A couple of years ago, I assembled a 16S (60V) lithium battery module out of some Chevy Volt cells

To use it in my Sequoia racer, I'm working on a more secure battery box

The plan

Transferred to steel

Cut out

Bending it up (metal origami)

16S 60V 15AH Lithium battery module (naked)

...& mounted in the box

* Notice the terminal cover with "S" for Sequoia biggrin

 

This 16S module has been sitting all winter

...so, I did an individual cell Voltage test

** All of the cells voltages seem to be still pretty "close" 

...to each other

...& to last falls readings too

Ordered some XT90 connectors (for connecting the battery pack)
...& some 2-terminal Molex connectors (for connecting the wiring harness to the speed controller)

While waiting, I smoothed, rounded, cleaned & painted some parts smile

Doing some assembly on the wheel hubs 

Inner bearing, spacer 

SAM_2365 (1).JPG

...& outer bearing

SAM_2367 (1).JPG

Added a washer to "space" the bearing away from the retaining nut

SAM_2370 (1).JPG

Installed a Castle nut 

SAM_2371 (1).JPG

Adjusted the nut down to where the hub doesn't have any lateral (or side to side) movement

...but, still rotates "freely

...then, marked & drilled holes for Safety pins

Kinda like this
