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.

Wow!
What type of electronics did you there? Like if you use a BMS? What else...?
TIA

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 :) Missing the video update's already
 
I'll just move the goal post & complete the other 1120 I have in the wings :) lol
 
Since i am starting out in the scheme of things, keeo me in mind for cells you are thinking of selling. This goes for pouch type cells too.
 
I love you work and follow your channel in youtube. So do you plan on expanding your battery pack?
 
At the moment I'm working on finishing up the third 10kwh pack (1120 cells) after that I'll stock pile tested cells till I get a larger shed & second inverter. Have plans but also have a wife :)
 
Gday peeeeeeeeet, love ur work and I have almost caught up on all ur vids of the powerwall project, just wondering if u posted ur ebay links here in the forum or r they on individual videos in the description? or the comments???

Cheers M8
