Thanks everyone. I feel safer now. Yes it works perfectly. And the battery used to be a protected efest 18350. I just removed the protection circuit. Thanks again guys!!
I pulled the protection circuit from a 18350 in my Vamo...for a few reasons
A. The Vamo has overcurrent protection built in..the protection ckt on the battery was interfering with the overcurrent protection on the Vamo...shutting it down if I turned the power up over 4 watts
B. Running "normal resistance coils" on my Vamo means even at 6-7 watts the current draw will not get near the "overcurrent" conditions of even a ICR batteries current limit (IMR chemistry allow for higher current before it 'splody 'splody)
Running a "sub ohm" coil on a "mechanical rig" with a ICR with removed protection just turned it into a "grenade waiting to happen"
A mechanical is just that mechanical...its a physical push button switch, it would be like a car with no throttle..just turn the key and wham engine starts and runs wide open until the key to turn it off is turned...sub ohm will more than likely exceed the internal current capacity of an ICR which means it will heat up, lowering resistance making more current making more heat...get it going too long too hot too fast...thermal runaway and the already sealed and pressurized Li Ion battery pressure build like a propane tank in a fire and BOOM..you get a vent...lets hope the vent is controlled and not go off like a grenade!
Always remember IMR batteries due to chemistry and construction are capable of pushing ALOT more current than ICR's...this is why they purpose build the ICR's with protection!
Lithium Ion Battery Chemistry
ICR (LiCoO2)
Chemical composition is lithium cobalt oxide
4.2 volt max charge, 3.7V nominal voltage
Not a safe chemistry, so should only be purchased with a protection circuit that guards against overcharging and over-discharging
Higher energy density, but lower charge and discharge rate
IMR (LiMn204)
Chemical composition is lithium manganese oxide
4.2V max charge, 3.7V nominal charge
Safer chemistry, so is not available with a protection circuit. But that means you must guard against overcharge and overdischarge themselves.
Slightly lower energy density than ICR, but can sustain much higher discharge and charge rates. Use these cells when an application calls for "high-drain" cells.
IFR (LiFePO4)
Chemical composition is lithium iron phosphate.
3.6V max charge, 3.2V nominal voltage
Safer chemistry, so is not available with a protection circuit. But that means the consumer must guard against overcharge and overdischarge themselves
Lower energy density than ICR, but can sustain higher discharge and charge rates.
Do the math with an online calculator..most ICR's can push around 2-4amps, IMR's can push 10-20's (depending on model/manufacturer)
These guys show that ICR protected being able of pushing 2.5A continuous (same battery just different wrapper

By plugging in 3.7vdc to 4.2vdc (normal range of Li Ion voltages) the LOWEST you could go in resistance without exceeding the 2.5A MAX current is 1.48Ω any lower and you elevate the risk of 'splody 'splody astronomically...what happens if you accidentally push and hold down the button?

On a mechanical with no sort of protection...run IMR...you have to manually check to ensure you don't over drain the batteries though!
