Hellvape, just recently have been banging out some pretty decent gear and this time I was fortunate enough to get my hands on their newest super series RDA, the Hellvape Seri RDA.

Hellvape Seri RDA header

This RDA is not for the faint of heart as it’s capable of running at 200W with 3 coils! Yes that’s right I did say 3 coils!

Hellvape Seri RDA 200

Hellvape is based in China and was established in 2016!

Many will know the company for their Dead Rabbit range of RDA/RTA’s the likes of the Dead Rabbit V2 RDAFat Rabbit RTA, Dead Rabbit V3 RDA and the Dead Rabbit R Tank.

What Can We Expect From the Seri RDA?

What I love about using RDA’s is the sheer quality of vapour and flavour production. Add in being able to use your own DIY coils – this makes the use of RDA/RTA’s a cost effective and no brainer!

I’m not an expert by any means with running series builds, so in this review I’ll try to explain things as simply as I can and to the best of my limited knowledge!

Hellvape Seri RDA mod liquid

The Seri has a triple deck that runs coils in series; the kit comes with 3 low ohm coils, a short circuit connector is included to allow you to run a dual series build.

Hellvape Seri RDA coil configs

The Hellvape Seri RDA is not your normal run of the mill RDA and in my mind it’s not suitable for those with limited coil building experience!

To take full advantage of the Seri RDA I recommend using a high power dual battery regulated device – one that is capable of delivering at least 12 volts, like the Geekvape Aegis X.

Although most high power devices are not equal and have a safety cut off at 9v! Even the Aegis X at the full 200W with x3 coils in the Seri will not give you a true 200W vape it’s more like around 180W. Which let’s be honest is too much for even the average user!

Hellvape have released the Seri RDA in 5 great colours.Hellvape Seri RDA design colours

This RDA was sent to me directly from Hellvape for the purpose of review!

And as always my thoughts and views are my own after an extensive testing period.

Design and Build Quality

As always I’m impressed with Hellvape with their high manufacturing quality and design. This RDA is made from quality Stainless Steel and topped off with a Delrin 810 mouth piece.

The Seri RDA comes in a card box. I was sent the Gunmetal version for this review!

Extras Included

3×0.2Ω Ni80 coils, 3 pieces of shoelace cotton, a coil cutting tool, Allen key, screw driver, a Short circuit connector along with a BF Squonk Pin, O-rings and spare post screws.

Hellvape Seri RDA – Overview

Measuring in at approximately 39mm tall and has a base diameter of 26mm the Seri comes with a black replaceable Delrin 810 mouthpiece.

The Seri will dismantle into 4 parts.

6 parts if you take into account of the 510 connection pin and BF squonk pin!

Hellvape Seri RDA – Component Parts

From the top, the black 810 Delrin mouthpiece has a 15mm bore tapering to around 10mm. It is fairly tall which helps to keep heat away from your mouth.

Hellvape Seri RDA drip tip

The cap consists of 2 parts which helps with further heat reduction, the outer airflow sleeve has a heat sink to help reduce even more heat and gives the RDA a decorative look!

A heavily laser engraved Seri logo is on the front of the sleeve!

Each side of the sleeve has 5 diagonal lined airflow vents.

Hellvape Seri RDA outer airflow slots

This sleeve sits and locks over the inner airflow cap by 2 fins.

The inner cap reminds me of a layered cake! (I must be hungry LOL).

Hellvape Seri RDA inner cap/barrel

It has an imbedded O-ring for firm seating of the mouthpiece and the top centre section has a slotted lock mechanism which locks together with the outer sleeve and enables you to turn the outer airflow!

Hellvape Seri RDA barrel lock

On each side of the cap/barrel are 13 honeycombed airflow holes.

The lower section of the cap/barrel slips over the build deck!

Inside the barrel it has a dome effect, for stray liquid to drip back down to the coils!

You will also see inside 2 fins that lock to the build deck.

Hellvape Seri RDA – Base/Build Deck

On the bottom of the base all the normal information has been printed, this RDA comes preinstalled with a gold plated 510 connection pin!

The connection threading has been turned well.

Looking at the sides of the deck you will see 2 O-rings for the barrel to slip over and 2 cut outs for the fins on the cap/barrel!

Its liquid well is a deep 6mm, so no worries about over dripping or squonking.

This RDA has a set of 6 posts that sit upon Peek insulators, the centre 2 posts are raised above the 2 outer posts.Hellvape Seri RDA deck

I am not surprised with the great design and high manufacturing quality of the Seri RDA, all the materials used in its construction are top notch!

How Does the Hellvape Seri RDA Perform?

