Sweet. Just the video I was looking for. Thanks for posting it. If you don't mind me asking...I would love to see a followup video with your daughter and your month plus impressions on the upgrade. Also, would there be anything extra that needs to be modded to throw in the 48 volt battery option at your listed link?
@@stxrobstar So far, she has been over 28 miles on it, still not needing charged and has over 22% still in the battery. Yes, you can change out the controller to a 48 volt version and motor to a 650 watt 48 volt then you will get 4 mph more and lots of fun.
@@JOHNDANIEL1 Thank you kind sir. 🥃
Thank you again I finally got it this video really helped and I sure do appreciate. John Lane
I hooked up the lithium-ion battery positive and negative then the charger to the charger port positive and negative red and black I just went out on the scooter and it went about 5 mph and stopped and then I kind of smelled something. I think the controller's burnt. I wish I knew what I did wrong. So now it turns on but it won't go because I think the controller might be gone. It makes me think positive and negative might not be positive and negative. Can you give me any advice John? I can't see how to send pictures but I took pictures
Sounds like about time to come up with a solar sunshade/canopy with a couple of 10-20 Watt panels to give it a shot while it's parked out on the site waiting on the next run...? We need more people like you guys, that take the bull by the horns and not only solve the problem (s) but make improvements, instead of just lollygagging around whining about how bad everything is. Texas must love the hell out of you guys. We are a few still in Florida, too.
Wow. I just bought one and I was thinking about upgrading and your video was the perfect upgrade I was looking for. Thank you for this. Much appreciated!!
I put a good parts list down below the video to make it safer and easier.
Thanks for posting this. I have gone off your video and your answers to questions in the comments, and I have done the same upgrade (without the supplemental tool batteries) to a Razor Ecosmart that I found in disrepair and covered in spider webs on my college campus (U of I). 28 - 30 miles of range if you're cruising at full speed and sitting down, although if you're riding around campus with all the starting and stopping, and flooring it from a standstill all the time, it's more like 16 miles. Top speed is about 20 mph on a full charge, 18 mph at 60% or so. Gravel and dirt roads don't slow it down much, nor does a headwind, and it does around 9 mph through rough grass. It's an unusual-looking scooter, and it gets some (good) attention. You will get your butt and back splattered riding over wet unpaved terrain, or in the rain, unless you go really slow. I bought the same exact 36V 20Ah battery from the link you gave, although I spliced and soldered the XT60 connector wires to the original Razor connector wires rather than using a screw-down terminal. Yes it did result in a redundant double-connector, but that was fine with me. I did not bother modifying the charger or wiring the battery to the built-in charging port on the scooter, but instead ran the charging port wire on the battery over the top of the black plastic tub to hang on the outside. It's a more quick-and-dirty way than what you did, but for those who aren't aware, the battery comes with a hinged plastic cover on the charging port to keep water out, which was a pleasant surprise to see when the battery arrived. It probably wouldn't be hard to cut your own out of spare rubber or cork even if it didn't have a cover. The battery does not seem to heat up at all while charging, though it gets warm from full-throttle riding. I used padding like you did, on all sides of the battery, so hopefully it doesn't get banged up inside there with all the sidewalks and curbs.
That’s awesome man. The problem I am having is the battery doesn’t last very long, can’t go 2 miles and it’s dead and we end up pushing it. I’m going to try this and see what I get
I didn't know you could do that i thought the things inside were only made with one kind of battery, thanks for the update.
Keeping the kids bizzy and happy 👍😎🇺🇸
thank you for this video. I have gone back to this video about 5 times to review the details. This is truly amazing work.
glad she has a handy dad
What a fantastic video, I’ve got one of the scooters and I had to replace the batteries and rewire them. This gave me all the information I needed, and my confidence to feel like I could add a new modification to my little scooter instant subscription from me. Thanks again for the clear and concise knowledge.
There's a couple videos of adding a duel batteries to a scooter. Ebike school and grin technology. I have two 48 volt batteries 10 ah and 13ah using both at the same time with a isolator block 1000 watt Bafang geared rear hub get about 18 miles. Not able to ride it hit train tracks at 35 mph fractured my pelvis. I have been looking for a Dewalt 40 volt charger can't find it. A big props to the sweet little lady for getting her hands dirty and you know it's not proper to ask a lady her weight. 😉
www.discountdepot.com/dewalt-40v-max-lithium-ion-battery-charger.html Arrange testing and shipping if thats possible
PS- You can charge the 40 volt Dewalt battery from any 40 volt lithium Charger if your into a bit of handy man electronics, by placing a 4 wire connector into it and some proper wiring. I did this on a 40 volt Green Worx battery, 2 years still doing good.
