DTK 18650 Battery 3.7V 3000mAh Li-ion Rechargeable High Drain Batteries Flat Top < 4 Packs >

This is my second order for these batteries. After using and comparing them against the Samsung and efest brand batteries i find them almost twice as strong. These are great batteries for vaping and I will be replacing all my batteries with these as needed. Great price also.

These are high quality 18650 lithium ion cells manufactured in China. I run three of them in my 12 volt vape, they fit well and have excellent contact on the terminal pads. I would consider DTK cells to be higher quality than LG, Samsung or Panasonic as the positive electrode is spot welded in four places where the others have only three.The shrink wrap is nice and slick and tight which helps with inserting and removing.My order of four arrived with a 25% charge and after a full recharge they perform just as well as the name brands. I’m rating at a four star because at $5 each I feel is too high for a mass produced product that is in every household in some place or another.Note: these are flat top cells.

Size fits fine and is protected, but that'll be the only pros I'll give this product. I use it for my vape device and this is far from high drain batteries. Doesn't last long at all and after weeks of usage, it's safe to say these are generic category batteries with low quality. Buyers, you've been warned - you'll get what you pay for. Better off purchasing something with higher quality and a little higher on the price range. Might be great for other electronic components, but highly NOT recommended if planning to use it for your mod devices.

These do not last as long and do not apear to be the real deal. Reviewing ratings compared to fake reviews makes me believe these are fake. Be aware like I am learning from proffessionals misleading use to buy products bynresearching on the internet how fake reviews are made.

One charge last 3 days on a a 230-watt smok vape mod, and I vape a lot. Excellent!!

Used these in my vape mod

Honestly expect a bit better performance and staying power in my box mod for a battery claiming these stats. So I think my rating is more than fair.

Who knows how long the 2 that work will last?