It’s got to be said, this RDA is well outside my comfort zone! Not because this is a series topper (I normally vape my Noisy Cricket v2 in series at 4.5 to 5V with dual 0.6Ω coils, my regular day to day vape with a parallel build is between 35/65W with a restricted direct to lung style), my problem is the sheer power the Seri RDA seems to require!

I’m however always up for a challenge!

So today I will be using my Geekvape Aegis X, I will also be using the 3 Ni90 coils that came with the kit!Hellvape Seri RDA 120

I don’t have any decent low ohm coils to hand of a different material, so I will bear the consequences related to my nickel allergy!

The e-liquid I will be using is from E Juice Warehouse “Cherry Yog”.

How to prepare the Hellvape Seri RDA for use!

With a series build like this, the resistance of each coil will add up to the final ohms i.e. 3×0.2Ω, so should be around 0.6Ω.seri series deck

  • Make your coils in the normal way or use the ones that come with the kit
  • Pulse and strum the coils for a nice even glow.Hellvape Seri RDA hot coils
  • Load your cotton into the coils – comb trim and tuck the cotton into the deck.Hellvape Seri RDA cotton in place
  • Dampen the coils and cotton with liquid.Hellvape Seri RDA wet cotton coils

Dual Build

Use the included metal Short Circuit Connector for dual builds, insert it as you would a normal coil in the centre post as below.

Reassemble the Seri RDA, and enjoy!

Building the Seri RDA is extremely easy, Hellvape even include a coil cutting tool and recommend you cut your coil tails at 5mm.

Hellvape Seri RDA Wattage, Airflow and Flavour

I started out at 80W, wanting to bed the 3 coils in before pushing them more! I soon found that the RDA wanted its heat so I piled on the wattage to 100 and then 120W, the flavour was good and the vapour was quite thick and cloudy.

With the airflow wide open it was quite airy for me, although not turbulently so. I dialled the airflow back to about ¾ open, which seems to suit me fine!

Hellvape Seri RDA 100

Pushing the 3 coils to the full wattage of my Aegis X (200W) was an experience and well outside my personal comfort zone!

Of course at 200W and with the amount of vapour the Seri produces came the heat much more than I am used to! But then I very rarely vape at this high level of wattage anyway!

200W cloud from the Seri RDA

Yes alright I’ll admit it! I coughed like a banshee, my poor old micro lungs just couldn’t take the volume of vapour and heat produced!

Strangely though even at 200W I was impressed with the flavour production. While I couldn’t toot more than a quick press of my fire button, the flavour I did get was full on!

Hellvape Seri RDA with liquid

In the main I have been using this RDA with 2 coils at between 80 and 90W.

I will go on the record and say I get great flavour and decent clouds with the Seri RDA in this dual configuration, less heat makes a more enjoyable vape for me!

Hellvape Seri RDA toot 100


  • Good quality and design
  • Solid materials
  • Deep juice well
  • Extraordinary Cloud production
  • Fairly good flavour
  • Easy to build on
  • BF Squonk pin


I don’t have any concerns with this kit, apart from the heat it produces at 200W!

Final Review Verdict

This RDA in 3 coil mode can produce an extraordinary amount of vapour, albeit with good flavour! If I had to categorise the Seri RDA I would call it a competition RDA, maybe it could be something for those hot summer weekends when you need a bit of cloud coverage lol.

Would I recommend the Hellvape Seri RDA?

As I said at the beginning this RDA isn’t for the faint of heart, if you understand Ohms law and battery safety and are competent at building safely then I’d say “Yes” go for it!

If you are new to building coils I’d recommend taking a pass with this type of topper for a while and study Ohms law and battery safety!

Would I buy this RDA again due loss or damage?

While this is not my type of topper, I’m glad that Hellvape sent the Seri RDA to me to try – for it to function at its best the Seri needs power and lots of it!

So “No” I would not be seeking to replace this one!

Hi my name is Kevin, I started vaping back in 2009 mainly because my little boy at 3 years old was starting to copy the way daddy smoked a cigarette! Over the years I have gained a good amount of experience with different types of vaping hardware but I'm just a normal guy who enjoys sharing my experiences. This is why I started my Youtube vape review channel in 2014. To date the channel has had over 500,000 views. Being disabled, vaping has given me a gateway to meeting people from all different walks of life, many of those I would not have met under other circumstances. The way I look at my reviews is, if I can convince just one person to give up the stinky’s my job is done. I class myself as a tinkerer as I like to take things apart to see how they work and put them back together, yes that includes e-cigarette mods! One day I would like to be able to design my own mod. I am a dedicated father, and husband to my sweetheart of nearly 30 years! Family to me comes before anything else.
