Description:
- QF250W5-S is a high current charge and discharge tester for batteries within 5V. Through parameter settings, it is possible to charge and discharge lithium batteries to test the performance of the operated lithium batteries. This model of lithium battery charging and discharging instrument can achieve lithium battery charging and discharging, customized charging and discharging, upper computer controlling lower computer charging and discharging, or customized charging and discharging operations.

Functions:
- Charging function: The instrument completes a charging function according to the set parameters
- Discharge function: The instrument completes a discharge function according to the set parameters
- Custom charge and discharge function: The custom charging and discharging function means that the instrument continuously works according to the preset working mode. The instrument has 10 custom working modes.
1. Constant current discharge - constant voltage charging
2. Constant power discharge - constant voltage charging
3. Constant current discharge - constant voltage charging
4. Constant voltage charge - constant current discharge
5. Constant voltage charging - constant current charging - constant voltage charging
6. Constant voltage charging - constant power discharge - constant voltage charging
7. Constant power discharge - constant voltage charging - constant power discharge
