The request of energy expanding step by step at a disturbing rate because of the infringement of the human advancement. To take care of the additional heap demand individuals are discovering some different ways like sustainable power source assets with some battery stockpiles as back vitality stockpiling framework. To achieve this, we anticipated that would intentionally acquire exact data from the battery using a contraption which was adequately fiery to give correct and stable data, adequately minimal that it could be taken to any remote territory, and used to log data in a glint removable limit. This data can be later separated to think battery confine, imperativeness, SOC and discharge twist which are all measure of prosperity of battery, certifiable applications would be battery attempting in Electrical vehicles, batteries in remote locales, for instance, sun based power cross sections and batteries at examine goals, where customer can log the data using this advantageous battery prosperity checking device on a SD card and dismember using distinctive models later on. This structure uses stand-out customer input system where customer enters measure of present and cut-off voltage in a txt record in the Micro SD card. In this paper, the maker arranged and fabricated a flexible little scale controller based device which is prepared for recording battery parameters, for instance, voltage, current and time, can draw customer inputted relentless current from the battery till the battery accomplishes a customer portrayed cut-off voltage.
