BMS is a battery manager (battery management system) which may have either microcontroller chip (hence managed by software flashed thereon) or simple finite state machine in cheaper Lithium-ion cell protection chip. Since microcontroller is now cheaper than the simpler Lithium-ion cell protection chip, it's now used pretty often in larger battery pack.
Very familiar with cell chip protection. But, I am not with microcontroller chip. I assume the microcontroller chip is used like the protection chip on each cell, except can be programmed for a higher C and used for vaping cells that can handle insane current for an insane hobby.?.? Off to google that one.
One next single cell build, I was thinking of building in a volt readout of the protected (panasonic chipped cell), which are cheap. Just not sure of form factor, with usb charging.
