The bms is only protects for over charging and balancing of the cells. The A123 26650 cellsinside the Onewheel have a max charge rate of 10c which translate to 20amps? The more amps you try to push into the cell more energy is wasted. Doubling the amps only saves like 50% of the time.
The controller and battery box are sealed with a closed-cell foam gasket which is not glued, and they also have vents. The vents are made of gore-tex like material that will repel water that is splashed onto it. However, the vents can't withstand water under pressure, which would happen if it is submerged. The gasket also can leak if enough pressure is applied. The vents are protected from direct water impact by the bumpers, so you should be absolutely fine spraying your board from all angles, riding through puddles, etc., but just don't play chicken with waves which could wash over your board.
It's no problem at all. You can even default one board to auto-sync when it recognizes the board is nearby. Naturally you can only auto-sync to one board.
To disconnect your connection on the board you are currently connected to, go to App Settings and scroll down to the Disconnect button. Then you can go back to My Boards and select the next board you want to connect to.
@keithers I'm goofy and I ride with my weight more on my heels, mainly because I feel I can turn, steer, etc. much more aggressively backside. I try to ride the heels as much as I can, but just to the point where I can still make frontside moves by shifting weight to the balls of the feet- that's the sweet spot for me. I may have shared this with you already but here are 2 dismounts I use all the time: www.youtube.com/watch?v=Nc9EGL1mWeM
Has anyone notice that the GPS really does not work very well while documenting way points on a "ride". I find that if I don't stop and press the gps icon so it re acquires, most of my ride path is lost. All the while, google or apple maps seems to have no problem tracking where I am.
