For anyone travelling with their BlueROV2, you will need to plan ahead and send your lithium-ion batteries in advance to your final destination.
Within Australia, Li-ion and LiPo batteries are considered Dangerous Goods and will almost always travel by ground. For details on how to ship, see LiPo battery guidelines at Australia Post and their latest Dangerous Goods Packing Guide. You will most likely need to partially discharge the batteries before they are shipped in order to meet AusPost’s limit of 100 Watt-hour per battery, in addition to completing a Dangerous Goods declaration.
For international travel, you will be subject to IATA – Lithium Battery Guidelines and your chosen logistics company’s rules. Most international logistics companies have lithium battery guidelines published on their websites. For example, FedEx has a Lithium Battery Wizard to help you navigate their requirements.
Most shipping regulations are based on the IATA Dangerous Goods Regulations (DGR) for lithium batteries which was most recently updated in 2017. The IATA website also offers an updated Guidance Document for help on compliance with 2017 definitions, classification, exceptions, and prohibitions.
