High Rate 2S1P 18650 Lithium-ion Rechargeable Battery Pack 2500MAH for Lights and Devices
Battery Description
TINKO 7.4V 18650 battrey 2500mah battery pack is made by the 5C high rate cell, it max discharge current can up to 12.5A. It is widely used by customer for their device that requires high power such as the cleaning brush ect. Our lithium-ion battery and battery pack are widely used because of their advantageous features. Such as they have a high energy-to-weight ratio compares to other types of battery, so they can store more energy in a smaller, lighter package size. They also can endure hundreds to thousands of charge and discharge cycles, it means that their lifespan is also much longer. Their low self-discharge allowed them to retain charge for extended periods when you don't use it. With these features, lithium battery used in a variety of applications, from consumer electronics (smartphones, laptops) to electric vehicles. Their voltage and capacity also can be designed through different usage.
