As far as I know this is a power management board for a wii portable and not a raspberry pi. The voltages are all designed for what the wii motherboard needs as well as the screen. As for the battery I really don’t have that much info but, I don’t think using 2 lipo battery’s would work because the charge amps been set for 1s2p 18650 specifically. Again maybe I’m missing something.Hey, so I've been looking to getting into portable builds recently, and I've been trying to do a lot of research and figuring out how I will accomplish my build. My main concern is the batteries, as I haven't done a project with them yet, but I'm eager to learn. I love this design, especially with all of the safety features in mind. I still have a few questions though:
1. This seems to be designed for the 18650 Li-ion batteries, but Li-Po batteries seem to be similar, and would fit my planned form factor better, so are they good to be used in this setup?
2. I know the circuit is designed with parallel 18650s in mind, would I need to have parallel Li-Po's? Or could I just do 1 Li-Po?
3. How much current will I have to work with? I'm thinking of doing a Pi CM4 board, and my screen draws about 0.6A max. The CM4 board should take a maximum of 1.4A, and with peripherals in mind, it'd maybe add 0.5A, so I'd be looking at maybe 2.5A? I've looked into the datasheets and see about 4A on that boost converter. I shouldn't need this, but is that theoretically the max? or is there other factors I need to consider for my maximum current?
Thanks in advance!
