This is a topic I’ve chatted with @Skunk and a few others and wanted to get some input and general feedback based on experience here on optimal mounting solutions.
Deck Mounted: all internals (ESCs, Batteries, etc) are mounted to underside of deck. Ie: standard Hummie deck config. @longhairedboy’s Witchblade.
Enclosure suspended: all internals are mounted inside the enclosure or enclosure segments, creating an ‘e-tray’. Or: Kaly production, LaCroix production, Raptor production.
Personally, I lean towards deck-mounting all internals if I can help it, leaving the enclosure as a protective shell rather than direct weight bearing. I find it easier to do maintenance on these configs as well.
I’ve found some instances such as the Kaly 5.0 enclosure where it made more sense to just silicon pot 4x P-groups into each enclosure segment and run thick series connections between. I kept the Unity inside LoveChild deck-mounted, but the BMS + battery is suspended within the enclosure. My prototipo is entirely suspended within the enclosure for over a year of heavy use without issue as well.
Some have also raised the argument that the enclosure-suspension method can lead to better/easier dampening.
I think with proper dampening and insulation within the enclosure this is a less of an issue.
I’ve been using dual-loc + E.G. Silicone adhesive for internals mounting, with neoprene closed cell foam to fill dead space and dampen batteries/cables.
