    Perfect.

    Used these in pocket sized TacLights & other designed e circuits. I've had very good luck with eFest batteries and they tend to give long service life (as compared to those pea green colored batts - blech). I use eFest batteries in electronics circuits; in series or parallel depending on V or I need, of up to a 4 battery bank as VPS, if needing other V, by using tapped voltage divider to power various sections of an e circuit. Fun schtuff.

    Efest is the spoof we have all been reading about!

    I have been a large purchaser of Efest batteries for over two years. Even after all I have read about Efest exaggerating their specs... Well, beware of "the purple battery" as now it has been proven to me that their specs are out of whack! I was not certain nor convinced in either direction on the controversy surrounding Efest batteries... Not until I needed them to put out 20 Amps... I bought these "latest and greatest" Efest batteries rated at 35 Amps & 3000 mAh. Now I am stuck with $50 of cells that will satisfy only my "old mods". As it turns out they WILL NOT fire the required 20 Amps to operate the newly released Evolv DNA 200. This is the latest chip to date and the one most are looking to acquire...

  • Research this one folks

    Efest has been changing up its cells on us and maybe trying to pull a fast one. Especially this cell. Turns out there are several different cells being used from different manufacturers. One of them is a poor 10amp MH1 cell. I will no longer buy or recommend Efest. Its not like they are making enough money already.

  • High quality batteries from a reliable company.

    I recieved my batteries today and a separate charger I purchased from the company and am very happy with the quality of the batteries and charger. I feel safe using them for my vape mod. They come in their own plastic case each separate and have a scratch off indicator for the serial number so you know their authentic and new. Thank you!

  • Excellent batteries, highly recommend!

    The batteries are great, but they did not come in the to pack case like it shows in the picture. They come in individual tubes. If I would’ve known that they came in individual tubes instead of the two pack, I wouldn’t have bought them, I wanted the to pack case. Didn’t get with the picture showed.

  • 18650 purple efest

    By far second favorite batteries I've invested in (first is vtc 4), the first version was decent and these just blow me away, high mph, really reliable, non tear too! Bought 2 just to see how I liked them and I'm definitely buying 4 more tomorrow!

  • Works great.

    The reason for the 4 stars and not the 5 stars is. Not a whole lot of difference between the 2800mAh and these 3000mAh. Which isn't a bad thing, they still work great and last for quite some time in my mod. I will be buying more, unless there are some a little bigger in mAh's for a great price.
