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, LG, Panasonic, 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 protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition.
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 cell is identical in appearance to the CoilArt 40A 4000mAh and Basen 30A 4000mAh cells. It performs the same as the Basens I tested but better than the two CoilArt cells I tested.
This Avatar reached the boiling point of water when discharged at its 30A claimed rating. I am giving it an estimated current rating of 20A, the same as the Basen and CoilArt cells.
It delivered 3963mAh and 3997mAh of capacity at 0.5A. Since the capacity rating should be lower than what any cell deliver in testing I am giving it a rating of 3900mAh.
Two cells were donated for the purposes of testing by Anthony Vapes (overview for Anthony_Vapes). Thank you!

- DC Internal Resistance = 22.2mOhms (milliohms) average for the two cells.
- Total energy delivered down to 3.2V at 10A continuous = 11.8Wh (Watt-hours) average
- Total energy delivered down to 3.2V at 20A continuous = 6.7Wh (Watt-hours) average
