My last test of the awesome 30T was a year ago with early samples so I wanted to retest them now that they are becoming more available.
The cells I just tested from Enercig and IMRBatteries (two cells from each) performed better than the 30T’s I tested earlier. I don’t know if this is because those earlier tests had lower grade cells or if Samsung tweaked the chemistry since then.
Right now this is the best performing cell available to us for higher power levels and unregulated/mech mod users. The 30T is a true 35A 3000mAh 21700 cell that hits harder than any other round battery we use. New cells are always coming out but the 30T is king right now.
I estimate this cell’s ratings at 35A continuous and 3000mAh.
For those who noticed that the average DC internal resistance of these tested 30T’s is 0.3mOhms higher than the average for Vapcell’s rewraps of the 30T please note that at 30A this only results in a 0.009V difference in how hard they hit. Nine one-thousandths of a volt. This difference is well within the typical cell-to-cell variation for internal resistance and could have easily been the other way around, with these 30T’s testing better than the Vapcell rewraps.
Two cells were purchased from IMRBatteries for the purpose of testing by me. Two cells were donated by Enercig (www.enercig.com). Thank you!

I want to work for the vaping community full time!

These tests only note the estimated ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” batteries or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.
Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.
Any rating in my ratings tables can change at any time as different grade cells appear on the market, we get swamped with fakes, or new information becomes available to me. Please, never assume that the ratings in the tables are permanent and will never change! Always download the latest version before considering any cell purchase.
