These tests below only note my personal opinion for the 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, EVE, Ampace, Reliance, Sinowatt, Lishen, BAK, or Sanyo can change at any time! This can be 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. Never use them outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous discharge rating (CDR), never let it get colder than 0°C or hotter than 60°C to help lower the risks and extend cell life, and keep the plastic wrap and top insulating ring in perfect condition. Never use a battery that is physically damaged in any way.
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
This is one of the best performing small round cells (18650/21700) we can buy. It’s one of the hardest hitters (highest voltage under load) at moderate to high power levels and is equal to the EVE 50PL 21700 at extreme current levels until it reaches its temp limit. The run time is, of course, shorter than the 4000mAh-5000mAh power 21700’s.

- The EVE 30PL performs a tiny bit better “on paper” than the LT 19660A (JP30) at 50A and lower but the 30PL is about 3gms lighter, 0.25mm shorter, and performs a touch better at extreme power levels. But the 30PL runs a touch hotter at 50A and lower.
- In my opinion you wouldn’t notice any difference between the 30PL and JP30 in actual use at up to about 50A. At above that the 30PL is a little better.
- I’ve done 40A and 100A continuous current “shootouts” directly comparing all the top power cells for my Patreon supporters but you can get a good idea of how this cell performs by looking at its discharge curves and E-Scores.
- The datasheet only has a 60A “maximum discharge” rating with a 75°C recommended temp limit and an 80°C max temp limit. EVE says you can run it at up to 60A but you must stop before the cell reaches 80°C.
- I estimate its true continuous current rating (down to 2.5V) to be about 45A.
- Its DC IR is about 6.5mOhms which is incredibly low and typical of the latest tabless cells.
- This cell has a circular weld line on the bottom where the anode of the cell’s “jellyroll” is connected to the inside bottom of the can. If you are spot-welding to this cell make sure to avoid welding on or next to this line. I did a full teardown of this cell, and all the other tabless cells, for my Patreon supporters.
- This cell has the CCC*** logo indicating compliance with that new testing standard so these could be full production cells (of unknown grade). Lets not get hung up on grades though, these are incredible cells no matter what grade they are.
