Haha in that sense, yeah that’s not a bad option.
I think some power delivery negotiation receiver boards can still accept lower voltage as well

140w is tons for what we are doing here. I still charge some of my boards at 0.1C just to keep the batteries happy, so this will certainly be nice. Fast charging ofc wont be done over USB-C

trend is that manufacturers are slowly moving to GaN, and with phone manufactures ditching chargers (ie you have to buy them separately) we will be seeing a lot more of them a lot sooner than i first thought
ps, i just want to take the opportunity to thank you for all your hard work throughout the years

Hm, I mean this is an intresting project, I’d even be keen to try and take a stab at designing it.
But considering how the IC shortage is now, I’d say we realistically have to wait until supply of ICs gets better.

Hmm I guess I want a USB C PD trigger board, with a integrated xt30 instead of a built in booster for top balancing. Problem being maybe if a USB C Input was conncted then also that xt30 was fed a higher voltage than say 12V it might fry something. (Solution off the top of my head being make it so that the xt30 and USB C connectors can’t fit in at the same time)
Idk still wondering why the trigger boards with built in cccv boost and also maybe BMS all in one isn’t available.
If you’re wondering what my use case for this would be, a 3s modular battery that you could hook up a bunch of together or use on their own. As compact as possible and no dongle adapter to charge them.

was looking for this typea thing
but with built in BMS sorta, having two pcb sux

works fine for me

@Battery_Mooch I have been wondering if I did not use a BMS before connecting to the XYPDS100 then the USB C cable got shorted if the pack could get shorted. I assume there is a weak link along the way to save packs.
Put a fuse between the pd board and the battery and then we don’t have to care about what the pd board does when it falls

I like that but thinking about it you should definitely be using a BMS for a power bank.
I guess I only want to know if the BMS would trigger or the XYPDS100 would cut power on short. Would it fry the PDS? sure hope not.
Quick answer = I don’t know.
It all depends on the BMS and the PDS board and how they were designed. I recommend adding a fuse at the battery even if you have a BMS that has overcurrent/short-circuit protection.

My solution to that:
Just put a USB-PD output on your board, and only carry your backfire charger. Use your backfire as a giant power bank to run your laptop.

Maybe a esk8 headlight that doubles as a power bank would be a useful product. Not like it needs to be light in the hand so it could be like 130Wh. Not as useful as a whole 500Wh boards capacity but would not strand you if you accidentally drained it.
