I actually vape at 35w since i bought .5 ceramic coils....before i was at 15w using a 1.5 ohm. Do i want a high amp if i ever did want to vape at 50-60w? I see the batteries at lower than 10amp....is that for real low wattage?
Those batteries are primarily used for low current applications such as flashlights, portable radios, and laptops. They are not of much use for vaping applications.
None of the 18650 and larger batteries that we use for vaping were designed to be used for vaping. They were specifically designed to only be used in battery packs with a BMS (battery management system) for the auto and portable power tool industries.
small battery pack with BMS
As vapers, we learned to take advantage of these small but powerful batteries because they happened to best suite our needs as a compact stored energy source. However, when the manufacturers found out how we were using them they were quick to point out that their batteries were not designed to be used as a stand alone single battery energy source.
As consumers and vapers, we have to be aware of the risks involved and accept the responsibility of using these batteries as safely as possible. Part of that responsibility means
educating ourselves about battery specifications and choosing the right battery for our particular needs. Not all batteries are created equal. Every manufacturer and battery model has its own particular specification in
capacity (mAh) and
amp rating (maximum continuous discharge rate). We all have to learn how to determine which battery best suites the way we vape.

* Manufacturer's CDR is 15A. The Samsung 30Q datasheet (Section 7.9) mentions operation at 20A. Operation at that level can be done as long as we don’t let the battery get above 75°C, its maximum rated operating temperature. This holds true for the Sony VTC6 battery as well. These are not a high performance “power” cell, designed for high current. They are a high capacity “energy” cell designed for low to moderate power levels and long running time. At higher current levels the voltage sag and power loss in the cell are huge. Do not exceed 20A.
Are you using a single, dual, or triple battery regulated 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.
