So my mod isn't hitting as hard or getting as much smoke as it used to do you guys think it's the batteries or something else? I really havnt had the batteries for very long, since maybie last December, and oh I have the Segelei 100w plus, I have always been using the same Cotten and same volts(60) and same ohms, and I have 2 Samsung batteries so I'm not sure any help would be awesome thanks!
First thing I would do would be to clean the contacts in the battery compartment. Both positive and negative contacts.
I am assuming you bought the batteries as a pair and have kept them together, discharging and recharging as a pair as well right?
Are your batteries discharging at the same rate - when you remove them from the mod, do they read the same voltage?
If they are the Samsung 25R batteries, and they are genuine, I would suggest they should last more than a couple of months - unless you have put more than 300 charge cycles through them. I have a few sets of these same batteries since last September, and have had no degradation in performance at all. So based on that, I would suggest something else is going on here.
Oh and yeah, vapor not smoke
