lowest ohms on ego battery

I probably would not push it past 1.4
but then again the only thing I ever use ego for anymore is an evod when outside once in a while

When I rebuild mine I try to keep it around 1.5 for the ego's. Not sure what the lowest you can safely go is but it's better to be on the safe side.
hello thanks for the replies i am not worried about the batteries just that they won't blow up in my face is my concern if i am risking that i won't do it. Not that worried about dead batteries because i have a backup in my mpv v2 but i do a very heavy job moving around a lot so at work i want to use my egos
If it's a regular ego, not below 1.5 ohms.
If it's a twist not below 2.ohms. Anything lower will hamper the performance on the twist.

An eGo twist has a current limit of 2.5 amps. The most is power obtained at a resistance of 4.8v/2.5 amps = 1.92 ohms.
Maximum power is then I*I*R= 2.5*2.5*1.92=12 watts
Any resistance below or above that that reduces power to the head, but it is not too severe.
At lower resistance use I*I*R . So 1.5 ohms would be 2.5*2.5*1.5= 9.375 watts
At higher resistance than 1.92 ohms it is not current limited so use E*E/R. So 2.5 ohms would be 4.8*4.8/2.5 =9.216 watts maximum.
If you have a battery with different current and voltage limits, just substitute that for the 2.5A and 4.8 volts above.
I don't think you asked about the eGo twist, but you asked about the standard eGo. It would probably do worse especially at high
resistance bacause the voltage is never higher than about 4.2 V, and as low as 3.3 V at the end of charge life.. But I don't know the current limit on a regular eGo battery. If it is a lot higher than 2.5 amps then lower resistance might be superior.

Just looked it up and at 1.4 ohm you will be slightly above the battery rating. Probably safe from it venting or blowing up but why even mess around. I would never recommend 1.2ohm though! That's asking for trouble!
I can't get anything to fire below 1.8
I would like to see an eGo push a 1.4 ohm coil.

Yes and at 3.7v the lowest you should be going is 1.5 ohms. 1.4 would bring you up to 2.6 amps.
I'm not doubting that some would do it- but none of mine will. I just built 2 evod heads last night and both are 1.6 but the joye or vision batts won't fire them. Just a blinky blinky and nothing. I wrapped a 1.7 and same thing. 1.8 fires no prob.
