I try to have all my battery powered equipment use the same batteries. My flashlights are LEDs and all use AA batteries. The two way radio also uses AAs. The Red dot Im eventually putting on my AR15 uses AA. The two way radio can also receive emergency weather channels. The only other thing that uses different batteries are any weapon mounted lights. They are types that both use CR123s. More spares for the AR15 light car be kept in the fore grip.
Thats pretty much it give or take a couple things. Its kinda a work in progress.
