Controller:

 * 330Vdc(nom) / 300Arms(3ph)
 * liquid cooled (may not need active cooling for short bursts)
 * 7.5kg

Battery:

 * A123 cylindrical. 2.3Ah, 3.2V, 0.070kg, 70A 180Wcont - 2 minute run time.
 * Option(1) 100cells (1p) - 320V, 18kWcont, 7kg (starter/junior pack) up to 30kW/10sec
 * Option(2) 200cells (2p) - 320V, 36kWcont, 14kg (race pack) up to 60kW/10sec

Motor:

 * 50kW over 5800-10000rpm
 * 23 cm diameter, 16 cm long
 * 19 kg

Power balance:

 * 50kW mech
 * Vdc 320V nom
 * Idc - 180A

Weight

 * Controller ~7kg
 * Battery ~20kg, 150x150x750
 * Motor ~19kg
 * Total - should come out at around 45kg.

Summary:

 * Due to Cell Voltage sag, peak available power will drop at higher motor RPMs.
 * Motor slightly oversize
 * Torque controller limited, power is battery limited
