Rechargeable Lithium-ion 18650 Battery Pack 14.8V 4400mah for Digital Product
Battery Description
This lithium ion battery pack is made up by 8pcs of 2200mah 18650 battery cell, with the pack way 4S2P makes it's voltage up to 7.4V and high capacity to 4400mah.
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, alarm devices, monitor devices ect.) to electric vehicles. Their voltage and capacity also can be designed through different usage.
