ZB2L3 battery capacity tester. It is used to measure the capacity of 1.2-12V batteries, particularly lithium-ion 18650 types. Here's some helpful information:
It discharges the battery at a constant current and displays the capacity on a 4-digit display.
It can measure up to 9999Ah, switching the decimal point for larger values.
The device has a micro USB interface for power and uses 5W ceramic resistors for discharging.
It supports a maximum current of 3.500A and has an error margin of 1% for voltage and 1.2% for current measurements.
It is compact and portable, suitable for testing various battery types.
It is designed for single-function use, controlling the load to obtain real-time integrated discharge capacity results.
The device can automatically identify and set the appropriate battery termination voltage
