A battery tube installation would work fineBut then you would end up with a tube cap situation like the SX mini, A cap for the battery that screws off & on is a bit of a pain. magnets sound better to me
Kind of wishing I would have bought an ERM enclosure when moderate had them on sale
Probably would be easy enough to put a battery sled in it and mod the back cover with magnets.
