I had the IRLB3034PBF in mind as well since it works. I assume R1 can be 15K since we are back to unregulated voltage. I found fuses for 9.5A as well, 2 x RGEF500 wired in parallel or if my battery specs change, the RGEF series of PTC seem a good starting point for me.

What I am finding, in my case, is using what is available.


The eGo T boards won't let you escape the 10 sec vape time limit by de-pressing at 9 seconds. :P
