Never travel with anything you cannot afford or are unwilling to lose. Note the value of what you pack and the insurance available to you if the item is lost.

Always check the types and limits on batteries of anything you check or carry on.

"Lithium batteries with 100 watt hours or less may be carried in a device in either carry-on or checked bags. Loose lithium batteries are prohibited in checked bags. For more information, see the FAA regulations on batteries."

Then consider the weight. Tools and Batteries = Heavy
