KLARUS 5000mAh 21700 Power Lithium-ion Battery 21GT-50

Klarus LiR 21700 5000mAh 15A 3.6V Rechargeable Battery The Klarus LiR 21700, with a real capacity of 5000mAh 15A 3.6V, is based on Li-ion technology. This LiR battery boasts a sufficient discharge current of 15A, making it ideal for high-current electrical devices such as LED flashlights where maximum performance is desired. Li-ion rechargeable batteries are known for their very high capacity, lack of memory effect, and no self-discharge. LiR batteries have a much lower internal resistance than regular 3.6V Li-ion batteries. The protective electronic circuit located at the positive terminal (+) serves as protection against overcharging, short circuits, and reverse polarity. The maximum charging time for a fully depleted battery is approximately 5.5 hours (using a charging current of 1A). What makes this battery superior to other rechargeable 21700 Li-ion batteries is that its core is also used in the production of batteries for Tesla electric vehicles. The fully metallic body of the battery is sturdy and durable. It meets RoHS and CE certifications. Klarus batteries guarantee quality.
