but I'll spend out the ass to hack together battery packs from 18650 cells and trays. Four trays fit, each with four cells in series, 3.7Vdc each.
the hard part is getting the connectors that mate to the radio. I might just bind all four trays in parallel and wire them out through the charging access and over to the external DC molex. I have those parts already.
There were also a few sets that didn't get marked with anything when I got them, because I didn't realize how quickly the camo pattern faded. Sainted Wife got into the act, when I noticed one set with a red square Sharpied on the labels because she couldn't find any month and year.
So the next uniforms I received, 3 sets of ripstops, arrived just as a muharib shot up a nightclub in Orlando. Three sets at once, that needed to stay together as sets.
I labeled one set "Orlando." Then another set "Garland" and the third "Ft Hood."
With our new normal of Islamic atrocities on US soil, I will be renaming the other uniforms.
Update: today a uniform has been marked OHIO STATE.
I refer, of course, to AFI 1-1, paragraph 1.6.5, forms of address for all Air Force ranks, and the habit of Enlisted folk addressing one another as "sir." It's not there; the AFI does not permit nor require it. Yet Airmen literally of all stripes continue to do it; I've been addressed hundreds of times at this location as "sir" but thank the ghost of Hap Arnold I haven't been called out for not addressing others that way myself.
Among the enlisted, Chiefs may be addressed in the short form as "Chief." All other NCO ranks may be addressed in the short form as "Sergeant." That's what I do, though usually with the Army-approved "Sar'nt."
Yet as an E-8, I am also addressed regularly by officers as "Senior." The AFI does not sanction that either.
