510-thread cart batteries and dab pens
A 510-thread battery works with any standard cartridge, and the difference between a good one and a cheap one is voltage control and build quality. Heavy Heads carries Ooze Slim Twist and Booster, Pulsar 510 DL and APX, and no-nonsense 350mAh variable-voltage pens with charger kits.
Variable voltage matters: run a cartridge at 2.4–2.8V for flavor, 3.2–3.6V for bigger hits, and use preheat to loosen thick oil in cold weather. A 510 battery needs no coils or refills — just charge it and screw on a cartridge.
Chargers are included where the listing says so. Ships from Minnesota. 21+ only.
