Added headlight, voltage gauge and another 72v battery mounted on the front pole. So 20s4p in the deck and 20s2p on the front for a total of 20s6p,or about 60 amps discharge. Definitely helped with torque and acceleration from a stop. 40 amps is ok but 60 is better.
Weight is still pretty light, the tires are actually much lighter than the stock ones. If you remove the stock tire you will find about a half inch of jello type material on the bottom side of where the tire makes contact. That adds alot of weight to each tire. A lighter alternative to help prevent flat tires is to use a small amount of tire slime and coat the inside of the tire. Not sure how much it's going to help but it's probably better than nothing.
Anyway now this thing is done.
On another topic I was thinking about designing a wider foot deck that would be able to house battery capacity. If it could be 3d printed at only around 1 inch thick there would be enough space to have a decent size booster pack say a 4s,6p or something. I have not seen anything online but to me it seems like a good option for having a wider deck and not needing to have a battery bag like some of the 48v mods that are available online.
Any thoughts about something like that?
