Last night I accidentally over-discharged one of my batteries. Prior to leaving my home I forgot to switch out the battery in my mech. Luckily I had a fuse which is now fried.
This got me thinking, how exactly do most batteries with a PCB work? Is the PCB essentially a built in fuse, wherein the battery is rendered useless if over discharged and the fuse is tripped? Or does the PCB simply tell the battery to "stop" supplying power after a certain voltage is reached? I'm talking about batteries with protection boards, not safe chemistry and IMRs.
Would you still need a fuse if you are using a battery with a built in PCB?
