@ftg they’re already usable as is, still trying to come up with a way to use them safely in series for a higher voltage pack.
or maybe someone needs a lot of packs for some badge project

opened up another pack. it's complete with full bms, balancer, conformal coating and just really good construction. neat.

testing one from the 2023 batch and it’s still over 3V per cell. charging it right now and all seems fine. nice :3
that gives enough time to build a many channels charger jig with monitoring etc.

@malcircuit @azonenberg we‘re transporting them in a polestar 2 which increases theoretical capacity by 60% but effective capacity is still the same :(

@azonenberg eh, it can be stored safely in a jerry can imo. for the batteries we‘re getting a proper storage rack too

@azonenberg that’s around 7 liters of gasoline in energy

@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.

picked 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.