I loved the video. Maybe in the future I can upgrade my scooter as well.
Go for it!
Very nice e -bike. Make other videos that can be helpful to others. Even very short video that is less than 1 minute. Cheers John !!!!!!!
Hi my name is lee sir I love what you and miss kira doings a great 👍 job thanks❤🌹
Thanks and welcome
Great upgrade for Kiera’s bike. Wish the manufactures would build them that way in the first place. Quick question for you. Recently picked up a generator with a lithium battery. How do I know if the charge controller is built into the battery?
Draw it down below 10 volts, possibility under 9 and see if it disconnects, or charge it to 14.5 and see if it also disconnects. Most are set to disconnect at 10 low, 14.5 high.
@@JOHNDANIEL1 thanks! Will give it a try
This is a very nice upgrade for range. However I'm concerned the foam padding you have added will insulate and cause the battery to overheat.
It's not thermal retaining foam. In fact it's worthless for holding any heat in or out.
@@JOHNDANIEL1 that's good that was my only concern as the lithium batteries seem to heat up more than sla batteries.
I was thinking that may be an issue also, maybe find someone with a 3d printer to make a plastic insert like it had before
awsome video:) hey im getting ready to upgrade the batterys on my ecosmart.. i was wondering if i need any tools to remove they black plate on top of the batterys:)?
NO, the black protector plate just snaps in and out by tension.
Super helpful video, thank you both!!
Now none of the boys will catch her😂😂
Yep, and the faster ones won't outrun dads bullets!
Thanks for this video it's awesome. I've an electric scooter with a 800watt hub motor and 48v led acid batteries. I want to replace the led acid batteries with lithium ones. Do you have some advice and were just can eventually buy lithium battery? Thanks in advance
The battery sourcing link below the video gets you to a manufacture direct store and just choose a 20+ ah 48 volt battery model for your build.
Thanks for the video! I was able to follow it and swap batteries on my old Ecosmart. I'm looking forward to the new range. I see that several people in the comments were worried about the foam possibly causing heat issues. Have you had any issues? I just cut and used the foam that the battery came packed in and am wondering if I should swap it out with something else.
Just use small pieces to secure it randomly. We did not get over heating from it, but to be safe I cut some of it back and left enough to keep it centered and secured.
@@JOHNDANIEL1 Thanks for the tip!
Are you worried about heat build up with all that foam packed around the battery?
Not yet, It does have a heat controlled BMS disconnect. The packing foam has practically zero insulative value, you can feel a light bulbs heat on the other side of it immediately when you put it up near one. I had a "light bulb idea" of using it for insulating pipes since I get so much of it , hundreds of pieces a year from installing solar, but it would not protect pipes at all.
The other part is the scooters draw is far less than the batteries ability, so unlikely to make much heat even under continuous draw. If it ever does we will replace or change it, it's easy. The charger is just under 4 amps charging too, and I charged it in a bath towel to see if it warmed it when charged but none happened, if I did it with the BMS max of 8 amps It may get warm.
I’ve been studying this video. Great build I’m looking to match! Did you use 36v or 48v battery option? Does fuse and BMS come with battery?
36 volt 20 AH and BMS is in the battery pack. Same one as link below video. Fuse of 20 amp you add if not included but mine had one on the motor driver module.
@@JOHNDANIEL1thank you so much for quick response! Unfortunately, the battery you used is out of stock but I’ve seen info about using 48v and even 60v. Is there any downside of using these voltages other than needing a controller and charger?
@@gregwiesneth3137 Your motor if in the similar bike is made for 28 to 44 volts. So it would not last long with 50 volts hitting it.
@@JOHNDANIEL1 I have the SUP version, no seat. Thank you for the info! I’ll keep an eye out for when the 36v comes back in stock.
Hello! I have the metro HD. Do you think this upgrade would work? The motor is different and space for the battery seems smaller.
Thank you!
Updates on the 36V battery after a year? Still working well?
Excellent, has been cycled over 60 times and still pulling full output.
Hello!
Someone mentioned that they spliced and soldered the XT60 connector wires to the original Razor connector wires rather than using a screw-down terminal. Do I need to use the 6.3mm 3 pins male and female connector in order to do so?
