i bought a brand new xcube 2 160W mod with the tfv4 tank(full kit)...i have used 2 different batteries on it ( not quality ones) one of them is a 18650 3.7 5800 mAh and the other was a 18650 4.2V 3200 mAh...i fixed the tank on the mod and filled it up with juice waited about 15 minutes for the juice to wet the cotton, since then i only got burnt hits it also smells bad and i have taken about 20 puffs till now at not more than 30W....why do i get burned hits? how can i fix this? where did i go wrong? do you think i have burned out the coil with the bad batteries i have? should i try the quadruple coil? should i change the juice?
Why do i get burnt hits everytime i fire my new smok xcube 2?

Moving to New Members. Simple solutions is for helping beginning users with getting started.
The wicking material must be fully saturated before you press the fire button, after the wicking material is burned / scorched it will always taste burnt until you replace the head / wicking material.
Next time drip drops of liquid on the wicking material from the top & wicking holes on the side of the head until the cotton is saturated. Then install in base, fill tank, take a few un powered primer puffs, then let it sit a few minutes.
The batteries didn't cause the problem, but, I would not use the batteries you mentioned at all.
It is always best to use two equal matched & married batteries in dual battery APV's/power devices.
Using mismatched batteries can be dangerous especially considering the 5800mah battery is a low amp and not an imr/hybrid safer chemistry battery.
You need at least 2 identical (preferably 4) high drain IMR/hybrid chemistry batteries with a sufficient CDR to handle the amp demands of the power ranges you intend to vape.

Like stated above pre juicing your coils before inserting them is very important... Especially with the tfv4 for coils they are very large.. I will put a half a mil on them before I insert them then fill the tank let it sit for about 15 minutes close off the air holes and then I take 5 to 10 primer puffs really hard till there's no more air bubbles exiting the juice holes then it should be good to go
Like @Topwater Elvis said these are not safe to use in a dual setup. In fact it is very dangerous.
Please make sure that you fully understand battery safety of Li-Ion Batteries. Start with this Thread: https://www.e-cigarette-forum.com/forum/threads/warning-rechargeable-batteries-for-apvs.129007/
and work your ways through all the links.
If in doubt, ask the members here.
and also check what "marrying batteries" means. This is very important when using a dual battery mod.
I'm 100% i primed the coil, as i mentioned i filled the tank and waited about 15 minutes then took a few puffs at 20W and it was nasty so nasty it tasted so bad i couldn't stop coughing( i didnt screw anything apart the tfv4 tank already has the wick installed so ....). are you saying that my coils are ruined? should i change the coils?
the tfv4 tank already has the wick installed from the factory...but what do you exactly mean by "putting" half a mil on the coils?
Filling the tank and waiting is not priming the head properly and that will burn the wicking material more often than not. After you get a nasty burnt hit nothing besides replacing the head will fix it.
Also the burnt taste can transfer to the remaining liquid in the tank, even if you properly prime & replace the head the left over liquid can be tainted with burnt taste.
Before installing head into base drip drops of liquid on the wicking material from the top & through the wicking holes on the side of the head until the cotton is saturated.
Then install in base, fill tank, take a few un powered primer puffs, then let it sit a few minutes.

okay i will try to do that and get back to you but do you think i will get burnt hits anyways because im using a thick juice ? Im using liQua which seems viscous.
What is the PG/VG ratio?
Many folks use high VG with those heads/tank.
The most important part of your thread is the batteries you're using, it is not safe to use mismatched batteries, especially the non high drain, non IMR/hybrid 5800mah.
I would not press the fire button one more time using the wrong chemistry mismatched batteries.

the ratio is not written on the box but on their website its written 70%PG+30%VG...i have no idea about the amount of nicotine tho. the thing is i live in Iraq i think its only type of juice available here....we dont have high-drain batteries too.
I think i was not very clear about how used the batteries i mentioned, i tried a pair of the 5800mah and a pair of the 3200mah i didnt on my mod i did not mix between them.
Your power device (xcube2) requires high drain IMR/hybrid safer chemistry batteries for safe operation and proper function.
Using unknown quality or low quality batteries can be dangerous, especially dangerous when using the wrong chemistry battery's.
Like venting a battery or two at the same time, ruining your device up to an explosion when things go wrong.
You really need to find a place that ships to your country and get the correct batteries.
70% PG is usually considered fairly thin juice, if it seems thick it may have some sort of thickening agent in it or probably a sweet goopy flavor.
Most folks use high % VG low nic like 6mg or 3mg juices in subohm tanks like yours.
High PG will be harsh, high nic will even be harsher, sweet juices tend to burn easier any combination maybe your unpleasant tastes problem.

FastTech are a company that deliver to Iraq and almost every country. I agree with Topwater Elvis, an unsafe pair of batteries means an unsafe vape. If money is not an issue you MUST upgrade. I wouldn't use your device frequently, if at all.
okay here is what happened, i put on the quad coil but before that i cleaned up the tank from the juice and then primed the coil as it should be primed(but unfortunately it was leaking juice in the bottom airflow because i added too much juice) , then i clicked up the wattage to 50 i got some dry hits but after few minutes it was all good the vapor was amazing without any burnt hits until the tank was about 35% full the vapor then the vapor production dropped so i cleared the tank from juice in the bottom airflow , i filled the tank up with another juice it was leaking again in the airflow and i got nothing more than burnt hits, when i was firing it there was this weird sound it was like the juice was boiling there, i got juice in my mouth too when i was inhaling...the wick and the coil look very saturated i don't understand why this is happening this is so frustrating....
NOTE : I added about 10 drops of distilled water tp both juice.
im completely aware of fasttech but it takes ages for them to ship to iraq...and yes money is a problem.
Yep using those batteries at that wattage may yield an explosion! Not just a burned flavor.
Again, 70PG / 30VG would be considered thin juice, adding 10 drops of distilled water made it even thinner causing the leaking & flooding (gurgling, bubbling, boiling sound & juice in mouth)
Most folks use high VG juices in subohm tanks 60%vg or more.
It is always best to start off a new head at a lower power & work your way up to prevent scorching/burning the wicking material and allow it to 'break in'.
The tank you're using is more for direct lung hits/inhales, trying to mouth to lung inhale can cause problems.
Do you have the airflow closed off / reduced or is it near wide open?
Make sure the o rings / seals in place & un damaged, the head should be tight into the base, the base, tank & top should be snug enough to prevent leaks between the pieces, not crank it down tight.
To clear the flood - drain tank, remove head from base, blow the excess juice out of the head, dry airflow chamber, center tube/chimney/air tube & drip tip. Install head fill tank.
You can also try turning it upside down where the liquid level is below the wicking holes and pulse the fire button a few times to burn off excess juice.
The batteries you use are the most important piece/part of your set up, I do not know of any 3200mah batteries that have a sufficient 'amp rate' to properly and safely power your device.
If the chip isn't receiving the amps it requires it can not function correctly, it wouldn't be able to supply the power consistently or accurately.
The 5800mah should not be used at all for any vaping purpose.
Not trying to be rude or sound unhelpful but,
There really isn't much more anyone can help you with using the wrong unsafe batteries, liquids that are too thin for the heads you're using & unknown nic level.
High nic juice + subohm = harsh hits, some may describe it as peppery burnt taste.
First & foremost you need the correct batteries for safe & consistent operation.

The very inadequate batteries may be causing the mod to malfunction which is causing the wick burning.
