This is a good performing cell that appears to use the same Yong De Li New Energy Company YDL 26650D cell that other companies also wrap. It appears identical to, and performs essentially the same as, the YDL cell.
The capacity for the two Golisi cells I tested was 4194mAh and 4202mAh at 860mA (0.2C) down to 2.5V. This is good consistency for a China manufactured cell and just barely meets the 4200mAh minimum rating that YDL gives their cell. Considering the differences in the equipment used by everyone I am not going to worry about the one cell testing at 4194mAh. These cells do not meet Golisi’s 4300mAh capacity rating though. I am rating this cell at 4200mAh.
The “typical” capacity rating from YDL for this cell is 4300mAh so I guess that is why the rewrappers of this cell use that number but, like we saw with Aspire, that number is too high.
Golisi gives this cell a 40A “max” rating but that results in a lot of voltage sag, increases your risk, and shortens the overall life of the cell. There is also no definition of what “max” is so it is a useless rating. I recommend staying below 30A and I am giving this cell a 30A rating.
Two cells were purchased for testing by me.

I want to work for the vaping community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability, battery and charger testing and news, and a say in what I test, then please consider becoming a patron and supporting my testing efforts: https://www.patreon.com/batterymooch.
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, Murata, LG, Panasonic, Molicel, 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.
