I have now got to face up on a design on my PW, orginally I was going to go moduler but now I am thinking of just building one full pack.
The pack is going to be 40P14S with the ability of expansion later on.
Currently, if I go with a single large battery rather than separate modules it will be either:
The second option will give me more amps and I probably wont have to spot weld addional nickel between modules (I got battery hookups older design that has the cutout squares between cells, less current spread, was an accidentalbuy).
My battery has to handle peaks of 100A so in a lot of aspects the second option is better suited, but I cant scale the more than 2.5x (840 additional cells).
The first option will provide better scalabilty as I will be able to add another 2240 cells before I hit the floor, but will need to get the nickel between modules to get current up.
Whats your guys thoughts on this? moduler,single large pack, 2 cell wide modules or 4, what ya reckon?
Thanks
Dave

- 10 cells high, 56 cells wide, with each parallel module being 10 cells high, 4 cells wide.
- Or 2[size=small]0 cells high, 28 cells wide, with each parallel module being 20 cells high, 2 cells wide.[/size]
