The Kelvin connection helps cut lead resistance error for more reliable voltage and capacity readings. It handles test voltages from 2-200V DC and suits lithium battery packs, DC power adapters, bench supplies and USB outputs. A built-in lithium discharge monitor tracks real capacity during controlled discharge, so you can gauge battery health over time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy we picked it\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-wire accuracy\u003c\/strong\u003e - reduces lead resistance error for cleaner readings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour load modes\u003c\/strong\u003e - constant current, resistance, power and voltage cover many test scenarios.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePC and app logging\u003c\/strong\u003e - view live curves and log data to spot instability, voltage drop or capacity loss.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eGood to know\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePower limits step by voltage: up to 150W below 36V, 60W between 36-80V and 45W between 80-200V. Built-in overload, overcurrent and over-temperature protection help guard both the tester and connected gear. A color display shows key data. It connects over Bluetooth and PC cable to dedicated software (Windows 7\/10+ and Android 5.0+; iOS via the E_test app), using _BLE for mobile and _SPP for PC, with pairing passwords \"0000\" or \"1234\" where needed. The included DC12V 1A power supply is US standard with a US-to-EU adapter; other regions may need a local 12V 1A adapter. The box includes the DL24 tester, DC12V 1A supply, PC cable, temperature probe, red\/black crocodile clip leads and a US-to-EU adapter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon questions\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e What are the safe voltage and power ranges?\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e 2-200V DC, with up to 150W below 36V, 60W between 36-80V and 45W between 80-200V.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Which modes are available?\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Constant current (CC), constant resistance (CR), constant power (CP) and constant voltage (CV).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e What software is supported?\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Windows 7 and 10 or later, Android 5.0 or above, and iOS via the E_test app.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e How do I connect over Bluetooth?\u003cbr\u003e\u003cstrong\u003eA:\u003c\/strong\u003e In the app, pick the name ending in _BLE on mobile or _SPP on PC.
