A project log for DIY 100 KWh PowerWall

an old datacenter UPS can make a decent powerwall for the house I live in.

Ever wonder what a big oopsie can do ? hopefully only one battery was rendered unusable and I had 8 spare to switch them. 

The incident lasted around 3-4 secondes but it was enough to vaporize a screw and melt the lead of the battery. the other battery dont seem to be affected.
