Adam, before I bought my gen3 veteran sherman late last summer, I did my research, I looked at the crash n burn aspects of the euc/pev world before I looked at the positives, the battery quality has come a long way in 6 yrs.. Thank you for making it plain and simple in your explanation, it helps immensely. Keep on keeping on brother🙏✌🤙

Yes I think the battery quality and EUC engineering have improved immensely since then. The need for increased power and speed unfortunately has led to other consequences. I am quite hopeful that the LiTech solution will greatly improve the safety margins. Enjoy your rides!

Of all the wheels out there it is the best bang for your buck. With my modified seat added on the Nikola is the best wheel I have ever had. That shell is also the most durable of all Begode wheels. You had asked if I still ride my Nikola on another video of mine. I was not able to reply somehow on my “KS Fan Got a Nikola” comment section. I still do and now with the new Litech batteries in place, the Nik is more responsive and safer to use and store in my house.

Great explanations. I’m guilty of regularly draining the battery.

[@AdamU1016]

Thanks! I usually don’t ride if my wheel is less than 50% charged as a cutout can occur if I push my wheel too much. My usual rides are usually 10-15 miles long anyway and my Nikola 100V has great range. I would charge my wheel to full charge on the day of or at least the night before my ride. I would never charge my wheel overnight of course while I am sleeping.

[@ZorgKirill]

@@AdamU1016 that sounds funny. Actually, 0% battery in wheellog or eucworld, is not real 0%. Manufacturers made a big enough margin for safety, and the real charge is 10-30%. That's why you can still ride when programs show 0% while standing still. I often ride to "zero" kingsong 18xl, making 80-100km trips without charging, and everything is ok.

[@AdamU1016]

@@ZorgKirill - You run the risk of a cutout by riding your wheel at low charge. Should you need to accelerate quickly to avoid an accident your wheel could cut out. I top off before I ride if I am able to. In addition, if you are always draining your battery to always low level as I mentioned in the video, the wires and hence internal temperature can get hotter since more current would be needed to power your wheel. When your wheel is at low voltage due to low charge, your current would have to increase to power your wheel. More current can heat the wires, mosfets and internal shell temperature and hence affecting battery health.

[@ZorgKirill]

@@AdamU1016 on low voltages gotways/begodes tilt pedals on maneuvers, even with turned off pedal tilts. I have 16k km experience on Gotway MSP, riding fast and on low voltage often, and had no cutouts. As for the heat and battery temperature on low voltage, it doesn't work in such way. I've spent 2 hard winters with lots of snow and temperatures like -20C and less, riding as usual as in summer, and on low voltages battery freezes faster, not heats up. If at summer I can ride slow on 20-10% charge for a dozen km , in winter the distance become twice as less, if not even smaller, because battery freezes quicker and voltage drops faster. When i get inside warm room, battery % and voltage rises up, because it heats up by warm air inside the room.

[@AdamU1016]

@@ZorgKirill - That’s great that you haven’t had a cutout riding at low percentages. I have been riding the wheel for almost 8 years now and have never had a cutout by being conservative as well as having at least 50% charge when I push my wheel. I have stopped counting how many miles I have ridden long ago. I have no idea. I have changed so many wheels. In the summertime we reach temps over 100 F (38 C) here.

@@phamster18 - You really have a deep appreciation then in what goes on in making a PEV function properly. I think some EUC companies pay attention to details more than others. Despite that, even the most well thought out plan and QC can go awry. The huge explosion with the S20 in NYC was horrifying. It took KingSong over a year to finally come out with a demo wheel. The design and specs were incredible. Unfortunately, the explosion was a big embarrassment for KingSong and now they are going to have to go back to the drawing board and see what went wrong. KS went from 84V to 126V wheel and certainly must have overlooked key aspects that needed to be adjusted. I look forward to see what the seems like rushed wheel Master by Begode will be. To Begode’s credit, they have had much experience with fast, powerful 100V wheels. To go from 100V to 136v is not much of a leap.

It looked like he was bringing back a glass of water which he had then dropped in panic. He just couldn’t think straight. In the case of a phone dropping and then catching fire, the battery pack probably got damaged or was already compromised to start with. The shock was enough to set the thermal reaction into play.

