If used in a mechanical, you might find you'll want to recharge at minimum 3.6 or 3.7 Volts. I typically recharge at 3.8 in a mech.
In a regulated, I usually recharge at or before 3.5 volts....
Bear in mind that if you run it down below 2.5, it's considered by many to be unsafe to recharge and not safe to use.
The batteries we use now have very little "memory" so it's not important or recommended to "run them down" before recharging as conventional rechargeable battery wisdom used to dictate. You can quite happily charge them after only "vaping the top off them" (just discharging by a few points)
As for the charger, I'm not familiar with their IQ charger, but Nitecore makes good chargers in general.... good choice. Might you mean I2?

Mine normally are 3.2 to 3.3 volts when I take them out of my Sigelei 100 watt to charge.
I don't quite know what you mean by a "Generic"charger but Nightcore make a great device!

The rib at the tops of re-wraps have been off, as far as size and depth, but really, I would wonder where they got them from, since none have been available for quite a while...
VTC5's are 20 amps...why chance getting a fake which most likely yours are..Go with some Samsung 25R's or LG HE2's which are also 20 amp max, and be done with it...they are less expensive as well...I get all my batteries from liionwholesale.com...best prices you will find on authentics.
The charger is just fine..far better than a trustfire or some no name charger you call generics.
To answer the charge question this depends on if your using them in a mech mod or a regulated mod...In a mech dont go below 3.6 - 3.7v for safety reasons...in a regulated you can go lower but for best battery life try to charge around the same voltage.

Lightningvapes has legit vtc3 and vtc4 batts. Superior to the vtc5 even if they are real.
So does properly interpreting data. The testing showing vtc5's overheating at 30 amps also shows you have to draw a continuous 30 amps from them from 4.2v all the way down to 2.5v non stop. A regulated device won't allow that to happen and in a mech the current starts falling off as soon as the voltage of the battery starts dropping so maintaining a constant amp draw isn't possible. The conditions of that test don't come anywhere close to replicating the conditions that exist when a vtc5 is used for vaping.

When my mechs get hotter than i like i pull out the batt and realize its cool to the touch. Its the atty heating up the whole tube. When thermal runway or venting occurs the battery heats up way past any temps you can comfortably touch with your hands, ive never heard of batts spontaneously combusting, have they? Furthermore i alway heard vtc5 was a 20a with a higer mah. Never actually used a vtc5 when everyone was raving about them i had a stack of vtc3s i couldnt afford to just switch out. Didnt start with vtc4 til i got a batch of fake ass vtc3s. Used lg he2s until like 2 or 3 weeks ago when i was shown the light to vtc4s.
To finish the thought, the whole 'conditions aren't the same' logic can be applied in the other direction. I doubt the test included encasing the battery in a thermally conductive and insulating metal tube with a closely attached heating element and then holding the button down indefinately. I don't agree with the idea that anything above a certain number is always unsafe and anything below that number is always safe ragardless of any other factors. Ratings are approximations made by someone else that shouldn't be blindly accepted as gospel. Knowledge must be had and judgement must be used when messing with a handful of energy.
IF you're vaping at .5 ohm or higher then Samsung 25R's are probably the best battery you can get that have a 20 amp max rating.
IF you're going to vape below .5 then consider some Sony VTC4 batteries.
liionwholesale.com is where i buy my authentic batteries from..Best prices you will find as well.
The ipv2 has a max input current of 20 amps. You don't need a 30 amp cell regardless of what the resistance of your build is. Coil current and battery current aren't the same thing in a regulated mod. Get quality 20 amp cells. They'll cover the mods requirements and give you longer runtime than a vtc4. LG HE2's or Samsung 25r's would be good choices.
If you're talking about this post,
he screwed up the link. I would be skeptical of centralvapors.com. Their site let me add a vtc5 to a shopping cart. Makes me wonder if they're in the business of selling fakes.
How low of voltage should I let it get before I recharge? I've got a note core in tell I charger. I don't want to damage them. I know that they should only discharged to a certain voltage but what is it? Anything else I should know to do to keep them health?

Well, MXJO batteries are rewrapped cells from LG, anyway. But I haven't heard of a problem with fake MXJO anyway.
And as far as the VTC5s, I don't know that the site you got them from is intentionally selling fakes, but I would be suspicious of the batteries anyway. Sony hasn't made them for a good while now, and there have been PLENTY of fakes going around. So unless they have a huge stockpile of them from a couple of years ago, I would not believe that you have authentic VTC5 batteries.

Also, with a very low build the tube itself and the connections will have some significant resistance, and power will be dissipated in the mod itself.
