started to get boring during the pandemic and did some research on electric longboards. I’m still having a longboard (Apollo Fidji) laying around, so wanted to give it a try.
Learn some new skills, trying to make use of my 3D printer that is just sitting on the shelf and having fun. Best case, the longboard will give me a decent distance (7-10km) and speed (max. 25km/h). Just cruising some level and smooth bike ways, no serious slope and no off-road driving. This will definitively be no “hard core” or “high end” build. I’m not avoiding pre-build boards or bolt-on kits for financial reasons - I’m just an enthusiast in building stuff (I guess like everyone else here). But please don’t judge if I’m trying to safe some money here and there as I’m not sure if I will succeed at all
Known deficits: I’m a halfway engineer, but didn’t spend too much time in electrical engineering classes - so most of it is honestly just try and error. And sorry if you find some typos, English is not my mother tongue.
Now the specs so far:
- ICR18650-HE4 25000mAh 20A
- 10S2P configuration
- Probably some cheap BMS (10S), bypassing for discharging. Limiting power via VESC.
- VESC 4.12
- Flipsky VX1 remote
- I’m starting from a regular Apollo Fidji board I had laying around
- Wheels are 72mm, so I can already see that it will be critical for the clearance
Motor / Motor mount
- Was really interested in the possibilities, but for simplicity I will go for a belt drive for the moment
- As far as I can make sense on how all is linked together, I can still go for a different setup by changing the trucks (but for sure with the VESC limitation for one motor)
- Motor itself wasn’t decided yet, will wait for the mounting kit to arrive first
- Will be a DIY approach based on Fusion 360 and my cheap 3D printer
- Should make sure batteries are boxed safely in case there’s contact with the ground. Besides that, should not cover the whole board - anyway, just a first draft. I’m pretty sure I’m too optimistic with the space.
- Attached a first draft on how it may look like
- Width: 80mm, Length 300mm, Height 40.3mm, taking the shape of the board, should hopefully work out with the flex of the board if I have some rubber/foam to seal the connection between enclosure and board
- Will go for a XT90S socket for connecting/disconnecting power
That’s it so far - besides the board, none of the components have arrived yet. So for sure the housing might get adjustments as soon as I have a chance to take real measurements.
Have a nice evening
