* USB-C decoy board/port (20V) - ZYPDS, as mentioned above.
* Boost converter - I didn’t need 400W; I initially bought 250W but it had a defect and couldn’t wait for a new one from aliexpress hence me getting something local and thought I’d up the wattage a bit. Note that you can adjust both max current and voltage here (I intentionally capped it at ~1.5A being well aware of the USB-C PD boxes I have.
* Voltmeter/Ammeter combo - not really needed but it’s nice knowing how much juice I’m drawing/supplying. This is currently at 42V (all my boards are 10s right now); I’d adjust it when I finally upgrade to 12S. This is mainly for my folding board which only has 144WH because of size restrictions.
I was just following the lead in the posts earlier in this thread and in this video.
As for the others, 3D printed enclosure, cable (7A rating) with GX12 3pin on one end and barrel on the other.
