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 very good performing cell, essentially the same as the Samsung 53G(1), in run time and max temperature. The Samsung 50S performs a bit better and the Samsung 50GB a little worse. They’re all fairly close though and I’m not sure you’d see any differences in actual use but BAK might be available at a lower price.
Like the Samsung 53G(1), I recommend running this BAK 53E cell down near 5A (15W) or so to reduce voltage sag and prevent early cell aging. The datasheet gives this cell a 10.6A continuous current rating but mentions that this would reduce the life of the cell if it was always run at this level.
Some other results and info…

- DC IR measured 19.3mOhms and 19.5mOhms for two cells. This is amazing consistency.
- Capacities were 5401mAh and 5410mAh. This is also amazing consistency and it’s above the cell’s 5300mAh nominal rating.
- The standard charge rating is 2.65A and fast charging is only 5.3A. I recommend staying at 2A or lower for long cell life.
