I see a guy stuffing a 30 amp fuse in the socket after he keeps snapping 10 amp fuses 
. These are the kind of things that go through my head .

For sure. Have to press the limits to the max.

The only way to prevent that is to use a specially modified fuse block and fuses, which kind of defeats the ability to go to the gas station and get a fuse. However, you are limited by the output of the battery and if you have a dead short, won't a 30 amp fuse blow the same as a 10 amp fuse? I realize it will take more time to blow, which could/would cause damage to the battery, but will it not still provide some level of protection? (Read allow you to keep your face.)
A friend of mine uses the term "fool killer" to describe people that do stupid things then get hurt or worse. Fool killer going to get him.
I like to embrace Darwinism. From the Free Dictionary: "Dar·win·ism (därw-nzm)
n.
A theory of biological evolution developed by Charles Darwin and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Also called Darwinian theory."
Good job Dibby and Seanap, looks like I will be off to the autoparts store today. Also I like the term Fool Killer too, that is a good one
UkiePaw, use this to play with some numbers. Compare a .4Ω coil @ 3.3V (fresh batt. w/out mod) = 27 watts . . .. to a .6Ω coil @ 3.9V (fresh batt. modded) = 25 watts . . . . . .say, for example
Ohm's and Joule's Law Calculator
Here's some v-drop #s for comparison
Ω : vdropw/spring : vdrop modded
1Ω : .4v : .13v
.6Ω : .6V : .2V (estimated)
.5Ω : .75V : .25V (est)
.4Ω : .9V : .3V

Rob, I'd say you can't overprotect people from themselves. So long as you are providing a safe solution and making it clear to the buyer about the fuse requirements you are safe on your side.
How can you avoid a wise guy from stacking an IMR 18350 with a protected battery on one VV Reo Grand?
There was a guy about a week ago in the provari sub-thread bragging about how he was stacking protected batteries on his provari and it was working fine. Should provape stop selling the extended cap so people can't do this?
just saying

I know it's your job to worry, Rob; but people will always find ways to hurt themselves. It's not necessarily your job to outwit them. (sympathy smiley)
We can easily establish and recommend fuse ratings/parameters; For the time being (without tests on each), we know the 10A is reasonable.
I would also point out that you could worry this to no end; only to find that someone threw an ICR battery in their car's coin compartment. . . . . . . . Darwin will happen.
Yeh, i was working on the below numbers
Stock with 4.2v - 0.9vdrop = 3.3v @ 0.4 ohms = 27.225 watts
Modded with 4.2v - 0.0vdrop = 4.2v @ 0.65 ohms = 27.138 watts
I never took into account the modded 0.3vdrop.
Should have been Modded 4.2v - 0.3vdrop = 3.9v @ 0.56 ohms = 27.16 watts
Doesn't sound a lot but modded unit would only be drawing 6.9amps instead of 8.25 unmodded.
Not sure what that means but guessing its a good thing.

V-drop increases as resistance decreases. The difference you see in Amperage = battery life
Let me refine it first. There was alot of adjusting involved
Don't take this the wrong way pdib, especially afetr all the hard work you guys are putting in, but, say for example I like my vape at 27 watts I would have to run a 0.4 ohm coil.
If I went down the modded route I could run a 0.56 ohm coil to vape at 27 watts.
My question, being an electronic noob is, what is to be gained other than longer battery life.
Say you like to vape @ 40 Watts. Try that.
And the battery life.
It's like this, UK, I like to drive at 35mph, so you can keep your Ferrari. Meaning, the differences are hard to put your finger on; but the difference in performance is tangible.
Other than better fuel efficiency and increased performance, no reason . . . just for fun.

Actually, tho, your numbers were off (and mine were ruff estimates). It would be more accurate to compare a .4 ohm build to a .6 modded.
Yeh, I get the fun bit but other than that and
improved efficiency, better performance, increased battery life and bettering an already fantastic product what else is to be gained ?
Only kidding, I will be the first to jump on the fuse mod if and when it becomes production ready which I am sure it will in some form.

Yep. I would say that's the least gain, but easy to do if you're rebuilding anyway.
