Supercaps sound great in theory, but I’ve seen consumer electronics die from brownouts. If the DDPAI can handle brownouts properly and shuts off before the voltage gets critical, it could work well.I mean capacitors are 100% safe in heat ne whereas lithium batteries are "relatively safe"...
Why risk a 10mn car when there are safer alternatives.
I'll likely get a DDPAI capacitor one from Aliexpress (free shipping still available) if I can't find a capacitor one in SL
I almost went for a supercap to power an ESP32 myself, but I decided to keep things simple at the end.
Edit - no argument about safety. SC is definitely safer than Li-ion batteries.
