ZY12PDN USB C 3S 12V Li Ion Battery Charger

[George R]

I would like to make a 3S 12V Li Ion battery charger using ZY12PDN USB C board. 

Can anyone advice please?

I would think you need a power supply  that is USB C compatible and supplies 15 volts like this one perhaps:

Plus a charger that has connections for balenced charging:

You can program the ZY12PDN to default to 15 volts instead of 5 volts.

I never found a ZY12PDN datasheet.

Does one need to use anything else (other than the battery controller) between the battery pack and ZY12PDN? because I connected them directly and my charger stopped working altogether. So I added a Boost converter in between the battery and ZY12PDN but ZY12PDN's light flashes, i.e. it charges for maybe 0.5 seconds and stops for 1 second or so.

My batter is this one. and I have the correct PD charger. and my boost converter is capable of supporting the needed current.

Can you provide a block diagram of your set up? You speak of "my boost converter" isn't the ZY12PDN a type of boost converter? From the USB_C five volts to various voltages?
