I've been an electrician for over 30 years and never "herd" the term: "Organic, free range watts". Johnny you crack me up.
No cruelty electrons
*Works great my **Latest.Bike** I have a bad knee so I still get exercise but the bike assists me. I am a big guy so I didn’t think it would go as fast but it works great.*
This is so cool! I’ve been searching for free range watts for many years. Tired of paying for the industrialized abused watts
I feel de pain of industral abuse , yes , stop dat oh ho ho 😀😃😃😣😄😀😊😊☺☺
Thanks for making this video for regular people with a regular budget who have a regular level of knowledge about this stuff. Very relevant. Keep it up.
The caged and abused watts bit had me rolling, you sir just earned yourself a sub.
Would be nice if you told how big your battery is and how long it takes to charge
Very cool!
Now another stepdown to power a fridge or other DC applications
I'll use solar panels all the time. When i'm having picnic or something i'll use panels + mppt collector. No battery, tho bu it's working. 12v 4.5A peltier-based cooler to cool my drinks and stuff. I also use it at the same time to power the musics. Once i brought my old cd-casette boombox with me. Oh boy, those faces when people passed my picnic place. Everyone asked bunch of questions. Explained them. Most of them took it advice and planned the same thing.
I just bought 220w same panel as in this video. I thinks its the same. Manufacturer is Dokio. I already have 2 x 50w similar panels. I can now connect all panels to the Victron bluetooth mppt solar-controller and begin to charge my bike batteries with style :) I do have couple of trike recumbents and i want to user the panels as solar-cover and charger at the same time.
Wow! This is what I have been looking for. Thank you so much. Now I can do cross country tour with my e-bike. My first plan is from East coast to west coast here in US. Based on the experience, I have a second plan riding around the globe.
Btw, if anyone interested, we can create a platform to know each other and then we can do the trip together.
This is cool. Keep Nerdin' Out Johnny.
You might get even more power from your pannels by putting an MPPT solar controler between the solar pannel and the boost converter. But if this makes sense depends on if there is any need to charge the batterie any faster and if the BMS will accept higher charge currents than you already get now.
You must have a MPPT boost controller to regulate the charging ruclips.net/video/VjnYeoK6wCo/видео.html
With any thing over 300w u deffintky need a mppt controller also i would suggest it because it is a little safer and provides the power u need
great. I would cover the battery to shield it from direct exposure to sunlight, otherwise it'll severely reduce its efficiency/longevity to the best of my knowledge. I often use some little parasol etc.
Absolutely. I only left it exposed for video purposes
@@JohnnyNerdOut Ok !
Thank you for the video man it was awesome it helped me out a lot I was looking at the charging panels foldable that they have for e-bikes but them things are $2,000 $3,000 I can't afford that your idea dude it's the best thank you🇺🇲👍👍💯🇺🇲
You should get that corner of shade off of the solar panel. Yeah, an angle helps too, but you really want to get that shade out of there. You could also get a bunch of 12 volt panels and put them in series to get 48 volts. Small cheap flexi 12 volt panels to carry on your bike. . . . you would still need a charge controller than handles that kind of voltage.
Nicely done!! The corner of the panel being in the shade kills the output surprisingly. Cool setup.
This has been continually more helpful than all the other videos I've seen on the subject just because it showed parts thank you you shirtless ingenious man
Even at 33 Watts, it would take about half a year to charge that battery 😂
Idea is solid and proven to work, absolutely.
But you're gonna need beefier components(and an MPPT charge contorller) to speed up the charging process to be useful in daily life.
I mean, a net-adapter charges at 2 to 4A and still take several hours to fill a battery.
Amazing! Pretty much exactly what I was looking for
This is the most direct approach to charging. But what about charging when you're on the move with that bike? :) Need to make some kind trailer for the panels, or like me use them as solar-cover and charging :)
Cool project, my way is just to charge a deep cycle battery with the solar, then hook up a converter to the battery and plug your bike charger into the converter
I'm glad you figured that out for me... to go w/ my Dokio 200w panels. I'll probably buy a box to mount the meter and voltage transformer in together just to "neat-it-up" a little. Thanks again. Now if the fuel is all gone I'll have a way to charge a ride until someone steals it from me at gunpoint. Oh yeah... I like the "free-range" watts better too. "WATT" a swell guy you are!
