I just got a new nemesis mod, tesla atomizer, and AW 2000 mAh batteries. But before I try it out I wanna make sure 2000 isn't too much, I previously used at 5300 mah battery ( I was a noob, and didn't realize how unsafe it was) and needless to say, it blew out all my tanks and attys. so please tell me, is 2000 safe?
How much mAh is too much?

Mah is Milli Amp Hour... It's a rating of how long the battery will last between charges.
It sounds like you seriously need to read up on battery safety and ohms law.

hmmm okay.. mAh is the same thing as the capacity of a gas tank in a car... you have a car and it holds 4 gallons or it holds 50 gallons... the 50 gallon tank will allow you to drive longer... what you really want to know is what the horsepower of the engine is ( the Amps the battery can deliver)... if the battery has a low amp delivery ( lets say 10A) then you have a low HP engine... if the battery can deliver 35A, then you have a hi HP engine.... but unfortunately, most hi power batteries have low capacity( small gas tank) and low HP batteries have higher capacity ( bigger gas tank)... its a balance.... sooo, in a really wonderful world a battery would have 50A capacity at 5000mAh... maybe one day it will happen 
As others stated, mah is just a measure of battery capacity, it only affects the run time of your device before you need to recharge the battery.
If you have an AW IMR 18650 2000 mah, that battery has a maximum continuous discharge of 10 amps according to this:

That means you should not build coils below 0.42 ohms, and probably shouldn't go that low to leave yourself a safety margin. 0.5 ohm and higher would probably be fine though.
If your battery is an ICR or anything other than an IMR, do NOT use it, it's not safe.

where did you get a 5300 mah 18650? it may have been marked as that but that doesnt sound realistic. and the voltage output is what would fry your attys but since ive never seen an 18650 be anything but 4.2 on full charge... a lot of this just doesnt add up
through a google search there is an 18650 being marketed as a 5300 mah battery galled gun light. a candlepower forum member ran tests... and it was 1600 mah on a good day. still 4.2 volt so again no idea how you fried an atty with it
huh? you lost me on that one... one can take several 18650 batteries and parallel them for several thousand mAh capacites but only have 4.2 volts max ( and also increase the total Amp capacity)
right thats what i was saying. the only way a battery is going to fry an atty is if your pumping too much power to it. im not saying its related in any way to mah. what im saying is uless he is rebulding tanks at crazy low ohms, no 18650 is going to pump out enough voltage to fry it
the only thing I can think of is that your 5Kmah battery had a very good/high Amp capacity which could deliver the full 4.2 volts under load and burnt out your coils
Hi i'm still new to ecf but the only thing i can think of other than what has been stated would be a short in the top cap of the mod itself since it evidently killed multiple tanks and attys. i would check the 510 connection for a short or the battery rattle pin as sometimes they like to drift sideways and touch the ground. if you r using a hybrid adapter make sure that the positive pin in the atty is sticking out past the end of the atty
as to the original question yes 2000 mah is safe. i use sony vtc4 at 2100 mah and it is a 30 amp battery
For more info on the OP's previous batteries see his previous thread: Nemesis mod problems
yup those are the gun light or gtls whos actual mah tested at about 1600 mah
if it was that kind of short, only the battery would be affected, not the atty
ok ty bunny killer .... then i don't have any idea what would cause that other than what has been posted
if an atty coil gets trashed ( burnt) it is due to too much amperage flowing thru the coil, hi gauge wire (thin) cant handle alot of amperage. If a battery is capable of delivering a strong amp flow, the voltage drop wont occur and can over heat the coil in short order melting the wire....
kinda like supplying a garden hose with too much pressure/volume flow, it will burst. As with circuit board resistors, they have wattage ratings. If you put too much amps into a low wattage resistor it goes poof...
below is a picture of 2 resistors the tiny little thing in front is a 65 ohm 1/8W resistor, the big heatsinked gold thing is a 63 ohm 250W resistor
basically the same resistance but different heat capacities

Get a proper regulated mod with a screen and protection circuitry to work with before you go messing around with a mech mod.
If the 5300 mah battery blew out all your tanks and attys, it was not because of the 5300 mah.
The batteries to look for are the "IMR" type of batteries. These are the safe chemistry batteries.
And the problem with lithium batteries is not that they might blow out your tanks. The problem is they can potentially blow out your FACE.
After some experience vaping, understanding what is going on, you can try the mech.
Or if you seriously can't afford a regulated mod or regulated battery like the istick and have to use a mech for cost reasons, at least start off with a fuse.

You can pick up a kick or kick clone for cheap (basically drop in regulation module for mech). I've seen them for around $20
MAH ratings indicate charge capacity and usage life between charges. In a flashlight more MAH means longer on time for the flashlight. In an ecig, it means longer vape time.
There really are batteries that are rated at 5000mah and 7000mah, but they come only in 26650 sizes.
