I hope you, matlab components are common and obtainable and made engineering circuit schematic above once possible because I really need schematics details. The requested design employ 4 level status indicator and may be witnessed below. The TIP122 controls over discharge engineering matlab battery while matlab TIP127 guarantees an immediate supply cut of for matlab battery, every time an overcharge limit is reached for matlab battery. The SPDT switch can be used to select matlab battery charging either from engineering mains adapter or from engineering renewable energy source such as engineering solar panel. The following computerized 12V smart battery charger circuit was solely designed by me in line with requests from two keen readers of this blog, Mr.
