Ooze Quad Flex 2 (Quad 2) 500mAh Square 510 Battery The Ooze Quad Flex 2, also known as the Ooze Quad 2, is a smart 500mAh square 510 battery built for everyday carts. It charges fast, hits smooth, and stays put on the table. This is a simple upgrade that fixes the annoying stuff cheap pen batteries get wrong. Why you want this battery Fast USB-C charging. Go from dead to full in about 20 minutes with a Type-C cable. No long waits. Use while it charges. Pass-through charging lets you keep using the battery while it’s plugged into the USB-C port. Square, no-roll body. Flat sides keep it from rolling off the table and snapping a cart. Set it down with less worry. Bright LED screen. See battery percentage, voltage setting, and connection status at a glance. No guessing why it won’t hit. Flex Temp voltage range. Five gentle voltage levels from 2.0V–4.0V help protect delicate coils and keep flavor clean. Dual charging options. Use the included Ooze Smart USB charger on top, or plug in USB-C on the bottom for True Fast Charge. Auto shutoff. After about 10 minutes of no use, the Quad Flex 2 turns itself off to save battery. How it feels to use Click it on. Set your voltage. Take a smooth pull. At lower settings, the Quad Flex 2 is gentle on 510 carts and doesn’t scorch the coil. At higher settings, it has enough power for thicker hits without pushing past 4.0V. You can see your battery level and voltage on the LED screen, so you always know what’s going on with your device. The square body and tech-grip texture make it easy to hold and hard to knock over. When you do set it down, it stays in place instead of rolling away. That small detail helps protect your cartridges and keeps your setup looking clean.
