I Want to Increase the Autonomy of My Electric Scooter, So I've Designed a Box to Double Its Battery Life for Longer Rides. It's Compatible with 36V 8AH Batteries Found Online, Which Are the Most Affordable Models. There Are Two Versions: One with Just a Cable Port and Another with a Cable Port and Two Holes for Adding Illuminated Contactors. You'll Need M5 x 30 Hexagonal Head Machine Screws and Associated Bolts to Assemble It. Depending on Your Printer's Impressions, You May Need to Enlarge the Screw Hole with a 4.8 Drill Bit to Fit the M5 Screw. There Are No Pre-Drilled Holes for the Charging Port, as This Will Depend on the Waterproof Chargers You Choose; However, There Is 3cm of Space Above the Battery to Add Fuses, Switches, or Plugs. The Lid Fits onto the Box and Stays in Place due to Gravures on Both Sides, Which Can Be Reinforced with Scotch Tape if It Keeps Coming Loose After Printing.
