In the last video, how could a 24V charger possibly charge a module that would be at least 80 volts even when virtually dead (i.e. 2.5 volts per cell)? I'm pretty sure that like most lithium battery packs, the pack is permanently disabled by the BMS if any cell falls below a certain voltage because recharging an over-discharged cobalt-based lithium ion (like LNM in the Smart) cell can produce a very impressive fire.
So they all bought bricked batteries, thought they would magically come to life, and then were disappointed after dismantling and finding out they are not magicians and can't bring them back to life.
It was cool seeing what the battery looks like.
