Single-cell lithium battery capacity test 1.4.1

Supports batteries from 0.8V to 5V, with voltage accuracy within 0.001V error and discharge current precisely controlled within 1mA, unaffected by ambient temperature, demonstrating high precision. This product has been calibrated with a 6.5-digit multimeter.
 
 
Below are experimental records:
Discharge current 1A, consistently maintained around 1A when heated with a hairdryer to approximately 50 degrees Celsius.
Next, regarding voltage accuracy, an adjustable power supply was used for visual comparison with a 6.5-digit high-precision multimeter to ensure the accuracy of the voltage and current readings. The
adjustable power supply was set to voltage 4.15V
to begin current testing, with a constant discharge current of 0.1A.
