Customized 2S2P 18650 Lithium-ion Battery Pack 7.4V for Digital Product

Battery Description

TINKO 7.4V 18650 2S2P battrey pack 4400mah with PCM board is a common model which is widely used bu customer for their electric product such as fans, toys and lights. The 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.
