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
A decent all-around performer available at a good price with what seems to be a reasonable 20A continuous rating. It performs essentially the same as the K25 I tested 4-1/2 years ago but I do not know if it’s the same cell.
This cell performs a bit better than EVE 25P, Murata VTC5, and Sinowatt 25SP, about the same as the BAK N18650CNP and Samsung 25R(8), but not quite as good as LG HG2 and Molicel P26A.
Its 35A “pulse” rating results in a quick drop to about 3.2V. I’m recommending staying below 30A and never letting the cell go over 70°C.
This is definitely a good cell to consider if you don’t need the absolute last bit of high performance and cost is a priority.
Some other results and info…

Some other results and info…
- DC IR measured 17.5mOhms and 17.7mOhms for two cells. This is amazing consistency.
- Capacities were 2495mAh and 2511mAh. This is decent consistency and are essentially at the cell’s 2500mAh rating.
- The charge rating is unknown. I recommend staying at 1A or lower unless Vapcell says you can go higher.
