1. Are the big baby and baby family of coils compatible with each other?
Yes, the Big Baby (BBB) and the Baby Beast (BB) Coils are compatible with each other on coils. However, if you do the RBA, you will need a special glass. In fact you don't have to go out and specifically buy the kit that Baby Beast RBA comes in unless you have a BB. If you have BBB you can go here, order the RBA, and the specialized tank glass- even in the colors you want.
- BB/BBB TFV8 RBA-16: Smok TFV8 RBA-16 -TFV8-RBA-16 They make two versions of the RBA- this is far better than the original. Instead of grub screws, it uses clamps and has better wicking chambers. Also, allows for claptons.
- BB/BBB TFV8 RBA-Original Version: Smok TFV8 Baby RBA Head -TFV8-RBA-Original The original version has smaller wicking chambers, you're forced to smaller coils otherwise regular coils will catch on the metal housing and short out. The original version also had instances of the grub screws getting stripped.
- BB/BBB RBA Replacement Glass: TFV8 Big Baby RBA Replacement Glass -You will need a different glass as the RBA is bigger than stock coils.
2. Or are the Full Size TFV8 coils compatible with the big baby beast since both tanks have a 24.5mm diameter?
The BB/BBB stock coils are compatible with each other. I know the Cloud Beast and Cloud Beast King coils won't fit. I don't know about the coils from X-Baby.
3. What are all these coils made of? I'm assuming Kanthal or Nichrome?
They all use Kanthal wire for the heating elements. Why doesn't Smok mention any of this?
They do, you just have to search it down.
4. Where are the the TC coils for TI, SS and NI? Does Smok have any plans of releasing them?
For TC Mode, they pretty figure you're going to build your own on the RBA's.
Oh! I just thought of something about Kidney Puncher (The place that carries the RBA and Glass)- They have THE BEST Shipping Department- Like EVER! They specifically say they won't warranty glass that arrives broken if you only pay for First Class Mail and not US Postal Priority. Well, I did only pay for First Class Mail, and read that rule after the fact. Well, when my package arrived, the box was high quality shipping material, not flimsy cheap cardboard type. Inside the package, my glass was in a tiny zip-lock baggie, then it was sitting firmly in a molded styrofoam, then the entire package was packed with peanuts. They took great care to package it well and safe from breakage. I can't sing their prices enough! I HIGHLY recommend Kidney Puncher Vape Supplies!! FIVE STARS!!
