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 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 property damage, personal injury, or even death. They are not supposed to be used outside of a fully protected battery pack and you use them at your own risk. Never exceed the battery’s true continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.

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 is one of the large, established cell manufacturers in China (EVE). This is a good performing cell, a bit better than the LG MJ1 and about equal to the Sanyo NCR18650GA at 5A and almost as good at 10A. Performs a bit better than the EVE 25P, 26V, and 29V at 10A or lower. I recommend staying below 5A-7A to reduce the voltage sag and help to extend cell life.

I think the 33V could be a decent cell for low power vaping and large PEV packs, powerbanks, and other low power uses if you can find it for a lower price than cells from the big manufacturers.

This cell has a 60°C maximum surface temperature rating. Do not allow the cell to get hotter than this. This can easily happen in a battery pack or other setup where many cells are operating near each other.

The cycle life rating in the datasheet is decent but I have not tested it.

The two cells I tested delivered 3206mAh and 3236mAh. This is typical consistency for cells I’ve seen from the larger China cell manufacturers and meets the 33V’s 3200mAh Typical Capacity rating.

Two cells were purchased for testing by me.
