So I keep going back and forth with plans on this Haya shortboard. Mainly my battery options and motors/wheels. Have a bunch of motors and it’s time to put this beauty on the street. Two rows 490mm x 91.5mm x 23.2mm as a battery compartment
First thing is there’s a few battery layouts that may be possible or may be pushing it. I have a lot of 33x60mm micro 12s bms with balancing so it allows for far more cells than usual.
More cells would fit on the bms side rather than the unity side. After subtracting put their dimensions it leaves 457mm on the bms side and 373mm on the unity side.
Battery Option 1: 12s5p of the 30q. Thats 15Ah, and 100A if you go by 20A continuous on those cells. That’s stuffing 5p in between the 91.5mm width and 7 vertical within that side.
Potential issues: This only leaves about 4 mm left vertically. In between each cell (8 areas total) there will be about 2 layers of 0.15mm nickel, and two layers of fishpaper (I’ll be using the thin bus bar method that lays on the top of the cells to save space in between the cells). Not to mention there will probably have to be a wire at the far ends to connect the two cell battery halves. This is probably pushing it right? But it would be badass to fit 12s5p in this little beast. Maybe routing out a few mm? I just don’t want to mess with this beautiful deck.
Battery Option 2: with this micro bms, I could fit a 12s3p of 30T cells. That’s 105A, 9Ah.
Potential problems: Wouldn’t have a problem fitting them in but they are so wide that I would have a hard time securing them with Velcro or any cushion.
Battery option 3: 11s4p of 30T cells. Obviously this would be the high discharge option with 140A continuous and 12Ah
Comes with the same issues as the other 30T with minimal space above and below the cells.
Next I have tow motor options:
Torque boards 75 kv with any wheels I want
Hummie 83mm, and wide Centrax style
So which combo would you choose?
