Design Considerations
There were plenty of things I liked about the first board, but there were just as many things I wanted to change with the second iteration:
-
much larger battery capacity
-
sleeker profile
-
more compact controls
-
integrated charging circuitry
-
dual motor setup
-
integrated cooling
I just recently finished this board, so I havent had the chance to do much field testing, but I am very pleased with the results. Be sure to check out the features tab for all of my favorite aspects of the final product!
Results & Analysis
This project has been an incredibly challenging, rewarding experience. I thought I had the process mastered after the first iteration, but I could not have been more wrong. I learned even more from the process of this build than I did in the first. The electronics, enclosure, mounting arrangement, and overall design of this iteration were all vastly more complex than the first iteration. Even with the added complexity, I am extremely happy with the final results. As far as changes go, there are still several things I would like to change if I could go back and do it all over; I would have sacrificed some of the capacity I currently have by reducing the battery arrangement to 6s4p (still 6 packs in series, 4 batteries in parallel in each pack). Having the monstrous 6s7p battery caused a lot of issues during the battery welding process, reduced the ground clearance I have underneath the case, and of course left many more points of possible errors in the future. Aside from this, I happy with the overall results of the board, and there isn't much I would change. While I don't plan to build another iteration of the e-longboard, I am currently working on an electric motorcycle conversion in which many of the concepts will carry over.
