If Tesla(and Bill Dube) can do it why not us. If you had 20 modules @ 50 batteries each. you could easily put out 400 amps, It's 1000 batteries but I bet if you did one module a day you could have it done in less than a month. Just get 18650's with pig tails. Drill two plates with 50 holes each to carry the current & you could make a hell of a battery. Probably air cooling would be enough for a motorcycle. It would be 155ah. Using 3.1ah Panasonic NCR18650A

Technical data
MODEL NCR18650 Capacity (Ah) 2.9 3.1
Energy density (Wh/L) 620 675
Diameter 18.6 +0/-0.7 18.6 +0/-0.7
Height (mm) 65.2 +0/-1.0 65.2 +0/-1.0
Weight (g) ca. 44 ca. 44.5
Nominal voltage (V) 3.6 3.6
Charging voltage (V) 4.2 4.2
Energy (Wh) 10.4 11.2

Specifications above.

The batteries for this pack would weigh 100 pounds. The plates and connections probably under 50 pounds. It seems to me that this would be a very good solution to increase the already very good performance of the current electric motorcycles or it could be scaled down for ebikes and scooters.

AFAIK these cells havent been produced yet.
But with these ones: http://www.toddsmodels.com/Poly_RC_PQ_4900XP_6S_Li_Poly_Battery_22_2V_4900mAh_p/pq-4900xp-6s.htm
you can also try. They are IMHO not worth it, because they only have an expected cycle life of 500...
