High speed sample rate negative delta voltage and zero delta voltage auto-detect cut off circuit with MOSFET control for peak detection. Pulsation charge method to prevent overcharge and overheat, can charge 4 - 8 cells of 4.8V to 9.6V. 2 modes of Fast Charging and Slow Charging, and allows to change the charging current by the DIAL LOG.

Great mid level charger!
