Ced's Powerwall

Hi guys,

I just start my powerwall thread with a little picture of my fusing system.





I've placed a little piece of nickel strip behind the tab so it is very easy and convenient to melt some tin there and solder or change the glass fuses. Plus plastic do not heat up at all.
We can see also on the picture a square piece of strip I didn't solder, just to show. On the other side I will place a long strip to parallel cells and this for the 7 series. Finally, top and bottom, copper busbars with lugs both sides.

It's like Paul Kennett's powershelves but I will hang the panel on the wall

I thik I'll start with a 7s48p module (linkable side by side to extend parallel, or top bottom to extend series)

Thanks for reading, comments and advices appreciated ;-)

update 15/12/2017 - I've bought my OSB wood board, will cut it soon and mount the 4-cells holders with zip ties (pictures to come)

18/12/2017 Quick update


I've decided to start with a "up to" 7s76p on a 156x60cm board.

I've broken all 1064 little tabs under the holders and now I have to solder the small bits of nickel strip behind the tabs to create the first side of the fuses receptacles BUT, I wonder if there is any electrical security difference between fusing the negative or the positive side ?

Also do someone think there is a risk of electric arcs by the holes between 2 holders and could capton or electrical tape be eventually usefull ?

WOW that's allot of cell holders. Looks good though!

OOooo, how did u get into my brain and steal my idea!?!?!?

Well, sorta. I'm plannin on them being back to back. At least, that's the idea for the time being. Could change down the road. Waiting for next stage

Hi Cderic,
If I understand well, you will use many holder for your powerwall ? You can fuse minus or positif, over intensity is the same on positif or minus.
No risk for electric arc, as the cells will be same electric potential.
