When choosing batteries for a regulated mod, pick a battery model which will provide the power necessary for the wattage setting you vape at.
Are you using a single, dual, or triple battery mod? In the interests of keeping things simple:
-If you use a good quality 15 amp CDR battery like the Samsung 30Q or Sony VTC6, then you are good up to 45 watts per battery; 90 watts using two; 135 watts for three batteries.
-If you use a good quality 20 amp CDR battery like the LG HG2 or Samsung 25R then you are good for 60 watts per battery. If using a 2-battery regulated mod, you're good for 120 watts as you have two batteries. If you are using a 3-battery mod, you're good for 180.
-If you use a single 25 amp CDR battery like the Sony VTC5A, then you are good for 75 watts per battery, 150 watts for two batteries, and 225 watts with three.
-If you use a single 30 amp CDR battery like the LG HB6 you are good up to 90 watts; with a pair of 30 amp CDR batteries you could safely do 180 watts.

Say you have a 75 watt regulated mod. Which battery should you use? If you typically vape at 30 watts, you don't need a 25 amp battery with only 2500 mah. A 15 amp battery with 3000 mah will have enough power for your 30 watts and last longer per charge because of the extra 500 mah capacity.
