Battery-pack parasite droids were small droids shaped like battery packs for blaster rifles. They were used by Wraith Squadron in 44 ABY, who planted them on a number of Galactic Alliance Army blaster rifles during their investigation of General Stavin Thaal. They had a very limited amount of charge and also could move independently, as well as subvert other simple droids. The droids were equipped with sensors and burst-transmitters for surveillance.
