounced initial voltage sag under heavy throttle. Pre-heating battery packs to 25°C–35°C prior to flight ensures maximum burst power delivery and protects the anode from lithium plating.
What compliance certifications are mandatory for exporting commercial drone battery packs?
Air and maritime transport require certified UN38.3 test summaries, 1.2m drop test certification, and validated MSDS documentation. Commercial compliance in North America and Europe typically mandates CE (EMC/LVD), RoHS, and IEC 62133 safety verification.
