Samsung 25R 18650 Li ion battery with solder tags / tabs
The famous Samsung 25R 2500mAh High Discharge 18650 Flat Top battery with welded tags / tabs which has the performance to power most of the high drain devices. These lithium rechargeable batteries is probably one of the best lithium ion batteries available due to being able to store 2500 mAh capacity and provide a discharge of 20A! With 20A continuous discharge current, this battery is no pushover and will work well with most applications. This makes these batteries ideal for high drain application (see below).

Usage & Charging
!!!!! IMPORTANT!!!!!These are immensely powerful batteries, and extreme care should be taken using them. Only use with brand name, quality chargers (like LiitoKala, Nitecore, XTAR) and equipment! Unfortunately, we cannot replace batteries that are damaged by non-compliant chargers or equipment. There are so many chargers on the market, we cannot possibly keep track of which ones will work with these batteries. You will have to contact the charger manufacturer to ensure it can charge these batteries without damaging them. Please ensure you only use these (or any other Lithium Ion) batteries with proper Lithium-Ion chargers and equipment. Lithium-Ion batteries can easily be damaged by charging them with too high current or exceeding the maximum rated current discharge.
We are bound by the Office for Product Safety and Standards in the UK to advise that Samsung have not designed, manufactured, endorsed or otherwise approved these products for use by consumers. You are of course free to use this product in any way you deem fit, but we recommend you consider that we make the following statement in light of Samsung's position.
Samsung SDI Batteries are not designed, intended or manufactured for use in vaporiser kits, mechanical mods, or anything known as electronic cigarettes.
All our Samsung SDI cells are printed with WARNING! FIRE HAZARD, NOT FOR VAPE
Use at your own risk. We do NOT accept any responsibly for damage, injury or death caused by improper use of these batteries!
Do not overcharge! Ensure the charger voltage does not exceed the batteries stated full charge voltage.
Do not over-discharge! Ensure the equipment you use do not draw more current than the batteries “Maximum Continuous Discharge Current”.
Do not leave batteries discharged for a long period! Leaving Li-Ion batteries in a discharged state can incur irreversible damage – creating a loss in capacity and a loss in cycles.
Do not short circuit your batteries! NEVER short circuit a 18650 (or more other) batteries! Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your equipment, and even cause serious injury to you!
Do not let your batteries touch each other or other metallic items! Keeping your batteries loose, such as in your pockets, is a serious way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe.
Do not dispose any battery in a fire! There are dangerous chemicals in batteries. If you try to burn your batteries, they will release dangerous fumes and will probably explode. Always dispose your old batteries to a battery recycling centre.