You need a big battery that takes in the same amount that you consume. The best solar bike must be built with heavy AGM batteries or lighweight Lifepo4 able to charge and discharge at the same time. With lithium ion you cannot charge and drive in the same time.
Secondly, don't use Dokio solar panels again because they have poor efficiency.
You need folding renogy solar panels mounted directly on a solar trailer.
You need 600watts of solar energy, long trailer.
You need an efficient MPPT SOLAR CHARGER WITH LCD PROGRAMABLE VOLTAGE UP TO 72V TO ADJUST IT SAME AS YOUR EBIKE.
You cannot just stop to charge your ebike on the ground.
You need continuos charge when you drive. Never use lithium ion again.
I have a solar trike and solar trailer converted, with Lithium titanate Yinlong, best battery. 250Ah 48v bank. My consumption is around 1000w and my solar power is 150w on the trike and 900watts from the trailer. Only lithium titanate YINLONG can take such a massive charging speed. A normal bike its charging with 90-110watts
Per hour which is useless if you want to drive all day sun power 450km range like I do with LTO YINLONG untill gets fully discharged from 8 30pm till 11pm depends on how much sun was coming after 6pm in the evening.
My maximum range in a day was 457km with 45km per hour speed.
Thanks for the info
You need a Battery Charging Controller like a XH-M604, after the booster or else the panel will overcharge your battery. The module will stop charging when it get full.
good point, but lucky at half an amp it could take more hours than he has daylight
his oem battery has OCP.
Great deal if trail camping on a e bike with single wheel trailer like what I would love to do. Thank you.
You have the solar panel partially shaded and not propped up so it's 90 degrees to the sun. Just imagine how much you would get in if you did that. Just use a deck chair or something to prop up the panel a bit better. The way you have it set up, I'm surprised it's pumping out more than 20 watts. Even a tiny bit of shade on the panel depending on if the panels are in parallel or series will kill wattage dramatically. If you want just fool around with the panels until you see more wattage coming in. I use a programmable MPT-7210 boost converter for my solar charging. It's not the most efficient but with two 120w panels in series I'm getting around 110w or just over 2amps. Of course one of the panels has been severely raped over the years so I'm lucky to get mid 80's out of it. So it doesn't help any. I'm sure if I changed out the bad panel, I would get around 2.5- 3.0 amp in on a 48v battery with a terminal voltage of 54.6v. If a panel even has a small corner shaded, you'll lose power. Great video.
I have been running this system for about 4 years now. Only I run a 600w dcdc boost converter. This gives me up to 2 amps max. ( which I limitted as I use it from a car cig. Socket if Im travelling) I also have a 1200w dcdc boost converter which I use at home to fast charge. It is plugged into a solar powered leisure battery that I use at home.
You have link's to these products?
make a sun shade . for riding bike in shade . while charging . wing to lighten u up . get more miles per solar day ! solar sail .
working on it
You have a shadow on the bottom right side of the panel
We the cells are in series the shadow will effect way more Cells than just the shadow area.
No shadows = 100% output
Yep, I’ve learned that the hard way. 😐
If we want to be sustainable, we need to charge e transportation with solar panels (bypassing the inverter which "steals" power).
Good thinking! Thanks for sharing!!!!!
That's right. Just use a boost mppt like I do with programmable end voltage
Hey Johnny. I have a question not involving solar. My heybike Brawn... I know, hubdrive, don't hate me. Anyway, my hub is 750 watt and controller is rated to 25 amp max out put, my battery is also rated @ 25 amp max discharge. So if I want a higher output controller, will my battery even allow this. I don't know if some controllers have potentiometer that are adjustable for higher output. You're absolutely right about hub motors having absolutely no torque but the bike is suited for my purposes currently, I just want a little power gain due to me weighing 220 pounds and usually packing another 30 to 50 pounds on the bike. Id like to convert to a torque sensor eventually but I don't want to void my warranty so I'm waiting on some of these upgrades. Enjoying your channel and your sense of humor. Keep up the good work and hope you fulfill your dreams.
