The code displayed is a short circuit fault. Please rule out whether there is really an output short circuit. Then you can choose to change to other modes, such as forced charging mode, and restart charging!

For 12V batteries, the LiPO4 mode battery charging voltage is 14.6V (±0.2V), the Lithium mode battery charging voltage is 12.6V (±0.2V), Lithium mode enters the professional mode and you can choose the charging voltage when the voltage is 12.6V (±0.2V) for 3 seconds. The voltage is 16.8V (±0.2V) at 4S. The corresponding voltage at 24V is twice that of 12V.

After setting, if the power is turned off and then on again, the setting mode before the power off will be maintained.

It will automatically stop charging when it is full.

You can change the charging mode while the charger is connected to the battery.
