A DIY 4s Battery Pack is specially maked for Makers & Hobbyist. Inbuilt 4s Smart BMS & XT30 Connecter for Better Performance. You can use it to power up your device. You can also use it to make a Electric Bicycle, Inverter, Power Bank, and many more.

It is equipped with a battery holder so that if you have a bad battery, you can easily remove it and put a new battery back in, that too without the help of any soldering iron or Spot Welder.

The battery pack must provide the energy requirements of your system, and the pack architecture will inform the design and implementation of the battery management system and the thermal management system.

Lithium-ion batteries (LIBs) feature high energy density, high discharge power, and long service life. These characteristics facilitated a remarkable advance in portable electronics technology and the spread of information technology devices throughout society.

Lithium-ion batteries have made significant progress since their commercial market introduction in the early 1990s. Currently, the major markets are the powering of small electronic appliances such as cellular phones, portable computers, or cameras. Furthermore, lithium-ion technology is rapidly gaining market share in the power tools market. Higher energy density at comparable high power density as compared to alkaline batteries is the main driver.

In most of the early designs, the negative electrode consisted of graphite, whereas the positive electrode was made from lithium cobalt oxide. However, a wide selection of positive and negative electrode materials is under investigation.

In addition to high energy and power density, lithium-ion batteries have shown high cycle life particularly when operated under shallow cycling conditions.

Recently, serious development effort has been devoted to lithium-ion batteries for vehicle traction as well as stationary applications. Promising results have been achieved in both applications. Currently, high-capacity lithium-ion batteries are available as prototypes only.

A widespread introduction of battery-powered vehicles in the future might open new business models for electric utilities using a pool of electric vehicles plugged to the electric grid as a buffer for load management.

At the present time, limited calendar life when stored under full charge conditions is one of the major obstacles for use of lithium-ion batteries in the power sector. In addition, safety is a main concern in the use of lithium-ion batteries. The introduction of inherently safe materials or battery designs will be a prerequisite for wide market introduction of high-energy lithium-ion batteries. The use of lithium-ion batteries for applications in energy storage for electric grids or electric vehicles is subject to current research work.