The controller is limited by what the battery can do. Even if you put a 150 amp controller if would only pull 25 amps if that is what the BMS is max set to. 👍
@@JohnnyNerdOut again, thanks very much. I do okay with the mechanical stuff but I need to read a book on the electronics.
How long does it take to charge fully in nice sunny day?
With this never. Sun would go down long before then. With a decent portable solar panel that’s more expensive you can get 200 to 300 watts of output in ideal conditions unlike the 20 watts this guy was getting. Then you could charge a 500 watt hour battery in 1.5 - 2.5 hours and a 1000 watt hour battery in about 3.5 - 5 hours. If you are in poor conditions and you don’t angle it towards the sun as it moves then expect 2 thirds of that speed or as low as half that speed
i’m really shity conditions. They would put out enough power that your main concern should actually be if you are charging batteries too quickly. Shouldn’t charge a battery at more than 1c for optimal amount of charge cycles. Would take about as long just plugged into a normal outlet. Looking at about 200 to 300 usd for a solar panel like this. Just do your research and don’t get scammed and buy junk. There is lots of fake and unethically overpriced solar panels on the internet for sale.
You can buy second hand solar for around $50 , just don't expect to get new
Organic free range watts. Unlike those watts you get from your power company which have been caged and abused thier whole lives. I lost it. Hilarious.
It could burn the battery fuse if anything goes wrong and stops there the charging . Not recomended but high risc taken thinking about what ebikes cost .
I came to the video for the solar charging. I stayed cause your shirt was off. Lol.
hum, 1000Wh/20W=50hours to charge a 48V and 20Ah battery. Its maybe a good enough setup for some peoples but dont rely on that for a road trip!
True
What are the specs of the eBike battery and how long would it take to solar charge from 20% to 100% with this set-up?
Mine takes 4 hours with 390W panel and 400W controller ruclips.net/video/VjnYeoK6wCo/видео.html
At .3a to .6a probably 3 to 6 days of good sun
Free-range watts . . . no watts were hurt in the charging of your bike!
the battery is pulling the voltage down to what the battery. as It charges it will come up to what you set it at. then it will cut off.
to us noobs making connectors is super scary cuz we are afraid to fry our components!! we need a step by step tutorial from uncle nerd out PLEASE!! :) thanks for the cool vid!! Also im an Escooter guy but this is all still relevant- MICRO MOBILE BROTHERHOOD ROLL OUT!!
Exactly! Could use some tutoring on this as well
Can you hook it up to the battery charger and use it while riding your bike ? Or are able to make that ?
thinking of making a mopped scooter 72v a reliable high speed electric solution for a trip i think !!!!! my idea .. 48v bank from small 15 amp headaway solenoid LFP for ups attached to a 48v solar charger when clouds.. directly to 2x light movable 24v solar panels and then a high voltage boost converter50(v to 90v you adjust the amps until the bms of the ups pack shows zero in zero out and you have some spare energy if need it too... and is going to be lighter than an eco flow !!!!!! dc to dc magic!!!!!! and you never go ac ,,, if need you have spare fuses and another converter for backup they are super light
If you had 2 solar panels wired in series or parallel? then you'd double your amperage output to the battery and charge twice as fast, correct? I got my mppt charger connected to a 100 watt Sunpower panel and it appears to be charging very slowly, so I'm going to try to get another panel exactly the same for faster charging. My panel is flexible and weighs 2.5 pounds and is fairly flexible. Thanks in advance for your reply, you're very quick with responses and it's appreciated.
Great job mate! Can't wait to try it out for myself for the 'long-haul'.
Do you accept paypal and ship to Australia? I've been looking for a solar charger for my scooter 67.2V up to 8 Amp LG battery. I think they are lithium ion not LiFeP04.
yup my kind of crowd , if your ebike battery has 20A charging at avr. half of a amp it will take up to 40 hour to fully charge ,so break it down to 6 hrs a day charging that would take around 5 days for 1 full charge to happen
example, i rather use my car to charge it when I go to work with that buck converter , I can charge up to 10A in the cigarette port and fully charge it in two day or less , so thats 2 hours of total charging
Is the battery BMS stopping the load when is fully charged?
