What are you doing about cooling the batteries if they are doing in the sealed box?
Doesn't the tesla have a pumped coolant.
Tesla battery modules are liquid cooled and heated. I'm experimenting with two radiators, one on each side of the bus, and may fit another large radiator over the motor if required. Please see four posts above for photos of the wooden mockups we made (I hope to have real radiators here next week).

Also I've been looking at Leaf batteries, are they not more manageable, for installation.
Leaf batteries are about half as energy dense and therefore deliver half the range today for the same weight and size battery. However, they do have the advantage that they require no cooling, simple heating (just resistive heating pads), and are one third the cost 8)

Vauxhall Ampera batteries are also popular for conversions today.

We spun up the Tesla drive unit for the first time this week... I'll record some video once we have the driveshafts fitted.

In the meantime here's the 'large' drive unit with the open source controller 8)

Main battery box 'floor' structure ready for welding to the bus chassis rails (note holes for fire exhaust valves at each end of battery box) :D

In the next week or so we hope to install the Front HVJB, DCDC, and Battery Heater in the front of the bus. I'm also building a simple cabin air heater box that will use a Tesla blower, PTC heater, and a radiator for recovering waste heat from the motor (probably just the stator cooling circuit).

Today we prepared the two Tesla chargers and Rear HVJB for installation 8)

Mapping out locations for the Front HVJB and DCDC in the front of the bus. Note also the dual circuit brake cylinder 'upgrade' and the EV West throttle pot :cool:

Really pleased with the panels on either side of the battery box 8)
