12V 100W Electronic Load Discharge Digital Battery Capacity Tester Testing Module DC This electronic load can automatically change the speed with the high speed fan. Fine quality heat sink can serve a long time performance. It supports multiple protections of overheat, overpower, over-voltage, reserve polarity and power supply voltage abnormity. Features: A professional test module for detecting discharge battery capacity. High speed of the fan can change according to the heat sink temperature.  conservation of over-heating, overpower, over voltage, reserve polarity, and power supply voltage abnormity. Equipped with industrial large tooth heat sink, dust-resistant, which can run for a long time. Long-lasting construction for a long time performance.
