Though Efest has overrated this cell a bit it is a good performer, beating the 10A Samsung 48G and 15A Sanyo NCR20700B for total vaping time at low power levels, under 7A\/20W. It appears to be a rewrap of the LG M50 cell.<\/p>\n

The two cells I tested delivered 4900mAh and 4957mAh at 1.0A (0.2C) down to 2.5V. Neither cell met its 5000mAh rating. Every cell should easily beat the capacity spec as it\u2019s just a minimum guaranteed value. It should not be the maximum you can expect if you\u2019re lucky.<\/p>\n

LG rates the M50 at 4849mAh minimum to 5014mAh typical though so this Efest still meets LG\u2019s specs.<\/p>\n

I am estimating this Efest\u2019s ratings to be 7.3A and 4900mAh.\u00a0<\/span><\/p>\n

I want to work for the vaping 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 and testing news and a say in what I test then please consider becoming a patron and supporting my testing efforts: https:\/\/www.patreon.com\/batterymooch<\/a><\/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 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.<\/p>\n
