Replaced IOTA55 DC-DC converter with home-built unit. Iota delivers 55amps, but
voltage drops to 8.5 volts. This device couldn't keep up with very minimalist 12v
electrical system. Entire car converter to LED bulbs except headlights (HID Xenon)
and the Iota still could not carry the water.

Built 800 watt unit using two VICOR 110vdc modules trimmed for 13.1 vdc.
Measured 80 amp output at 12.25vdc for over an hour- about 950 watts. Mounted
Vicor bricks on 9 inch square ribbed aluminum heat sink, with some 450vdc large
value caps on input and output, switch, LED indicator, etc. Vicor modules were $273
each, but quite worth it. This appears to solve the 12v aux power problem somewhat
emphatically.

05/30/2009. Added two more 4-cell batteries to pack by mounting on TIVAR boards
over existing batteries in rear engine compartment. Extended range to 85 miles and
pack energy to 23,332 wHr. System voltage now 120v with a little higher RPM on
highway to 90 mph.

On 6/7/2009, we achieved a driving distance of 161 kilometers (100 miles) on a
single charge. This did take the batteries to a more or less completely discharged
state. We've settled on a recommended maximum range of 85 miles for the vehicle
with the two additional batteries.

6/20/09 Replaced motor cooling air fan and duct with more compact version using
two 12v 125 cfm fans and aluminum shrouding to cool both the DC-DC converter
and motor with less ducting.

09/15/09. Added relay to DC-DC converter to turn it on/off with ignition switch.

10/10/09 Replaced tires with original style 165R15 Wide Whitewall. Narrower tread,
larger diameter, harder rubber - increased range to 107 miles in one run.

Rebuild done December 2010/January 2011. Installed new model Netgain Warp 9 with
New Prostreet 3.44R&P Transaxle and EVnetics SOliton1 controller. 57 CALB 180AHA
cells. J1772 charge port. New battery belly pan holds 11 additional cells underneath.
Results - 190kw power and 150 mile range.
