Samsung INR 18650-25r 2500mAh Battery

When I purchased a Kanger topbox nano kit the website directed me to this battery. So I purchased it. I am currently unsure whether it is faulty or is not the correct battery. It is either one or the other. Both are possible. Either way I am unhappy with the product and/or the service I have received. Especially if the wrong battery was suggested by the website. Potentially damaged my box.

Samsung INR 18650-25r 2500mAh Battery

I ordered a couple of these batteries the other day and i have to say, they are really good! they last me over a day, considering that i use my vape constantly i think thats very good! iv tried a few different batteries before but these ones have lasted the longest, they do take a of couple hours to fully charge so i recommend having at least two so when one needs charging, you have the other one to use. Overall, there defiantly worth the money!

What is Sub Ohm vaping?

Sub ohm simply means the resistance of the atomizer coil is below 1.0 ohm. Sub ohm coils are generally larger and therefore can utilise more power and cover a greater area of wick - a combination which results is massive vapour production. A high-powered device paired is required for sub ohm vaping (a separate high-drain battery may be required - e.g. the Samsung 25R 18650).

"Direct-to-lung" is the suggested vaping style for sub ohm devices (as opposed to "mouth-to-lung" -  how a traditional cigarette would be smoked).
