Revel at the "brand" new competitor in the direct drive Esk8 race!

So hold on. Can you share a few more parameters. I see that it is the standard range battery. What size wheel. How much do you weigh? How far do you travel before shut down.

The standard range batteries are travel batteries. You can get 4 -8 km range out of them if you baby them on speed 2 or 3. However, if you are riding around on speed 4 accelerating hard then it should be no surprise at all that your system shuts down at 40%

40% on a travel battery just does not have enough capacity for any hard acceleration. Larger wheels and heavier rider would just add to this being a case of unrealistic expectations.

The Revel kit is designed for multiple batteries. I think you may not understand the product category well enough if you expect to travel far and accelerate hard on a singel quantity of such a small battery.

I also suspect you may not have a full appreciation of what the 40% means. It means that you voltage is 60% of peak voltage and only 40% away from nothing. Several seconds of hard acceleration can easily cause a voltage crash that takes you down to the minimum voltage and a shut-down

My gut tells me that the only problem with the battery could be expectations.

A travel battery needs to be ridden like a travel battery. Short distances and on speed settigns 2 or 3,

You can’t make a travel battery perform like a pair of XR batteries just by expecting more.

If @ShutterShock evaluated your battery and found no problems then the real solution here might just be to invest in two XR batteries.

I had the board since November and I know how it should ride. There is definitely a problem with the battery. Either way, it is not okay for it to unexpectedly shut down. This is obviously very dangerous.

I guess it depends on your definition of unexpected. I tried the travel batteries. Even with two of them in a 4WD, I expected the drives to shut down soon after I reached 50%.

And I hope you don’t think i’m trolling you. I’m just being genuine in expressing that riders need to have very low expectations of the travel batteries. Small batteries loose voltage rapidly under load. So rapidly that it hard for a speed controller to throttle back fast enought to prevent a shutdown.

In my view a shut down at 40% on a travel battery is pretty normal.

I’ve ridden them a couple hundred miles at this point. The max speed would reduce gradually until 10 percent at which point it would reduce quite fast. I know based on reading this thread not to drain it to 0%. Even when I was riding at around 20mph for 7 miles straight, I still finished with at least 10% left and no unexpected cutouts.

No worriesšŸ˜…. What you are saying makes sense, but I would accelerate hard when the battery is at less that 50% and never had any issue before. I’ll admit though that the acceleration when the battery is below 50% is definitely not as impressive as when the battery is full. Also, when it dies at 40%, I sometimes can’t get it to power back on. If it does power back on, it dies again within a minute.

It looks completely fine to me, all of the connections look intact including the repaired one.

SR batteries do tend to have some sag, and I could see it possibly happening at 40% or less, but that doesn’t quite sound normal to me. It’s pretty hard to say what the best course of action is here.

Not sure if it matters but when I opened up the battery casing, there was a small spark where that red wire connects.

Hm… That is slightly concerning, but that should only be powering the USB board

Static Electricity? Plastic battery case, Shag Carpet?

If you wiggle the connections and nothing is loose, then a static carpet spark is a possibility to consider – especially if it happened close to the edge.

It depends on how deep the voltage dipped before the shut-down and how much the voltage recovers after the dip. Other factors include:
Cool temperatures
Rider weight
Wheel diameter
uphill grade (even very slight grades for the travel battery)
duration of acceleration
Number of previous vibration alerts that you rode past.
What type of range are you getting. Run some tests and take some exact notes on speed 1,2,3,4.

With larger wheels during cool spring temperatures, my range with 2 standard batteries (4WD) was only 2 or 3 kilometers to the first vibration. I had shut downs at 50%. I thought there was something wrong with the batteries. I was confused by the power downs happening near 50%. It’s just the way that it is. voltage levels in small batteries are fragile. They drop like a rock and recover by the time you power cycle. But the recovered voltage won’t take you past your own shaddow.

On a warm summer day with 90mm wheels and running on speed 2, I got about 6 kilometers on 2WD. but on speed 4, not far at all.

At that point, I put the batteries on the shelf for the next time I fly to club med. The travel batteries just are not practical for fun rides with brisk acceleration.

I’m not intending to be dismissive towards your concerns. I just think you won’t get alot of joy from your purchase until you upsize to a battery that has what it takes to have a bit of fun.

How big are your wheels and how much do you weigh?

What charger are you using?

What tires did you eventually go with? 110? 120? six inch?

I just switched to tb 100mm but was having shutdowns on 90mm. I think I weigh under 180 with my backpack on and mostly ride on the flat bike trail. I’m still using the same charger.

The temperature outside during shutdowns was probably in the 60s or 70s (F).

I have gotten between 7 miles and 13 miles of range on flat land during the summer. I was surprisingly able to get the 13 miles while mostly staying above 10mph and averging probably a little under 15mph.

I suppose I could just buy another battery, but would it even last a year? Has anyone had a battery last them more than 1000 miles without any issues?

My batteries have lasted for over 3 years. @Joeeskate has over 2000 miles on his.

In my opinion, you just need the right type of battery. A travel battery is for travel. Great to get you from the hotel rom to the pool at the resort. XR batteries are for daily use. As long as you try to use a travel battery for daily use you will be disapointed. The 100 mm wheels will produce a pretty dramatic range reduction for a travel battery and the larger diameter wheels will also contribute to sudden voltage crashes and sudden loss of power. Gentle acceleration on larger wheels is equivalent to strong acceleration even if you don’t feel it.

Your travel batteries sound perfectly normal to me. Short range, sudden loss of power soon after 50%. The range you are reporting on your travel batteries is much higher than I ever got. If it’s dropped suddenly, then I woudl blame the recent switch to 100mm wheels.

I think you are stressing yoursef out uneccesary. Just buy the right battery. If I were you, I would try the humble approach. Contact revel support and say …

ā€œHey, I just realized that my problem with the battery may just be that I’ve been expecting too much from the travel sized batteries and that i recently switched to larger wheels. Sorry about that. I guess I’ve been sending you alot of emails about something that is not actually a problem with the battery. I wish I knew ahead of time that the travel batteries had these limits. Do you think you could cut me a special deal for two XR batteries. I guess that’s what I really should have bought in the first place.ā€

Also, if you’ve posted anything on a review website that in hindsight seems inaccurte, then corrections would probably generate some good will towards special pricing.

That’s my best advice to get you on track for enjoying your ride instead of feeling bad about it.

I meant has anyone ridden over 1000 miles on a single Revel battery without any issues?

I know you are trying to help but there is definitely something wrong with the battery. Seriously though, why else would I suddenly be experiencing issues with it after already having rid it for a few hundred miles? It is not like I just got the kit, I bought from the first batch, maybe second.

Anyways, it’s probably a dead end trying to get any additional support from Revel especially since it is out of warranty. I am still getting used to navigating this forum and am wandering where I should ask about this issue and get a more technical answer.
