There is a video of a guy that replaced the stock batteries with 15 amp hour 36-volt batteries and then put another set of 15 amp-hour 36 volt batteries in his basket. He then wired in a toggle switch and can use the same charging cable and port by simply just switching from one set of batteries to the other. This gives him 30 amp hours which is over 4 times the distance the original battery configuration gets. You could still tow your trailer with a solar panel on it and charge the batteries anywhere you go. Thanks
It's a helpful video, thanks. I hope to purchase this scooter or an electric tricycle and to give its ride longevity by utilizing a solar power station on board. I have the idea to attach a bicycle shade/rain canopy to one of these EV's and place lightweight folding solar panels, like hikers can wear on their backpacks, to the top of the canopy. The bike would be plugged into the solar power station along w/the cords to the small solar panels; have you tried that yet? I would definitely put another basket on the very front of the EV. I'd also like to build a camper to tow behind my EV, but I haven't figured out how to do that yet - I'm not handy like that.
Look at teardrop trailer designs! Some people have made tiny ones to tow behind a motorcycle: Sleeps one person, but it also serves as storage space for your camping/cooking stuff.
Just get bigger batteries, or carry a second pack to swap in. You are losing a lot by converting it twice, not to mention the added weight. Also can get Lithium batteries to save a lot of weight and longer life. Its mostly a matter of cost as to what solution is best. Solar to recharge is fine if you have the time and no other option, but you will be charging most of the day and riding at night.
How has the battery reserve been working out? Can you fully recharge your 7aH batteries off the one 35aH battery? Anything you would do differently now? Do you have to buy additional equipment to charge your reserve battery off a standard 110v outlet?
It's me again, just here to pick your brain a little more. So here's where we stand, bought 3 - 12 volt 15 amp battery's to replace the 3 -12 volt 7 amp battery's that are presently in the scooter. This should increase my range to almost double, a little less is okay. I've even gone a step further in my camping dreams future by buying a 250 watt solar generator, with a companion 100 watt solar panel, but to top off the tank even further I'm considering adding that 12 volt 35 amp battery for back up. My problem is this, HOW NOW BROWN COW !!!!!!!!!!!, I'm totally lost as to how to arrange everything, Ha ! Ha!.
I like your ambition and I went with the "increased Amp hour strategy" buying additional SLA batteries and swapping out.. however.. the increased weight of the higher Amp SLA batteries, barely made a difference in speed and battery life.. if you really want to wake your Eco Metro up, go with Lithium replacements. Dakota makes a 12V 10 Amp battery for about $99 a piece. You will need 3 of them... A $330 ($30 wire harness) investment can increase speed by 5+ MPH and 3+ hr. runtime.
incorrect on the 21 amp hours since the batteries are 12 volt wired to 36 volts that increases the voltage. the amp hours stay the original 7. great idea with the battery-inverter-solar panel. thanks for your videos on this scooter! i've seen some where that you can fit the 12 amp batteries instead of the 7 amp ones? and since the 15 amp ones are about the same size.... wonder if they would fit? i'm thinking of ordering one of these and may apply some solar to it using a couple of the thin light weight flexible 50 watt panels and use the "power with out battery" deal that missouri wind and solar sells. that is essentially a charge controller and inverter in one unit that you could directly power the battery charger with and skip having the extra battery. *should work* lol. thanks again for your videos. appreciate it!
Loring Chien, Electrical engineer Answered Jul 6, 2015 · Author has 30.4k answers and 53.6m answer views A battery is a two terminal device which means that there is one current through the device. The Current is defined as charging if the value is net positive so it flows into the positive terminal. If the current is net negative it is discharging and the current flows out of the battery. If the current is positive it is charging, if it is negative it is discharging. Its that simple. If you have a three-way junction node between a charger, a battery and a load, then the sum of currents into the node must be zero. That is: I Charger + I battery + I Load =0 If the charger provides -1.5 Amp (out of the source) and the load takes +1.0 Amp in then the battery must be taking +0.5 A, since its positive its charging. The sum of the currents is zero.

