No. The GoPro Hero 5 is a complete redesign. Firstly, they hardened the GoPro Hero 5 so it does not generally require a housing, other than the frame they provide with the camera. It is already waterproof to 10 meters. You only need a housing if you intend to Scuba dive with the GoPro, or will use your GoPro in a particularly hazardous manner or environment. The batteries, and charger are also redesigned (IMHO, much better.) The only things you will be able to reuse are the mounts. When you buy the GoPro Hero 5, you are getting a better camera, but you are largely buying into a new system - not an upgrade. Hope this helps.
