Upgraded Universal Replaceable BDC Bottom Dual Coil head: The Bottom Dual Coil head produce even bigger and better vapor production! Dual Coil = More and hotter Vapour (but shorter battery life)!! Do not continuously use, keep properly filled for optimal performance.
For Fit for: Aerotank, Aerotank Mini, Aerotank MEGA, Protank 3, Mini Protank 3, EVOD 2, T3D, EVOD Glass, but NOT interchangeable with (Mini) Protank 1 and (Mini)Protank-2. They can be easily replaced, just screw, no welding or solder.
Fit for:
Protank 3 Mini Protank 3 Aerotank Aerotank Mini Merotank MEGA EVOD 2 T3D EVOD Glass
If a clearomizer does not work well, you do not need to throw away the whole clearomizer, just replace a dual coil head, the clearomizer will work like a new one. Save Money!
The Bottom Dual Coil of our BDC coil head adopts high quality Nickel-chromium wire, can produce big vapor, no leak, no burnt smell.

Characteristics:
Normal resistance: Dual 3.6 ohm coils in parallel giving a total resistance of approximately 1.8 ohms (+/- 0.2);
Low reistance: Dual 2.8 ohm coils in parallel giving a total resistance of approximately 1.4 ohms (+/- 0.2)
Diameter: 10mm
Length: 30mm
How to change the BDC bottom dual coil head on Aerotank MEGA clearomizer:
1: Screw the Airflow Adjustemnt Base off the Aerotank MEGA Tank.
(Keep each parts of Aerotank MEGA Tank still tightly!)

2: Screw the Coil Head into the Airflow Adjustment Base.
(Make sure the Coil Head is snugged down hand tight).
