Bench Test Results: EVE 33V - 10A 3200mAh 18650…good performer, about same as Sanyo NCR18650GA

Test Report Summary: 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.

I want to work for the community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability, battery and charger testing and news, and a say in what I test, then please consider becoming a patron and supporting my testing efforts: Battery Mooch is creating battery and device tests | Patreon.

These tests only note my personal ESTIMATED ratings for these batteries 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.

Any rating in my ratings tables can change at any time as different grade cells appear on the market, we get swamped with fakes, or new information becomes available to me. Please, never assume that the ratings in the tables are permanent and will never change! Always download the latest version before considering any cell purchase.

This is excellent information, thank you! These kinds of cell alternatives are very helpful, and I’m genuinely appreciative of these tests.

I’ve used the Sanyo GA cells and Molicel M35A in a couple of boards, and I’m always trying to be prepared for possible future repairs or replacements in the event of some kind of pack failure.

Currently, stocking a case of every cell in anticipation isn’t sustainable, so knowing that alternatives exist that are relatively comparable is very nice.

Thanks sir.
