I use a Kamry K100 Mech with the Kamry resetting fuse
The batteries I use are AW 18490 or 18350 but vape with a 1.8 ohm Smoktech AVO tank. No RBAs yet--I'll get there eventually. For vaping/drinking/playing tunes--I load up an Efest IMR (LiMn) 2000mAH battery rated at 5C. Not sure if it will put out 5C or (5x2,000mAH)
but I don't need 10 amps. The little 350's are rated for 4 amps of draw so I'm at around half the max draw. Generally speaking, I don't like to tax a battery past half it's rated maximum for several reasons. First is voltage drop gets excessive, the operational life drops off drastically and as the batteries age, they lose capacity. Lost capacity means the batteries struggle to provide the output and the C level rises.
Eventually, I am going with 1.5 ohm clearo tanks and will give RBAs a shot with single/dual micro coils and cotton wicks. My plan is around 1.2 ohms but with variations--I don't want it to drop below 1 ohm. My battery of choice will then be the AW IMR 18650 1600mAH battery when doing the RBAs. Get a fully charged battery in the unit, fire it up and it could be hitting around 4 volts or so and blow past 4 amps easily. Even if I have brain damage that day, the AW18490 IMR battery can handle that even if it is an old battery. The little 350's--in theory, handle that also but I don't want to try!
I've only blown up one LiMn (IMR) battery, a Milwaulkee 28.8V 3.0 amp hour drill battery. Although I did not burn the building down, the very loud POP when it departed the earth did cause excessive pucker factor. After that, I went with DeWalt power tools and the A123 Systems LiFePO4 to solve that problem.
My dream mech does not exist--an Electric Angel type side firing switch mod with built-in automotive style fuse holders. Figure there is
enough space in the head to hold a 5 to 10 amp fuse and a spare when bad things happen. For now I use the Kamry resetting fuse or the 2 cent fuse--because my face and house is worth protecting.
Granted, I would love to build a quad coil RBA at 0.3 ohms and vape it. For that madness, I'd use a 26650 LiFePO4 battery since they can put out 30 to 40 amps without flinching. Getting a real one, a charger to charge the 3.2V cells and not cook things at 10+ amps and over 30 watts would be a challenge. With all those 26AWG coils in such a tight space surrounded by metal, you can bet I'd want a 15 amp fuse somewhere!
Everything breaks--coils, insulators and switches...fuses were not invented to make money but to keep the consumer alive to keep buying more stuff! Be careful out there and keep a spare fuse or three laying around.
