What battery do you use? 0.15 is worryingly low for me
sony 30A 2000Mah for 0.15
Lg 20A 3000 mah for 0.20
Check both out using ohms law. Both are at listed CDR.
The actual math for 0.15 ohm is 24.87A at 3.7V at 91W. Truth be told, using the batteries we recommend, would be fine on both the sony and lg batteries.
What a lot of people fail to recognize is that the CDR is not a detonation limit. The batteries do not blow up if you hit 31A on a 30A battery. CDR stands for constant discharge rate, or the amount of amps you can pull from a fully charged cell until it becomes fully depleted, without over heating. So lets say you get 1 hour of vape time on a 30A battery. You are not going to hold the fire button in for 60 minutes. You are going to press it for 2 to 6 seconds. Then stop. Now as we know, the longer you pull current from a battery, the warmer it gets, and the higher the current you pull, the faster it heats up. CDR mainly come into play when a mod is fired accidentally or the button sticks. This affects the amount of time you have to un-stick the button or stop the mod from firing before it reaches venting temperature. The lower the ohm build the higher the amp draw and the faster the cell heats.
Now all that being said, we always tell new users to stay within the batteries cdr limit, until they learn enough about building, ohms law, the internal chemistry of each of the cells we use, how fast or slow they heat under load, and what to do in case of venting. In other words, for each battery, you should know how long it takes to heat to 100C, how long you can press fire button for and how long a rest between puffs is enough to allow the cell to cool enough to stay below 100C (usually we stay under 70C as a safety net- being the point were we stop vaping because the battery is getting hot)
Just a side note... with the recommended batteries we use, the main cause of explosions is not actually the battery. It is improper ventilation in the mod. So if the battery vents, the gas has no place to go inside the mod and BOOM.. just like an egg in a microwave.