Dave Martindale, Electronics hobbyist since 1965 or so. Answered Feb 16, 2019 · Author has 2.3k answers and 1.4m answer views As several other good answers have said, the battery is a two-terminal device, and at any instant in time is can be charging or discharging but not both. However, it is possible for the battery to switch rapidly between charge and discharge at a high rate. For example, suppose you have a near-discharged battery in your car which will no longer start the car. To fix this, you connect an AC-powered 12 V lead-acid battery charger to your car’s battery and plug it in. Now the charger is charging the battery - but only some of the time. This particular style of car battery charger has a transformer which steps down line voltage to something like 16 volts peak, then full-wave rectifies the transformer output and feeds it directly to the battery. The output of the rectifier is a periodic waveform (basically the absolute value of a sine wave) with 120 peaks per second (100 in Europe). There is no voltage regulation, not even a capacitor to smooth the waveform in the charger. When the charging voltage is higher than the battery voltage, current flows into the battery and it is charged - for a few milliseconds. Then the charging voltage drops, and the diodes in the rectifier prevent current flowing from the battery back through the transformer - until the voltage rises on the next half-cycle. This pattern repeats 120 times per second, 8.3 milliseconds per cycle. So the battery charges for 2 or 4 or 6 ms (depending on voltage) and rests the remainder of the time. Now, suppose you left the door of the car open and the dome light is turned on. During the few milliseconds that the charger voltage is higher than the battery, the charger is supplying the current needed by the bulb as well as charging the battery. But for the rest of each 1/120 sec cycle, the battery is supplying power to the bulb. So the battery is now switching between charge and discharge 120 times per second. So: If you look at a period of time 1 second long, or even 1/120 s long, the battery is both charging and discharging within that period. But at any instant in time, it’s doing one or the other only.
there is no way i see it working....because lets say you reach the maybe 5-6 miles at lowest speed with no hills to reach those miles then the half ways mark your done and have to charge the scooter fully to get another 5-6 miles, I mean come on it already takes super long to charge the batteries fully to get those regular 5-6 miles so charging it solar you would wait forever then to have to get there and batteries are done then you have to charge it again forever to go back hom for those 5-6 miles back and again you have to charge it one more time to get home like come on that is not realistic or efficient. I suggest you save all the money for the panels for the inverter for all that you used and just buy the ebke battery packs and convert the lead acid crappy battery into a long range light weight 1860 battery or lithium battery pack with a BMS and that is it no need to waste time and money and this battery would give you 25-30 miles range without one time charging it perhaps even more for the price you payed for all that...since you can fill the compartment with a big battery of those instead of those lead acid heavy wasteful batteries it comes with. I know because I done it, i first started with a small version pack that blows away those lead acid ones inside ...i got way longer range and its the size or one of the batteries inside so it had tons of more space to use an even bigger battery.
Just another couple quick questions, can you charge and operate at the same time, so that you have a continual flow without draining the battery's all the way down, or is that bad for the battery's. Now I know we can operate the generator and supply solar watt's while it's charging. I'm considering a more direct connection from solar panel to battery bank, like the generator which is really just a bank with terminal connections for other use's. I already have the 3-12 volt 7 amp battery's, but I think there is a problem with mixing the two, that is 7 amp with 15 amp for charging, but as a bank I'm wondering if it's worth the trouble to add them or not, what are your thoughts, thanks again.
@@YagwitOG When people use a solar panel that is charging a system/bank of battery's, they are able to use the bank while the panel is charging right? So why isn't it the same?. If I had a solar panel charging my battery bank as it is discharging to operate other systems?, or in this case my scooter motor. Thank you for sharing.
@@ambroseabellair5306 Did you ever figure this out? My scooter is arriving today, and I have small deep cycle batteries and an inverter already. But… Isn’t there a way to rig a “switch” that just connects to an external 12V battery, instead of using the external battery to charge the internal?
@@Ira88881 First of all, the motor is a 36 volt, so without a booster that will step up the 12 volt to either 24 or 36, you can't tie a 12 volt directly to it, even if you had a switch. Secondly which way are we inverting, from ac to dc or from dc to ac. If your referring to a typical solar panel inverter that runs from the solar panel to the 12 volt battery to a inverter that allows you to plug in ac appliance's, then no, because your turning it back into ac. If you are however speaking of a ac to dc inverter, you will still have to use the booster that will increase the dc out put to match the 36 volt motor and then, according to people I have spoken to, it's no different then talking on our phones while there being charged. So yes, if under those circumstances / 36 volt booster, not only can you do it, but you don't even need a on off switch, because you will actually be re-charging it, while it is operating, just like our phones, but you need to make sure your spliced into the right wires and that is as far as I have taken it. I do not have any personal experience other then what I have learned from others, and I have not done it to my own scooter. If you get it figured out and actually set it up, please contact me back through this comment to let me know how it went for you, but that's what I know, and as of yet I have not done it myself. The deal about the phone made sense to me, that if we can charge our phones at the same time we use them, then the technology is the same for these battery operated scooter's. What we CAN'T DO, is try to operate it, as we are charging it through the ac charger plug on the scooter, it must be wired internally from the battery / battery's, to the battery's. I have another set of 3 -12 volt battery's that I was going to try to connect to the internal wiring of the 3 that are already in the scooter. It comes with 3 - 7 amp, 12 volt battery's wired together to make 36 volts, because the motor is a 500 watt, 36 volt. I replaced the original 3 with 3 that were 12 amp, and almost doubled my distance. Remember amperage is for distance, voltage for speed. I hope your successful, there's no reason to believe that it can't or won't work. The other question is, will they all charge together through the already built in charging plug, or do we need to use separate charging ports. Sometimes the charger will sense the first 3 as being full, and not continue to charge the other 3. Good luck and thank you for replying.
