So I just picked up a ipv mini and got a 18650 for it. I notice on the battery it says it's 3.7V, but the charger I bought for the batteries has a switch on it to change the charge from either 3.0V or 4.2V. I am wonder what's setting I should have the switch set at. Bear with me please as this is my first mod that uses a removable battery.
What to set charger at.

I have a trustfire charger. I know some people consider them a "cheap" charger but it's the only one I could afford at the time of buying, though that's irrelevant.
A fully charged 18650 will read 4.2 volts, so I'm guessing the 4.2v setting. But would need to know the charger type as previously mention by another poster.
Edit: I had the trustfire charger as well. Always kept it set at 4.2v if I recall correctly.
Is it the TrustFire Multifunctional Charger? This one?
If so, read the manual. Set to 4.2V, as you have full charge 4.2V batteries. It will charge them with 500mA.

Haha didn't even notice the manual in the box lol. The manual does say if it's a Li-ion battery to use 4.2V. Thank you both for your help. And thanks for reminding me of the manual I somehow didn't see.
Welcome,
A note to battery safety here as I ran RC cars for many years and most used the same battery technology that is used in ecigs today (actually some of my battery packs were 18650's in series)
Batteries have a Minimum and Maximum charge level, typically this isn't an issue as most are commonly known, with that said lets dive in to sealed batteries.
If you overcharge a liquid cell battery ( battery with acid in it) then it will just evaporate the acid off and worse case is you end up with a dry battery.
Dry cells don't have anywhere to vent the gases, so you can see the issues here with that one.
Look on your battery, somewhere it says " x.x v", in some cases its 4.2 and some its 3.7. To push a dry cell beyond its maximum charge can be a gamble on what will happen, maybe you'll get lucky and nothing, maybe the battery will internally stop working and worse case is it internally shorts out (had an RC pack go up because I set it on the wrong voltage once myself).
Digital chargers are the best to go with, they won't overcharge the battery and most will read the cell to figure out what the maximum charge is for that cell (any quality charger will do that anyways). I'm not sure on the mechanics of how it does this but I do know they work very well as eventually all my RC gear was swapped up to this. Also your digital chargers offer fault protection so should a cell register as bad or iffy then it won't allow charging of that cell any longer preventing possible issues.
Trustfire is a good charger
Nitecore is what I currently use and is a good charger as well.
Basically anything without a voltage charge selector switch is good and will do you well.

I have an AWT flathead. On the battery it says:
IMR 18650
3.7V 2500MAH 35A
High Drain Rechargeable battery.
I know it's a 3.7V but my Trustfire charger only has options for 3.0V and 4.2V.