Thanks once I see it can be done do it once then rig it my way , worst is when moped battery dies and crank never work
I plan on bugging out of p town with a 48 volt 2000 watt e-bike and trailer with hot tent stove and bushcraft tools.
Sounds sort of similar to the plot of the original Rambo film.
@@JohnnyNerdOut Seriously the city is dead I got computers and E-bikes what else can I do?
TNR
@HoboGardenerBen I think I need a truck I can't get the load light enough.
@HoboGardenerBen I picked up a survival garden for 20 bucks that would be nice to plant this spring.
There's another guy who builds solar e-Bikes and if I understood him correctly his set up is similar to yours but he appears to be using/draining his battery while simultaneously charging his battery by connecting to the onboard solar panels he trailers behind him. Of course he's not using all battery power to power his bike. He's using a certain percentage of peddle power in combination with battery power. This allows him to ride long distances while maintaining his onboard e-Bike battery at a high level of charge.
I mention all of this to ask; does your battery have the ability to be used in this way if you were to be hauling around a couple of solar panels given the electrical connections you've made? I mean, actually using power directly from your battery while at the same time charging it if you were to ride with a trailer of some kind to haul your solar panel around; and if you were offsetting the battery depletion by using a certain percent of peddle power as well?
I'm just wondering if all e-Bike batteries have the capacity to be charged while simultaneously being depleted.
Yes they do! Following up video is scheduled to be put out very soon!
@@JohnnyNerdOut Thanks. I'll keep an eye out for it. It may be helpful in setting up my electrical components.
I'm about to take 300 watt foldable solar on a 600 mile tour.
let us know how it goes!!
Thanks bro. This is what I needed to see🙂👍. Yeah, I want me Some Free range WATz
Hi, can I use the same system but with a 12V leisure battery replacing the solar panel to charge my 48V 13S 5P lithium ebike batteries. I have just built 2 bafang BBS02 powered bikes as per your videos - Awesome!!!
I have already fitted 2 X 130W solar panels to my motorhome that charge the leisure battery from a MPPT solar charge controller.
There doesn't seem to be much info about, on this simple system you show, everyone else seems to promote introducing inverters to power the mains charger and over complicate the setup. As my motorhome system has already efficiently harnessed the power, seems to be an efficient way to convert to the right voltage and with current limit set too.
All these terms, good stuff ty
I charge an almost empty 500Wh Bosch battery with a 144W Bosch charger within about 4.5 hours. With your 20W solar device this would take you several days.
Use a hockey puck to adjust your panel. No shadow from the puck means you are in alignment.
I'll try that
is this battery on a Super73? Any risk of overcharging? Don't you need a charge controller? Anybody know if the Super73 which allow fast charge at 48v @ 5a, have a built in BMS and Charge controller?
Make a video and show us exactly how you built th ih s ? And what the essentials are ?
What about amps? My battery pack looks just like that it's a 48 volt 2A and my charger blew during Ida
Great video 👍🏼 " You can Charge you Ebike battery for ever " For charge my battery it will take for ever literally 😂 Because is 48v 24A. I think maybe 2 days, any way good video I waiting to see more updates in your solar charger setup 💪🏼
Ya, it's definitely not a fast charger. But it could add a "quarter tank" a day with your setup. I'll have to see if adding solar panels adds more output Watts, or if it just overheats and blows up🧐
@@JohnnyNerdOut Instead of just using a straight converter - why don't you look at the solar MPPT charge controllers you can get for cheap off of ebay? They get great efficiencies and they control the charging for you. All you have to do is set the output (battery) voltage, and plug it in. Just search for "mppt boost charge controller" on ebay and you'll see what I mean. Can be had for
@@Demdere thanks I will!
Just ordered one👍
Is there a way to control amp output? Like besides just adding a fuse lol.
Do they get that stepped up boost up solar charge controller thing redo it on Amazon to
But: can I charge my ebike off my vehicle while driving to my destination??? You can charge your flashlight, radio, and cell phone so why not an ebike??
