These tests below 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” 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 physically and electrically protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition. Use of any of these batteries is AT YOUR OWN RISK.
Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.
If the battery has only one current rating number, or if it only says "max", then I have to assume the battery is rated at that current level for any type of discharge, including continuous.
Bottom Line
This cells looks and performs identically to the good performing Molicel INR20700A.
Xtar rates this cell at 30A continuous and 35A “max pulse discharge”. While both ratings are spelled out on the wrap in tiny text a different larger “35A” is much more clearly seen on another part of the wrap. I prefer to just see the continuous current rating shown this way to allow for direct comparison between cells.
The Molicel datasheet for the INR20700A only lists a 35A “maximum discharging current” rating with a max temperature cutoff of 85°C. This means you can use the INR20700A at up to 35A as long as the cell stays below 85°C. This should be easy to do as 85°C is frakkin’ hot. Just realize that a malfunctioning or autofiring device could easily exceed this temperature by a LOT if you are set up to vape at 35A.
I am giving this cell a 30A continuous current rating since that is as high as you can go while not exceeding the 85°C cutoff. This matches Xtar’s 30A continuous rating. To extend cell life, minimize voltage sag, and increase your safety margin, I recommend staying at 25A or under per cell. That’s about 75W.
The two cells I tested delivered 2932mAh and 2964mAh. This is decent consistency and meets Molicel’s 2800mAh minimum capacity rating for the INR20700A. It does not meet Xtar’s 3000mAh rating though. I am rating these Xtar’s at 2900mAh.
Two cells were donated for the purposes of testing by Xtar (XTAR,the best choice for fast charing). Thank you!

Performance Specs
DC Internal Resistance = 18.4mOhms (milliohms) average for the two cells.
Total energy delivered down to 3.2V at 10A continuous = 8.6Wh
Total energy delivered down to 3.2V at 20A continuous = 6.5Wh
Total energy delivered down to 3.2V at 30A continuous = 4.6Wh
