Got an LTO Toshiba battery from batteryhookup and needed a cradle to fit in my junction box for my meshtastic node. Just gets your choice of glue to set the bottom in. It fits in the front of the case allowing you to use the inside still to mount your rak or other goodies.
Theres space around the battery for any needed airflow and the ability to break out the cradle should you want to place something else there.
