Ω's law calcuator
ok
First things first, lets base things on facts
If someone is using lets just say AW IMR 18650 3.7v battery which at full charge with zero load reads 4.2 on its best day but on load reads 4v with a full charge on a .5Ω yes subΩ coil your discharge rate is 8 amps with standard 18650's (so long as the person in question is using a proper quality battery) being rated at a 10amp discharge rate. This is considered within the specifications of the batteries discharge capability. The average person takes a drag from between 5-20 seconds. Even chain vaping here's what happens....80+% of the batteries voltage rate will be discharged at an average rate of 3.6-3.7v putting your discharge rate down to 7-7.4 amps.
I run 30amp rated sony 18650's.
I run a 10amp fuse in case of hard shorts which has been tested though intentional hard shorts and pop's instantly....(BTW HARD SHORTS UNFUSED/UNPROTECTED ARE THE #1 CAUSE OF CONCERN OVER A BATTERY BLOWING UP, NOT VAPING)
so......moving on:
Can you blow up a battery if you sub Ω vape yes
Can you minimize the risk through knowledge and understanding of what your doing, much like anything in life? Yes
Can a lithium ion battery blow up randomly for no apparent reason? Yes
Can you get injured from things or get in an accident that would kill you 100 other ways each day you live? Yes
Like anything there are % based chances of crap going wrong. Every day any of us lives we have odds of dying but most don't focus or obsess over it simply because well......it makes no sense. Focus on the things you can control such as fact based research.
Mis-Information is worse than no information.
