DeWalt Drill Battery Mount for Electric Skateboard (+anything else)

thingiverse

These affordable DeWalt contractor batteries are actually made up of Panasonic/Sanyo NCR20700A cells in a 5S2P configuration, with each cell rated for **30A continuous discharge**. Use them to make your 10s electric skateboard FLY with 60 amps at a fraction of the cost of some overpriced 'Tesla Cells' packs.. Or build your own unicycle, eBike, or 1000W LED system, anything! Why tear apart and harvest the cells when you can use the packs as-is? Follow this project on hackaday.io to see how it's done! The 3D printed mount is modularly designed in OnShape, making it easily forkable for your own project. The web-based free-to-use GitHub of 3D modeling (a solidworks compatible clone) makes it simple to modify and customize. It's designed to be printed on small 3d-printers with an optional dovetail connection in the middle (for the skateboard mount). It prints perfectly in PLA (or even PETG) with 8% density 80% overhang support and 25%+ infill, requiring zero finishing and fitting perfectly with the batteries. ## Details The source code for this project is available on OnShape. Remix and use derived parts to your heart's content! There are four main tabs: 1. **battery mount** - The basic, no-frills, single mount. No attachments at all. 2. **underside mount** - My original design for my Wowgo Skateboard, with added support ribs that work great! 3. **topside mount** - Perfect for adding ~12miles of range and/or 60A capacity to an existing board or replacing your existing battery altogether. 4. **duo mount** - A simple back-to-back mount designed for non-skate uses. ## Printing Each part can be printed on small 3d-printers like my little $200 Monoprice Select Mini. The larger underside and topside mounts have a dovetail connection that works great without glue to hold things together. All pieces print perfectly in PLA (or even PETG) with 25%+ infill (I use 30-35%). All parts that are printed flat need overhang support, I've liked just 8% density 80º overhang. ## Building Required bits: * The batteries! Available on Amazon * Industrial Male Disconnect Vinyl 10 Blue(34529) from Ace hardware That’s it! Crimp the connectors with some beefy pliers or a real crimper, they friction fit into the mount with the help of some normal pliers. ## Useful References: * Battery teardown and details: DeWalt 20V Max 6.0Ah Pack Teardown & Analysis * Another similar project to this one: DeWalt Flexvolt 60v Battery Adapter * The CAD source on OnShape * This project on hackaday.io * gfycat timelapse of me printing the *duo mount*
