I remember I tried 75w for a few seconds with that battery, which definitely can't provide 75w. My vaporesso Target Pro didn't give any error or warning, but shouldn't it? Do high-end mods give an error when the battery can't provide the set wattage?
You won't get an error necessarily. Your mod does not know what type of battery you have and does not know it is pulling more amps out of the battery than they can safely handle. The batteries themselves will get too hot and either vent or possibly worse.

I sincerely doubt you'd get a warning, if you are lucky, your mod would just refuse vape anymore and just show empty.

You are also asking questions that can't really be answered, I'd say it's certainly true that if you've pushed a particular set of cells past their limit and their performance is growing poor, well, that DOES increase the chances of the batteries venting and other worst case scenarios. And, they ARE worst case, but they do happen.

If I were in your shoes, I would stop vaping those batteries it's not even the "single push" to 85 that worries me MOST, it's kind of the more routine, daily overstressing of batteries. Although, neither scenario is exactly GOOD. To me, it would not be worth the safety risk and I would retire them, especially given you have now been given better battery education, and a list of reputable suppliers. DO THAT.

Whether you use them is up to you, but personally I wouldn't. Even if the risk is fairly small, (and no one can really assess that given how long those batteries have been stressed) well, I just... I wouldn't. I like my hands, mouth etc. Just the way they are.

Good luck and the good news is, reputable vendors usually have fairly fast shipping. Buy a cheap backup vape in the meantime (even if it's something you wouldn't normally vape, like an ego style or AOI to get you through until you have the batteries you need or any other internal battery mod you may or may not have laying around. What I'm saying is, it doesn't have to be expensive, and you can use higher nic liquid to get you through and etc.

Best of luck,

Anna

What is over squanking? I mean what's the problem if there is extra juice, as long as it doesn't leak?

My GBOX Squonker can't suck the last 0.5ml. Do you have this problem too?
If you oversaturate the wicks you will have juice leaking all down the sides of the mod. I did this once.

This is the first pair of coils I've built for a RDA. Any comments? I guess the wicks are too much. The resistance reads 0.16 ohm.

I see, so I really should be worried. Curious to know, what is the safe wattage range with two 8A batteries?

The math to figure that out is easy. Take the AMP rating and multiply by 3 and then multiply times the number of batteries.

So two 8 amp batteries would be 8 * 3 * 2 = 48 max watts. However that is what I call the "bleeding edge" max. Considering nothing man made is perfect and what a battery can do will decline with age, I personally reduce that max by 15%. So in this case take the 48 max and multiply by 0.85 to get 40.8 watts max usable wattage with those batteries. Really I would get better batteries.

Are you using a single, dual, or triple battery regulated mod? In the interests of keeping things simple:

-If you use a good quality 15 amp CDR battery like the Samsung 30Q or Sony VTC6, then you are good up to 45 watts per battery; 90 watts using two; 135 watts for three batteries.​

-If you use a good quality 20 amp CDR battery like the LG HG2 or Samsung 25R then you are good for 60 watts per battery. If using a 2-battery regulated mod, you're good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.

-If you use a single 25 amp CDR battery like the Sony VTC5A, then you are good for 75 watts per battery, 150 watts for two batteries, and 225 watts with three.

-If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with a pair of 30 amp CDR batteries you could safely do 180 watts.​

While technically correct, like I mentioned above I consider these "bleeding edge" numbers and suggest a minimum of a 10% reduction to be safe, or a 15% reduction to be safer. I use a 15% reduction myself.

Looks ok. Does it work? You'll get better each time you do this. Try to get the tails a bit more even probably but other than that, looks ok. Practice makes perfect, they say.

I vape at 36w with a 0.16 ohm coil and it drains 15.2 amp. From the formula P=RI^2 we can conclude that if I double the resistance, the current will decrease by a factor of sqrt2, which becomes 10.8 amp. Right?

I'm still searching shops for batteries.
On a regulated mod wattage determines the amp draw, the resistance doesn't factor in.

Are you saying that regulated mods violate the equation P=RI^2? I changed the resistance. At the same wattage, the current decreased exactly according to that equation. 36~0.49*8.89^2

Before, it was drawing 15 amp with 0.16 ohm. 36=0.16*15^2

The regulated mod shows Ampere at the coil, not Ampere draw from the battery.
For regulated mods, you calculate Amp draw by the Watts divided by the Voltage of the battery.

So with a full battery its Watts/4,2. With an almost empty battery its Watts/3,x (depending on the cut-off voltage of your mod. If you wanna be cautious, calculate with 3 Volts.

So its Watts/3. Divide again by the numbers of batteries your Mod has.

I have no idea what batteries you have at hand here, but being cheap in regards to batteries isnt really smart. Lots of battery vendors ship world wide. Just get some decent 15 to 25 Amp batteries from either LG, Samsung, Sony or Sanyo.

Wow! Ok where to begin? The Radar is a horrible RDA. If you use the Radar and want to get any sort of performance out of it then try this. The coils need to be centered in the RDA and pulled out as close to the edge as possible without hitting the side or the top cap. The coils need to be raised up so you can barely see the bottom of the coils through the airflow. The wick needs to be cut so they just barely touch the deck on either side of the coils. The airflow needs to be able to go all around the coils. As mentioned many times in this thread already you need to get good batteries. At .16 ohms you needs to run those coils at around 80 watts to get any performance from them.

I think my sweet spot is at 36w with my Kanthal coils (0.48 ohm) and having the airflow 80% closed.

It draws 4.5 amp from each battery. For now, I'm not willing to pay 40$ for batteries. Yes, that's this expensive here!

36(w)/3(v) = 12(a), 12/2 = 6. That's 6 amps per battery, not 4.5. Please, learn the maths. Learn how mods use their batteries, and learn the danger of abusing a battery. You don't seem to give them too much attention, but remember that batteries are the danger in vaping.

IMHO, surface area is overrated and only part of the overall picture. Fancy coils generally means increased physical mass, which means more voltage power is required to fire the coil. Ramp up time is increased with more coil mass: it will take longer to heat up the coil and longer for it to cool down. You'll also drain your batteries faster.

What you don't know about batteries and ratings can hurt you.

Bench Test Results: AWT 35A 3500mAh 18650...laughably overrated, only an 8A battery, do not buy

Those Chinese batteries are rewapped rejects with grossly exaggerated amp ratings. The Chinese battery manufacturers use a lower standard in declaring their cells specifications.

Choose your batteries from respectable manufacturers like Lg, Samsung, Sanyo, and Sony (Japanese and Korean origin).


On a regulated mod the coil resistance is essentially irrelevant. What dictates the amp draw on the battery is the wattage you set with the processor chip.

Are you using a single, dual, or triple battery regulated mod? In the interests of keeping things simple:

-If you use a good quality 15 amp CDR battery like the Samsung 30Q or Sony VTC6, then you are good up to 45 watts per battery; 90 watts using two; 135 watts for three batteries.​

-If you use a good quality 20 amp CDR battery like the LG HG2 or Samsung 25R then you are good for 60 watts per battery. If using a 2-battery regulated mod, you're good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.
