Product Features: Built-in intelligent temperature-controlled fan switch design Reduces fan noise and extends fan life! High speed, powerful airflow Supports 180W continuous discharge, suitable for long-term discharge or factory frequency aging testing Timed constant current discharge aging function Compatible with four major connection APPs Compatible with four major discharge modes Product Introduction: DL24: 660g, Dimensions: 20X20X10CM DL24P: 820g, Dimensions: 20X20X14CM Test Voltage: 2~200V Operating Current: 0.2~20A DL24 Discharge Power: Voltage * Current < 150W DL24P Discharge Power: Voltage * Current < 180W Four Connection Methods: 1) Apple Mobile APP: For Apple phones, please search for "E_test" in the App Store, download and install it. Then click the Bluetooth APP icon to open the software, and then click the Bluetooth icon at the top of the software to select DL24-BLE to connect. This allows for remote wireless control and measurement functions via your mobile phone. You can view the discharge status and various data clearly on your phone, including voltage, current, and power curves, etc... (No separate Bluetooth pairing is required; simply select DL24 from the software's Bluetooth icon.) 2) Android Mobile APP: Scan the QR code on the back of the host to download the corresponding APP software. After installation, open the software, click the Bluetooth icon, and select DL24-BLE to successfully connect and use. (No separate Bluetooth pairing is required; simply select DL24 from the software's Bluetooth icon.) 3) Wired PC Connection APP: After powering on the host, connect it to the computer's USB port using the included data cable. Then install the CH340 serial port driver. Scan the QR code on the back of the host to download the corresponding APP software. After installation, open the software and select the newly installed serial port model to successfully connect and use. This installation method is also compatible with Bluetooth serial port devices! 4) Computer Bluetooth Wireless Connection APP: First, add the Bluetooth device "DL24-SPP" as a serial port device on your computer. Then, scan the QR code on the back of the host to download and save the corresponding APP software. The software can be opened directly without installation. Select the newly added Bluetooth serial port model to successfully connect and use the device. Connection method: First, turn off the load switch ("OFF"), measure the current battery open-circuit voltage, then turn on the load switch ("ON") using the setting button. At this point, you can read the internal resistance parameter of the battery. The internal resistance calculation formula is: (Open-circuit voltage - Load voltage) * Current = Battery internal resistance Package includes: Tester x1
