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.
Test Results
This is a good performing 26650 that is replacing Vapcell’s purple 20A 5000mAh and red 20A 5500mAh cells. It performs better than the 5000mAh cell but it’s not quite as good as the 5500mAh cell. I don’t think you’ll notice the difference though.
This cell is your best 26650 choice for up to about 15A/45W. Above that use any of the four cells that appear to rewrap the YDL 26650; Vapcell 32A 4200mAh, Hohm Grown 30.3A 4244mAh, Golisi 30A 4300mAh, or Aspire 20A 4300mAh.
The capacity for the two Vapcells I tested was 5319mAh and 5427mAh at 1060mA (0.2C) down to 2.5V. This is typical inconsistency for cells from the small to medium China manufacturers. I am rating these at 5300mAh.
Two cells were donated for the purposes of testing by Liion Wholesale (www.liionwholesale.com). Thank you!

***I have switched test jigs, resulting in slightly lower IR readings versus my previous setup. Add 1.6mOhms to this IR value in order to compare these cells to others tested previously.

- DC Internal Resistance = 21.0mOhms*** (milliohms) average for the two cells.
- Watt-hours (energy) delivered at 30W (10A) down to 3.2V = 15.7Wh
- Watt-hours (energy) delivered at 60W (20A) down to 3.2V = 9.3Wh
- 2-sec puff count at 30W (10A) = 942
- 2-sec puff count at 60W (20A) = 279
