EHPRO\/Bootes (not the EHPRO e-cig company) markets this cell to vapers but their web site clearly states it\u2019s not meant for use with e-cigarettes and that it is a serious misuse of the cell. We\u2019ve seen retail vendors do this, it\u2019s just a standard liability statement, but when the battery wrapping company does this with their own cells then is it done at our expense?<\/p>\n

What should we do when a company is willing to sell us something, pocket the profits, and then say not to use what we bought? If you didn\u2019t buy direct from their web site you\u2019d never know they say not to use with e-cigs. Just something to consider. This is different than what Sony and LG do as they do not market to vapers and they actively try to keep us from using their cells.<\/p>\n

Since EHPRO\/Bootes does not want anyone to use this cell with any vaping device I am giving it a Do Not Buy recommendation.<\/p>\n

On the wrap, in the tiniest lettering I\u2019ve ever seen on a cell, it says it\u2019s rated 35A continuous and 60A \u201cmax pulse discharge\u201d.<\/p>\n

Unfortunately, the 35A continuous rating is greatly exaggerated. This EHPRO\/Bootes cell appears and performs identically to the 20A-25A Sony VTC6A.<\/p>\n

I haven\u2019t seen the datasheet for the VTC6A to know Sony\u2019s ratings but EHPRO\/Bootes\u2019 claim of 35A is ridiculous. At that high a discharge current level this cell becomes hot enough to boil water. The VTC6A might have a temperature-limited rating that high but you must stop the discharge before the cell reaches 80\u00b0C. This means it cannot be a continuous current rating.<\/p>\n

The 60A EHPRO\/Bootes\u2019 \u201cpulse\u201d rating is useless.<\/p>\n

Any \u201cmax\u201d, \u201cpulse\u201d, or \u201cmax pulse\u201d rating is useless as we don\u2019t 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\u2019re not able to compare this cell\u2019s pulse rating to any other\u2019s.<\/p>\n

I am rating this EHPRO\/Bootes cell at 20A-25A and 3000mAh for any non-vaping use.<\/p>\n

Two cells were donated for the purposes of testing by EHPRO\/Bootes (http:\/\/www.ehpropower.com<\/a>). Thank you!<\/p>\n

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 \u201crewrapped\u201d batteries or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.<\/p>\n

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\u2019s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.<\/p>\n

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.<\/p>\n
