Check my post Transceivers, checked or carry on baggage?
From a dangerous goods perspective, the radio transmitting equipment would be classed as consumer electronics when carried by passengers for personal use. If the lithium ion batteries do not exceed 100Wh, these can be carried in checked or carry-on luggage. Spare batteries can only be in carry-on baggage and you can take a maximum of 2 spares for each item.
The 30% state of charge is only for shipping as cargo. I’ve never had any issues, with batteries anyway ;), just had them swabbed for ‘explosives’ or whatever, once the x-rays have shown up something security don’t immediately recognise.
