May we inquire as to what all of the parts required to do this modification cost? Seems like it is a little above my pay grade but still interested in the details.I am using the 48V e-torque battery to power my compressor and fridge.
I am using a 48V to 24V DC-DC convertor, but same could be done 48V to 12V if you already had 12V accessories. I used a DC to DC by Vicor engineering but there are many good ones that are >90% efficiency.
The higher input voltage means more efficiency so I urge you to run at 24V if you can as you will get longer run-times.
The setup works well, and what is nice with this setup is I don't need to worry about discharging the primary battery. Even after a run down test the JL starts fine, tells you start/stop is disabled while the 48V is re-charged, and as this battery charges at a much higher current you get a very fast recovery when the engine is running.
Let me know if you need any help, but this is not a project for someone not comfortable with electrical systems. The 48V battery is lithium and if you screw up you have a fire on your hands that most fire extinguishers can not put out. This is why Tesla's like to burn to the ground.
