I have a mxjo 18650, i am aware its a rewrap. I was wondering if it was safe to charge over night, I have a long work schedule that gives me 4 hours a day of freetime, and i can only get about an hour of charging in at the most. I was wondering if it was safe to charge it over night, its almost completely dead at this moment and i need to get to sleep in 4 minutes
Can you charge 18650's over night? need answer fast

I charge mine on a nitecore d4 over night and never had an issue I would say IMO as long as it is a good charger. Bring your charger to work 
Cant bring the charger to work :/ Very strict policies. Cant even have any form of tobacco/"Vaporized tobacco" On the property, except for in your car. And in North Carolina, you dont leave a battery in your car when summer comes around. I dont get bad cravings for a vape like i did with chew, so it doesnt bother me to wait until i get home but the charging wait is a problem haha.
I wouldn't leave the battery charging while you are not around to take care of a catastrophic event should the charger or battery fail.
It's only safe if you have a charger you can trust, and even then fluke things can happen some times depending on the condition of the battery. If your batteries are truly going under voltage as suggested by the "almost completely dead" comment - that would be a battery that should be monitored when charging.

If you must leave batteries charging unattended... which is a terrible idea.... but if you MUST... Get a charging bag or build a charging box. Google LiPo Safe Bag.
I used to charge inside an old computer case. I emptied the guts out of an old computer with a steel case and ran a short surge protector in through the power supply hole - and I cut a piece of tin to fill the remaining gap in the power supply hole.

I have tile flooring so I just pull the charger out onto the floor so that it would not be able to cause catastrophic damage should it spark or catch fire for some reason.
I'm paranoid. So if I have some that aren't done charging when I go to bed, I set the alarm for when I think they'll be done. And, yes, I get up and go get them. I also have the charger on a granite countertop.
When a battery explodes, it can take off like a rocket. - Because of what I do for a living (communication equipment), I've seen all sorts of exploded batteries from lightening surges. A 6 foot flame is entirely possible from an 18650. Finding parts of a battery as much as 20 feet away or farther after one blows up is pretty normal when the nema box is a snap shut instead of lock shut.
Get a lipo bag or build a metal box with a latch and plenty of room inside it plus some venting to absorb the concussion of any explosion that might ever happen.
I never charge my batteries when I'm not home. Just something I've got in the habit of doing and will for as long as I vape. I also have a lipo bag sitting close by in case of an emergency, with batteries I take no chances.

Do what I do, if you ever need to charge batteries over night, cover the batteries the kids rabbit cage. If it blows, the fluffy little turdbasses will take the brunt of the hit and you'll save on rabbit food. And you can make a nice hat with the remains.
I have always charged my batteries over night (oh yeah, living on the edge and they call me mr. Danger) never had a problem... Its not like every battery is gonna fail when you charge it, it just happens once in a while... Get a good charger and relax... The batteries were made for being charged and the charger was made for charging batteries...
I always charge 18650 in my Cloupor mini overnight. It usually take 4-5 hrs to make it full charge, while I sleep 7-8 hour. So it will be around 2-3 hours of FULL CHARGE but still plugged. I know it's not the safest way but it's a necessary for me. I do this almost on consecutive 20 days.
Ammo crates are often used as charging/storage pods for lipos. They're the perfect match for you description.
If a Charger is Properly Designed, uses Quality Components, has undergone Stringent Quality Control Tests, and is in Perfect Working Order, and if your Batteries are New and in Perfect Condition, then there should Not a Problem with Leaving Batteries in a Charger once they are Done Charging.
But...
Not All Chargers are so. And Even the Best Charger Can Fail after a Period of Time. And Batteries start to Degrade from the Moment they are Made. And with Every Subsequent Charge/Dis-Charge they do.
So I guess the Question becomes: If My Charger or if My Battery decides that Today is the Day to Fail, do I want to be Asleep or at the Store when it Happens?
I'd never charge a battery unless I was around (and awake) to monitor it.
Lipo bags are great for charging mods with built in batteries, like an MVP, iStick, eGo, etc, but DO NOT put a battery charger in a lipo bag! Battery chargers are not designed to be used in an enclosed space. Battery chargers give off quite a bit of heat which will accumulate inside the bag and can cause serious problems.
