AT520C Battery Internal Resistance Tester for Motive Power Battery Internal Resistance

AT520B AT520C are newly designed high voltage battery meter, which aims to measure voltage and internal resistance of battery with built-in current high voltage meter. It can test Not only 0.1mW-30W internal resistance of battery, but also max 800V battery voltage simultaneously at the same time, suitable for all kinds of high voltage battery test, such as multi-section series connection of high voltage, Li-battery and internal resistance
