510 Thread Batteries

A 5

10 thread battery is the standard power unit for screw in vape cartridges, named for the universal 510 thread that almost every cartridge on the market uses. If your cartridge screws in, a 510 battery on this page will run it. We stock reliable, tested units for Canadian buyers, sold strictly as hardware with no cartridges or contents included, shipped tracked to every province.
What separates a good 510 battery from a cheap one
Three things: voltage control, capacity and build quality. Variable voltage between roughly 2.7 and 4.0 volts lets you match power to your cartridge, because thick oils want more heat and delicate terpene heavy carts want less. Capacity in the 350 to 650mAh range covers a day or more of typical use. Build quality shows up in the details that cheap units skip: solid center pin contact so cartridges sit flush, preheat modes that warm a cart gently instead of scorching it, and pass through charging over USB C.

Button versus draw activated
Draw activated batteries fire automatically when you pull, with nothing to press and nothing to explain. Button activated units give you manual control, preheat functions and voltage stepping, which experienced users prefer. If this is your first battery, draw activation is the simple choice. If you know exactly how you like your cartridge to hit, buttons give you the control to get there. Either way, buy from a retailer that stocks authentic units, because counterfeit batteries are where the horror stories come from.
Start with our staff pick
The Iguana Smoke 510 pen is the current staff pick: draw activated, pocket sized, reliable center pin and a battery that lasts. Keep a quality charger on hand, and if you also run flower, our dry herb vaporizers complete the kit.

Battery safety in plain language
Lithium cells are safe when treated properly and unforgiving when they are not. Charge with the included cable or any certified USB C lead, never overnight unattended, and never on a pillow or couch. Store batteries upright, away from keys and coins, and retire any unit that gets hot during normal charging, smells odd or shows a swollen body. Health Canada publishes practical guidance on battery safety that is worth two minutes of your time. Every battery we sell is authentic stock from verified distributors, which is the single best protection.
Where the cartridges come from
Not from us, and that is deliberate. Batteries are legal hardware. Cartridges containing cannabis extracts are sold only by provincially licensed cannabis retailers in Canada, and unregulated carts are the one product category we tell customers to avoid entirely, because you cannot verify what is in them. Buy the hardware here, buy the contents from your licensed store, and the whole setup stays safe and legal.
510 battery FAQs
Will any cartridge fit these batteries?Any cartridge with a standard 510 thread fits, which covers nearly everything sold by licensed retailers in Canada.
Do you sell cartridges or oil?No. Batteries ship empty as hardware only. Cannabis products are sold exclusively by provincially licensed retailers.
What does preheat mode do?It warms the cartridge at low power for a few seconds before firing, which protects flavour and helps thick oil wick in cold Canadian weather.
How long does a 510 battery last per charge?A 400mAh unit typically delivers 150 to 250 draws. Bigger cells stretch further, at the cost of pocket size.
Why does my cartridge sit crooked or not fire?Usually a dirty or depressed center pin. Clean the contact with a dry cotton swab. Our units use solid pins specifically to avoid this.
