I see that the new OW+XR battery is NMC. I believe the OW+ is a LiFePO4. NMC have great energy density, but limited discharge rates (up to 2C) vs LiFePO4 discharge rates of up to 25C. Hopefully the new battery will be able to supply the brief but very high amperage draws needed for acceleration. As someone who’s been properly injured twice by sudden nosedives, I’m surprised the capacity is only 324Wh. If I’m not mistaken, at 2C maximum discharge rate, an NMC battery of that capacity can only put out 648 watts. Isn’t the motor 750 Watts?

Mine definitely was in mission mode when it cut out - I even checked afterwards. I agree on the confidence issue. I've been loving my second board and I've had zero issues.

The first board (that has dumped two riders) sat unused until today when I went for 3-4 miles, (fully padded!) because the second one was charging. Not as fun when you're scared to go faster than you can run! That being said, it performed flawlessly.

I'm interested in the theory that we can put too much weight on the front and the motor could give up. I would guess that could only happen with aggressive acceleration? I wasn't accelerating, but I was going up a bit of a slope. I weigh 205. Maybe I'll keep riding it fully padded for a while.

I received two OW+ boards while I was out of town. My teenage son (who longboards) caught on really quickly, but then had a nasty fall when the board accelerated, apparently without his input. I rode it this morning and it did a sudden nosedive while rolling slightly uphill on very smooth pavement at 12mph. Mission mode. Skinned my elbow, but knee and wrist protection helped. Board did not turn off. I was too hurt to think about looking at error codes.

The second board is flawless. Not a single glitch in 15 miles today. Mission mode too.

There's definitely something going on with some, but not all boards. I've contacted FM - they suggested it's me moving my sensor foot, since the board would've turned off if there was a malfunction. I could imagine that if I had been carving or going over bumps, but this was silky smooth fresh asphalt. I bet I end up paying shipping to get this fixed. Not cool.
