EHPRO Pink-Black 2000mAh 35A 18650 Battery

Bench Test Results: EHPRO Pink-Black 2000mAh 35A 18650…a poor performing 20A battery

Bottom Line: This EHPRO doesn’t match any Samsung, Sony, LG, or Panasonic/Sanyo cell I have. I do not know if it is a China-manufactured cell.



The EHPRO Facebook page says it’s a 35A cell and the wrap has large letters that rate this cell at 35A “max”. The EHPRO web site does not have this cell on it.

EHPRO Pink-Black 2000mAh 35A on the wrap, in the tiniest lettering I’ve ever seen on a cell, it says it’s rated 20A continuous and 35A “max pulse discharge”. This pulse rating is useless as we don’t know the pulse length, time between pulses, and the criteria they used to set the rating (Temperature? Voltage sag? Cycle life? A combination of those or other things?). We’re not able to compare this cell’s pulse rating to any other’s.

Why is the lettering for the continuous rating so small but the 35A “max” rating so large? Why is this only referred to as a 35A cell on their Facebook page? Things that make you go hmm…

This is a poor performing cell with a lot of voltage sag. The Samsung 20R, having the same 2000mAh capacity rating as this EHPRO, ran almost twice as long at 20A down to 3.2V. I am giving this EHPRO Pink-Black 2000mAh 35A cell an estimated rating of 20A and 2000mAh.

Watt-hour and internal resistance measurements were not done as this is a poor performing, overrated cell. The inexpensive Samsung 25R runs for more than twice as long at 20A, runs several degrees cooler, is widely available, and performs a lot better too.

These tests only note the estimated ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” batteries 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 personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.

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