Cosmic Meow Backgroundpicked up 1825 li-ion battery packs today. that’s 5475 18650 cells in new old stock 3S1P packs.
that will be a lot of work to repurpose and test the packs/cells. but hey, if it’s free it‘s free.
Andrew Zonenberg@cmb hope you're storing them outside or something that's a lot of dubious batteries
@azonenberg it‘s not dubious actually, they‘re leftovers from a portable spectrometer (first device gen has been discontinued) with bms and all produced in germany with datasheets and everything.
@cmb that's still a lot of stored energy, how many gallons of gasoline equivalent is it
Mallory's Musings & MischiefDang, by my rough estimate, that's something like 50-60 kWh of energy! That's like 2/3 of the battery in my EV!
@malcircuit @azonenberg we‘re transporting them in a polestar 2 which increases theoretical capacity by 60% but effective capacity is still the same :(
Stupid physics. It's only a few hundred kilos of added battery mass. Surely that doesn't affect the efficiency lol
