6xAA battery mount for 2 wheel robot chassis by stuartm

Last crawled date: 3 years ago

I purchased a cheap 2-wheeled robot chassis which came with a single 4xAA battery holder. I wanted to use rechargeable batteries and power both the motor and electronics from these so I decided to use 6xAA batteries (7.2V). I designed this mount to hold a 3xAA holder on each side directly above the passive wheel, providing a counter-balance for components on the other end of the chassis.
The mount is designed to be fitted using short PC chassis screws although cut-down flat head self-tapping screws may also work. The hole in the front post aligned with an existing hole which needed widening; you will need to drill new holes for the side posts. The battery holders are attached to the mount using 2mm double-sided self-adhesive foam and need to be wired in series.
