These tests below only note my personal ESTIMATED ratings for the batteries I tested 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 property damage, personal injury, or even death. They are not supposed to be used outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.
Testing batteries at their limits is dangerous and should never 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
Lishen is one of the large, established cell manufacturers in China (天津力神电池股份有限公司). This is a good performing cell, matching or beating the other Lishen 21700’s (LA, SA, SF) at 5A and 10A. It is about equal in performance to the Molicel M50A and BAK N21700CG- 50. The Samsung 50E2/50E3 beats this cell by a little. They’re all fairly close though at 5A-10A, you probably won’t see much of a performance difference between them. Stay below 4.8A if this cell gets more than a bit warm.
The cycle life rating in the datasheet is good but I have not tested it. In addition to the top vent this cell has a bottom vent which, in my opinion, should not be blocked or pressed against hard.
The two cells I tested delivered 4912mAh and 4938mAh. This is below the 5000mAh “typical” capacity rating but meets the 4900mAh “minimum” rating. The consistency is typical for cells I’ve seen from one of the larger China cell manufacturers.
Two cells were purchased for testing by me.

I want to work for the 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: Battery Mooch is creating battery and device tests | Patreon.
