Berri 2x Genuine 18650 2500mAh 20/35A IMR High Drain Flat Top Batteries for High Performance Mods - Free case.

I would recommend these batteries to anyone! If you use a vaping box mod like I do then you’ll know that finding a good quality battery is very important and these ones fit the bill excellently.The transaction itself was brilliant. The item arrived fast, well packaged and in perfect condition, I couldn’t have asked for more! Up to now, after using these batteries for a good while I haven’t really had a bad word to say about them! They charge at a reasonable pace and even with thorough use by myself, they tend to last for a very long time, usually around 2 days for myself. Obviously depending on the capacity you pick up, they may vary and ofcourse personal usage will also have a huge impact. I researched around a good while before deciding to try the efest batteries but they turned out to be the most recommended and here I am, doing the same! I’ve had no quality issues, no random drains, no explosions (eek!) and for the price here I’d definitely say pick one up!

You can tell these are not cheap 'danger' batteries you read so much about in the press. Well packaged and working a treat with my Kbox160. Well recommended to anyone who needs some juice for their e juice

After using the Efest 3000mah nickel batteries I decided to upgrade these 'new for 2016' lithium 3500mah. I now get a full day of vaping instead of 3/4 of a day, and these are apparently safer and less likely to overcharge. I also went for the Efest twin charger which charges these lithiums in less than two hours. A worthy upgrade for the price, and for peace of mind as far as over-charging is concerned.

Very good reliability. I have vape 2 or three times a day in 5 minute sessions over the past 4 weeks at 35W. A battery needs charging every five to six days roughly. However I'm happy with the reliability, it's memory and the case that it came in..... cool set of batteries...!

Very bad battery's , in a nut shell last around 2 hours in a 200w MOD vaping At 80w. Take around 6 hours to charge. Paid a premium but got burnt buy the £8 Samsung's at least it ain't so much of a shame when they run flat, it's more expected

Miles better than some of the 18650 batteries on the market today, made a big improvement to the brightness of my LED torch and lasts far far longer than the cheaper batteries I've had before, will only buy this type now. Top marks for these excellent batteries.

Came very quickly just what I needed good value for money and even got a handy case to keep them together

Great batteries, I ordered two lots (always need back up) but it never arrived with the protective case to put them in

What can I say - does the job!

Exploded while on charge

Very poor cell. High internal impedance causes big voltage drop even at low load. Much worse than LG HG2, even than Sony vtc5.

Nice looking batteries and seem to function well. Holding charge ok

Very good batteries last all day when fully charged and come in a handy case ...

Great quality fair price quick shipping what more can you say.

Measurably worse than any other battery I have ever bought. Purchased solely because of high capacity. Nothing like as good as rival products.

I did unfortunately give these a bad review it turned out to be a faulty mod which was discharging the batteries, apologies 3 months and are fine in a different mod 😊

Power hold not as good as Efest for same use.

Very good👍🏻
