BC Flash (Battery-Capacitor Flash) was a flash photography system used with flashbulbs. Instead of relying directly on the current pulse ability of a battery to directly fire a flashbulb, a battery was used to charge a capacitor that would then discharge through the flashbulb. BC flash units used either 15V or 22½V batteries.
