HI all, like i said in my intro I'm pretty new to to mech mods. My question is, how far should I let my vtc4 drain down to? I have read some conflicting information. I let it get to 3.5 then stick on the charger. Is this where I want to be?

Yes, 3.5v-3.6v, that's a good number for me.
You don't want to let it go below 3.0v or the battery chemistry becomes stressed. That probably is not the correct wording (so to speak).

I try to get mine back in the charger at 3.5v. It's not as much the discharge as it is the recharge heat and stress that you want to avoid. Shorter times in the charger mean longer vaping time before you have to replace it.
Once it reaches 3.5v, it's not long before the discharge curve drops quickly.

I have noticed a drop in performace after mine drop below 3.9v but that has more to do with my mod than my battery. When mine hit 3.8 or so they get swapped out and get dropped in the "to be charged" box. My sigelei also reads .1v low so at 4.2 it reads 4.1.
Over drain an imr regularly, and the batt looses the capacity to recharge and hold the charge. It doesn't hurt the batt to charge it to soon either. When going to work, will usually throw in fresh batts on all the mods I take.
My LUC 4 charger reads 4.2v when my old AW's are charged fully and also if I reinsert them into the charger after the Provari tells me they are 3.9v on the first battery check after insertion. What makes me think they are down in the capacity curve is that my Efests and my EH's all read 4.1v in the Provari after reading 4.2v in the LUC 4 charger.
The real telltale is that the AW's are giving me about 4 to 5 hours until 3.5v and the Efests and EH's are giving me 10-12 hours of vaping to 3.5v. The Efests were purchase within a week or two of the AW's and the AW's are real AW's from a reliable vendor who knows about clones and sifts through the hype.

I dont check mine.
I feel a voltage drop and then usually get it in the charger after a couple more vapes

You can charge at any time. The generally accepted optimum voltage level for charging around here is 3.5v. Past that point it's not long before it drops to 3.4v and then on to 3.3v. Shorter charge times create less stress on a battery.
Got it..One last thing. Is it supposed to read at 4.2 on a full charge correct? I have a battery that will read up to 4.10 is that ok?
Technically, Yes. If you check it right off the charger it should read 4.2v, but your charger manual will tell you what the cutoff is. For some, you might read 4.16v or some other odd number. If you insert it into most VV mods it will be checked under the load of the atty resistance and read a fraction less. My Provari reads 4.1v every time when I put in a freshly charged battery.
Good to know. I was hoping I didn't have to throw it away given its only a few weeks old. Thank!
If you get 4.1v or higher after charging, your batts are probably fine. That will drop over a year or so as you use them and they begin to weaken. The only issue is charge life. When you get noticeably less vaping time, start to shop for new ones.
You can extend the life by putting them on the charger as soon as you notice a drop off in vapor and flavor.

After reading this thread that is exactly what I have been doing. As soon as I can tell there is a drop, I throw it on the charger. Its kind of nice because there is less charging time.
