What are internal dimensions of Zumo's battery compartment?

I’m planning to use a LiPo battery pack instead of 4 AA cells in Zumo. Can someone measure inside dimensions of battery compartment without battery terminals installed and post the data here?


The inside of the battery compartment measures 60mm × 57mm × 14.5mm. However, there are some features in the battery compartment to hold in the battery contacts that take up space. You could probably remove those features by cutting them out if you wanted to.


Thanks, Grant. I was planning to remove the ribs from battery holder cover. On second thought, I will probably go with Li-Ion 14500 type cells, in order to get higher voltage, so no modifications will be necessary.
