You're better off with LG HG2 18650, 3000 mah ecig.com has a great deal on them. I think it was $5.00 each.sorry i am a noob at this. n im hijacking someone elses thread but u ppl seem to know what ur talking about. another issue i have is batteries. i have 2 beeway 18650s 2600mAh. are these ok to use i have no idea what amps can be drawn from them and i cannot find any specs of the batteries anywhere. they aren't flat tops but they fit in the ijoy. they seem to work well and they are not getting warm or anything. anybody else had any experience with them
