Protank and all BCC are pressure systems. These require enough draw to pull e-liquid into the wicks. Light draws may simply vaporize what little liquid is on the wick. Next Vape = dry
Think of it like using a straw in a fashion. Suck light and short and the liquid falls back never reaching your mouth. suck to hard and you may choke on the in rush from the straw.

The actual action in a BCC is Venturi draw - as air passes the wick negative pressure is created. This draws liquid to the wick.
When Draw stops, air rushes back into the tube and is drawn into the tank replacing e-liquid now in the wick.

There are many individual issues with the Use of BCC tanks all have solutions and very few are from improper engineering.
Les single biggest problem is figuring out what any particular individual may need to so to correct their particular issue.

If e-liquid is thin 70/30, the Protanks should work, even chain vaping.

Thanks very much for your comments.

I have thought maybe my vaping technique is not right?

Also - how tight we should screw the tank together? I seem to get better wicking/bubbles when I don't screw it too tight. Or we shouldn't see bubbles at all?

Bubbles should only come from Negative pressure drawing air through the Wick into the tank.
If the base is left loose, air can pass the seal at the coil head from the mouth piece. However, this usually creates flooding, not dry wicking.
With everything properly snug, You should be able to cup the tank in your hand(sealing base) Take a draw, release grip and see a bubble or 2 rise into the tank.

5 volts is way to high. On a 2.6 ohm coil that translates to 9.6 watts--way to high for those coil/wick setups. You need to LOWER your voltage not increase. I find the sweet spot for my Evods to be at 7.5 watts for taste and vapor production. On a 2.6 ohm you would need about 4.4 volts and a 1.8 ohm only 3.7 volts to achieve 7.5 watts.
Also, when you replace the coil/wick you need to wait about a half hour for the wick to saturate before you vape.

I have the same problem with my protank2 .....the evods and mt3s I have down to a science recoiled to 1.5 and rewicked with organic cotton but I just can't get the same setup to work on protank. The only thing that made it a little better was bigscreen d's vertical microcoil (sorry no link) but it's in the modding forum here. I'd say get some wire and try that before you give up

Im in agreeance with this. i run the 2.5ohm heads and havent found any juice that doesnt get burnt tasting at 4.2 or higher volts. I run all my juices in the 3.8-4v range

I retired my protank 2 for many of the same reasons. Burnt taste at correct voltages, leaking and blown heads.

On a provari its a known issue that you can't tighten the pro tank 2 down all the way and get good airflow. This may be causing the burnt juices. Went back to my original protank with a Rsst on order.

I'm in agreement with the other posters, 2.6ohm coils should give you good taste around 4.2-4.4 volts.

Huh. I'm new, too, and have a couple of protanks which I use with very boring, non-vv evods and 50-50 pg/vg homemade 16% nicotine juices. Mostly they work great for me. I've had your problem twice:

1. I held the button down too long by mistake, and the next few takes tasted burnt.
2. One particular juice tastes burnt on the 3rd-4th draw. It's a horrendous mixture of absinthe and peach which I wouldn't recommend as it tastes foul burnt or not. otoh I don't know why that particular mix should occasionally taste burnt. I tried it on both the protanks, and both do it, but only with that juice.

Ive had similar burnt taste issues with my PT2 on an MVP2. Basically I have to run it at 3.3v, the lowest it goes, and I cant do longer than 2-3 second pull or Ill get a burnt taste. Tried removing a wick, that gave gurgles sometimes, and still didnt completely remove the occasional burnt taste.

I tried flipping the little silicone seal over after reading this thread, so far so good. Ill give it a few hours and update with my results.

I am very happy with my Smok DCT setup, but I like the really light draw of the PT2, and the ease of changing flavors.

I just got the iclear 30 and the flavor IS amazing, but I get occasional gurgling with it.

When I get gurgles with the iclear30, I pull the drip tip off, run a qtip up into the drip tip and wipe up any juice sitting on the top of the rubber tip on top of the coil and go back to vaping. An airflow controller really helps as well. They sell them on Alot of websites for like $3.

Have you tried a high quality store-bought juice? There is a bit of a science to making e-liquid that vapes well. Ingredients bought at Walmart aren't necessarily the same as those a professional e-liquid lab uses.

I have plenty of store bought juice too, yes.

And the one I make - I use AG, PG and nicotine bought from Totally Wicked.

Newbie here as we'll. I'm not sure what it is but protank just doesn't want to work with certain batteries I had a vv ego battery smoked a 2.5 ohm coil on 4.0volts worked fine. Then I got I itastevv3 and tried wattage and I'm thinking it's a defected battery because anything over 7watts and I get that horrible Burnt taste but as soon as I switch bad to voltage it's fine!

On my protank 2 mini using 2.5 ohm coil. I have to turn the voltage down to 3.5-3.8. Anything more and all my juices taste burnt(anything from 100 vg to 50/50. I'm also using a vision spinner 1300mah.

Same here. With both my protank 2 and mini I am using 2.5 ohm coils at 3.7 v. Anything higher and it starts to taste burnt. But at 3.7 it is fantastic.
