Will a 2G cart fit a regular 510 battery?
Most 2g carts use standard 510 threading, but their wider size (up to 14mm) means not every battery fits. Stick with ones labeled "2g compatible" or "wide cart compatible" to avoid issues.
What voltage should be used for 2G carts?
Start low at 2.5–3.0V for thick oils and live resin to keep the flavor pure. Distillate hits great at 2.8–3.3V. Lower = better taste and terpenes; higher = bigger clouds but faster oil burn.
How long does a 2G cart battery last on one charge?
A typical 650mAh battery gives 150–250 puffs—about 3–5 days for moderate use. Heavy hitters recharge daily; light users stretch it to a week or more.
Is preheating needed for 2G carts?
Not mandatory, but it's a game-changer for thick oils like live resin or distillate that can clog or separate. A quick 10–15 second preheat melts things down for smooth, easy pulls.
Can 2G batteries also vape wax?
Some can—if they've got variable voltage hitting 3.8V+ and enough power (650mAh min). Lower-voltage oil-only batteries won't cut it for proper wax vaporization.
