Be careful using LR gear on an ego battery. It tends to burn the battery out prematurely. If you want more info read this post.

I don't have much money to started building my own (cheap) mods. I built a variable voltage that actually is the one that works the best. However a LR cartomizer on a true 3.7 volt pv is almost as close. Also much easier & cheaper to built a small mod at 3.7 volts.
Here is a picture of a 900mah mod I just built last night for less than $5. The clear mod I made last week for about $8.
Those are nice! But I iz stoopid when it comes to building my own mods.