Thanks for the informative video. Genuine question which I have always wondered: Why are fires much more prevalent (at least in my knowledge) on EUCs than on scooters?

[@mikeh6286]

I think that on two wheeled vehicles you can install conservative fuses in multiple locations. Worst case is you blow a fuse. In EUCs a rider would fall if power is cut, and to reduce the amount of failure modes, the complexity is reduced to a minimum. What if you got injured going over a speedbump and had a cutout because the fuse blew. Wouldn't you rather take the chance that the wheel could handle it? That's basically the dilemma.

Can you please elaborate more on number eleven? “Charging 80-90% routinely - Not allowing cells to balance” I’m a new eScooter owner, I have the Kaabo Wolf King GT Pro with the 35Ah 72V battery. How do I assure the cells are properly balanced via charging habits/routines/methods? Thank you. 🙏🏼

[@AdamU1016]

Usually it’s the last 5 percent of the charging that takes awhile to complete. It’s because that’s when cell balancing begins. Having cells not balanced can lead to eventual thermal runaway. The cell balancing finishes about 1-2 hours after the charging light turns green.

[@allemander]

@@AdamU1016 So, you’re saying I should definitely charge my scooter to 100% (how often/every time?) and leave it plugged in for an additional hour to two hours after the charger light turns green, in order to balance the cells? Am I understanding you correctly? I don’t ride or charge the scooter everyday. Sometimes, it sits idle for a week or up to ten days at a time, in between road rides (no off-road use). I’ve never ridden to below 10% battery remaining. I don’t ride in wet conditions. The scooter is only 2 months old with less than 300 miles total and it has never been crashed or damaged (it did fall-over once while parked and scuffed the end of the left side handgrip on concrete when it began slowly rolling forward, then the kickstand folded). It weighs approximately 120 lbs. I always use both factory chargers simultaneously. I’ve never a need to rapid-charge my scooter and I do not own a higher capacity charger than the ones supplied with it. Thank you for any further clarification you’re willing to offer. 🙏🏼✌🏼

[@AdamU1016]

@@allemander I agree with above. Nothing wrong with charging to 100% before a ride. Make sure you charge for an extra hour or 2 after the light turns green for complete cell balancing. Never store your scooter at 100% charge. If you have to store for months, store at 50-60% charge. Battery will have small discharges when stored and that is fine. You never want the charge to go down to 0%. Since you have a scooter and not an EUC, a power cutout is not that bad when you try to demand more from the motor when the charge is low. You will just coast instead of faceplant. It is best to charge your scooter just before you ride or the night before. Never charge unattended of course. You should top off your battery whenever you go riding so that you won’t have to worry about a low charge on your rides. You don’t always have to balance completely your battery if you can’t but having it topped off is good.

Nice one. Thanks! Am I right in saying that distributers e wheels and alien rides are installing safer battery packs than those supplied by the manufacturers in the wheels they sell? This is great if it’s right but why aren’t the manufacturers taking care of these issues? As a rider I would rather pay more, much more even for the peace of mind that my wheel won’t cause a fire... I often ride trails and my wheel is always getting bashed about, I also ride to my local gym who are happy for me to leave my wheel on charge while I’m there... now I’m very worried about this.. what can I do?

[@AdamU1016]

You are right. EWheels and Alien Rides are taking extra measures in battery safety. Begode is too slow to realize that their firmware needs to address the issue of drawing too much current from their batteries. Begode needs to shape up or lose loyal customers. What can we do? Don’t over exert your wheel. I tend to ride about 10 mph below the cutoff speed. Don’t over-torque. Check your battery every 500 miles. Check for any swelling of the batteries. Check the wires. Make sure the inside of the wheel is free of mud as it can impede ventilation. Don’t charge and then leave the wheel unattended. Set a timer. My next wheel is going to have the Litech current and over temp protections in place. In addition, the bigger the batteries in the 3-4 pack configurations the less chance of over discharging the battery and hence less chance of thermal runaway. Have a safe ride!

Or alternatively perhaps it's about time the new tech batteries came on the market to avoid this kind of thing.

To answer OP, one* of the ways to kill the fire in secs is to take out the oxygen surrounding the fire source. Ok. not the only way, after you can engulf the flame with water or an extinguisher during phase 2 of EUC's fire.

