Single 18650 Mosfet Mech Mod

[Uzzi_G]

I want to know if this is possible and exactly how. Like what mosfet should I use and the resistor. I'm converting a dead mod into a mech, I have done series mechs before with mosfets but failed with my first attempt at a single battery.

Just minus a battery Dont forget to share your progress.

You need the correct mosfet that supports a very low gate voltage(VGS(th), a lot of them are 4.5v and higher.
eg the IRLB8743 has a Vgs of 2.35V and a low DS resistance of 3.4milli ohms.

The mosfet/s you looking for is called "N-Channel Logic Level" - a part number with "L" in it as the one @blujeenz mentioned.

Yeah he needs the IRLB3034 which is the most popular one for us vapers and then a 1/4w 15k resistor and whatever switch.

Will I be able to find this mosfet in Mantech?

In SA if you can't find it at Mantech you will definitely find it at RS.

Awesome, haven't got down to finding the datasheet but would it be safe to run in a series battery configuration as well as parallel?

They have listed in CPT but no price for it.

Google will get you the "infineon pdf" datasheet, supports 40V so should be good for series too.

The maximum allowable gate-source voltage (VGS) for the IRLB3034 is +/-20V, so you're more than safe at 8.4V.
