510-thread batteries — what to buy
A good 510-thread battery is the most useful accessory you can own if you vape carts. Variable-voltage batteries let you tune heat to the cart\'s recommended voltage — important for live rosin and live resin (lower voltage preserves terpenes; high voltage burns them). Standard pen-style batteries are simpler and cheaper but cook every cart at the same heat. Happy Time stocks both at every store.
