Customized 2S2P 18650 Lithium-ion Battery Pack 7.4V for Digital Product
Battery Description
This lithium battery pack is with 6 18650 battery cell, with the pack way 2S3P makes it's voltage 7.4V and high capacity to 7500mah. The battery cell is high rate kind, it allowed 3C discharge, very suit for the high power device.
TINKO lithium-ion batteries are widely used due to their advantageous features. They have a high energy-to-weight ratio, so they can store more energy in a smaller, lighter package compares to other. They also can work hundreds to thousands of charge and discharge cycles, making them durable for long-term use. Their low self-discharge allowed them to retain charge for extended periods when not in use. With these features the 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.
