IATA DGR

Spare lithium-ion batteries ≤ 100 Wh may be carried in the cabin. Not in checked baggage as loose spares. Terminals protected against short circuit.

ICAO TI

Same 100 Wh passenger threshold as IATA. Operator approval is not required for cells/packs at or below 100 Wh.

UN 38.3 (cells)

P45B cells are UN 38.3 and IEC 62133 qualified by E-One Moli Energy. This card is the pack energy declaration for screening — not a cargo DG shipper's declaration.

CASA / TSA

Aligns with CASA and TSA passenger rules: lithium-ion spare batteries in carry-on only, under 100 Wh, protected from short circuit.

This article is a rechargeable lithium-ion pack assembled from six Molicel P45B 21700 cells. Rated energy is 97.2 watt-hours. It is not a lithium-metal battery. It is not over 100 Wh. It is not over 160 Wh. Cargo air freight of standalone batteries remains IATA PI 965 (typically ≤ 30% SOC) and is a separate process from passenger cabin carriage.

QuestionAnswer
What is it?One spare / removable lithium-ion drone battery pack
CellsSix Molicel P45B 21700 cells, 4500 mAh each, wired 6S1P
Watt-hours97.2 Wh (21.6 V × 4.50 Ah)
Over 100 Wh?No
Operator approval needed?No for ≤ 100 Wh passenger carriage
Checked bag as a loose spare?No — cabin / carry-on only
Installed on the aircraft?No. This is passenger baggage, not aircraft equipment
Lithium metal?No — lithium-ion only

Protect the terminals (installed on the rail, or taped / in a pouch). Do not carry damaged or swollen packs. For multiple packs, each pack is 97.2 Wh — still under 100 Wh each.
