I wrapped a super nano coil and put it into my IGO-L with a cotton cloud it came out to .5ohms. I have a Nemesis with Efest 18650 2000mah batteries. According to what I've seen these batteries are rated at 10 amps. My calculations have it at 7.4 to 8.4 amps depending on output voltages. So my main question, is this a "safe" combo or should I upgrade my batteries. Eventually I want to get some Sony 30amps but I have several perfectly good Efests laying around. Thanks!
