^{Setting problem :}
When setting, if a certain value cannot be set when it stops (when it cannot be adjusted up or down again), you can set another voltage value first, and then set this voltage value. Is this a problem of circuit and program failure?

Wiring problems：
Because it is to charge the battery, it is necessary to distinguish the positive and negative polarity, and do not rush to power on after connecting the wires. Check whether the wiring is correct. Then power on and use it. If there is any uncertainty or doubt in the wiring process, please use a multimeter to test the positive and negative polarity to ensure that it is correct. Do not use blind wiring.
