Final touches on the cart/powerwall build. Some test results. Future plans and general update.
Lots of stormy weather, but I got started on the battery cart. Should be able to finish up the remaining packs soon!

Happy Star Wars Day! As a safety measure, I got some acrylic panels to put on the outside of the packs to keep from shorting them out if they touch each other once connected. Please share the link below with friends and family.

Kinda all over the place this week, but made good progress. Great mitre saw technique suggestions! 4 down, 3 to go!
Second cell pack was a doosey. Placed an order, changed my mind, but think I finally figured it out.
I’ve made some progress, had some hiccups and Tom has some headway cells if you’re looking for some. I’m working on several powerwall videos and hope to have them done soon. Storm season is approaching!

BUS BARS! I talk about making bus bars and how I’m planning to connect everything together. You won’t want to miss it! 😀
Cells are tested and sorted, time to put them in the cell holders. There is an online tool to help.
Power2Spare has large, brushless fans for keeping the Opus BT-C3100s cool while you are processing cells. They cut the cycle time down vs the stock fans and work even better on the 1,000 mAh setting. The mod is simple, but I did have issues. Also shows test results.
I walk through my cell processing process to sort cells into groups and answer a question about lead-acid vs 18650s.
