How many spare POC batteries can I bring on a plane?

For batteries under 100 Wh (which covers most Inogen and OxyGo single and double batteries), the FAA sets no numerical limit—but you must be able to physically carry them. Use the 150% rule based on your total transit time to determine the exact number you need.

Can POC batteries go in checked luggage?

No. All spare lithium-ion batteries must be in your carry-on baggage. Only the battery currently installed in the device may be in checked luggage (inside the device). This rule is non-negotiable under FAA Advisory Circular AC 120-76E.

Frequently Asked Questions

Q: Which DJI battery fits my drone?

A: DJI batteries are NOT interchangeable across series. Mini uses 2S (7.2-7.7V). Air uses 3S-4S (11.55-15.4V). Mavic uses 3S-4S (11.4-15.4V). Phantom uses 4S (15.2V). FPV uses 6S (22.2V). Always match the battery model to your drone. Mini 4 Pro and Mini 3 Pro share the same battery. Air 2 and Air 2S share the same battery.

Q: How should I store DJI drone batteries?

A: Store at 40-65% charge. Never leave fully charged for more than 3 days. Keep cool and dry. For storage over 1 month, check and top up to 40-65% every 3 months. Use a LiPo safety bag for fire protection.

Q: How many charge cycles does a DJI battery last?

A: DJI batteries are rated for 200-300 cycles before noticeable capacity loss. One cycle = cumulative discharge of 75% of rated capacity. At 200+ cycles, expect shorter flight times. Replace when runtime drops below 70% of original.

Q: Can I fly with DJI drone batteries?

A: Yes. All DJI consumer batteries are under 100Wh (Mavic 3 is 77Wh, Phantom 4 is 89.2Wh). FAA allows spare lithium batteries under 100Wh in carry-on. Never in checked luggage. Cover terminals. Check with your airline.

Q: Should I buy OEM or third-party DJI batteries?

A: Genuine DJI batteries include a BMS chip that communicates flight time and safety data to the drone. Third-party batteries often lack this chip — no flight-time readout, potential safety risks. For critical flights, OEM is recommended. For casual flying, quality compatibles save money.