I'm not the same poster, but I also connected to the original connector & wires. I connected them with crimp butt connectors. I cut the 6.3mm 3 pin white connector & it's wires, plus the fuse & it's wires off the lead acid batteries. I cut the XT620 connector off the new battery, connected the new battery's black wire to the white connector's black wire, connected it's red wire to one of the fuse's red wires, and connected the fuse's other red wire to the white connector's red wire. You can then plug it into controllers 6.3mm 3 pin white connector.
I wanted to do this to mine but wasn't sure it would work, cause all the others show lead changes. Then I found yours. I haven't bought yet, because the battery I'm looking at, I'm unsure about.
I'm curious, do you think that the 36v 30ah battery from one of those "hoverboards" would work? They don't have the separate line for charging, so I'd likely need to buy a lithium charger.
Due to being enclosed I chose the one with separate charge circuit. But I guess you can try any source that will fit. The one I did buy was about the max that would fit and 400% more total energy.
What about the sprocket? What tooth should I get for more torque
I have the same scooter. Manual says to charge for 12 hours. If I upgrade batteries just like yours, and use it daily. How long do I need to charge it everyday for?
JUST SUBBED !
Is there a link to the BMS ? I clicked on all the links and did not see it ?
Thank you
That battery pack has one built in.
Awesome ! Have the same scooter will be doing this modification this week.
Hello! At 1:50 you are mentionning getting a spare part. I did not get what it is reffered to. Could you write it down for me and give me a link to the part if you have one? Thank you!
I attempted to "buy a coffee". Pop up read that I had entered an incorrect ZIP code. Instructions never asked for a ZIP?
They do that so they can assure your not the wrong owner of a card.
@@JOHNDANIEL1....Didn't see a place to enter a ZIP. The software was highlighting my CCD in red and telling me my ZIP was incorrect.
Could be because I'm currently in Ecuador?
I wish you had made this video for an unmodified scooter, so the process of just switching the battery types could be simplified for simple folk like myself.
It is simple, go to the link, get the battery you need, then just connect the lithium battery output to the same + & - wires from the lead acid battery, then follow the same method to alter the chargers to adapt the lead acid cable to the lithium charger. All else will work as normal.
@@JOHNDANIEL1 👍
Can you tell me which specific battery combination you got at the link? It looks like there are several of them. Thank you.
I got the 36V20Ah-Charger-XT60, Google is pissy about not scooping ad revenue off you so they block the Ali links sometimes or mess with them, if you ever have difficulty opening them just click open in new window or private window and then you can avoid mega google spam.
Did it have the effect you expected for the range?
Yes, in a big way. Range was under a real 12 miles. Now its in the +30 miles. Top speed is easy 2 mph faster but standing acceleration is not any better than fully charged Lead Acid, however after about 5 miles lead acid take off is sluggish and the lithium is still the same as fully charged in behavior. So, over all, excellent results. Best result is with the voltage maintaining higher the motor runs a tad bit cooler since less amps are needed at higher real voltage.
@@JOHNDANIEL1 Thanks for the info! This is super helpful.
Is that 30+ miles all on the new battery or is that including the tool battery?
@@katiewatson563 Sorta both, 28+ on the new battery but it was still at over 20% charge in it, but she came back on the tool battery since I told her not to fully drain the internal battery. So, I baseline math'd the reply. I am sure just on the internal battery you can get 32 total down to 10% in the internal pack, I just don't push it and the 1 tool battery is good for almost 4 miles so its a great add on.
Hi John, I want to get rid of the stock batteries and add three of the 36v 20ah batteries. Can you please point me to a switch that will allow for three batteries instead of the two battery switch you have in your video. Is there anything special I should know about connecting the third battery?
You need a switch that can field them separately.. A 32 amp 4 position 12 terminal will allow you to shift the polarity safer. amzn.to/3MrauFZ
This one has drawings on the page to show that.
@John Daniel JUNE 14, 2023- Hello, I am 46 yrs old and new to scooter world and never had one. I have walked for years to work and back which is about 2.5 mile round trip. That is getting old so I been looking for past year in research on a scooter. I pulled the trigger yesterday and ordered the one in vid- Echosmart Metro Razor chain driven motor. It should be here tomorrow. For the start I have a couple things if you could input on. Being I have worked on electronics since 80s I sorta understand all this in vid. I will mod the scooter in time but for now I will leave that to the side in the battery upgrade. But have the first question on that part itself 1. Do you see any reason or know of that the battery mod could effect the motor? Being the increase in speed a tad vs the 500 watt motor keeping up with such and any added strain per spec of motor. 2. I do not see a link for the head light itself? Wish you did a vid on the head light and install because I need to put front and back light on mine. 3. Oddly my concern on this scooter is silly at this point and simple. Being- you will find the HD ver or SUP maybe has the front and back rain/mud runners. Meaning the things right above wheels that direct water and such away vs your back spraying water all over you. Can this exact scooter have a part you can get to solve said? Thanks.
