Current :Discharge: 0.10-20.00A, the minimum step is 0.01A (automatic current limit when the power exceeds the limit)Charging: 0.10-5.00A, the minimum step is 0.01A (the maximum current depends on the power supply current)Mode :DSC-CC (Constant Current Discharge): Constant current discharge, used to test battery capacityDSC-CP (Constant Power): Constant discharge power for simulating constant power devicesCHG-CV (constant voltage charging): constant current constant voltage charging, support lithium battery and lead-acid batteryAutomatic charge and discharge: support automatic "charge-discharge-charge" mode, test battery capacityVoltage measurement:0.000-4.500V (low voltage), accurate to 0.003V, error ±0.5%4.50V-30.00V (high voltage), accurate to 0.01V, error ±0.5%Current measurement: 0.10-20.00A, accurate to 0.01A, error ±0.5%Capacity measurement:Within 10Ah, resolution 0.001Ah10Ah-100Ah, resolution 0.01AhAbove 100Ah, resolution 0.1Ah

• Battery tester with charge and discharge function. Suitable for lithium battery/lead-acid capacity test (charging 5A, discharging 20A, maximum power 85W)
• Supports separate charging, discharging and charging and discharging test, supports connecting to a computer and using online software to charge and recharge multiple times, and has more extended functions.
• Wiring mode: Four-wire detection, voltage measurement and current channel are connected separately to ensure measurement accuracy
• LCD display: voltage, current, capacity, time, power, electric energy and other test data.
• Computer connection: dedicated USB to TTL serial cable (not ordinary USB cable) computer control, drawing curves, calibrating measurement benchmarks, upgrading device firmware, cycling charge and discharge, etc.
