High-voltage tester is researched and developed independently by the Company, and mainly used for the capacity and life tests of power lithium battery pack of more than 100V. With its dual-channel energy feedback, interaction of human-computer interface, as well as smudge-proof, moisture-proof, anti-corrosion, anti-vibration features and resistance to high and low temperature, it can be applied to various environments therefore.Range for voltage measurement: 100-1,000V; maximum charge & discharge current: 30A
