One pair of genuine Samsung High drain Rechargeable flat top batteries in 18650 size. This battery kit from Battery Bro includes a safety and specification booklet with authenticity hologram. It also includes a green plastic 18650 splash-proof case and micro-fiber carrying pouch that can be used for cleaning contacts. Battery Bro inspects and tests every battery. Every battery case is tracked with a unique authenticity code. These genuine batteries are manufactured by Samsung SDI and are guaranteed to be Grade A cells.

These are the high quality, safer chemistry, high drain, unprotected batteries you need for ultimate performance of your high wattage devices. This is one of the best 18650 cells ever made. It handles high current loads well with a maximum continuous discharge of 20A and good capacity of 2500mAh. The INR chemistry adds nickel to IMR chemistry, making it a "hybrid" that combines the safety and low resistance of manganese and the high energy of nickel. The resulting battery chemistry gives you high capacity and a high discharge current that is very safe and stable.

You must have high drain capacity for operation at higher wattage and low ohms. Lesser batteries will not be capable of supplying proper voltage.

As these batteries have the holographic authentication, you may buy with assurance you will not be receiving any of the dangerous fake or Grade B batteries that flood the market.

Please use only in advanced devices with internal protection circuitry to ensure the battery is not overly discharged. Please fully charge before first use.
