That’s interesting. I’m still willing to be it’s a connection issue, maybe it’s like something on a parallel cell so once you drop to a lower voltage, it starts having issues.
I’d shoot an email to the revel customer service team
I got this too! But oddly enough, only on my standard range battery. The ext battery doesn’t do this. After I get the first and second 25% notification, it will give a very small power cut, only half a second, and then it will perform normal again.

Could be due to the cells ability to sustain the amp draw, maybe the 25% warning on the ESC reduces power a bit? Hard to say, I only own XR batteries so I’m not sure the exact behavior off the top of my head
With intermittent problems like this it’s hard to say without seeing it or taking it apart

Ya it’s weird man! I don’t get it on the notification, but just when i’m demanding a lot of it. Also were you the one with the drive wheels getting oscillations at higher speeds when under acceleration?
Ya, i pretty much copied my post and sent it over to them.

No, that was someone else. But so you’ve reached out to Revel about this?

Ah, my mistake!
Yup, sent out the email an hour ago.
Is anyone here using Onsra 115s wheels with Revel kit? I’m gonna give them a try and wondering will they work well with Revel’s direct drives motors and with the kegel adaptor?
Theoretically they should work fine if they have a standard kegel adapter. I think I saw one customer with them, however they’re larger than the average wheel and probably softer so I’d expect a range decrease and it will cause more stress on the motors for sure

Me too today. Let’s keep each other in the loop yeah?
I think I came across a review that although these are smaller than the 120mm cloud wheels, because they’re softer the reduce the range more.

I suspect there is nothing wrong with your Revel Kit or battery. Instead, I think you may just need to modify the way that you ride on the last power bar.
As a heavier rider, I interpret the fouth bar as being essentially the same as out of power. On the last bar, I would have to ride extremely gentle and not up hill in order to avoid a power down. If a heavy rider or someone with oversized tires accelerates hard or tries to climb a hill on the fourth bar then rapid voltage sag culminating in a cut-out would be the most likely scenario. Accelerating more moderately, the expected outcome would be a graduated power reduction and vibration alert.
Keep in mind that there are certain combinations that don’t go well together. The ingredients of a bad mix include:
- Heavy Rider
- Oversized wheels
- Steep terrain
- Hard Acceleration (Rider likes to accelerate hard all the time)
- Standard Range Batteries
- Rider has only one extended range battery (no spare)
Pick any two or three of the above ingredients and you should not expect much when you are down to the fourth and last power level indicator.
Heavy loads on low battery levels can cause voltage to drop so rapidly that there is no time for a speed controler to reduce power and issue an alert.
This is not specific to the Revel Kit. It can happen on any Eskate.
Just remember that the 2WD Revel Kit is optimized for battery swapping. It is a medium range vehicle if you are a medium weight rider who accelerated moderately. Its a short range vehicle if you are heavy and accelerate full throttle and have oversized tires and have to climb lots of hills and don’t have any spare batteries.
Does that make sense?
Returning to the list of bad ingredients… 4WD is something that you should consider if three or more ingredients apply to your rides. Sticking with 90 mm (or smaller) wheels is another way to sweeten the mix. Extended range batteries and lots of spares also sweetens the mix.
As a heavier rider, I have very low expectations from the Standard range batteries. I have them on hand incase I want to board a plane. But I don’t count on them for distance or hard acceleration.Standard Range batteries and Oversized tires are a poor combination.

I get what your saying, but:
- I’m 77 kg
- I run the stock wheels (90mm)
- I live in The Netherlands (flattest country in the world)
- I do like to accelerate, but not when I’m below 25% anymore
So on one hand I’m inclined to follow your logic, but on the other hand, only two of us reported this issue thus far, you yourself for instance haven’t had this, or have you?
Despite it being the lighter battery, I wanna feel like I can trust it. And even it being the tiny second that it is, of it throws you off balance, it sucks.
The accumulating voltage sag seems like it’s it. I just wasn’t sure if it was an esk8 thing, a revel thing, or isolated to my kit thing. All your points make sense, and modifying the way i ride is the best way to prevent this, but sometimes i come across steep hill on the way back home and have to just walk up along side the board back up the hill 
It’s one of the big reasons i pulled the trigger on a second battery, is that it’s just no fun on one bar. So i’d rather take both batteries down to 25% and then charge them afterwards. Ideally i’d only be charging to 80% as well, but i’m not that cautious. I also would consider 4WD just for the torque increase. But i would way rather save up for a premium board like the MetroboardX.
I run 85mm caugamas, extended range battery and am 185lbs. But the killer factors are definitely the steep terrain and heavy acceleration. It makes sense, and with lithium it’s really not a huge deal as it was with ni-cads. But like @Matts said, we both have the same issue so it’s concerning but not deal breaking.
Thanks for helping provide some clarity on this issue! Just goes to show, there’s still a ton of things that can be improved on in our hobby and there’s great days ahead when everything will be improved and better!! One of the cool things about esk8 is how much there is to learn and to fix because everything isn’t locked down and hard to service by yourself.
On a side note, my solder joint broke today in the same spot. I suspect it’s because the join’t wasn’t very thick, and i was attaching it directly to another solder point that is higher temp, so i couldn’t meld the two together nicely. So i will have to spend some time de-soldering the old joint a bit and prepping the surface better to attach a larger bead. I was actually running some family friends kid’s on the board and one of them missed out on their turn poor kiddo.

Let me know how you like these! I have been heavily considering them for rougher roads.
I wouldn’t mind the range decrease, but torque decrease or if they wore down fast would be a deal-breaker for me.

I’ve just ordered them, will let you know guys how it rides…
These aren’t compatible with standard kegel. There’s serious design flaw / discrepancy. Get a refund!
lol rip I guess this wasn’t true then
Cancel your order and get the 105mm version of the airless rubber tire wheels which does fit revel’s kegel adapter. There’s an abec style adapter coming out for the 105mm and 120mm discovery cloud wheels For direct drives and the revel kit (what I was told) in the near future too if you want to wait.

The Discovery cloud wheels are an ABEC core, and thus that statement would not apply to these wheels as they are Kegel cores
Is this referring to the onsra wheels?
