The Black Button Battery by Heavy Hitters is the ultimate variable voltage battery designed to enhance your vaping experience. Engineered specifically for Ultra and Live cartridges, this battery is built to preserve the flavorful terpenes and extend the life of your cartridge. Featuring an easy-to-use design, simply choose your ideal temperature with the button-activated feature. The battery offers three voltage settings: 2.0v, 2.5v, and 3.0v, allowing you to customize your vaping experience to your preference. For the best enjoyment of LIVE by Heavy Hitters, we recommend using the 2.0v setting (indicated by a blue light). For a fuller hit fused with flavor, try the 2.5v setting (green light). And for an ultra-heavy hit, select the 3.0v setting (red light). The Black Button Battery is compatible with all 510 thread cartridges and comes with a micro-USB cable for convenient charging. To power on the battery, simply click the square button five times rapidly, and the blue light will blink three times. Hold the button and inhale to enjoy your vape. To switch between voltage settings, click the button three times. Additionally, you can initiate a 10-second pre-heating cycle by clicking the button twice.
