And a balance charge cable like this: https://www.aliexpress.com/item/1005002974324352.html (3S 4 wires)

16AWG wire for the XT60 output, and for the wires between battery terminals

Printed in PLA+ but PLA would work fine too (my printer had issues with the filament hence the different colours in the print!)
