I laid out the 100Ah cells and it quickly became obvious that I wouldn't be able to get them to fit, even if I used all of the space up front in the frame and both of the pannier cases at the back of the bike (leaving me no storage at all.) I then laid out the 60Ah mockups and discovered that I would have plenty of room with them.
36 of the 60Ah cells will give me a 115.2 vdc, 6.91kWh pack, which should yield at least a 45 mile range with 80% DOD, assuming 120 wh/mi. A 36 cell pack will use just under 38 liters of volume, and weigh just over 68 kilos (150 lbs). I'm estimating that the cost for the pack will be under $3000, plus shipping.
The 40 100Ah mockups have been donated to the NTEAA for members to use for making their own battery boxes, etc.
