Alright sorry this might be a lengthy one but I posted something and got very good responses from the community so I figured I'd ask some more questions.
I took my 3 batteries out to charge them and noticed a rather large dark spot on the negative side (Samsung inr18650 30Q) There's 4 small creases or wrinkles that run along the battery(one runs from the positive to the dark spot on negative) so I put all the batteries in a case and am going to toss them and get some new ones. I've only charged them 5 times, always charging and discharging together. I got 2200 puffs out of them but I've only had them 3 weeks(batterys tends to last 3-4 days 2200puffs/21days=105puffs a day which would be about 420 puffs per charge, usually using in between 50-70W) is 105 puffs a day to much? Anybody else experience dark spots on batteries? I hate to think I'm doing something wrong somewhere and stressing the batteries...When I buy new batteries should I full charge them right away or discharge them first then full charge them? When using them should I run them down until my mod says low battery before charging or take them out earlier?(I never did let them get low enough for my mod to say low battery) Also I don't have a multimeter so I can't tell if I'm maybe overcharging them or over discharging them. So I'm going to buy 3 new batteries and a multimeter. So info and hypotheticals aside really my questions are, what can I do to keep my new batteries from doing this? Based on my info could I be making an error? Has anybody else had this problem? Another area I'm confused is in a 3 battery mod does that automatically mean I can use let's say as an example (3.0Vx3=9v 100W/9V=11.11Amps) I'm confused because somebody was telling me something about battery's running parallel or opposite and completely threw me off because if the equation is with say 6V (100W/6V=16.66) its past the safe discharge rate for my batteries. I can't figure it out, since there's 3 batteries, 2 run parallel to each other but there's also 2 that run opposite of each other. I can't seem to find anything on this other then info on 2 batteries which I can't seem to apply because it's both cases, 2 run parallel and 2 run opposite of each other. A little insight here would be great.