The motor is capable of the battery change, it actually is more harmed by the voltage sagging as the lead acid batteries volts drop and will get hotter loading with lower volts. (ohms law). Seems to run much happier. The controller can handle it also, has 60 volt capacitors in it. Numerous headlight kits and tail light kits amzn.to/42H4WNy are on Amazon. The motor controller has numerous plugs that are made for lights, brake function and so on. You may have to test it to verify which ones to use.
As for fenders you can buy 16 to 20" bike fender kits amzn.to/3NdyRXY and using some modification they mount easy such as mounting on the rear basket and making adapters for them.
technically since there's 3 7AH SLAS theres 21AH total its just that the weight and the energy density difference etc etc that lithium runs wayy better than SLA so 21AH in sla will feel more like 10AH in lithium in other words. 🚀🚀🚀👌 i did the upgrade myself too 48V lithium CAOMM battery 1000w speed controller stock motor. speeds are 24mph top which is plenty for me.
It's only 7 amp hours @ 36 volts in the original battery on these. Voltage going up by placing them in series will not raise total amp hours.
In order to accomplish you would need 3x3 7ah 12v batteries.
3 in series and 3 in parallel for a total of 9 batteries.
Would a 48v li ion battery work with this motor as well? If so is it the same process? Sorry i am trying to upgrade my girls scooter and any help is appreciated
i would no do that but some have put a 48 volt motor and control box in them. if you are good mechanic you can mount one but they do not have bigger motors with same bolt set up so you have to make a part for it. dad says if you want more power add a 250 watt front wheel hub motor and change gears on the original motor so you can go 30 mph. kiera.
@JOHNDANIEL1 thank you so much for the reply!! Am just gonna get the same battery as you have
I think the only thing I'm confused about is that wire coming from the scooter charge port to the lithium ion battery, is that two wires coming from there? Thank you much. I'll getcha coffee 2.
The battery has a charge port, and the battery has a output. 4 wires total. The incoming charger has 2 wires inbound to the batteries charge port.
@@JOHNDANIEL1 thank you so much for your help John. About 14 minutes and 30 seconds into your video you cut the end off of the lithium ion battery charger and it looks like it goes into a controller plug that you have to cut, is that controller plug the one that is not being used already in the scooter?
@@JOHNDANIEL1 and at about 15 minutes and 30 seconds you mentioned that you may have to tap into a controller plug and route it to the power of the battery but I'm not sure I understand because the battery is already connected to the positive and negative ports on your switch. Gosh I'm sorry I feel a little thick.
@Јоhn Daniel hi John, so if I did get the positives and negatives right I wonder what blew the 36 volt original controller and why it only went real slow and burnt the controller right away. The battery is definitely a good battery I tested the voltage and it does say that it has 30 amps. I tell you what if you drew me a detailed diagram and sent that to me somehow I would get you two cups of coffee. I know that doesn't sound like a great deal does it I guess I'm not rolling in dough. You have been more than kind. Someone said if the voltage is higher on the battery then on the controller that it could blow the controller. Voltage does registry 42 v and it's a 36 v controller.
Can you Buy the Bike with The 20 Lithium Battery?
No
Can you just add an alternator to keep the battery at 100%?
No.
I have no idea how to attach this battery, your video shows it being attached to an already modified scooter.
you connect positive and negative to the same points the lead acid battery was connected to. but you change the charging cable to use the lithium charger as we show it. ours just has a spare battery 3 way switch in the mix, you can add that too and the video for that is about 30 videos back.
@@JOHNDANIEL1 I wish that made sense to me. I have no idea what I’m doing. I wish I had visual
How’s it holding up john? I’m thinking of doing the same to my niece razor scooter.
Way better than expected
Hi John and Kerah, it’s been a year and I was wondering how this battery held up for you.
Excellent. About 40 full charges, some partial, and at least 250 miles on it.
