Hey guys so here is an idea I’ve been prototyping for a bit but special thanks to @mmaner for really lighting the fire under my butt.
This is for holding a brick style pack on a top mount eMTB. My biggest issue with pelican/junction box styles are no customization in size and I don’t like them rubbing the inside of my legs.
The idea is to velcro (or however you prefer to mount) this base piece to the deck.
This top pyramid shell slides over the base and the screw holes align for a pretty solid waterproofing.
The square base section (206mm x 206mm x 70mm) holds a 10s5p liion pack with a bit extra room for connectors.
The top pyramid section will be for my Unity, gauges, and whatever bells and whistles will fit.
The larger cutout hole is for a PG cable gland style plug. This will be attached to the baseplate section and will keep all connections waterproofed and managed. The U shape cutout on the top piece allows you to simply slide the top shell on and off without disturbing the cables.
Neoprene/vibration mats will be between all layers to minimize vibration.
Let me know what you think and if there are any things that could be added or I’m not thinking of!
Forgot about this until recently so I’ve been toying around at work. I currently have 152 cells nicely tucked in the pyramid. 4 more can certainly make it in there (sorry for whoever ends up trying to wire this shape) for a 12s13p pack
