hi ive been looking over the web to see what would be the lowest amperage, 18650 battery that can function at 60w in this regulated mod. but my search has fallen shor, so im here, as a soon to be new vapor i hope i can find a high MAH battery and enough amps to safly run it. since i have doubts about these efest claiming 30a 2100mah and even higher amps with more mah. i've been mainly looking at the battery's that vaporbeast.com cary's but im still sceptical about it thanks for any advice
