These simple DeWalt contractor batteries are actually 5S2P of Panasonic/Sanyo NCR20700A cells, with each cell rated at 30A continuous discharge. Use them to make your 10s electric skateboard FLY with 60 amps for a fraction of the cost of some worse 'Tesla Cells' packs.. Or build your own unicycle, eBike, or 1000W LED system, anything!
Why dangerously tear-apart and harvest the cells when you can use the packs as-is?

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 (for the skateboard mount). 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.

Remix and use derived part to your heart's content! There are four main tabs:
I'd like to add more! Send me photos with measurements and I'll help fit to your board and/or feel free to fork the design and modify yourself! Post here with your results :D
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.
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.
