Hi, have a few questions and hope that you guys can be of help.
The TMAX uses a 18650 10a with a protank usely.
Buddy of mine wants to know if he can use a 20a 18650 battery in the sigelei TMAX?
The tmax goes 3-6 volts, also can go up to 15watts.
10a panasonics is enough or go with LG H2 20a's?
He be using 28 gauge coils.

Thanks for your help.

Jim

Sigeli Tmax is a 15w device that has a 1.2 ohm minimum. Variable voltage can push it up to 6 volts. So, even if I were to use the highest voltage with the lowest ohm coil, it would be using at most 5 amps.

So, most batteries will work. I recommend the 10a panasonics. The panasonics last a LONG time, but, just keep in mind that I wouldn't use it for anything with higher specs. The only question, is if they'll fit... and that, I don't know. I don't know how forgiving the Tmax is with battery sizes.

Oh, forgot to mention... yes, he could use a higher amp rated battery with no problem. After the 10a rating or above, I'd be looking at the MaH (Milliamp hour) for how long the battery lasts, and find the rue rating.
