Jetson TX2 Power Supply and/or waterproof case

Hello everybody,
I’m looking for a waterproof case for the Jetson TX2 does anyone have any ideas?
I’m also looking for a battery pack with a connection for the Jetson, does anyone know about it?

Hope someone has such waterproof case experience can be shared. For battery pack, it should work if it fits the power supply requests as listed in OEM DG and module datasheet.
