Never guess the voltage of your RC batteries again with the ISDT Battery Checker.
The BC-8S has three voltage display screens. The first screen displays a voltage for each of the connected cells. The second screen contains more information in the form of a battery graphic that shows charge capacity in percentage, the lowest cell voltage and the total pack voltage. The third screen displays individual cell voltages as a bar graph as well as numerically and can also be used to monitor / measure the condition of a lipo pack by recording the deepest voltage sag on each of the cells during flight. That information is then presented visually in the bar graph and can provide early detection of a weak cell.
