Hi everybody!

this summer i collected several boxes of laptop batteries, now its finaly done with cracking an testing....

So now iam waiting for parts ....
meanwhile i found a very good deal  from a guy who wanted to sell 13 packs of 80 p. These he had created for its outdoor lighting to do work.
so the packs are not mistreaded.... they are 127amp/pack


the planning is that i will they set to 7S and 2P (one more will make te 14)
And the cells that i tested wil make the 3de P
So at the end will it 7S3P

For celldiers, if you want them to charge properly, they need to be in a line

Hahahaha
yeah they are bit of out balance...

Looks great bud

Little update,

I have done my first pack, not really satisfied
Time is the problem.....

   
   
   

Looks pretty good overall. I know how the time thing gets in the way.

One thing you might want to adjust is either the length of time the solder is on the cells, or get a bigger iron. If solder balls, it's not a solid contact. Most of the solder on those cells are balls, and not a blob. There shouldn't be any curves going "under" the solder, it should be more flattened.

little update...


still doing bleedingtests with the packs , 10 done, 11 to go...


iam searching an long time fore the beste setup parrallel connection...
@photo 2, thats the frame i make for it.



anyone good ideas please?

I was thinking about the same setup as you have.
If i was you, if i...., i would not change it, and keep it this way.
Only to connect everything in the front, is going to be a small hassle, maybe that German powerwall guy, with his copper tubes.
Thats very appealing to me

found his name: owitte, one post back

With that much space in the middle you Will get sag in the packs that eventually can break the busbars. I suggest a proper shelf

Hi all,

I wonder how many amps they could handle.....
