Make your 10s electric skateboard FLY with 60A-rated 5S off-the-shelf contractor batteries for a fraction of the cost of worse 'Tesla Cells' packs. These packs have 5S2P Panasonic/Sanyo NCR20700A cells, each rated at 30A continuous discharge. Why dangerously harvest the cells when you can use the packs as-is?

Also applicable to: 20s Electric Unicycle, 10/15/20s compatible eBike, ... maybe rc Tank?

The 3D printed mount is modularly designed in OnShape, and easily forkable for your own project. the web-based free-to-use github of 3D modeling (that's a solidworks compatible clone).

It's designed to be printed on small 3d-printers with an (optional) dovetail connection in the middle. It prints perfectly in PLA (or even PETG) with 8% density 80% overhang support and 25%+ infill and requires zero finishing and fits perfectly with the batteries.

Alright. The source. This file on OnShape. 

Remix and use derived part to your heart's content! There are four main tabs:

  1. battery mount- the basic, no-frills, single mount. No attachments at all. All of the next tabs use this as a 'Derived Part' and the foundation of their designs. Use this as a Derived Part in yours!
  2. underside mount. This was my original design for my Wowgo Skateboard and, with the added support ribs, works great! Without deck-risers the battery clearance isn't really enough, however, so I created the:
  3. topside mount. Perfect for adding ~12miles of range and/or 60A capacity to an existing board or replacing your existing battery altogether. This design includes 5.5mm eyelets for alternative mounting, perhaps to an eBike with a buck boost controller.
  4. duo mount. A simple back-to-back mount designed for non-skate uses. I use a 3D-print of this for charging– and break out the cell-balance pins.
  5. stacked mount hasn't been printed or tested yet. It's designed for the flexible PETG plastic and moves the batteries far forward on my Wowgo deck to help with clearance issues. 

Skip downloading these STLs here (unless you've got my exact skateboard, just want to use the eyelet mounting points, or want a charger-mount). Go fork that onshape design and either modify away or start fresh and include the 'battery mount' as a Derived Part.


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 (all but the 'duo mount') need overhang support, I've liked just 8% density 80º overhang.

  • 1 × 3D printed mount Choose from the four styles in the 'details' or make your own
  • 4 × Blade connectors Available at local hardware stores. Often called 'Make Disconnect', 0.25" tab, insulated, 16-14 AWG

    Yeah, I ran out of filiment on this one :/

    Add connectors

    I found these Industrial Male Disconnect Vinyl 10 Blue(34529) at my local ACE hardware and designed the main power connection around them. They friction-fit nicely with the help of some pliers.

Love the hack! It’s been awhile since you posted this, any updates?

Question- how did you know if your Wowgo skateboard (esc/motors) would be compatible with the Dewalt batteries? Are you on stock motors, if so what are the specs? And what were the stock battery specs?

  Are you sure? yes | no
