4-Channel Lithium Battery Capacity Internal Resistance Tester Measuring Module

【Four-channel capacity and internal resistance measurement】: This tester supports four channels for measuring battery capacity and internal resistance, allowing separate setup and operation without interference. 【Accurate internal resistance testing】: The direct current two-wire method is employed to accurately measure the internal resistance of the battery, providing highly precise results when the battery is fully charged. 【Flexible charging and discharging modes】: This module supports separate charging and discharging, and the automatic mode allows for up to 9 charging and discharging cycles. It also features automatic cutoff charging and automatic stop when discharge conditions are met, with adjustable cycle settings. 【Comprehensive real-time data display】: The digital display provides real-time information including voltage, current, cumulative capacity, cumulative energy, battery internal resistance, cumulative runtime (hours:minutes:seconds), cycle times, stop discharge low voltage, working mode menu, and status/channel indications. 【Convenient battery holder and heat dissipation】: The compact 18 650 battery holder ensures easy and reliable battery measurement. The module also includes an active fan for efficient heat dissipation and incorporates overheating protections.