@@AdamU1016 From observation, there are two phases when it comes to EUC fire. Phase 1, when gas leaks out off the cell, as soon as there is a spark, we would see a violent explosion. In case of S20, it took 3 secs from gas leaking out of the cell to the explosion. Other EUC fires, from leaking gases> explosions too only took a few secs. So, during phase 1, its impossible to extinguish the explosions with fire extinguisher. After ruptured cells' gases are gone, you enter phase 2. During this phase fire are mostly from the burning plastic shell/tire. During phase 2, you can extinguish the fire with fire extinguisher or spraying water from a hose.

InMotion like KingSong have in their firmware a means to limit the motor from demanding more than what the batteries can provide. Begode in their infinite wisdom wants the rider to have the speed, power and performance in their wheels so they never really limited how much the motor can demand from the batteries. Regarding battery safety, I always make sure I am nearby when I charge my wheel. Any early sign of loud pop and crackle, smoke or smell I make sure to unplug the wheel quickly and take the wheel outside as soon as possible. I always have a fire extinguisher nearby too. There is a Firesak available for sale online too that could help contain such a fire too if you cannot take your wheel out quickly enough. Some also use a huge metal container such as a gun safe or metal receptacle or metal trash can to store their wheels.

Hola Adam, Gracias por tu video Are you completely sure of reason number 11? I charge my battery every day from 60% to 80-90% I never let it go below 20%. Am I causing a possible fire?

[@ZorgKirill]

you should charge it to 100% once in several trips, to balance batteries. Or some time later, it will damage one of the cells.

[@AdamU1016]

Cell balancing occurs in the last 5% of the charge. I usually charge fully to green and then add about 2 more hours charging after that. Charging to only 85% does not result in balancing. You might have some critical low cells that can go bad without balancing.

Mi Nikola plus lately been charging up to 105v don't know what to do isint it surpose to be 100.8V total?:( original 3a charger )

[@AdamU1016]

That’s strange. It should be 100.8 V max. Is that 100.5 V reading on the Nikola shell display? I have the Nikola plus 100 V too. I never had that happen on mine. I would recommend posting this issue on the Electric Unicycle Forums. You will get an answer soon. forum.electricunicycle.org/forum/34-begode-gotway-and-extreme-bull/

[@ZorgKirill]

find an electrician with multimeter, and check the voltage on charger and on the wheel. Maybe charger has lower limit, or wheel controller shows wrong number.

[@elgringodelasscooters9616]

So on euc world app shows normal 100.8 full charge, but now side panel fluctuating between 106V and 110V

[@elgringodelasscooters9616]

What sucks is I have the Nikola plus 100v and it scares me one day my EUC can catch fire :( how do avoid this? Ride slower? Not over accelerating it or even going up to steep of hills? Braking softly?

[@AdamU1016]

I am quite careful with my Nikola 100V wheel. I don’t stress it out. My usual cruising speed is 20-25 mph. The max speed I ever attained was 35 mph and that was only a brief moment. I do charge my wheel in my house and when I do I am nearby and within viewing site of the wheel. Never charge overnight or charge and then leave the house. I also set a timer so I know when to disconnect from the wheel as well as unplug. If you are really concerned, open up the shell and check the battery packs. Check every 500 miles. Check if the packs are swollen. The most common times for the batteries to catch fire is when charging or when it is ridden. Is your Nikola one of the wheels shipped by EWheels from Dec 2019 to April 16, 2020?

[@ZorgKirill]

nothing will save it xD Just watch the voltage after every full charging, it has to be 100.8V. And if during charging, the charger suddenly shuts down and shows green leds, earlier than usually (and with voltage lower that 100.8V) , it's time to repair batteries.

Question related to number 11 I charge my Sherman up to 100% all the time will that be potential issue? Wen not using am I supposed to drain the all the batrry? What percentage has to be stored?

[@StKimage]

charge to 100% to balance cells. If you not riding for some time -best is to keep battery between 50-80% for storage.

[@funnyn3rd270]

Hi I have KS 16xs . Do I have to charge it to full 100% very time I take it out for a ride ?

