Fast Charging The Veteran Lynx

[@ChrisTorina1]

It’s crazy how in just over a year these wheels keep getting better and better

Brilliant! Now we need a well designed seat for the Lynx, so we can store and transport this charger with the wheel!

[@EverlastingEclipses]

Marty i love you always but you hurt me soulfully when you said "who rides 100v wheel" 😢 sorry im still in love with my Sherman S 😅😢😢😢😂

[@JohnSmith-i8d]

Hey Marty, thanks for showing us how small slim things fit in your hand so well, you should be all set. Not everybody can afford something new so some people are stuck with 100 volt wheels or less

[@ElectricUnicycles]

Yes, I know everyone can't afford the latest and greatest, but I try and feature what's new. Obviously I was joking regarding the other wheels (I have two 100-volt wheels, two 84-volt wheels, and one 67-volt wheel).

[@btran3224]

Huge improvements compared to everything else on the market.

[@mcfly_ev]

That’s wild, definitely want one of these.

[@richsam287]

NingNing charger will do 80-170v. Lots of folks still rocking 100v wheels

[@ElectricUnicycles]

From what I have been told his chargers that go down below 100 volts have a high failure rate. But absolutely, buy a charger from whomever you want 👍

[@richsam287]

@@ElectricUnicycles could be for sure, but I see nothing in ningning's channel or from him either stating an issue with failure rates, the opposite infact in that the 4850 charger that is used in this voltage range is VERY robust and heat resistant. I do like Roger's product, and might have gone with his if 100v wheels were covered.

[@ElectricUnicycles]

@@richsam287 Roger does have a version (he has about 6 different fast charger versions available 😄) that will support 100-volt wheels. NingNing is actually a member of Roger's Fast Charger Telegram group. They communicate and that's why Roger knows that NingNing has had reliability issues with the charger that supports lower voltages. Good luck.

[@richsam287]

@@ElectricUnicycles Yeah but roger only 1 that does 170v.... The point of these cool fast chargers is to be able to use on all your toys. Well at least 4 me it is :)

[@EUCXR]

Hey marty which leatt chest protector is the one you are wearing i like the shoulder protection. I have the leatt 6.5 and the shoulder guards don't protect as much as the one you have on.

[@BonFShaw]

Some quick napkin math shows that when charging at 152 volts from a 120 volt outlet you're drawing at least 14+ amps. With 93% efficiency for the smart charger that's 15 amps total. So, it's not a limitation of Roger's charger but simply the typical 15A wall outlet.

[@ElectricUnicycles]

Your napkin math doesn't quite work for this scenario. First of all, I only charged at ~10-1/2 amps. If it were a limitation of the outlet then the outlet fuse would have blown as the charger drew the necessary current. This outlet is on a 20-amp circuit and my personal workshop has 20-amp circuits. The limitation is with the charger when used on a 110/120 outlet.

[@BonFShaw]

@@ElectricUnicycles I meant that the amperage limitation of the charger @120V is engineered to work with 15A circuits. The charger knows that it's connected to 120V but not the actual current limitation of the circuit breaker. Of course, user-limiting the charger output to less than 15A is also engineered and a really great feature.

[@ElectricUnicycles]

@@BonFShaw I really don't understand what you mean by "... is engineered to work with 15A circuits", from the perspective of this retired engineer 🙂 This bottom line is that this charger, whether connected to a 15-amp circuit or 100-amp circuit, cannot deliver more that ~11-amps when connected to a 110-volt outlet. We are probably talking in circles - sometimes text isn't best for communicating 🙂

[@BonFShaw]

@@ElectricUnicycles I'm sorry for being a burr in your saddle as I don't mean to be, and appreciate all you do. And you're right, texting is a poor substitute for a live discussion. All I'm saying is that Roger's charger is limited to ~11 amps with 120V input because otherwise the charger would/could trip a 15A CB. Therefore it was engineered to not do that by limiting the output to ~11 amps which limits the AC line input current to ~15 amps. In the case of 152V @ 11A with 120V input & 93% efficiency that's ((152 * 11)/.93)/120 = 14.98 amps. Not a coincidence, and a sound design. Otherwise users with a 15A outlet could find their CB popped.

