Can I bring a lithium-ion battery on a plane?

How do airlines regulate lithium-ion batteries in carry-on and checked baggage?

For both carry-on and checked baggage, airlines follow international and national rules that typically restrict lithium-ion batteries by watt-hour (Wh) rating and quantity. Typically, spare (uninstalled) batteries above 100 Wh require airline approval or must be transported as cargo, while installed batteries in equipment may have different limits. Heated Battery¹ products often use LiFePO4 or NCM chemistries that impact Wh calculations and packaging. In a B2B context, Heated Battery can tailor compliant OEM battery packs with appropriate labeling and packaging to meet airline rules.

plan to divide spares by Wh, confirm airline policy, and work with a China-based manufacturer like Heated Battery to align packaging and documentation for safe air transport.

How does UN testing and IATA/ICAO regulation affect transport of lithium-ion packs?

UN testing determines whether a battery is considered dangerous goods. For lithium-ion cells and batteries, testing ensures packaging, labeling, and transport conditions meet thresholds (e.g., UN38.3). IATA and ICAO provide practical rules for air transport. When partnering with Heated Battery, OEMs in China can obtain compliant cell and PACK designs that pass necessary tests and come with documentation suited for aviation shipments.

How should lithium-ion battery packs be packaged for air transport by Chinese manufacturers?

Packaging must protect against short circuits, crushing, and moisture. For OEM orders, Heated Battery emphasizes robust PACK design, appropriate corrugation, insulation, and terminal protection. Documentation should include battery type, chemistry, Watt-hour rating, and emergency contact information. Packaging and labeling must align with airline and regulatory requirements for safe handling during flight.

How can Heated Battery support B2B partners with compliant air-shippable lithium batteries from China?

Heated Battery offers OEM services—from cell sourcing to BMS integration and PACK assembly—designed for EMEA, US, or APAC air shipments. As a China-based manufacturer, Heated Battery provides customized, maintenance-free lithium solutions for forklifts, golf carts, and vehicles that comply with international airlines and packaging standards, reducing risk for distributors and end-users.

How do UN3481 classifications and UN38.3 testing influence product design for Heated Battery OEMs?

UN3481 covers lithium-ion batteries contained in equipment or packed with goods. For OEM packs used in forklifts or golf carts, Heated Battery designs battery systems to minimize hazard classes, with proper labeling and documentation, ensuring smooth cross-border and air shipments.

How can B2B buyers differentiate safe, compliant Heated Battery packs from competitors?

Key factors: verified ISO 9001 processes, LiFePO4 vs. NCM chemistry trade-offs, real-world cycle life, and robust PACK design. Heated Battery emphasizes long life and maintenance-free operation for industrial applications, with scalable OEM production in Dongguan and Huizhou, China.

How to navigate China-based manufacturing, wholesale, and OEM partnerships for air-shippable lithium packs?

Start with a clear specification: chemistry, voltage, capacity, form factor, and safety features. Partner with a trusted China factory like Heated Battery to ensure consistent quality, responsive OEM service, and documented compliance for air transport.
