Also, I only used the 100mm wheels during one ride so far.
⌠Youâve ridden that battery for a few hundred miles and are wondering why youâre experiencing issues?
These are 25r cells. They sag in the first place, I didnât realize how old the battery is. What you just said justifies it running out of power at that level lmao 25r cells probably start sagging way worse at 1yr old
I agree maybe asking too much of the SR battery. I personally wouldnât even consider riding or buying those, the XR ones have 30Qâs in them and seem to last way longer
Also, what kind of more technical answer are you expecting? I have personally looked at the connections in your battery, repaired it, and tested it. The fact of the matter now is probably just that the cells arenât good anymore
The only reasons it would stop working like that are:
Broken electrical connection OR
Bad / old cells
Okay, I can accept that answer. Technically theyâre 20R cells, not sure if it makes much of a difference. So it sounds like these cells are essentially trash compared to the 30Qs.
Yeah I guess I donât know what I would expect for a more technical answer. I take it that this issue would have nothing to do with the bms then?
Youâre correct, the BMS is unlikely to be at fault here - I have only seen one BMS issue that wasnât water damage related, and in that case, one of the mosfets somehow broke off lol
Yeah so actually 20R is slightly worse than 25R. Yeah the cells arenât the greatest, they can be used for low amp draw situations, but they donât compare very well to 30Q cells. Thereâs a reason no one on the forum builds with 20r or 25r.
It would be cool to see a Revel battery with 21700 form factor batteries, but if we are looking at the purpose of Revel kit, adding more mass to the battery doesnât benefit its slim form factor and deck-swapping selling points. For now, the 30Qâs or VCT6âs in the XR batteries will have to do. I usually get 12 miles on each of my three XR packs that I have, and theyâre all kinda old
Arenât there any better cells Revel could have used while still keeping the capacity below 160wh? Also, couldnât Revel implement a system that would limit the performance of the kit when it detects the the travel battery so a noob such as myself doesnât cause it to die prematurely. Am I just expected to know to not overpower 20R batteries as a consumer?
Okay, I guess Iâll stop my whining here.
Probably not? Iâm sure they did their research, besides, they are Samsung cells so thatâs already better than ones that use crappy unbranded ones. Thereâs always room for improvement in the future
The system you speak of would not be possible without implementing more electronics and increasing the price of the kit from an electrical standpoint. Honestly who knows, I just usually expect whatever the short range battery option is to be bad on all boards. The only reason boosted got away with their short range option without sag is by using a buck converter and very smart expensive electronics that are made in house
Thatâs understandable. Now if only I could buy one of those stickers on the travel batteries without buying a batteryâ
My XT batteries have all held up very well for the most part. I did have one broken solder joint on one battery but CS took care of me very quickly.
Never even considered purchasing the ST Batteries because as @ShutterShock has stated that almost all suck. I worked for Boosted when we only had the Standard Range 12s1p LifePo4 A123 26650 cells. Absolute trash now but great at the time the Boosted V1 was released.
A larger Revel Kit Battery with 21700 40Tâs would be grand but as was stated earlier it would add size & weight to the kits. Iâd be down but idk what the more casual rider would think.
The trend for esk8 is more & more range though. Some of the last customer surveys conducted by Boosted had âmore rangeâ as a high priority for riders, but Boosted only ever really got to 7-8 miles of range at top speed. Revel is already at about 12 miles.
My main recommendation to Revel would be to eliminate the ST Batteries completely. We got rid of the Boosted Standard Range batteries eventually cause we found that the number of riders who actually traveled with their boards via airplane was very low (you can always just ship your batteries to your destination, not that expensive btw) & it was much cheaper to produce just one type of battery.
My recommendation would be to rename the SR battery to âtravel batteryâ followed by an explaination that the TB offers short range and limited acceleration for customers who require a battery that is accepted by most airlines.
If you are traveling within the US then the TSA rules technically allow you to bring one 300WH or two 160 WH batteries per traveler. So if you are not traveling alone. you could get most places with more than one XR battery. Thatâs assuming that individual airlines donât have more restrictive rules than TSA. But even if they do, its security that checkes the bags not the airlines. From what Iâve seen security does not look up the rules of the airline that is on your ticket, they just apply TSA rules.
Having the travel batteries as an option is nice if you are traveling on a charter flight or traveling outside the US. If you are sneaky you can always swap the guts of an XR into an SR or just swap stickers.
An esk8 does technically aid in mobility sooâŚ
According to the FAA regulation, the 300wh limit rule applies to âA wheelchair or other mobility aid equipped with a lithium ion battery â. So, I guess it does apply to electric skateboards.
It looks like the 300wh rules doesnât apply to international travel.
Man there is a tonne of contradictory info on batteries from TSA, FAA and Airlines. Also poorly written and vague.
This guy explains it better than Iâve seen elsewhere.
Youâre managing to travel at this given time?
Nah, I havenât traveled this year.
From traveling with Boosted Boards & Batteries extensively both domestically (USA) & internationally itâs very hit or miss.
Sometimes Iâve gone through with battery paperwork with no issue & sometimes not. Sometimes TSA has an issue, sometimes they donât. Sometimes the gate agent for the airline has stopped me, sometimes they havenât.
More often than not, you shouldnât have any issue at all but when you do itâs often a pain. Youâre forced to either send the battery in an Uber to someone or risk just having to dispose of it to make your flight.
Certain countries like Japan & Mexico are more restrictive than others so I would highly caution against international travel
Shipping the batteries back & forth via FedEx/UPS is really the only surefire way to get them in & out of your destination IMO.
One year I really wanted to take electric skateboards to club med. So I hollowed out two old landwheel batteires and filled them with 9 volt duracells. They powered one V2 and one V4 Landwheel well enough to spin the wheels at security. Since there are no limits on the number of alkaline batteries, there was nothing to stop me from taking the drives with me --my eletric skateboards were not lithium powered â they were was alkeline powered.
Then I brought four 18 volt drill batteries with me and a work light. Powertool batteries are specifically allowed (under 160 wh).
That allowed me to bring two landwheel V2 drives and 200 WH of power per drive when I connected two 18 volt drives in series.
I was going to extremes to get through security, but the canadian charter flights have very restritive language concerning electric skateboard. No lithium powered small vehicles whatsoever.
I feel like that would be worth the compromise, these 20R cells kind of suck. Would it really increase the size and weight though? The cells are a little bigger but you only need 10 of these 40T cells vs 20 20R cells to get to 144wh if Iâm not mistaken.
No noâŚI think the standard batteries should be eliminated.
I was talking about an XXT Battery with 40Tâs instead of 30Qâs or VTC6âs
& I doubt this is something Revel is considering ATM so just a dream for now.
