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, 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, 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 a great performing 18650! At 10A/30W to 30A/90W it performs the same or better than any 18650 I’ve tested, equaling the Molicel P30B at 30A…which is incredible.
At 5A/15W the EVE 35V and Vapcell F38 are better performers. At 5A/15W it doesn’t quite match the Samsung 30Q and Murata VTC6 but it’s about the same as the LG MJ1, Molicel P28A, and Molicel P28B.
I have not tested the cycle life of this cell and do not know if it sacrifices that for better short-term performance.
Vapcell’s 30A continuous current rating is high since this cell reaches its max temperature spec of 75°C at about 25A. Its voltage also sags too much at 45A so I am giving it a non-continuous, temperature-limited rating of 40A. Never let it get hotter than 75°C and I strongly recommend staying under 60°C to prevent accelerated aging of the cell.
Two cells delivered 2922mAh and 2938mAh which is great consistency but that’s under the 3000mAh rating. Since I cannot have the lowest capacity cells in the batch I am rating them at 2900mAh. This means nothing for our real world use though since it performs so well (small voltage sag). Just another example of how the capacity spec shouldn’t be used on its own to choose longer running cells.
The DC internal resistances for the two cells were 10.8mOhm and 11.1mOhm, also very consistent. Both cells performed essentially identically.