Yes you can
i have 48v battery in silverfish case, do i need to adjust the control device to 48v? in order to charge my battery!?
Yes
What size is your ebike battery? And what watts are the panels? Thanks
52v 17.5ah. 100w
im doing it all wrong going from dc to ac and back to DC. A little difficult to find 75V boosters, You might want to add panels to get the amps up, I need at least 5A at 76v for 2 hours to fully charge my RCR's 23Ah battery from half full.
Ya it's not ideal to switch back and forth due to efficiency loss. I'll post an update soon now that I have more panels.
you should tell people how you wired the reader in. Pretty critical information that can't be traced through tbe shadows and electrical tape in the video.
I’ll be making a new version of this with my solar boat setup. Stay tuned.
I built 1 e-bike from a treadmill motor. It would only do about 25 miles an hour. I put two Motors on a bike with 2 48 volt batteries and it does 40. I don't understand how you can step up voltage?
Converters! There is some loss in efficiency when doing it though. Sounds like a pretty cool build!
Nice set up. I have ordered the same voltage booster as your. Did you set the second potentiometer for the current? How do you increase the current, counterclockwise or clockwise?
Can’t remember off hand! Using a voltmeter and ammeter you can find out real quick
Hi looking to do this in UK for my 36v ebike I have a trailer and couple of batteries so want to have a battery charging while riding sollar panel on trailer all day, I've found step up converter and a new panel but the meter you have I can't find on amazon, what's it called ? Also what wire do you recommend my max charging will be 42v, look forward to you reply, Mike.
google "ammeter", should come up? 12g or even 14g is fine for 42v
I’d like to X5 your set up Johnny 🥳🥳 ie solar trailer thingy using flexible panels , and I still haven’t found a good place to get my bbshd in Britain ……they only want to sell me a compleat bike aaarrrggg
Out of stock...but anyways can't this hurt your battery due to not being original charger or not having the correct stats?
Only if you over charge it
You can't tell when you're battery is fully charged though.
Can you put those panels on a tripod to direct it more to the sun. Maybe even use a solar tracker
Yes!
Buy a 300 watt jackery add pannels
It'd be really cool if it was small enough to fit and maybe a pack for a cross country ride
They are available
How long did it take to charge to 54 volts and how many volts did you start with? Really like the concept though.
It’s better to use watts and watt hours. Consider you might get 60 wh from a 100w panel. Depends on your battery but 10-15 hours for a big pack
how long does it take to fully charged the battery?
At .75 amps a 52v 10ah battery would take about 13 hours. So not super quick.
my charger need at least 535Watto fo power with 100-150Volts an 4 hours, not possible to use solar direclty and buffer batteries are also needed a lot of.
my batztery cannot be charged withoout the computer in the charger to start charge, nothing is measured on the output pins too until the charger send data, it is too clever
Organic, aren't you the comedian. 👍✌🖖🥃 Isn't everything free after we pay for it? 🤣
Could you use a 12 vote inverter , that would take the 12 v from battary and change that to Ac, then take your bike plugin charge and plug that into the inverter to charge the 36 vote bike battary, would that work.
Yes
@@JohnnyNerdOut thank you for the reply, this was my plan. Take a 100 watt q2vote solar panel and run it to a 12v battary then to a 1000 watt Ac inverter, then plug in my Ac wall charger plug in to the invert, to charge my 36 V 8 amp battary for my bike. Would that still be a yes and not sure what size 12V battary to use.
.40 amps? that would take a week to fully charge an E-bike Battery..
A better panel and a better sun pattern could get close to 4-5a
It will pay for its self very cool
"Bucks" stop here. Look at what types of circuits and components is in a typical charger the two types of charge controller MPPT vs PNW. Charging the BMSed battery to run the motor is a via. A smart switch that the RV and Van guys use will simply use panel if and when it is suffient for loads and draw rates. All this stuff kinda adds up and beyond the "E bicycle" constraints for now.... Adding a management computer to "if then" "if when" and setting limits and triggers. Your channel does encourage "nerd out"
I see a consult potential in future. Off grid mostly in Colorado until return to AZ and my workshop.
