That bike shop sure has lots of broken batteries coming in. Do you buy them from the shop?

Hi!

And again more cells, ~ 500 Big Grin. Luckily, mostly loose cells this time already removed from their packs. Saves me lots of time Smile
 

In the meantime I'm also wiring up some more cell holders.


If the cells keep coming at this rate, I expect to finish my upgrade in about 4-5 weeks. Currently I have 980 good cells, with this portion probably around 1400.

The upgrade will just be stacked ontop the current setup.
...So getting close to my 3920 cell powerwall Big Grin

Don't worry, I need about 2 more weeks to measure the remaining cells and probably another 1-2 weeks to solder everything together. So still about 1 month left before I update the cell counter to 3920 cells Wink

Hi!

A short update: Finished measuring all cells. Ended up with 1975 good ones, so enough for my upgrade to 3920 cells Smile
Cells are now sorted in their holders.

 

now comes the soldering part, which is probably the hardest work Dodgy

LOL with that many colors, you should see if you can spell out "18650ED!" Tongue Or "POWERWALL" Or "18650" on one line, and "POWERWALL" and the second line. Then hang them so they are easily visible Wink