[@ElectricUnicycles]

​@@BonFShaw No problem. I enjoy the back-and-forth. Unfortunately, I must continue to disagree with you from my engineering background perspective. The charger is not that smart 🙂 It's not limiting the current because it "knows" that it's connected to 120-volts. It's a limitation of the electronic design when supplied with a lower input voltage (110-volts vs 220-volts)

[@NahBra_EUC]

Going to get one for sure and tell some buddies. Nice video!

[@AlexGodon-e2j]

@electricunicycles I am from Canada. The link above expired apprarebtly. Is there any other way I can get the Roger charger? The default charger with my lynx basically stopped working I have no idea why. I now need to buy another and would love to buy this one but I have no way of ordering one even through telegram I can’t access the group. Hope you can help thanks!!

[@ShiftySkipper]

What the charge time difference between this Roger smart charger and the stock charger the Lynx comes with?

[@ElectricUnicycles]

About 2.2x faster.

[@Riceman-o1p]

Hi Marty! Can you provide me with the link for those aftermarket wider toe pads? I'm going to lower my pedals and I would love to have the wider toe pads because the stock ones on the Lynx are just too small. I'm hoping that lowering the pedals will help a little bit with stability. I just had my first violent speed wobble. It was near identical to the one that Chooch just posted the other day. It came on strong and fast. Almost crashed. I'm 58 and I do not want to go down at speed! 😂

[@ElectricUnicycles]

[@TheSkinnyshowATL]

With your experience and knowledge how long would it take to charge a veteran links with 10 amps from a fast charger to full power 150 one volts?

[@ElectricUnicycles]

~2-1/2 hours from ~empty

i blew a charge board forgetting to drop the Amp knobs on my v1 Roger charger seems like this is story from the past😇 amazing how Roger get these improve so much... i be waiting for the capable 200v charger since my charger cost me a hefty 450$ Canadian😮‍💨... nice video as always Marty🙏🏻

[@ElectricUnicycles]

Ouch. Yeah, it's nice that you don't have to worry about dropping the current before plugging it into your wheel now

[@BigORider]

Roger hooked it up on this one. After small form factor and then you said quiet… I’m def contemplating this in the future. 😮 now if only an ev charger adapter came with it 🤔

[@EmilioZFG]

Roger has the EV Adapter also for purchase

[@joerana5606]

Did you charge to 100%. Any issue with over charge going down from the top of the Mountain? Have a Lynx on order and contace Roger to get a Rober Smart Charger

[@ElectricUnicycles]

I did not charge to 100% - usually the last 90 - 100% takes a lot longer as the BMS limits the current eventually.

[@hi84690]

does it auto turn off or can you leave it plug in over night?

[@ElectricUnicycles]

It will stop outputting power but the fast charger will not turn off.

[@dustinhankins2153]

Which wheel do you like more? The gt mini or the lynx?

[@ElectricUnicycles]

Except for my longer range wheels I prefer the Lynx to all my other wheels including the Mini

[@javierabad8836]

Hi. Great charger!!! weight? I'm electronic engineer and I can't even imagine how to build a slim charger like this with two or more KW. Which kind of magic have inside? A programmable smps would be bigger for this wattage...

[@RadiantFreeEnergyResearch]

I know, right? i study electrical engineering and mechanical engineering, and when i was looking for a powerful and portable (smallest and lightest models) i was only locating military grade power supplies, which look identical to rogers chargers except they cost approximately 2,000 dollars (yes, around two thousand dollars) after that i gave up on locating a really high powered power supply, and back at that time, i was only looking for a power supply, i was already using my own charger for 1/8th scale rc electric buggy fast battery charging. somehow roger achieved combining an extremely powerful power supply, and an extremely powerful battery charger into a compact area and, keeps the price extremely accessible. Special thanks to roger! I’m looking forward to seeing the video on the even more powerful roger charger, which roger refered to as being even more powerful. So exciting!

[@RadiantFreeEnergyResearch]

I don’t know how roger does it. all that power in such a small space. even my older model roger charger is considered extremely compact for its power output capabilities. rogers chargers are the best!

[@awengirr]

He does nothing. He just buys stuff from China and resell. These are Huawei power supplies made for telco.

