The Ooze Novex 2 is a compact 510 vape battery with a digital screen and battery indicator. This super compact 400 mAh vape battery conceals your 510 cart and features a new colorful digital screen that tells you exactly what's going on with your pen.
The Novex 2 starts at 2.0V and can heat up to 4.0V. We've found over the years that lower voltages are ideal for 510 cartridges. Most carts can't handle super high heat continuously, and it's easy to burn the coil on the bottom.
