I don't charge batteries, not even my cell phone, overnight but if I did it would be in a battery bag for sure.

The long and short of it is...don't skimp on batteries or charger. If you go with good batteries (AW, Panasonic, etc.) and a quality charger the chances of anything happening is extremely low. However, not charging your batteries overnight will always be safer than doing so...the choice is yours. For the record, I charge mine overnight and sleep soundly.
And to reiterate what others have said:
Do NOT use a charging bag. These bags are designed for chargers where the battery sits outside the charger and only the battery is intended to be put in the bag (think RC airplanes and similar devices). The charger needs airflow to keep cool and putting a charger with batteries into one of these bags is asking for disaster.

The Nitecore i4 is kind of overkill for anyone that just switches between two batteries. The i2 is exactly the same as the i4, just less capacity (takes 2 instead of 4 batteries at a time).
Thanks for the info on the charging bags.
I've seen the pictures here of burned counter tops and carpets that cost lots to replace so it wouldn't hurt to place them in a pan, serving dish or large ash tray while charging.

Overcharging batteries can cause the batteries to not work correctly. Like in a cell phone, if you constantly charge it overnight you'll notice that the battery will start holding less and less of a charge. After about a year of doing that, your battery can start expanding and that's what leads to fires and explosions.
The liposafe charging bag I use is fine and an added safety precaution. I'm not sure what charging bag you're talking about, but using a liposafe charging bag is actually a good measure to ensure extra safety and has been recommended on the forums many times and lots of people use them. The one I use is designed for the charger to sit inside it. The cord comes out through the side of the top flap, which also allows air into the bag. It doesn't get hot and has never been a problem.
I also put the bag into a pyrex dish when charging. There's no "asking for disaster" here. Its a safety measure. Use common sense - you can leave the flap open quite a bit if you want.
We've seen reports of exploding batteries. A liposafe charging bag will contain it if it happens.
I recommend using one of these bags.

Good idea. Even with the bag I don't do overnight. I used to charge overnight - but its not the wisest thing to do.
I rarely charge overnight. But, I do use a metal tin to set my charging batteries in either way, just in case.
So you are saying that I SHOULDN'T use fireplace starter logs soaked in gasoline as a base for my unprotected el-cheapo batteries and charger, and set it on my wooden entertainment stand for 3 days at a time (just to make sure I have a fully charged battery when I need it)
Sorry..There is no sarcasm font!

Do you happen to have a picture or info on your liposafe bag. I've yet to see one that is meant to hold a charger inside of it. Liposafe bags are originally designed for hobby grade RC lipo batteries to my knowledge. These generally have a charger with leads that you'd run into the bag, leaving the charger outside of the bag. The reason you'd never want to put a charger in a bag is because they will generate heat, simply because no charger can ever be %100 efficient they will generate heat as a byproduct of inefficiency. Some more than others. You may get away with putting your charger in the bag, but i would recommend against it in general.
I generally charge mine right before bed. It only takes about 2 hours and when it is done I take it off the charger and turn the battery off for the night and place it in a cabinet in the kitchen. I have a knock off Ego, and the instructions for charging say to not over-charge it. I found that this works best for me, so that I have plenty of charge for the next day of vaping. A 650mAH battery will last me 2 days without needing a full charge. I plan on getting a 5 pack of 650mAH batteries from fasttech(waiting for it to come in the mail) so that I can have a back up to vape on before bed. It is hard to charge for 2 hours before bed and not want to vape.
LOL, you guy either overthink this or I underthink it. I just toss them on the charger when the warning light comes on and when I notice it's full, I take them off. Sometimes they're in overnight and sometimes during the day. My ego passthrough is plugged in when I'm at my desk usually. The charger I got with my Provari charges the single batteries. I just kind of go with it. Yeah, it might decrease their lifetime if I leave them on or whatever but they are cheap and I need my brain power for more than chasing battery charges 
I usually don't charge them overnight and unplug when the light turns green. But occasionally I do charge them overnight or unattended, but I don't feel too bad about or think too much of it when I do. Heck I always charge my cell phone overnight. Normally these things are pretty safe, so it's a matter of how much risk you are willing to take.
It's like, do you unplug (not just turn off) all electrical stuffs and shut off the main gas supply when you go on a vacation, like they advise? And if the vacation is in winter time, do you shut off the water main and drain out all your pipes, like they advise? Do you tell your neighbor about the vacation so they a) pick up your newspapers on the lawn and b) watch out for suspicious activities, like they advise? Setup random on/off light switches to simulate human activities (and don't forget to tell your neighbor who is keeping an eye on your house about this)?

Another noob here with the same 2 questions: battery charging and keeping up with your thread posts.
Thanks to all for the great info.

True. On the other hand, we're all getting to where we have so much tech around, I'm not sure my PV batteries are the big worry? You should see the size of the batteries in my UPS.
Seriously, I'm a computer type geeky guy in a semi-rural area with iffy power. I have a UPS/line conditioner almost as big as the computer. The batteries are about ten times my Twists at least. Yeah, I trust it more than the charger for the Twists but electronics can fail. Any of them. Even cell phone batteries have gone nuts and people hold those things up against their faces alla time.
I do charge overnight. But, then, I also have a quality smoke detector I test regularly and there's a fire extinguisher on the wall behind me...

I do both overnight charging and charge during the day while home. It really all depends upon when I'm using my last battery and the other 2 are thrown on the charger.
No issue to date and been doing this for several months now.

As I said, the charger does not get hot in the bag when I use it. A lot of vapers use these and vaping vendors sell them. I bought mine from a vape vendor. I'm quite safety conscious. If the bag, or batteries in it, were heating up I wouldn't use it. I place mine in alarge metal dish or pyrex dish as well. I have one like this:

That site has instructions.
Also available here:
Efest LiPo Safe Charging Bag
This is similar:
http://indyvaporshop.com/liposafe-charging-bag.html
Liposafe charging bags like this are available from several vaping vendors.
The top flap allows for some airflow but is also designed that it will contain a fire.
I've seen reports of batteries go thermal more than once. I haven't seen a report of a liposafe bag causing it. I've seen one thread where some-one was concerned about a bag heating up - one out of several people who use them. As I recall from that thread - it was a multi-bay charger being used, rather than a two-bay.
