WORD.because OpenUPS is too expensive
Looks like the board's got 6 pin molex, why not use that? You wouldn't want anything protruding at the back would you?
No the dc-ups board doesn't do that. OpenUPS by minibox.com does that but it's too expensive for me.but does your UPS board communicate with the PC at all, so that it knows it's being powered by a battery? I remember seeing boards capable of that somewhere (likely some tablet project here on the forums), but I can't see anything except power cabling on yours.
if you ever do get it to report over usb with that, will you upload the source code for it?No the dc-ups board doesn't do that. OpenUPS by minibox.com does that but it's too expensive for me.
My dc-ups does power path management, charge the battery when needed with proper cc-cv curve and does some minimal protection against under voltage and overcharging.
I'm planning to have the BMS do the battery reporting to the PC.
For this round I opted not to use one, because my earlier concept uses 5S which I bought a BMS for, and it doesn't support 6S.
Originally I was going for Tindie bms with atmega, that is open source, so I can write custom code to have it report stuff over usb.
Aliexpress got some rather expensive boards that can do reporting via uart and bluetooth, but don't think I'll go that route...
That's my plan, to stick with USB hid battery/ups class so that I don't need to write custom libusb driver/software for it.if you could get the USB HID Power Device stuff working I'm sure there might even be a market for it (if it were cheaper and less specialised than the OpenUPS I suppose).
