Never used the Drop or the Big Baby Beast tank. If not mistaken, the SMOK tanks and coils require quite a bit of wattage (over 80 watts). I vape 30 watts with my Crown 1.
Crown 1 coils:
- 0.15 ohm Dual Ni200 Nickel Uwell Crown Sub-Ohm Coil - 400 to 600 Degrees Fahrenheit
- 0.25 ohm Dual Stainless Steel Uwell Crown Sub-Ohm Coil - 80 to 120W
- 0.5 ohm Dual Stainless Steel Uwell Crown Sub-Ohm Coil - 30 to 80W
- 1.2 ohm Single Stainless Steel Uwell Crown Coil - 10 to 30W
Not a fan of internal battery mods. The LiPo chemistry is not a "safer" battery chemistry; they are much more likely to go "KaBoom!" than IMR.
If your internal battery drains dead then you can't vape. If you used external batteries you can simply carry a spare charged battery with you and continue to vape.
And that Lipo is eventually going to die and then you have to replace the entire mod; with external battery mod you simply buy more $6 batteries and can continue to use the mod.
Charging IMR batteries in a dedicated charger is faster and safer than using an internal microUSB charger in an internal battery mod. A better choice in the long term.
Exotic coils vs simple coils? Simple all the way. KISS - keep it simple, stupid.
