Hello. Being a 6 month vaper only, I have only used PV's with inbuilt batteries and replacable coils (mainly Kanger BDC's). These batteries seem very good to me and are easily rechargable plus coils are only a couple of dollars so I am curious as to why so many people are so keen on loose battery mods and re-buildable coils. Do they produce better vapor/taste, last longer or is it an interest/hobby type of thing ? or none/all of the above.
I am considering purchasing one along with some wire and wick but this is more of an potentially unforeseen (Australian) government law change plan B consideration which raises another question, are the loose rechargable batteries which are normally used similar to normal AA type batteries and can these be used if the situation arose.
I moved to an advanced set up in part because the batteries are actually less expensive. If you compare the set ups with built in batteries to "loose" batteries, it's cheaper to buy, say, 18650s (which I use) than the built ins. Like a Twist with 1000 or 1300 (think that's the big one now?) is around 25 to 30 USD. 18650s with as much as twice that capacity are half or a third of that cost. So they last longer on a charge and cost less to replace. The initial price of a higher end kit and charger and all is more than your Twists or such but the long term is much cheaper. A solid mod cam last a long time.
(Don't get me wrong, the kit that got me off cigs totally was Twist batteries with Vision toppers. They're good starters I think. The eGo style kits that is. But the battery cost is a bit steep over the long run.)
And, yeah, mods (or APVs or whatever... the fancy stuff

) can produce more power. I use dual coils and run at between 8 to 10 watts depending on the liquid. That's up to near 7 volts on my 1.5 ohm coils. It's more vapor and I like a "warm" vape. Some folks go even higher on wattage but I'm kinda "middle of the road" I guess.
And no, you
cannot just slap a "regular" battery in a mod. Some mods have very narrow requirements in fact. Using something just "off the shelf" could be dangerous. If it even worked (not likely, mod batteries aren't shaped like a AA or such, probably wouldn't even fit the device). But it's not hard to learn which batteries fit your mod and not hard to find the right ones. 18650s, for example, are one of the most common lithium batteries around. Used in a ton of things like flashlights and medical devices. I believe even the Tesla electric car uses 18650s (but a lotta them!).
I can't say anything about rebuilding coils. Never done it. Sounds tedious to me and I'm in that "middle age" thing where your close up vision goes wonky.

I use iClear 30s tanks. Replaceable coils that run me about 3 USD each. And they last a decent length of time for me. Not too pricey a thing.
Yeah, there's a "hobby" side for many (and it's a healthier hobby than smoking!). But there are distinct advantages to advanced systems. More vapor, more control over the temperature, less expensive battery cost, and a heavy vaper like I am, being able to swap a battery in a few seconds is nice. Done it enough now, it's zip, click, go.
