My original small Arbor Rally build from 2016 can be seen here:
Then it all changed here again:
Well finally, here is where it’s come to. The past summer and fall semesters at UF I have been running 2 focbox’s paired with an old chopped up space cell pro. Not very waterproof (although I ran through plenty of Florida afternoon showers), ugly, and this battery has been through hell and back. While it was bulletproof (have ridden it every day for almost a year now in its current form, let alone the hubs and battery on previous boards), I wanted something cleaner.
here is it before I made my upgrades over winter break:
The gameplan:
12s2p (higher speed, less cells than my 10s3p)
FOCBOX UNITY (duh, plus space saving)
Fiberglass case
clean up aesthetic
First issue: so this was a TB 12s2p pack I intended to chop up and fit to my own case; ironically it was longer than my 10s3p space cell. You can see how much wasted space (Plus a random xt90 connector?) is inside the TB plastic shell.
After eliminating that plastic endpiece and the internal xt90, I was closure to the length I wanted. The Rally is a 30" deck so space savings are critical.
Because the UNITY and BMS are almost on top of each other, my fiberglass case required a small hump towards the back; I think it turned out nicely aside from the crappy paint job I did… It was a matt truckbed liner heavy paint that dripped in areas; I should have used lighter coats. Cold weather slowed cure times down, something my Floridian self didn’t account for and there are faint fingerprints in the middle. No time for a repaint though I had to get back to college; it will get beat up in no time anyways!
here are some final images in my dorm room: next board I will finish is my roommates
Additionally, there is a weatherstrip layer between the enclosure and deck for waterproofing. I will also be changing out the long bolts for shorter ones soon, and plugging the old 4 holes in the deck from its previous space cell.
Oh man… my calc 3 was with this polish guy that didn’t know what he was writing half the time. Somehow pulled out a B in that class
Physics with Calc 2 is also horrible, unless you like / understand electromagnetics. “derive the formula for the magnetic field traveling through a semicircular wire” ----> have fun.
I just saw your other build thread, and I actually almost went to Cal Poly San Luis Obispo!
’
I got in there and UF, but going from Florida —> Cali was going to be a big change and overall more money than I wanted to spend on undergrad. I was so close and waited until the last minutes to chose because I really didn’t know which was a better fit for me.
This was a drone shot I got of the city from when I was visiting the school and hiked that trail in the bottom of the photo:
