Please feel free to point out problems with this package.

Looking at the data sheet and reading the OP, i see a misunderstanding of battery system rating.
The battery above has a 138 AH rating. 12 of them in series will have a 138 AH rating at 144V.
He is talking about a 1000AH pack @144V
That would be 72 batteries!
The post above with a 72V 1000 AH rating would be 36 batteries. 6 series 6 parallel.
