    This thesis is about meeting and answering the needs of devices with batteries for battery testing and management. The goal of the battery test and management's is to use the full capacity of the device and to be able to see the need for changing the battery at the right time. The increase in the number of electric appliances and electric vehicles also led an increase in the need of batteries recently. That situation affects every aspect of the daily life and healthy performance of batteries became even more important in terms of environmental security, efficiency and so on. Engineers have developed several solutions and technologies for these problems. Open-Circuit Voltage Measurement Method, Coulomb Counting Model and Kalman Filters are some examples. On the other hand State of Charge method helps us to get information about the health of the battery, However, all applications for the problem so far have been quite huge, inaccessible and hard to use. Since the batteries became an important of daily life more than ever, these applications are needed to be accessible, economic, precise and user-friendly. The aim of the thesis is providing an affordable and user-friendly device by integrating mainly the Coulomb Counting Method with several others successfully. Using Raspberry in the device helps it to be accessible, economic, fast and adabtable to different interfaces. All the components that had been used in the device in this thesis have approximately from %1 to %5 error term and therefore quite precise about the estimations. Today, the cost and the complexity of Battery Test and Management systems led waste of millions of batteries through ineffective usages. That harms the environment and economyof the world. The device that had been developed in this thesis, provides accessible, affordable with its 80$ price and user-friendly solutions for battery testing and management problems.
