    What is Sub Ohm vaping?

    Sub-ohm simply means the resistance of the atomiser 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 in massive vapour production. A high-powered device paired with a sub-ohm tank is required for sub ohm vaping (a separate high-drain battery may also be required - e.g. the Samsung 25R 18650).

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

    High-VG (over 60% VG), low nicotine (6mg or lower) e-liquid is recommended when using sub-ohm devices.

    Good strong battery, perfect for the job.

    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.

    Easy to use and charge

    It's a battery, been using it for 3 days and it's still at about 60% charge.

    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!
