The Belktronix DC-DC converter finally showed up. For those who don't know the DC-DC converter connects to the 160 volt traction battery pack and convert the voltage down to 12-14 volts that the rest of the normal car stuff runs on, things like the lights and radio. This is not the best looking part I have got for the Audi TT but it comes with a lots of recommendations and promise for years of trouble free operation. Since the web site for Belktronix has very little info on the real mounting size, I had to wait until the DC-DC converter showed up. With the unit in hand I was able to find a place under the hood and build a simple mounting plate.
To handle peek loads higher than the 50 amps that the DC-DC converter can put out, I'm using a four 15 amp hour cells. To mount the battery pack, they will be tie-rapped to a simple support bracket. After they get bottom balanced they will be short proofed.
Three of the battery boxes will have aluminum covers, the fourth and most accessible battery box has a Lexan cover to allow the curious to see the batteries and still make them touch safe.
Next up will be running in the motor and bottom balancing all the cells.
