preface: it's for an e-bike with a mystery hub motor and controller I haven't found datasheets on yet. gonna do more research and maybe some manual testing before hitting digikey but

>the 72V battery is going to drain down first because the converter will try to hold 48V exactly while the battery sags.
for the >USE CASE i guess i dont really care too deeply, but wanted that spare battery to drive ancillary electronics. it's for an e-bike so that would mean lights, radios, etc. the dream was to have yet another transformer drive all my 5/12v shit (lights, radios, usb ports) all the time, but only be integrated with the drive motor when i hit the throttle via a shitty 20$ automotive grade relay.

>If you put a diode in front of it I can't see a reason why it would blow up,
i would hope the motor controller i already have has at least some self-protection but getting a Big Ass Diode may be a good idea, thanks

the thought was to do any infra kinda voltage regulation well before "seeing" the 48v battery. so the 72v battery and its converters would be effectively one big unit that "counts as" a second 48v battery in parallel to it.

this but unironically

>Try IT roles in the military?
people who say this as if you're gonna get in instantly and have an air conditioned office resetting passwords and just do it for a year until you get on your feet are retarded, but it's a career option at all. us military pays like shit though but everywhere else that isnt currently in or likely to get into a war is largely fine
