I'm really tempted by the TFV4, but mainly to use the RBA head in it, don't want to be tied down to buying pre-built coils.

Been using the subtank mini's with the RBA's for a while and been happy with them, but just fancy a change, I did win a triton and got the RTA head for that, but not impressed with that tank.

So how many have used the RBA head with the TFV4 and what was your impressions with it?
I'm using the rba but it leaks when I fill it then stops leaking just under 1/2 full. I haven't tried anything to correct the leaking other than breaking it down and putting it back together. The quad coil didn't leak. The only cause I can think of is wicking but I haven't had a chance to sit down to re-wick yet.

I don't really care for the quad coil head (needs too much power and too warm for my liking) but the flavor and vapor is nice on the rba. The pre-installed coil on the rba reads .7 ohms. I vaped 9mg on an iStick TC40W and the SX Mini M Class at a measly 24 watts and I'm impressed. The TFV4 setup with the rba is better than the Subtank Mini and the Triton IMO. I just have to stop the leaking.

BTW, it's leaking (pouring) from the side air flow until it gets to just under half full if anyone have any suggestions.

    I have same question as nailz. Also, everyone loves the quad coils and vapor production of this thing, would one get same results with their rba deck?

    Actually I don't want the same results, I have no desire to vape over 100 watts and go through 5 mils in a hour, if it wasn't for the RBA head, wouldn't look twice at this tank, as is to extreme with the stock coils for me.

    Isn't good that it leaks, that is one of the things I don't like about the triton, except that one is good till it gets half empty and then starts to leak, and as I've never had leaking problems with the subtank mini's with the RBA's, maybe I should keep looking.

    It's the first time I completely washed out the coil but it worked pretty well since I switched up juices. But yeah probably over kill. My brother initially did a double wrap (6 = 12) with 24 ga and it hit awesome the first three hits until he burnt the crap out of his mouth haha. Couldn't keep up. Now it's a 7 wrap 22 ga kanthal that wicks perfectly. No leaking

    I haven't used the Triton's rba but mine doesn't leak using factory coils. My Subtank Mini rba is a solid performer but the TFV4 preforms better minus the rba leaking problem.

    I thank you for your response but it wasn't the question I asked. I want to chuck clouds and don't mind going through 5 mls in an hour. I'm assuming I won't be able to achieve same results with an rba head as I would with their quad coil. Another reason I ordered this tank is I enjoy huge lung hits and find that my subtank mini is insufficient for that since I keep getting dry hits and having to change the wick like every day or two. Unless I'm using TC ofcourse but then I don't get the satisfying dense vape like I would with a dripper. Basically I'm looking for a dripper experience in a tank and I'm wondering if the tfv4 will provide that with their rba.

    Well as you quoted my post, I did give my response ;)

    But in answer to your question, not likely to get the same as the quad coils, as your limited to what you can build on the RBA head, probably can get a good low build, but not going to be able to a quad build on it though.

    It will put out more vapor than the Subtank Mini. I haven't had dry hits since I started using the rba late last night. I don't vape over 30 watts so I'm not a 100 watt user either.

    If you looked back a couple posts...you'd have your answer lol.

    You too.

    Weird, no leaks when I build the RBA deck. Check your wicks...

    Gonna try my vertical coil later today when I drain this tank.

    Yeah my wicks are way out and it never leaks so I'll second drift monkey. So I put some creme brûlée in my starre pro and brought it back to life... The hit is absolutely amazing. I think I'm gonna sell my tfv4... It's to hard of a hit and it sucks fluid. It does have a lot of features and is a great tank but just not for me. I'm not a 100 watt kinda guy. Burns my throat. You guys that can handle that are BA

    Just had a really good yet simple vape using Capella's Boston Cream flavour, mixed it at 15% 80vg, 20pg in the TFV4 tank and omg, it is just amazing. Next is a Pina Colada I have been experimenting with, this dam coil just brings flavour. Going to try the rba again today with some 22g and a thicker wick over the juice holes.. I'm loving this tank..Should be getting the Segelei 150w TC today too.. Happy vaping..

    I also picked up some Samsung 25r to test against these new 2015 VCT5's so I can finally see for myself how they perform under load.

    Just to add, when I go and see Bill today, (he knows his batteries, nice to have you back in town bro) he has some VCT4's too, time to put this to bed, for me anyway, it's bugging me.

    Very interesting day, the moto of the story is, research before you buy, I won't go into the technical details but...

    VCT5 2015 are 20A max, they are a good battery but then so are the Samsung 25r so your probably better off going with them as they are cheaper and basically do the same job.
    VCT4 are also 20A, which was a shock but its a myth they are 30A, they can just be pushed a little further near 30A..
    I'm guessing my stupid mod was playing up, thank god it's going tomorrow, my Segelei has been delayed because Vampire Vape were at vapefest so they didn't post it until today.
