Hello ian cummings，
Would you please kindly offer the product link or SKU number so that we can confirm which item it is?
No matter which converter it is, please set the output voltage and current for your battery firstly.

When actual load current decrease to 10% of preset current, “Charging” led will be off and “Fully” led is on.
For example, preset current is 1A, if actual output current is lower than 0.1 A, “Fully” led is on.

Hello Grant Yardley，
We are not sure exactly how it is. Did you connect USB-C PD board to converter output or input?
For charging battery, you can connect diode in series to converter output port, that can prevent backfeed current.

Are the serial parameters the same? For example, baud rate 9600, data bits 8, stop bits 1.

Hello Blake Ward，
Would you like to show us how it is by video?
When actual output current reaches the preset value, the CC indicator is on. Constant current mode is actually a current limit feature. Assume preset current is 2A, load will not draw more than 2A.
If you don’t want to limit load current, just increasse preset value.
Notice: For dead battery, charging current is high in the beginning, without current limit, it is easy to damage battery.
If you prefer constant voltage charging, please check if it is appropriate method for your battery.

Hello Blake Ward，
Could you please tell us wheter it is in constant current now?
Constant voltage and constant current can’t work in the meantime. When current regulator is enable, voltage regulator compoent is disable. Only one mode is enable each time. In general, we charge battery in constant current mode firstly, when battery voltage reaches preset charing voltage, it will enter constant voltage mode.
For any more questins, please let us know.

We are sorry we don’t have CAD file. Here is cut-out size for your reference.
