This MFUSED cartridge is larger than usual, like 1cm in diameter. It threads onto these 510 batteries but doesn't trigger them like normal (5mm?) cartridges. Is there a different battery for wide cartridges like this?
usually they're a universal fit. sometimes having the cartridge backed off from tight improves air flow. they do make the bigger style pens that are the same outer diameter, bigger battery is all you're gaining with that
This would probably do it. It's got two ports, one internal the other one external. https://stacheproducts.com/products/skruit
is there a hole at the bottom or just around the thread ? Some cart wont work on batery who need bottom air flo too. i never try those cause i prefer refill my own cart.
