Rate My Lithium PCB: Is it a solid 10 or just meh?

Posted by EstablishmentOdd5653@reddit | hardware | View on Reddit | 6 comments

I just wrapped up a design for a Lithium Battery Management PCB. This board supports multiple battery voltages (4.1V, 4.15V, 4.2V, and 4.36V) and comes packed with features:

Overcurrent & overtemperature protection
Power management reporting (battery level, instantaneous current, low battery alert, chip temperature)
USB and DC adaptive input
Dual synchronous buck DC-DC outputs
5 LDO outputs
Both hard and soft shutdown support, plus external wake-up

In short, it’s insanely powerful (at least, I think so). Thoughts?

you forgot to include the image of the pcb or link to git containing the design. never mind the firmware. also a bms preferably does more than just support different voltages, y9uo need to support actual different chemistries and their preferred charging regimes and curves.

I think the average user in this subreddit does not have the knowledge to properly rate that. I know I personally do not have enough eletronics knowledge to do so. I would even dare to say I can't quite even pinpoint the usage of what you describe. So, eh, sorry, but you might not have a lot of luck in here.
