If you want to build your own 18650 battery powered induction heater, this is a list of parts you are going to need. There are various how-to guides to actually make an induction heater out there already, just have a look around – and please ensure you know what you’re doing with this one!
These components are available in our shop. We also sell full DIY kits with all the parts required and a wiring layout – just to make your build a little easier.
This is a challenging but achievable build for someone with a good amount of maker knowledge; who has a soldering iron and isn’t afraid to use it. We have created a wiring diagram to help you assemble the parts correctly as well as some other resources to help you on your way. Having said that, lithium batteries can be very dangerous. If you don’t fancy getting down with the hot tin, then feel free to head over to our shop and pick one up ready baked.
You will also need an enclosure (a case) of some kind and some wire (it’s a 12V 6A system, so something reasonably chunky, except for the button and LED, those bits are low power).
We very strongly recommend against using Lithium polymer (LiPo) batteries as some guides suggest (the type used in drones and other R/C stuff). These things just aren’t very safe and have to be removed from the device for charging. This build involves making a Lithium battery from three 18650 cells. Lithium batteries can be extremely dangerous. If you haven’t got any experience making lithium batteries you should do some research first. I recommend Micah from ebikeschool.com, he has a book and lots of great videos. Be very careful, these things are not for messing about with. In case you were just scanning this bit and didn’t catch my last comment:
