It's time for another update on the Teslarossa project where we're repowering a Ferrari Testarossa with a Tesla motor. In this episode we've installed 3 out of 4 of the battery packs and finished the high voltage cabling, with just finishing up of the low voltage wiring to go. We also take a look into what's inside a battery pack, as it's not all about the batteries. Lastly we explain how we're able to re-use the original Ferrari gauges by using a CAN/analogue black box solution.
