Fascinating video over on Vice about a few DIYers who are building their own Powerwalls, microgrids, and vehicles using “old” batteries. (https://video.vice.com/en_us/video/motherboard-dear-future-build-diy-powerwall-laptop-battery/59cbeb0fb159487b3243424c?ref=motherboard) I’m not sure I would have the guts to put a homegrown Powerwall in my garage, however. A utility building in the backyard seems safer to me. Thoughts?
