This cell performed well, both its continuous current and capacity ratings are accurate, and only the continuous current rating is on the wrap of the cell. I love seeing this and hope it’s a continuing trend for other companies too.
This QSO outperforms both the Sony VTC5A and the 5-leg top contact 20700’s, hitting harder and running for longer. This cell roughly matches the Sanyo NCR20700A at 10A but the Sanyo is still the better performer at high current levels. It appears to be the same cell used by Vapcell’s gold 30A 3100mAh 20700.
Both cells I tested delivered more than 3100mAh when discharged at 0.5A down to 2.5V. I am estimating this QSO’s ratings at 30A and 3100mAh.
Two cells were donated for the purposes of testing by Qiso (https://qiso.en.alibaba.com). Thank you!

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 the tables can change at any time as different grade cells appear on the market or we get swamped with fakes. Please, never assume that the ratings in the table are permanent and will never change! Always download the latest version before considering any cell purchase.
