48 Volt Lithium Project

After building 2 carts for my parents is was finally time to build one for myself.
I found a good 2007 EZ-GO TXT 36V without a controller, knowing I was not going to need the controller anyway. Here are some pictures of how the cart started when I got it home.

the cart was then torn down to get cleaned up and find out all what I needed to do. I had to get the body cleaned as well as it was not going to remain that color. I had no idea what the wiring was like when I bought it and thankfully it mostly all appeared to be there.

Since I knew I wanted the cart to be converted to 48V and I needed a controller, I thought I might as well get a good motor to go with it. I found what I was looking for from Scotty B. and with his advice purchased what I needed. I bought the D&D high torque motor and the Alltrax 500 Amp controller and 400 Amp solenoid.

The next step was to figure the power source. I have seen Lithium batteries in some of the equipment I work on for my job and have always been impressed with the power and technology of it. So I contacted a friend that is getting into the Lithium battery industry, DES (Dynamic Energy Solutions) and he had a couple of 48 volt battery packs that were perfect for what I wanted, so I put in an order for 2 packs and planned on running them in a parallel configuration. With that though, the stock battery tray was not going to work any more. I removed the tray and modified it work with the packs that I was going to receive and I also decided that I wanted the charger and everything to be mounted on-board the cart, so we could just plug it to charge it with a regular extension cord

I then ordered a 4 inch lift kit, got some 21 inch tired, and had the body painted black. I also purchased all new suspension parts since the cart was 8 years old and was starting to have a little sag in the springs and shocks. I figured while it was all apart it would be easier to do it now then later when the cart was assembled. I also installed the motor.

The next part was to tackle the wiring. I had some idea what condition it was in, but since I was pretty much changing the whole system, it took a while to get it all labeled so I could install the parts. I also added a 48V to 12V power converter, digital voltage display and cover plate from Scotty B. This is a very nice set-up and fits perfectly.

I have not seen those batteries. Can you give us some details of where you got them and what their Amp Hour rating is? Nice Cart!
