This is the third version of this battery. The first had a five top “leg” top contact, the second had four legs, and this one has five legs but with a small “tab” at the bottom of each cutout in the top contact.
While these cells delivered roughly the same amount of energy as the original five leg version at moderate to high current levels (and much more than the four leg version) it did so at a MUCH higher temperature so it must be given a much lower current rating.
There was a decent difference in performance between the two cells I tested, much more than that typically seen between cells from Samsung, Sony, etc. This makes me think these iJoy cells are manufactured in China. But I don’t know for sure.
While the two cells I tested might be able to be given a continuous current rating between 20A and 25A I am sure they are not the hottest running cells from their batch. This forces me to rate this cell at 20A.
The two cells I tested delivered more mAh than their rating, 3188mAh and 3176mAh at 600mA down to 2.5V. Because this cell has already changed twice I am not giving it a capacity rating above the 3000mAh rating on the wrap.
I am ESTIMATING this iJoy’s ratings to be 20A continuous and 3000mAh.
Two cells were donated for the purposes of testing by Dash Vapes (http://www.dashvapes.com). Thank you!
Five cells were purchased for the purposes of testing by me.

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.