[@ullle66]

Just a hint: Just because the voltage is higher, that does not mean you "can" automatically use more Amps to charge! The Charge Amperage still only depends on the ampunt of parallel packs (4p here ) and the cell type which is used. So the Lynx 50e 2700wh technical can take as much charge amps as a /S22/Patton/Mini/Master 50e 2400wh. Nonetheless a 151V Amperage charge is in general "faster". A 134V at 5 amps charges at about 670Watt per hour. A 151V at 5 Amps charge at around 755Watt per hour. Great charger btw!!! Especially for Europe with its 230V system and full amperage capability. To sad that it (because stupid high tax charges) makes no sense to order one from Roger when living in Germany.

[@joerana5606]

I think the Lynx is only 2P

[@grb1969]

I wonder if it would help lower the taxes if the charger is classified as “used” versus “new”? For example, some American buyers of Volvo cars go to Sweden to pick up their “new” car, then drive around Europe to make it “used”, then ship is to the USA at a reduced tax cost. Maybe one could just ask Roger for a “used” charger and avoid paying the unwanted overage.

[@BlaineRush-b8h]

Is it not possible to create a 1kw+ charger with passive cooling? Those fans are extremely annoying, especially when you are charging for hours or at night. I’d also like to see a truly universal PEV charger with 0-200v output, 0-15a input.

[@ElectricUnicycles]

You can't get away from physics. You need a way to dissipate heat so either you use a fan or absolutely massive heat sinks.

[@BlaineRush-b8h]

If the charger consumes 1800w at 90% efficiency that’s 180w of heat to dissipate. Surely if the case was made of aluminum with fins all along the outside, it could shed that much heat. I don’t care if it’s bigger and heavier, I’d rather have a silent charger if possible.

[@ElectricUnicycles]

@@BlaineRush-b8h Did you hear the charger in my video? It was outputting ~1500-watts and was nearly silent.

[@BlaineRush-b8h]

Must have misheard the power when I watched, thought it was signifigantly less. 1500w is definitely nice. I heard it spin up when you unplugged it and figured it went really loud on full power.

[@ElectricUnicycles]

@@BlaineRush-b8h The fan goes full-power momentarily when you unplug it. I was demonstrating how loud it can get, but I think that's when you are running at full 3000-watts output. At 11-amps / 151-volts the fan has been quiet like shown in the video.

[@Riceman-o1p]

OK I'm totally hooked! Been riding the V 12 HT as my first wheel and I have a nice Christmas bonus and I'm ready for my next one! (with suspension) I'm 75% on road and 30% off Road. Veteran Lynx or V 14 Adventure? Not sure if you've had a chance to ride the latter yet but curious as to what your vote is. Thanks!

[@ElectricUnicycles]

I have both wheels in my possession but haven't ridden the V14 too much since it's still down for repair right now, but based on what you wrote I would 100% recommend the Lynx. I see the V14 as primarily a trail wheel.

[@Riceman-o1p]

@@ElectricUnicycles OK cool! Thank you very much! I'm going to switch my down payment to the Lynx. Then I'll keep my V 12 for occasional trail rides as again, I'm 58 so I'm not going to be blasting the trails, just cruising. Thank you for your informative videos and supporting the "community"!

Great vid as always! Question, do you hear some low hummy/static sounds coming from the motor when its idling upright? I got the new (batch 6) Patton with the 50S battery upgrade however I'm hearing those sounds and was wondering if that was normal for Leaperkin wheels.

[@EmilioZFG]

Yup completely normal

[@dnthmn117]

That is normal for LK wheels, don't worry. :)

All wheels have some level of noise when the wheel is on not moving. Without hearing your specific wheel I would say it's normal

I still have my 100-volt (and 84 and 67 volt) wheels, but yeah, the S is feeling a bit "old" now 🙂

[@mikeh6286]

Cool. The noise level was unexpected. What about the weight of it? Technically in an emergency you could charge 84 and 100v wheels with the charger set to 126v and rely on the wheel overvoltage protection. Or better yet. Set a timer and disconnect it. Just dial the amperage down when you're approaching the end voltage or you won't fully charge the wheel.

[@ElectricUnicycles]

I would talk to Roger before attempting what you describe.

[@mikeh6286]

@@ElectricUnicycles He will for liability reasons of course disagree, and understandably so.😁 Doesn't mean it isn't possible. It's not a practical solution anyway, hence the "in an emergency". As long as there needs to be "Do not eat!" labels on glue, using anything outside its main purpose is going to be looked down upon I'm afraid.

[@timwatterson8060]

It should just be a software issue, going down voltage should be more than possible, I'm assuming the vendor he is contracting is using a non programmable ic somewhere inside.
