Does the handbook specify the type of battery required for the instruments, or
prohibit LiFe batteries? If not, and it's easily removable, I think you can
reasonably claim it's a portable device and use one of your choosing in the
glider; after all, you likely have Lithium batteries in it already - your cell
phone, your inReach/Spot, your logger, and a handheld radio.
