Adjustable Discharge Modes Internal Resistance Tester Battery Detector Module Battery Maintenance

Label:Yes - Compact Size for DIY and Lab Use: -Convenient Usage & Parameter Memory: Equipped with two battery holders for 18650 flat batteries. The left slot works as power supply battery compartment with hardware charge control. The right slot is for charge, discharge and capacity testing. The two slots cannot run tests at the same time. The battery holders use compact structure to keep batteries fixed steadily during testing. -Multi-functional 18650 Battery Testing Module: It offers charge and discharge testing modes. The right battery holder supports up to 1A charging under program control, while the left holder supports up to 0.5A hardware-controlled charging. Discharge test records time, capacity and energy data. It supports 1~9 adjustable charge-discharge cycles and 11 levels of cutoff voltage settings to match different test needs. Three physical buttons help switch modes, adjust settings and start or stop tests. It supports auto power on, long press to power off. The system saves your setting parameters after power cut. It has auto mode to complete full charge and discharge cycles automatically, and shows completed status once the whole test finishes. This tester supports internal resistance and capacity measurement for 18650 flat-top batteries. It comes with Type-C port for DC5V power supply. It adopts DC two-wire method for internal resistance reading, with real-time display of voltage, current, power, accumulated capacity and energy data on 1.77-inch LCD screen. It supports switching between Chinese and English interface for flexible usage. The module measures 108x72x38mm(4.25x2.83x1.50in), easy to carry and place on workbench. It includes power resistors for discharge load. Suitable for battery screening, capacity verification and DIY electronic projects. Notice heat dissipation during charge and discharge process. -Charge & Discharge Testing Function: -Dual Battery Slot Design:
