Default Lithium Conversion (leaf battery)

Well as promised, I would start a new thread on my conversion.
I bought a running 94 EZGO marathon electric about a month ago. It is in pretty good condition and runs decent but has some battery acid cancer on the battery trays but clean body.
It also has a sagging drivers side rear spring, but I am currently replacing the rear leaf springs right now.
My specs are going from 36V (6S1P) FLA to 67V (16S4P) Nissan Leaf battery modules . The end result is 120Ah of battery at 67V (fully charged).
This will have a Orion jr BMS and dual digital display for voltage and current.
I am going to change out the motor to AMD 7124 (Beast, max torque) and Alltrax controller SPM72500.
Upgrade all of the battery cables (2awg), 400A contactor and change out reverser to electric solenoid reverser (Albright SW200).
On board charger 800W.
Add disk brakes which requires bigger rim tires.(got the tires/rims yesterday)at 205/65-10)
Add solar cell (145-150W thin film)
Add 5 panel rearview mirror (done)
Add trailer hitch
Add Voltage reducer (DC-DC voltage converter[30amp isolated out] )
Limited slip rear-end (may have to find txt rear?)

I will add pictures as I download them from my camera.
My goals are a cart that can pull my boat down to the local neighborhood marina (17' Boston whaler), pull a cart around the property and just have fun running the dog. I am not interested in a high speed cart (15-20mph max) and street legal.
