These cells appear identical to the LG H30 samples I received earlier this year but they did not meet LG’s 3000mAh minimum capacity rating. The two cells I tested delivered 2946mAh and 2947mAh at 600mA (0.2C) down to 2.5V.
This cell is a decent performer but the Samsung 30T is a MUCH better choice at high current levels, delivering about 30% more energy down to 3.2V at 30A. The Samsung 40T will also outperform it at up to about 20A-25A.
I am ESTIMATING this Vapcell’s ratings to be 30A continuous and 2900mAh. LG lists a 35A “max” discharge rating for the H30 but I believe that to be a temperature limited rating. LG lists a max cell surface operating temperature of 75°C and the two cells I had reached 74°C and 75°C at 30A. The “fast discharge” rating in the datasheet is 30A.
Two cells were donated for the purposes of testing by 18650batterystore (http://www.18650batterystore.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.
