Series voltage tester for power lithium battery is researched and developed independently by the Company. And it can test and monitor in real time the battery monomer voltage, and clearly display the data tested in form of histogram with 16-bit MAX1166 high-precision AD and 7-inch high-definition LCD, with obvious maximum/minimum voltage and differential pressure. Products enjoy smudge-proof, moisture-proof, anti-corrosion, anti-vibration features and resistance to high and low temperature (-25â - 85â), and can work under harsh environments therefore.
