Make sure you didn’t accidentally change the Motor Current Max values instead of Battery Current Max values. It’s a common mistake.
Motor Current Max: Set to 120A
Motor Current Max Brake: Set to -120A
To answer your question about the Battery Current Max values, those are set in order to align with the recommendations from the battery datasheets (safe operating amperages).
30A is in line with the cell spec sheet, but realistically if you really need the power, you could push it to 35A or even 40A, but it can cause excess voltage sag in some situations and may heat up the cells extra and degrade the pack faster. In your situation though, at least 35A is worth trying out while being aware of the risks, 30A is a conservative recommendation
No. In fact, those values are independent of each other. Battery Current Max is the maximum current that should be drawn from the battery while riding. Battery Current Max Regen is the maximum current that should be fed back into the battery via regenerative braking. It is fairly common for the Battery Current Max Regen value to be lower than the Battery Current Max value. Just make sure you’re being mindful to set your values in-line with the types of cells you have in your battery pack.
We contacted Tony about some of the default settings damaging the battery. he said himself “ I don’t think the factory settings are damaging the battery, it’s basically negligible.” also thanks for the reply.
This isn’t to speak against Tony, but the data sheets for the various battery cells should be referenced over all else. Both the PintV and XRV come with default settings that do not align with that of the data sheets. They also come with settings that would allow damage to the battery pack without the proper warnings in place to prevent the rider from doing so. There are many people, in addition to Tony, who are inspecting these values and the safest ones are what are being recommended to the community. Safety is paramount.
Can anyone’s XRV board successfully do the Magic Flywheel?
I have another board with a Thor300, and that one flywheel’s perfectly fine. However, I cannot seem to get my XRV to do it at all… I’m wondering if I’ve set it up wrong, or if it’s just a limitation of this kit?
Would love some more data points, since I’ve re-setup this motor + imu a few times and can’t get this working. If some of you can flywheel, I may try to reset and reconfigure it all again…
It’s completely stock XR except for the XRV kit - so stock XR bumpers and pads and everything (no hooks either).
When I start the flywheel, it seems to try to balance, but then accelerates fast and disengages… I’ve tried adjusting the pitch/roll in App → IMU in increments of 0.3 degrees both ways, but that doesn’t seem to make much of a difference.
The board rides great - no complaints there! But would be nice to get it flywheeling next to my Thor
It’s a very particular process, even when it does work. You have to make sure the board is nearly balanced on its own before you initiate Magic Flywheel Mode.
I figured out how to quick stop, but now I cannot skid. When I go to quick stop the bored just stops dead. How do I make this feel more like the original XR?
I can get it to flywheel if I do it on a hill or if I set App -> IMU -> Pitch to -1 and hold the board slightly off perfectly balanced. (However, -1 is not right, means the board’s nose is too far down while riding. Setting it to 0 makes it perfectly balanced.)
Just seems strange to me that it doesn’t flywheel when the IMU is balanced, but if I put it slightly off balance it does.
My other board with the Thor300 balances very well, so perhaps this is just an XRV controller thing.
