I was wondering whether I should take out my batteries when the battery indicator starts going low or or if the device knows to stop using the battery at the right point, allowing me to trust that when the battery indicator shows that the batteries are dead and that they are not overused. I'm asking specifically for the smok Alien.

But now days and age, I am wondering if our new chips like the Alien (only came out a couple of months ago) can be trusted fully for the battery life.
Yes they can.
Do you have a dmm, test voltage, i charge at 3.6 volts or so. About halfway on most indicators. Shut-off by mod around 3.2 volts.
You may go either way.
Recharging at half point will increase useful life of your batts..

I actually used my batteries with the battery indicator showing approximately 95% used on the Alien and when I put them in my Efest charger it said they were at 36.4 which probably means that they would be at 36 when they were fully used according to the battery indicator for the Alien.
Don't go by indicators, most are not that accurate & rarely match each other. If you are in it for the long haul, you will get a volt/ohm meter.
As stated above, i don't use mine each & every time,, just when things get Dicey..

Well my charger has a volt reader. The efest charger 4 battery charger with the option of charging faster or slower. If I want to know the voltage I can just put it in the charger for a second.
I charge mine a 3.6V as well. For my iJoy Maxo315 it's about 1/3 of what the battery life displays.
On "Average" most mod chipsets shutoff at about 3.2v per battery. Some even though the battery recovery and hold voltage is about 3.5 to 3.6 or idle voltage, though when power is requested, especially higher amps, the battery voltage supply drops, aka voltage sag, below the 3.2v cutoff, most mods throw a low voltage signal or check batteries signal. However also, most mods on the market and especially the higher output ones like the Alien 220w, are way, in my own opinion, over speced, they can not reach these wattages constantly and still be safe, especially when you take into account on a regulated mod unlike a mechanical/unregulated mod, regulated mods pull their most amps the lower the voltage on the battery is. Nature of the beast of a regulated mod's "Boost Circuit", which what the boost circuit does, when the chip detects input voltage is lower than the voltage needed to reach set watts, the boost kicks in, pulling more amps from the batteries on top of available voltage, and converts these extra amps into raw voltage to "Boost" the voltage to the needed voltage for said set watts.
In all honesty, you have to look at what your mod, amperage wise at lowest voltage, advertises it can do, and what the batteries are actually capable of at said lower voltages. In general at a 3.2v cutoff per battery, 20amp battery max wattage is about 65watts per battery, 25amp is about 80watts per battery, 30amp is about 96watts per battery. Those are rough figures, but saying everything is ideal, you 220watt dual battery device at 6.4v lowest (3.2v X 2batteries in series),
20amp batteries and stay safe 130watts max constant wattage (65watts X 2)
25amp batteries and stay safe 160watts max constant wattage (80watts X 2)
30amp batteries and stay safe 192watts max constant wattage (96watts X 2)
and those are raw figures not taking into account the necessary voltage the chipset needs to operate which we call chipset efficiency, which most chips the average is about 90% efficiency.
(Watts Set/Lowest Voltage)/Chipset Efficiency Rating=Actual Max Raw Amps the Mod will need
To maintain 220watts consistently and be safe
220watts/6.4v=34.375amps, but take that 90% efficiency into account, 34.375amps/90%=38.1944amps <-- 8amps over what even the LG HG6's CDR is rated at, 20amp CDR battery you 18amps way over their CDR
220/7.2v=30.5556/90%=33.9506amps (3.6v per battery)
220/7.4v=29.7297/90%=33.0330amps (3.7v per battery)
220/8.0v=27.5/90%=30.5556amps (4.0v per battery) <-- a little above what an LG HB6 is rated at, but at 4.0v per battery you are not getting the best runtime, what maybe 5 to 10 minutes of vaping at that wattage range before you go over CDR once the voltage drops from 4.2v per battery fresh charge to 4.0v each battery?
Best advice I can suggest, get yourself a digital multimeter to read your batteries independently, see how each is discharging compared to the other in the mod, then plugin to the formula above what watts you are using regularly and consistently, and knowing what CDR rating of your batteries are (20, 25, 30?) you can figure out what voltage to pull and recharge them. Myself with my 150+ mods I've pulling batteries to recharge at about 1/3 to 1/4 charge indicator.

That's cool, does it sort of match up to the indicator on your mod?
If so, you are one of the lucky ones.
The real thing i wanted to address, was how far to discharge a li ion battery. Somewhere around 3.6 volts, which is above the Mods cut off point.
Good reading,,,Battery University,
No engineering degree required..
I'm not sure if I've read about about this but can someone explain to me how a regulated mod uses amps, say if it takes 2 batteries, each 25 amp batteries. Does the mod use amps from both batteries combined. I'm not educated enough. Sorry.
Depends on the configuration
Single Battery - Amps available
Series Configuration (most high powered mods Alien 220w, RX200, etc) - voltage is X number of batteries, but same mah and CDR of a single battery
Parallel Configuration (iStick100w as example) - voltage is the same of a single battery, though by theory mah and CDR should equal X number of batteries, but in truth with CDR you gain maybe 50% extra of what the extra battery can handle, ie 20amp CDR, 2 batteries in parallel safely would be about 30amps combined.
Note that the Alien discharges the batteries to 2.9v, so max 55w per 20-amp battery (assuming a 90% device efficiency).

And assuming you run the cells dry, you can choose to pull them before the mod tells you to.
Smok Tech chips are decent. only owned one but i was running the power at max.
moved on to the Triade DNA250 and was quite impressed the power and performance.
i run 3 batteries and get about 12 hours of cloud play. (RDA)
24 hours of normal use (TANK)

True, but there's always the risk of forgetting to pull the batteries in time. I'd not feel comfortable always having to keep an eye on my mod, possibly needing to pull out my batteries to measure the voltage with a dmm, to make sure I'm not endangering myself. I prefer using batteries that are suited for my power setting from start to finish. It's safer.

how long can I expect my batteries to last in my new alien vaping at 120w ?

Not really - the easiest way to find out is just to 'suck it and see' - you'll know soon enough.
I got mine recently as well and at around 90w I was getting 2 days out of a charge. But I guess it would really depend on personal use as well as wattage. I was at about 130 Puffs per day if that gives you something else to gauge it off.