[@AdamU1016]

It depends on what kind of rider you are. Are you an aggressive or a mellow rider? I can be aggressive with my wheel when I ride so to prevent a power cutout I fully charge my wheel when it is less than 85% with my Nikola 100V. If you are just going for a mellow ride and it is short distance (less than 10 miles) and your wheel has greater then 90% then you don’t have to. I know KS tends to throttle their wheel at I think 80%. If you are a fast and relatively aggressive rider, then just charge to 100% just before you start your ride.

[@Jhovan33]

I have a MSP HT purchased in June 2020, is there a recall on the battery packs?

[@AdamU1016]

If you bought it from Jason of EWheels and affected by the recall he would have contacted you by email regarding the battery replacement process. There has been a delay in the program because of the fire last October at EWheels. Wheels shipped from Dec. 19, 2019 - April 16, 2020 are affected. You can open up your wheel to see if your battery is the LG M50LT.

[@MGSSnakeEater100]

Damn after hearing all of this, we are NOT READY for electric cars soon until companies fix these issues, lol

[@AdamU1016]

I currently have a hybrid car but will still be upgrading next year to a full electric car despite this inherent danger. We have several free charging stations at our hospital. That’s a great incentive. I will just treat my car the way I treat my EUC and it should be fine.

[@AdamU1016]

@Anonymous Panacea - Based on the research I did if your battery is going to catch fire the most common time would be when it is either charging or when it is on and the scooter is being ridden. The best thing to do in my opinion is to make sure you are nearby and readily available when you are charging your scooter. I would not charge and then go to sleep or leave the house. Set your timer on too so that you can disconnect from the PEV and unplug the charger.

[@AdamU1016]

@Anonymous Panacea Solid state batteries are definitely better but are too expensive at the moment. I would just be nearby and in plain view of my wheel when charging. Set a timer too.

Hey adam, I just ordered my nikola + from ewheels.. they sent me an email saying they are putting the Litech Molicel Battery packs and will have to wait about another week to receive.. is there anything I should be worried about? This is going to be my first every EUC and watching this video got me a bit nervous 😬 I don’t plan on pushing it only cruising

[@AdamU1016]

You should be fine. Having the Litech Molicel is extra reassurance. Just don’t overtorque or do extreme speeds. I weigh 195 lbs and have gone no faster than 35 mph which is fast enough for me. I doubt you will be going that fast anyway since this is your first wheel. Cutoff speed is about 45 mph. Don’t leave your wheel in the trunk during the hot summer months. Be nearby when you charge your wheel. Charge on the day of the ride or the day before. When your battery is fully charged don’t go downhill as the battery regeneration can cause a cutoff. Stay tuned for my next video!

I would say that is safer than the 1800 Wh Nikola. You have more amp buffer so less chance of a short circuit. I did have the 1800 Wh Nikola before and never had an issue. You chose a fantastic wheel. That was the best wheel I ever had prior to getting my Inmotion V13. Enjoy!

the litech test at 11Mn 30sec is just a test for overload it does NOT test the case were the mosfet on the mother board short . the fuse they have selected is a automotive fuse NOT rated in voltage we have in EUC. Testing on one fuse only is not a good and sound test, especially for a fuse that it rating is exceeded according to fuse manufacturer datasheet. EUC manufacturer need to select a fuse that have the proper voltage rating and the proper interrupting capacity

[@AdamU1016]

I still think the Litech option vs. the standard Begode batteries is more reassuring. Best way to minimize overdischarging since Begode is not willing to change their firmware is to get the biggest battery packs the non Begode batteries have to offer.

[@MrSpeedyduck]

I think once an EUC caught fire, all of that EUC's under that batch should be RECALLED immediately (and all purchasers of that specific unit should be refunded immediately), and I think there should be a governing body who inspects ALL manufactered EUCs despite of any brand it is before it is sold in the market, this is on top of the Quality Control that these manufacturers are also administering to ensure safety to its customers

[@AdamU1016]

It’s just basically the tech of lithium ion batteries which have the inherent thermal runaway capability no matter which brand out there. There are so many variables involved in the production of the batteries. For one specific EUC to catch fire that one specific pack might have had its own specific production deficiencies that caused the runaway. The other EUCs of that batch might have had no other similar battery issues. Unfortunately, it’s like a game of Russian roulette. I waited a whole year and a half when the Nikola came out and after several revisions and improvements I finally bought mine. I just don’t buy first or second batch wheels anymore. I let the beta testers go first.
