SMOK RBA Decks for TFV8 Baby Beast and Big Baby Beast 

The legendary SMOK TFV line of performance tanks has taken the industry by storm. Capable of an unprecedented octuple-coil configuration, this marvelous device has received rave reviews by vapers around the world. Using the respective pre-made atomizer coils, all of the variations within the collection are able to manufacture staggering amounts of vapor, coupled with truly rich and intense flavor. This performance is what sets Smok tanks apart from others currently on the market.

However, for experienced vapers who enjoy building their own atomizer coils, SMOK engineered the TFV8 Baby Beast and Big Baby Beast so that it can be paired with a separate RBA head, thereby transforming this magnificent device into a high-performance rebuildable atomizer.

SMOK TFV8 Baby Beast & Big Baby RBA Head Features

The SMOK TFV8 Baby Beast RBA and Big Baby Beast RBA replacement coil head is fabricated with premium 304-grade stainless steel. Durable, solid, and highly resistant to corrosion, this austenite metal represents an exclusive combination of steel, nickel, chromium, and manganese. It is equipped with a velocity-style deck, making it exceptionally easy to build on. The large deck space allows you to assemble complex and intricate single and dual-coil configurations, including those made with Clapton wire.

NOTE:  The Big Baby RBA version includes the extended glass necessary to use with the Big Baby Tank. This glass is not compatible with the Baby Tank

Rebuildable atomizers (RDAs, RBA, RTAs) and their use pose certain risks that you should familiarize yourself with. All rebuildable atomizers are intended for advanced/expert users only, and not meant for beginner or intermediate vapers. You should have a minimum of 6 months experience with rebuildable atomizers prior to purchasing one for yourself and attempting to use it without the supervision of an expert. You must have intimate knowledge with using multimeters; be well versed with Ohms Law and how it relates to wattage and voltage; be well trained in building atomizer coils and how to properly configure them; and have a solid understanding of electronics in general.

Prior to purchasing and using any rebuildable atomizer, you must make sure that you fully understand the following:

  1. All rebuildable atomizer coils must first be tested prudently with a proper meter prior to it being used, as untested atomizer coils can be extremely dangerous.
  2. Coils that have been improperly configured or are otherwise faulty can blow your electronic device, which can result in serious injury to you and/or your property.
  3. Atomizer coils that have been newly constructed must be tested on a meter, then first used on an advanced personal vaporizer (APV) that has all of the appropriate safety features, including short-circuit protection. Once the atomizer coil has been tested and used on such a device, you can then cautiously use the coil on a mechanical MOD.
  4. Faulty or otherwise improperly configured rebuildable atomizer coils can damage electronic devices, which can result in bodily injury or harm.

By purchasing and using this product, you hereby consent to wholly taking full responsibility and sole liability for the purchase and use of this item. You further agree to hold harmless and indemnify Vapor Authority, its managers, executives, successors, shareholders, owners, employees, directors, and all affiliates from any and all liability for the usage of this product.

Arrived on time was the correct item, works great.

Little tight for wicking, but good!

Still have a few different builds to try but it's been holding up well, somewhat tedious to wick but it's doable with adequate light. I look forward to it lasting a while.

These work great and the Vapor Authority was a great place to buy from. Will buy from them again.

I build mine with 24g kanthal and haven’t had any problems with shorting or any other problems people are reporting. Ohms do drop when it’s time to rebuild other than that a very satisfied customer

Idk man..... It's iffy.

I am having the same problem that others are having. I got two of them and right out of the box, with the coils they have installed its constantly shorting and reading whacky ohms. So I made my own coils, dual (26+32)*2+32g SS staggered fused claptons at 4 wraps, 2.5mm and I couldn't get it to stop shorting and reading whacky ohms. After some googling I found a solution, just search tfv8 baby beast rba shorting problem. apparently it's Smoks poor design on this deck and parts of the deck are touching the base. So I followed the suggestion and grinded down the bottom and sides but it's still not perfect. It still shorts from time to time and reads whacky ohms but for the most part it's staying at 0.2ohms. Im probably just going to stick with my Mesh coils for this tank, they've served me well for years now. And I really like building on the Geekvape Creed rta, the tfv8 Cloud Beast, the Tfv12 Prince, and the Griffin 25 and Bravo RTA. I will be fine with these tanks for years to come.
Love my tfv8 baby beast but building your own coils, the flavor is just insane! Forget the top airflow "leak proof" tanks, the flavor isn't there. Go for bottom airflow as long as you wick it good you'll never have a leak.
I highly recommend getting into making your own coils!
