These tests below only note my personal 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, 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 cell can easily be confused with the M50LT but it doesn’t perform as well as the M50LT. The Samsung 50S, Samsung 50E2, Molicel M50A, and Tesla Model 3 ultra-high capacity cells also perform better.
This is not a crappy cell though! It’s still a decent performer, just not as good as the best ultra-high capacity cells. If you could find M50T’s at a low price they might be worth considering.
This cell has a 14.55A rating for up to 25°C but the rating drops to 7.275A above 25°C ambient temperature, up to a max 55°C. For many uses that makes this a 7.275A cell since it will be used in a small space or battery pack where the heat will be trapped. I recommend staying below 7A or so to minimize voltage sag and extend cell life.
The cells I tested delivered 4891mAh and 4894mAh. This is fantastic consistency but it’s below this cell’s rated capacity of 5014mAh. I’m rating them at 4900mAh since both cells are so close to that.
