So I am going to be getting an ipv 3 li here next paycheck and am wondering what type of 18650 batteries I should get. Before this I've always used mods with an internal battery.
Being that mod can range between 165w to 200w (with upgraded firmware), if you are going to be over 100watts all the time, LG HB6 or the Sony VTC4. Under 100watts Samsung 25R, Sony VTC4, LG HE2/HE4, Samsung 30Q
/edit
Also, remember with that mod, buy your batteries in pairs, mark them as a married pair to cherish each other until death do they part, never break the pairing, buy together, charge together, use together, never use one or the other singly or with another battery, and rotate them in what slot they are in the battery tray of your mod and charger, this way they stay the same number of charge and discharge cycles.