Why not just a boost charge controller there only about 40$. Much more easy to use and has all the meters built in and diffently more safe for the battery and yourself
I just got my first MPPT!
You're brillant young sir
TC 1:31 Does 'here' have a name ?
Hella cool!
If you got a 72v battery would you just need more solar panels and a different voltage monitor?
I would need a different step up converter, this one only goes up to 60v
@@JohnnyNerdOut how long does it take to charge your battery In a cloudy day? I wanna ride my bike 14000 miles haha
@@jacobm9574 a very long time. Sometimes if it's very cloudy, my panels don't pickup anything at all. A different panel could solve that though.
So how long did it take to charge the empty battery cell with the Solar Panels ?
Depends on sun. Best case scenario is a day.
@@JohnnyNerdOut Not bad, iv been wanting to do a long mountain hike with a E bike. Was wondering about solar panels to refill the bike. Thanks for the info.
Wow. Unadulterated watts from the solar collector!. I’m going to eliminate all the contaminated watts from my life. Where can I dump all those dirty watts I need to get rid of?
You should have a free range sanctuary nearby you can bring your dirty/ neglected/ abused watts where they will be cared for and hopefully re-abilitated :)
Time to build a solar ebike trailer
Like one attached to both side or the axles like a cargo trailer with 1 wheel or like a burly trailer or something like that and a boost controller for infinite range
Thats nice but half of an amp would take 48 hours of sun to charge my 24ah battery. Is there a way to get more amps?
More sun or more panels
@@JohnnyNerdOut I just saw an Andy Kirby video. And he used a Victron controller 100/20 (I believe) with a 330 watt panel and looked like he was getting between 2-4 amps. Worth a look. Thank you for getting back to me. I'm new to this and I'm greatful for all advice!
It may be that bikes can be recharged to some extent whilst riding using a flywheel system. That is whilst we pedal there is both a sproket and a fly wheel, that has magnetic interface so it spins fast enough to run a small generator that we had to run lights, we can put in to the system or battery, If there are two batteries,using the above, one to run on one to recharge one wonders if this could not resolve the question. Given the brilliance of Americans I suspect that can be done.
@@taooflovepassionandcomedy8722 so, like a perpetual motion machine?? Sounds good to me!
65$, so like 50 + full charges till you get those green power units tho?
20 watts....or 0.4 Amps ????
If my 14.5 A battery is ONLY HALF discharged...your set-up will fully re-charge it in...????
SEVENTEEN HOURS !!! or TWO DAYS of sunlight.....GREAT, good to know
I have recharged my battery using the solar system in my RV, a combination of rooftop and deployable panels....it's doable but it's slow....the ability to aim the panels perfectly to the sun will GREATLY increase performance (in my tests a perfectly angled panel produces roughly TWICE the power than one laying flat). Doing it from an RV's solar system is real simple: you can use a cheap/inexpensive inverter (100 to 150W) and just plug/use your supplied bike charger.
LOL ya, this was in winter sun too. Might be more efficient using a MMPT controller. test to come....
@@JohnnyNerdOut Face it! The dream of recharging your e-bike battery while on the road with your e-bike alone... towing a trailer to carry all your camping gear and panels would translate, in the real world, as traveling every other day with the day in between devoted to charging, constantly moving the panels to keep them perfectly aligned to the sun.
The sun might be free but it's stingy.
They should make a solar power backpack for like $200 that plugs into your bike
There is one at Canadian Prepper, but it is over $400.
Organic, free range, premium watts. Give me a break.
No preservatives either
how do you know when the battery if full ?
Check the display
LOL! Organic Free Range Watts!
Just me, personally, I would keep the BATTERY completely out of the sunshine.
Absolutely, this was for the presentation
✔I kind'a figured ....
It’s cool but it’s warm 🥳🥳🥳
The people who charge their e bikes and cars from a 120 volt AC outlet are just kidding themselves. Some watts had to be "adulertrated" in order to charge that free energy car!!!!
I hope everyone understands your implications.
😂
Organic free range watts! None of those caged watts.
That's ingenious and ridiculous.
that will damage the battery pack
