Calculations are in:

Battery planned: 14s10p
Cells: NOS LG ICR18650B4
Cell spec: ~99% life 3.6V 2600 mAh
Pack Watts: 1310.4 Wh
Usable: 1179 Wh @ 88% dod (94%->6%)
Life cycles : 7500 = basically forever for me
75c/cell -> pack cost before assembly : $105 plus tax and shipping
Approx assembled cost: $100/kWh
Avg Range calculation for work commute: 33 miles (25 mph, 30 mph, 45 mph)
* how far bike can travel given my commute

kit:
1500w 48v kit (63v capacitors)
1500/48 = 31.25A output
Assuming 1500w output, 78% motor efficiency,
-> 31.25/.78 = 40A controller input consumption
94% battery voltage : 4.116
94% series voltage: 57.624
Power Output /Input at 94% : 1800W / 2308W

Cells per parallel are 5A sustained
Pack max sust amperage = 50A
Safety Factor: 50/40 = 25%

Hoping all in should be $400 max including the bike purchase.

*To add:
1. BMS to cost
2. Charger to cost
3. The voilamart 1500w 48v kit on ebay is 35A so I'll redo my calc's.
So nominal power output to the ground at 78% eff is actually 1375 Watts.
Max power is 1600 Watts. All calculations at 14s config.
