The IT5100 series is engineered for testing the internal resistance and voltage of various battery types, including lithium-ion batteries for electric vehicles and other high-voltage battery packs. The tester features AC 4-terminal sensing, which eliminates the influence of test leads on accuracy and ensures high precision during resistance and voltage testing. With a measurement resolution down to 0.1 μΩ for resistance and 10 μV for voltage, the IT5100 series provides the precision needed for battery quality control in production environments.

The IT5100 series supports simultaneous testing of resistance and voltage, with a high measurement speed of 125 tests per second. This makes it an ideal choice for mass production testing of coin batteries, UPS systems, and large cell battery modules. The built-in comparator function helps in automatically sorting batteries based on their measured parameters, such as internal resistance and voltage.

For data management, the IT5100 series has USB and LAN interfaces for communication with external systems. It supports SCPI protocols for remote control, which allows for easy integration into automated testing setups. Additionally, external USB storage supports long-term data logging and statistical analysis of test results, making it easier to track performance over time.

The IT5100 series is available in multiple models, such as IT5101 and IT5102, with variations in voltage and current measurement ranges. The IT5102 model supports up to 16 channels per unit, and with master-slave configuration, the system can be expanded to up to 272 channels. This flexibility allows for large-scale testing of batteries across various applications, including electric vehicles, solar storage systems, and UPS testing.
