A battery monitoring system has an LED matrix displaying plural battery group conditions. The matrix has a column defining reference row of LED indicators each active LED, representing an adjacent voltage range. The reference row is responsive to an average battery voltage of plural battery groups. Aligned in columns with the reference row LED's are plural LED rows, each row representing an individual battery group. An active LED indicates an individual battery group voltage of the corresponding individual battery group. Analog multiplexing of scanned battery group voltages are sequentially applied to the matrix rows at a scan rate greater than the visual persistence of the LED's so that at …
