2240 cells
6720 solder joints
50 m of copper busbar
2 kg of solder
& more hours than I care to calculate processing cells

And that just the top four packs, bottom row in production bring it up to a 30 kwh's of useable storage.

PEEEEET

I personally think that you should keep your youtube channel alive, I have never found any of your video's boring but rather inspiring!

You are the reason many of us started in the first place and more will follow through your yt-channel. Really appreciate you taking the time to: Do the video's, edit'em, upload'ing.

cheers from a die-hard HB-POWERWALL fan Smile Missing the video update's already

The hour long video I did on disassembling an e-bike battery has twice as many views as the 1 minute summary version!

Sometimes boring is more useful.

Cheers, Paul
