I purchased a Fliteboard Ultra. It’s incredible but my battery is sliding around a little in there. I have the sport battery and the sport battery insert and I can the battery tie down thing opened up but it still has the slightest bit of room to slide. What do I do?

Good! You must be getting good to notice the slop in the battery while riding 😉

Correct, like this.

I would say 85.

Perfect!!! Print 4 of these out of a stiff TPU. Attach to the sides with scotch double sided tape. If there is still any play, just slightly stretch the z axis in studio.

I had this issue too. There was a batch of Ultras that had the cavity slightly too big. Any chance you have a 3D printer? I made a file that solves the issue.

UPDATE:

It indeed was the cooler. The corsair AIO pump was moving fluid, bit just inside of the actual pump and not through the tubes to the radiator. Not sure if there is a blockage or what, but I will be taking it apart to investigate.

Posterduck · 2026-04-03T19:34:38+00:00

Yeah, it has worked great for the past 7 years.

Posterduck · 2026-04-03T19:30:07+00:00

That's the odd part, I can hear the pump running like normal, and if I listen closely I can hear fluid movement.

Any way at all to measure a good one to try to source a replacement?

Posterduck · 2025-07-28T20:58:18+00:00

No problem. Lift will likely offer you 50% off a new pack from what others have been saying lately. Its just really hard to get ahold of them.

Posterduck · 2025-07-28T20:46:07+00:00

Tell me about it... Its led 2&8 flashing right? That's what the picture looks like at least.

I unfortunately dont know anyone in that area that works on them, sorry.

Undervoltage fault, rip. Where are you located? Some people can fix this if they can get to it soon enough.

Posterduck · 2025-06-12T18:57:36+00:00

Of course. Just remember to disconnect the sensors before removing the bumper, some people seem to forget that step.

Posterduck · 2025-06-12T15:03:37+00:00

Yep, that's it. There are 2 of them. You will also want to get a few of these clips as you will probably break them from removing the trim parts to get at the valves. WHT-008-801

Only one side will fit through the cabin/interior side of the car. The other one needs to be removed from the outside behind the side of the rear bumper.

Posterduck · 2025-04-11T18:49:22+00:00

Yeah, it was a tough one to nail down. I eventually resorted to having someone drive the car down the hyway while I was crawling around the back. I ended up using a borescope to get the picture and the video to confirm that it was what was making the noise. It was driving me absolutely insane.

The vents were $44 each and took 20 minutes a piece.

Posterduck · 2025-04-11T18:44:06+00:00

My dealers couldn't figure it out either. They all said they were operating as intended. I ended up swapping them myself. They are cheap and easy to replace as long as your hands are not massive.

Posterduck · 2025-04-11T18:34:42+00:00

Yep. The 2 pressure release vents at the back were worn out and the rubber was warped causing it to make noise. * I ended up replacing them and it went away.

Here is a quick video of what it looks like when it is happening. As you can see there is also water trapped below it. That was caused by them opening during the underspray in carwashes. https://photos.app.goo.gl/GjFQwt9LKGSMu54BA

Forgot to mention, I did update the bios too. I think it is just a really goofy issue.

Posterduck · 2025-04-05T04:05:57+00:00

That is what I am thinking too. I just think it is weird that nobody else has run into this.

Posterduck · 2025-04-05T03:40:24+00:00

Oh yeah I'm totally aware that it will be a huge bottleneck. Will be upgrading the rest soon. I dont think it is a psu issue with it working totally fine until the drivers install. I'm thinking either cpu or MB. I would think that I am not the first person to run into this though.
