Have you ever wanted to push the limits of electric longboarding (Speed, range, power)? Have you looked at a beautiful, powerful battery or ESC only to realize it would never fit? Do you like carbon fiber and freeride style decks? Have you ever wanted to ride dual-diagonal?
I am lifelong lurker on Endless-sphere and have only just begun to post on electric-skateboard.builders. A little bit of background is necessary then – I’m a biology and biomedical engineering student in Medford, MA (two stops from Harvard and an additional two stops from MIT) who rides downhill and is trying to pick up dancing. After I broke my back in another sporting accident in high school (wrestling), I picked up longboarding for back conditioning and balance therapy. Some of my time is spent researching how to better apply longboard motion and physics to children’s Physical Therapy activities. My research experience there has been largely with Silk, but I’ve got time off to pursue my longboard interests.
Carbon Fiber Decks
I have made three boards – Range, Regular, and Slim. The deck shape and size is the same for all models, however the storage capacity and thickness are significantly different. The compartment space is always 610x170mm (height and width) but has a 43mm (range), 27mm (regular), and 15mm(slim). THESE BOARDS ARE CUT SO THAT THEY CAN BE USED IN SINGLE/DUAL/DIAGONAL CONFIGURATIONS
Examples of storage capacity:
- Range can hold more then 14x Headway 40152S 15Ah Cells capable of 10C (150Amp) continuous discharge. – 14x Headway LiFePO4s equivalent to 12s(15Ah), 6s2p(30Ah), etc.
- Regular can hold 2x S.P.A.C.E cells or batteries of similar size.
- Slim can hold disassembled LiPo pouches or DIY polymer pouch batteries for the slimmest board (like Stary, but DIY).
Because Enertion sells a board for his S.P.A.C.E cell and people are moving away from DIY-LiPo solutions, I plan to produce the Range model first.
50x Boards - Up to $380 per person.
- Mold for the Carbon Fiber Compression deck costs ($2,200)
- Decks will Cost: $179.7 ($8,985)
- CF Lids cost $157.7, Aluminum Lids cost $TBD, Wood Lids cost $TBD ($7,885)
Income , Operating Costs , Net Profit/Loss (380x50)-(180x50)-(160x50)-(2200)= - $200 Debt paid by me. Operating Costs will depend on Aluminum and Wood Lid Costs.
I am also finishing a wattmeter and anti-spark switch that will be integrated into the lid of the board so any battery can enjoy safe-switching and measurement. You’ll know how much power you’ve consumed (wattage, amps consumed, and voltage) is going to help you build better boards and maximize your ride, but also give you an accurate estimate of how much power you have left for the journey home.
