Ok it’s not the prettiest thing but it IS a lot of fun to ride up and down hills, especially with the rubber tires

Also why no enclosure

Enclosures are for weenies who fear rocks ending up in their batteries.
Op’s no weenie.

BOOM Roasted!
They’re trampa 12.5 trucks and 6.5" pneumatic wheels. Motors are banggood special 120kV 6384 w/hall sensors, rocks for bearings. Pulley ratio is 66/15, 15mm belt.
Deck is from that website where the decks come from +$5 for grip tape applied. Corners trimmed with Milwakee sawzall.
The receiver and Metr ARE enclosed! It’s that piece of PVC pipe with the gorilla tape on it.

Nice, looks like a flipsky 6.6 dual? What VESC settings are you running?
Something like this would sure clean things up and give you a bit of piece of mind while still allowing easy access to your shit --> https://www.specialized.net/tool-kits-cases/equipment-shipping-cases/blow-molded-cases/armacase-305-medium-blow-molded-case-full-foam-11-x7-x1-9.html
What battery cells are you using, what kinda range/sag?
Also, where’d you find the banggood motors? I haven’t been able to find any 6384 that seem worth buying for less than what I just picked up some flipsky 6384s for on sale.
Flipsky esc is set to hall sensor foc mode, current mode control with brake no reverse. Current is 50A forward 25A brake. Cool thing with the Metr is I can set current low for me and high for my friends, who are much better riders.
Low gearing is because I live in a hilly area, and I am not a good rider, and speed scares me. Also I am 200lb, and my friends are even bigger. My friends are very good riders and they want me to make it faster, so maybe I will switch out to 170kV motors.
The batteries are from the trash at my work. They are burnt up lipos. I only get about 3 miles out of a pair. I have a bunch of 30qs ready to weld into a real pack, which I will do as soon as I get the BMS. Need the BMS to figure out the layout arrangement.
It’s a work in progress. Once I have the cell and bms arrangement I’m going to fold a box for them from .06 aluminum. Once I know how the battery box fits I’ll fold another box for the ESC and radios.

It’s good that you got it working in the simplest possible way. I did that too. Make sure that the esc is foam mounted to the deck or vibration isolated in some way. Vibration will kill your ESC and you’ll be left wondering what mistake you made or just blame the quality of the ESC.

I used the highest quality velcro to mount the esc to the deck!

That battery pack is a fire to come. I would at least cover it with some foam. Piercings make lipo smoke and/or burn. It can suffer a perforation while riding and start a fire later at home. Do not mistake bravery for recklessness.

New battery pack and a sheet metal pan to cover the bottom:
Hopefully I can do a good job bending the sheet metal. Hopefully the many tabs will mate nicely to the curves on the board. Hopefully this will make the board look less ratchet

Are you going to have it lasercut/waterjet cut or just use some shears? I see all those hole and that makes me think you are probably not planning to do it manually.
I am guessing you used the sheetmetal designing so that you an obtain the flat profile to do the waterjet/lasercut??

I did use the sheetmetal design tool and made a flat dxf to cut out. It would be a challenge to cut this with the jigsaw:
So I paid a waterjet to make a few copies so I can practice folding it and I can choose the one I messed up the least. Gonna do it on a brake at work.

If any of you see a story about a special needs person burning down his house in San Diego thats me
But really this is my first battery and it’s definitely scary to put together!

Finished installing case and batteries. Its starting to look like a real board!
Best part is I can only do better from here

I like your style of DIY! Looks well enough made.
Mind sharing how much it cost you to make? I’d assume a good price to preformance ratio.
More details about the battery? - what range are you getting?
Thank you!
The cost sort of depends on if I include things I bought that didn’t go onto the board, like I tried 3 different decks before I settled on this one. I guess if we only count whats in the pictures it’s something like
- $270 for 60 30Q batteries to make the 12s5p pack
- $55 for the deck with grip tape applied
- $110 for two sensored 6384 120kV motors
- $50 for the sheet metal cutout to make the box
- $36 for the controller
- $60 for the metr
- $250 for the FSESC6.6 Dual
- $100 approximately in wiring, connectors, kapton tape, motor pulleys, screws and other odds and ends
- aaaannnd $650 in trampa parts (wheels, trucks, motor mounts) jeez frank give us a break!
I just rode it with the new battery tonight. Before this I’ve been using trash thunderpower lipo batteries from my work, and those only go about a mile before they need a recharge or catch fire. I’m hoping with a 648Wh pack I can get at least 10 miles. New pack is 12s5p Samsung 30Q.
