sorry if this was already covered
Okay all you K100 owners maybe you can help me out. I bought the kit that came with the small and big battery and charger with two cartos. I've been running the evic up to now but I've noticed a couple of odd things. I'm not experienced with mechanical mods so maybe this is just normal.
The grey 18650 battery it comes with (2000mah) doesn't give me much vapor or throat hit and the little battery (900mah) although still 3.7v gives me even less. If I put in the Samsung ICR-18650-26F I get great throat hit and vapor. Is this common with different
batteries or does it sound like there may be something wrong with mine? Also I've charged the little battery all night and the light on the supplied charger never goes green. I don't know if it's the charger or battery or just me as I have no other charger to use on the small battery.
I've basically just decided to use my samsung
batteries in it but that kind of leaves me short on my evic.
was reading through the thread when I caught wind of this. So the batteries the kit comes with are pretty bad. if you run them on anything with less than 1.8 ohm resistance, you are over-drawing their capacity and risking a fire/explosion. The samsung battery is a bit different, I'll break it down for you here.
Things to note: C value lets you know the max drain you can place a battery under. Lower resistance = more drain (less stuff blocking the flow of electricity). For example your Samsung battery has a C value of 2. (Googled it.) From there, we look at the mAh of the battery, (2600mAh) and multiply that by the C value (2), gives us 5,200 mAh or 5.2 AHs. (m=mili, A=Amp, H= hours). Thats the MAX drain your battery can support.
So, lets look at the atomizer. The one it comes with is 2.2 ohm resistance. The battery is 3.7 volts. Divide 3.7 by 2.2 = roughly 1.7 AH. You're in the clear for the Samsung. The Kamry battery has a C value of 1. (Math again), and your running near the max, so the battery will not perform as well (and get hotter.. possibly (unlikely) burst because it's a crappy Chinese random battery).
You could possibly even get away with using a dual coil build ( 2.5 ohm coils on each side) with the Samsung battery. I wouldn't go below 1.25 ohm resistance (dual coils = divide by two... 2.5ohm each side = 1.25 total) with an ICR battery cause then you're just asking for trouble.
As for those batteries, neither have protection. So if you do build something, screw it into your evic first and make sure there aren't any shorts (or buy a fancy resistance reading gadget).
P.s. I learned all this the hard way, been vapeing on a dual coil (0.7 ohm) Nimbus drip atty using the stock battery. "Almost" vented the battery lol. So since you've bought a mech, my advice would be to buy a battery rated for 10amps or higher and IMR (Not ICR) simply because IMR will vent ooze (during a soft short... hard short will blow up anything) and ICR vents fire (which causes a chain reaction of more fire and then Boom.) I wouldn't bother with protected batteries, if you feel iffy about being unprotected use a short-stop chip or two penny safety tip switch. (they limit amps to around 10... if it goes over, they cut the power).
P.p.s. Pretty sure an eVic won't work with anything below 1 ohm resistance (it'll assume you have a short)
