Hello and welcome back! Today we'll be looking at Hellvape's new Seri rda which boasts a capable 200W vape in a tri-coil series configuration. I wouldn't really consider this a beginner rebuildable for those just getting into RBAs, but I also think it would be a great deck to learn a lot about coils and how they operate for those that are interested, beginner or not. For all the flavor chasers, cloud chasers, and vapers looking for exotic builds, this is a definite must. There are a few caveats and drawbacks to a deck like this, but I'd say it's well worth the cost. If you've ever wondered why in the world you'd ever need a mod that puts out 12V, the Seri RDA is why.
Before we get too far into things, I want thank Sue over at HealthCabin for sending out this RDA for the purpose of the review. As always, I will do my best to remain unbias and objective.
Let's dig in!
Kit includes:
This kit includes all the tools necessary to build the deck using all 3 coils, which is great.
I'm not entirely sure why they labeled the colors out of the order in which they're displayed, but I added some arrows to clear up any confusion. I received the Blue colorway and it's more of a deep blue than what's shown in the picture above. More photos will give you a better idea of its actual look down below.

- Assembly -
All 4 parts are machined impeccably and fit very nicely together. Tight enough tolerances to provide a solid assembly, and loose enough to not make AFC adjustments and disassembly difficult.
In contrast, 200W with a 0.6 Ohm deck capped at 12V (a boosted dual battery or greater mod) only draws a little over 18 Amps leaving a plethora of available batteries to be used. Dual 18650 mods can very easily and safely handle this tri-coil series deck - I've been exclusively using a Dovpo Topside Dual Squonk mod for this review and it's been quite a treat.
What this atomizer allows you to do is reach 200W by taking advantage of Voltage instead of Amps using higher resistances, assuming you have the right mod for the job.
Closer pictures of the deck will be shown further below where you can see the configuration of the positive and negative posts.
Another great feature of the Seri RDA is that you can choose to use dual coils instead of a triple coil setup. A short circuit connector (comes with the kit) can be inserted in place of the third, middle coil, which will help direct the airflow up and around each coil.

- 200W -
You may ask yourself why 200W is even impressive? I vape 200W all the time with my 0.15 Ohm atomizer. The truth is, for low Ohm coils you're creating an excessive amount of heat/stress on your batteries as it requires an extremely high amount of Amps to vape 200W with a 0.15 Ohm coil. Do you notice your mod getting hot, very quickly? The setup mentioned above would need 34-36A CDR batteries (depending on your mod's efficiency) to be considered "safe". The only batteries that are rated safely at 35A are Samsung's 21700 30T's, and they cap right on the cusp of that safety margin. If you're using a dual 18650 mod to achieve 200W with a low resistance atomizer - well, it's your face and fingers you're putting at risk.
In contrast, 200W with a 0.6 Ohm deck capped at 12V (a boosted dual battery or greater mod) only draws a little over 18 Amps leaving a plethora of available batteries to be used. Dual 18650 mods can very easily and safely handle this tri-coil series deck - I've been exclusively using a Dovpo Topside Dual Squonk mod for this review and it's been quite a treat.
What this atomizer allows you to do is reach 200W by taking advantage of Voltage instead of Amps using higher resistances, assuming you have the right mod for the job.
- How It Works -
A single positive post located on the left side of coil A funnels current through the negative posts in coil A (right post), then coil B, then coil C simulating a single long coil. Normally, multiple coil decks are done in parallel where the current is pulled through each coil simultaneously, and the resistance is divided by however many coils you have in parallel. In series, the resistance of each coil is added, allowing a higher total resistance which makes more use of Voltage over Amps.
Closer pictures of the deck will be shown further below where you can see the configuration of the positive and negative posts.
- Great for Squonking -
The squonk pin outlet is raised up off of the juice well floor allowing a small pool of juice to remain at the base of the deck. The advantage of this is so that you don't have to squonk or drip juice every 3-5 puffs. For a triple coil deck, you're surely going to be using quite a bit of juice, so this deep of a juice well and squonk pin positioning only makes sense. Be careful not to over-squonk/drip and be aware if you tip your device while vaping. Juice sitting in the juice well can easily make its way out of the airflow holes if there's enough there.
- The Airflow -
As I mentioned above, the machining of this RDA is near perfect. It's tight enough where there's no jiggling and you don't have to worry about the cap falling off (it's actually locked in with this RDA) or leaking, but loose enough to where AFC adjustments are a breeze. Unlock many atomizers that I've tested, the airflow is suburb in all settings and doesn't make anything close to a whistling sound, thanks to the honeycomb airflow design.
