    So basically I live in Norway and I want to build a dual 18650 parallel mod and I was going to buy everything from eBay, but as I've read that there are many counterfeits, so I decided to buy parts from fasttech. But here comes the problem, you can't buy the IRLB3034PBF from fasttech. Does anyone know of a website that I could buy them from with low cost shipping as Digikey and Mouser have very expensive shipping.

    Also if I would for example buy the mosfets from eBay, what could be the worst case scenario with these mosfets malfunctioning?

    Hey Tymec. Search by part number over at Many times I've heard of people getting counterfeit components unfortunately from Ebay. A fake part may have poor performance and the component itself may produce excessive heat due to being a higher resistance (RDS ON).

    I'm no expert, but often times when MOSFETs fail, they let all the current through. The whole point of using a mosfet is to avoid the button welding itself, and failing MOSFET is even worse. I know the risk is far smaller though, but really, you don't want the mod to fire in your pocket.
