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
EVE makes some great cells that are usually lower priced and this another one. It ties the Vapcell F38 for the longest running 18650 at about 7A (21W) or lower and costs less. For the best performance and long cell life stay below about 5A (15W).
At 10A (non-continuous) it still performs well but other cells like the Molicel P28A and 30B, Murata VTC6, Samsung 30Q(6), and Vapcell F38 (if the cell they wrap has not changed) are a slightly better choice.
Two cells delivered 3470mAh and 3474mAh which is fantastic consistency but is under the 3500mAh rating. Since I cannot have the lowest capacity cells in the batch I am rating them at 3400mAh.
Their DC internal resistances were 30.1mOhm and 30.0mOhm, also incredibly consistent.
The datasheet doesn’t have a current rating for these cells but shows a graph with a 3C discharge, which is 10.5A. But this cell reaches its 60°C temperature limit at about 8A so I am giving it an estimated 8A continuous current rating and 10.5A non-continuous, “temperature limited” rating. Do not let the cell get hotter than 60°C.
