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, LG, Panasonic, 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 protected battery pack. Never exceed the battery’s current rating and keep the plastic wrap and top insulating ring in perfect condition.
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.
Bottom Line
This is a great performing “power” cell for unregulated/mechanical devices. As of May 2018 it hits harder than any other 18650 except the Samsung 20S down to about 3.4V. Below that point the 24S’ greater capacity holds its voltage up for longer.
At 25A the Samsung 20S is the clear winner. In the 15A-20A range it is a close race between the 24S and the VTC5A/5D/6A. You’ll have to test them to see which performs better for the way you vape.
I have often seen the 24S referred to as a 30A cell but it operates several degrees-C hotter than the 30A-rated Samsung 20S. In my opinion, the temperature difference between the 20S and 24S indicates to me that the 24S has a lower rating.
Typically, when the capacity of a battery goes up the current rating goes down as both of those require more room in the cell to be increased. The 20S has the higher current rating but the 24S has the higher capacity.
I don’t have the datasheet yet to know Samsung’s ratings but I am estimating them to be 25A continuous and 2300mAh minimum and 2400mAh typical. If needed, these ratings will be adjusted once I see the datasheet.
