Ordered the high dollar computer grade caps x3 and a few other parts. Will do the big order one day this week. Time is just flying by lately......

I know!
Heck I mean heck!
I'm trying to get all this stuff done before concrete season starts again because I'll be too tired to do big time consuming projects then, and I'll just want to ride! :mrgreen:

went to start putting things together today and right away I realized the bus bar wasn't long enough.
I need ~6&3/4" to connect one side of all the caps together. The bar is 12"
Well, back to the bike till I get the bar...
Other than that I think I have everything...

Hay the little dot next to the blu and vio wire means that's the Neutral wire right?

Did you ever get yours going? Mine is going but blowing the ends of the electrodes off.

Ordered some to try out and will let you know how it goes.

I was using 3/8 solid copper but bought Glidcop electrodes from Sunstone Engineering that they recommended for 18650 cells using nickel tabs.

I'll let you know how it works.