Heya! I have a question, my scooter is different than yours but same principle, is a SXT 1000W scooter that comes with Lead acid batteries, i bought one of those 100$ lithium batteries out of amazon, Chinese branding, now here's the thing, with the old acid battery i could get 14km (i cant tell you in miles sorry) in one charge, now with the new one i get max 4km only before it dies, here's the kicker, with the old one i could see how much charge i have before the battery died, now with the new one i can see all lights perfectly fine and suddenly as soon as i hit the 4km mark the scooter dies straight away, so i want to know if its just a problem with the battery or it could be the controller, because the old battery was 36v 12ah and the new one is supposed to be 48v 40ah, for which it makes no sense what so ever, if you have any clue lemme know, thank you very much!
I think those bikes had a buck boosting drive controller. Using a 48 volt battery may cause it problems. The controller is made to resist over 44 volts, and the waste energy issue may cause the BMS in the 48 volt battery to shut off. Send me the exact model link, I can check it out. The 1000 watt motor I suspect is 1000 watt German rated LOL, which may mean dual 500 watt windings. So lets see more model info and send battery link too so I can check the constant current to safety cut that 48v battery uses.
It's a scooter not a bike tho 😅 but alas i understood what you said, it is the SXT 1000W TURBO, the scooter is indeed German made so yeah that might an issue, now the battery i bought was the cheapest thing i could find on Amazon and its advertised as a 100ah battery (its not because its made by 13x3 cells totaling something like 48v to 40ah mathematically, because i did the math using in comparison the cheapest samsung cell i found over internet) i can not put any links it seems because youtube deletes the reply so i cannot help anymore 😥
@@diegovillar5926 Send me details to me email, olympicpowercontrols@yahoo.com
What is the brand name of that lithium battery? Thank you
There's a link to it directly underneath the video in the description I can't remember the name right off hand.
@@JOHNDANIEL1 thank you 😀
Whats the top speed on this now?
22
@@JOHNDANIEL1 thank you!
You're really multiplying it by 6 because you only get about half the rated capacity with lead acid batteries, but you get pretty much the full capacity of lithium.
I would say your near accurate on total ability. As is the scooter gets about 12.4 miles max on Lead acid. At 12 miles the Lithium is still at 73% remaining.
So I would say it absolutely can do 4X the range, likely 50+ miles.
Hey John I couldn't find that thread but you said the amperage might not be enough. Does that mean my 36 volt 10 amp lithium ion battery, which is the same brand you have there but only 10 amps, doesn't have enough amps? The original batteries were only 7 amps. I know I'm missing something.
Thanks John
Depends on the BMS in the lithium battery. If its a 10 amp battery with 10 amp draw then it will barely be enough for heavy draw but should work. The 7 amp lead acid is 7 Amp Hours storage, but CCA ( cold cranking amps, the draw on demand like starting amps ) is 22 amps capable. Like a car battery.
@@JOHNDANIEL1 thank you very much John I sure appreciate your knowledge. What I did was reroute the charger port on the EcoSmart directly to the lithium-ion and the power out of the lithium-ion battery to the scooter red and black to red and black but when I drove it only went for a minute real slow and burnt the controller because I didn't use a fuse, dumb head me. Though I've worked on razor EcoSmart scooters for a while changing motors batteries and obviously controllers this one's got me flummoxed. I appreciate your help so very much and I'm not in a hurry because I just got my left shoulder so I won't be working on it for a while but still trying to figure it out. Do you know if a way to send pictures? I could send you could clear pictures but I sure understand if I'm bugging you too much. I must seem as dumb as a rock. I asked the seller of the battery puts out 30 amps. I have those big 15-amp lead acid batteries x 3 in my scooters. Talk about heavy. Thanks much John
@@JOHNDANIEL1 thank you John. It looks like all of those batteries have 35 amp output so I just don't know what I'm doing. Positive negative in and positive negative out, seems simple. I guess I should just give up and go back to lead acid
@@johnlane9590 The Lithium just don't share a charging system, so you just charge through its input and pull power from its separate outputs.
im so lost as to why razor use lead acid in the first place.. its not like lithium batteries r new technology
Using unauthorized components such as lithium ion batteries actually voids your legal authority to operate the vehicle according to the FCC guidelines contained within the owner's manual. I'm keeping the stock batteries in mine and making sure that the tires are properly inflated and batteries are fully charged in order to get the best range possible out of mine.
Kevin?
These things are illegal in most states anyway lmao, mine as well upgrade them
Who cares about FCC, I live in Mexico baby
