1. The current a voltage V power W capacity ah and discharge time can be displayed; 2. Have a sound protection mechanism; 3. Automatic statistics of discharge capacity and discharge time; 4. Set maximum discharge Capacity (OAH) and maximum discharge time (OHP); (Realization of unattended aging experiments) 5. Intelligent temperature-controlled fan, when the power is greater than 10W or the temperature is greater than 40 ℃ fan start automatically; The use of rotary coding potentiometer, can accurately adjust the current, accurate to 0.01A, the current can be locked to prevent misoperation Data group function: You can choose whether to add up the capacity value and running time of the previous stage Has a powerful serial communication function.
