DIY Lithium Conversion

[bronsonj]

So I see there are many lithium conversions going on, many spending quite a lot to do so. I wanted to play too, but I couldn't spend as much on the project as others.
I paid $550 for the batteries, several hundo on stuff I didn't end up needing. I did end up with an Alltrax controller later, but that's really optional. There are risks with this approach, but I did it for considerably less than the bolt in options.

Start out:
Stock drive train 2011 Ezgo TXT48 in freedom mode with 6" lift and 23" tires.

I removed all six 8v lead acid batteries and the accessory 12v deep cycle batt.

For lithium batteries I purchased two modules from a Chevy volt. A 48v module (12 cell) and a 24v (6 cell) module. I could just use the 48, but it maxed out at 50.4V if you charged it 100% and I wanted more V for more speed.
I could not use the entire battery as a traction pack, so I used 14 cells for the traction pack, this left 4 cells which I am using as the 12v accessory battery. I know those who are familiar are wondering about the max V, we'll get to that in the next few posts...

Also, I did some boneheaded moves that I saw other people recommending, those will also be in the next few posts!

Here is the pack after install Day 1.
