After getting the model of the bottom I can now start to work out how much space I have for the battery pack.
Here is a picture of the model with the battery pack.

I decided to use the E63 LG batteries.
Battery specs:
Nominal Voltage : 3.6V
Nominal Capacity: 63Ah
Dimension : 330(L)mm*120(W)mm*12(L)mm
Weight: 969g
Continuous discharge rate: 2C
Peak discharge rate:5C
I will be using 3 cells in parallel
This is a preliminary model of each 3P cell with cooling plates between each cell.

The battery pack will be 189Ah and I can fit a total of 103 3P cells. (3P103S)
Here is a picture with the battery pack box with the cells inside.

And here is a test run of the cooling plate. I just had to make sure I could make the cooling plates.

Unfortunately to get the full power that the motors and inverters will be capable off I would need 10C peak. So I will have to run at lower power.
My priority was more with total energy instead of straight out power.
It may be possible to get more than 5C if I cool the batteries.
I am still working on how to get the water supply to all the cooling pipes and how to get the bus bars in.
So far I have ordered 40 Cells so I can make a trail pack and see how things go. I will also use these cells for testing the BMS and the inverters.
