Battery Tester, 150W 25A/300W 30A Programmable DC Electronic Load Meter USB Tester Voltmeter Battery Capacity Internal Resistance Detection for Lithium Battery Testing(300W 30A)

Load can be set: constant current, constant voltage, constant power, constant resistance, power one-key detection, internal resistance detectionMeasurement parameters: voltage, current, capacity, power, electricity, test time, temperature.Six working modes: constant current work, constant voltage work, constant power work, constant resistance work, intelligent one-key internal resistance measurement, intelligent one-key power measurementMain Specifications:Two levels of current: 10mA, 1mA<;0.3%;10mA range can test large current. After testing, the 40.00A~0.02A current regulation control error is less than 0.3%;Timed aging discharge, low-voltage protection, over-power protection, over-temperature protection, anti-reverse connection protection and other functions.Intelligent speed-adjustable fan, the higher the temperature, the faster the speed, and the heat dissipation control is stable

• The load can be used on an independent computer, or it can be controlled by connecting to a computer via .
• Can draw discharge curves, transmit data, save data, etc. for various DC discharges, such as: lead-acid batteries, lithium iron phosphate, zinc-silver batteries, solar panels, polymer batteries, ternary batteries, power batteries
• It can perform discharge tests on various types of batteries, and can also perform aging tests on DC power supplies, chargers, mobile power supplies, and data lines.
• The four-wire system wiring is also compatible with the two-wire system, and the voltage measurement is not affected by the voltage drop of the wire, making the voltage measurement more accurate, and it is easy to test various data such as lithium battery/battery voltage/current capacity
• Long-term 600W load discharge aging test, intelligent temperature-controlled fan design, built-in large discharge tube with greater power and more reliability, test the overall capacity of the battery, service time, aging performance, etc.
