I recently finished my design project. We were designing battery packs for an electric motorcycle!
Teammates Heather and Stan prepping batteries.
~1200 A123 Lithium Iron Phosphate cells, used/tested; cost ~$6000.
Battery module - 13.2V - 18.4 Ahr - about 600 max amps continuous! That's incredible power in a small package. Would cost you over $600
For our motorcycle we will have 32 of these modules all in series! That's 422v nominal!
We're hoping that this pack will help set record speeds!
