you could use a mosfet and a resistor to help with safety! :) or at least a mosfet

and since you can't adjust the temperature I would use like kanthal wire so you don't get the nickel too hot and let off bad stuff

Very cool I am making it now. I have laptop batteries. I have taken apart full charge . will be perfect. Thank you so much. This is so helpful to me.

I will thank you.

if you're not careful those batteries are going vent and go bang.

True if battery is lithium like this video :


I'm sure this is a possible outcome, like when 2 9v batteries get stuck together. But the coil acts as resistance, doing the work before returning to the batteries. What are the chances of them shorting out in this setup? Would there be a better way to keep that from happening?


What kind and what size wire did you use?