@@ambroseabellair5306 Thanks for the detailed reply. I since realized that I have either a 36 or 48 lithium battery, a brand-new spare that I bought for a mobility scooter. (I have to check the specs. I’m not home now.) This battery was a fortune. 500 bucks. If this is the case, do you think there’s an adapter, a harness, a plug and play solution…which connects to the charging port of the scooter and I connect the additional battery and charge both simultaneously?
😂 there is energy transfer, when this happens you loose energy, therefore you are loosing more energy than you are using. Maybe! Have a solar panel charging a 36v extra battery or like drill batteries in series too, and then have them connected via a toggle switch to activate when need it, what do u think 😅
Nice idea, but I have the same scooter and I found that you can replace the 3- 7 amp battery;s that come with it with 3 - 15 amp battery's and they will still fit in the same compartment, just have to rearrange it a bit and remove the plastic cover. Also with doubling the mileage, from battery replacement which will run you about 100 bucks, you then have the 3-7 amp battery's available to put in your basket of which can be connected directly to a secondary on off switch so there is no recharge waiting time which you kind of forgot to mention. So basically you can increase the over all mileage to about 20 to 24 miles without any time loss, simply by adding switching the battery's you have with 15 amp one's. Now if for camping purpose's you want to bring along the solar panels and extra battery bank, I'd actually go for a 36 volt 72 amp led acid battery. It's a lot cheaper and can also be connected directly to the the same on off switch already added, or add a toggle switch and the wiring can be run to your cargo carrier, which could be set up to charge as you ride. Sticking to the 36 volt system already set up for the scooter is always a good idea and you lose much, much less in not having to invert from ac to dc or dc to ac. Really liked the thinking behind your video, and there is always room for improvement. Hope my suggestion has some appeal to you as did yours for me, thank you.
I'm living in Arizona, so we have a ton of sun light almost year round. What I want to do is to convert and or add onto what I have, by building up off of my razor eco-smart, with a solar panel roof for shade above me and add a small trailer with a solar panel for a cover on it as well. I'm asking a lot, so if you chose not to get involved I'll understand or you think a bit of a consultant fee would be inline, then lets talk. The basic's is all I really need, I'm mechanically inclined, but don't understand power wattage's etc, etc, etc. I' m not to good with this solar panel configuration whole electronic's thing, so I really don't know what wattage of size of panels I would need to operate the motor, bypassing the battery's and or charging them as the need calls for. On a shady day / rainy day, I'll have a little cover from the panel above me, but will want to run my battery's, so a toggle switch to control direct solar power back to battery, is what I'm looking to do. I'll have extra room for carrying things in the cargo carrier, and will want to put a panel on top of it as well. So what size panels would I need, wattage / voltage to run directly from the solar panels to the motor, to operate purely from the solar panel, and or connector's step up electronic or what ever to implement and operate the system I'm speaking of etc, etc. Like that little converter thing, or some other sort of go between that needs to be installed, all of that electronic stuff goes right over my head. If I had to go to a solar panel shop, I doubt that they would work with me without charging me a arm and a leg, or expect me to buy the equipment at a higher cost from them rather then to try and go direct to the manufacture. So if you could pass on the basic of how to hook a system like that up and maybe do a video on it for everyone else to learn from, that would be great. It's small bug out / week end camper hook up, I'm gonna get a tent, fix the cargo trailer to open up into a bed etc, etc,. So I might even go the way you talking about on this video and still add the panels, not like the camper panels I want permanent one's for the shade. really looking to bling it up, stereo speaker's, etc, etc, light's for night time, not riding but for the camping. Really thinking out of the box, a bit bigger project, but the sky's the limit, one panel at a time Ha! Ha!, thanks for listening even if you aren't able to help.
Your right, it took a few other video's and a little searching, but what you have said is what I hope to do. Just looking to extend my power supply for a week end camping etc, etc, etc. Some might not think this scooter is up to the job and as far as getting to where I want to camp, I might have to use alternative transportation, but once I get there, it's me, my scoot and the solar panel's, thanks
...IN TIME ...AS YOU CHARGE ALL THREE BATTERIES AT-ONCE THEY WILL BECOME UNBALANCED. THIS IS WHY THE BATTERIES WEAR OUT SOONER. ..CHARGING EACH BATTERY SEPARATE WILL EXTEND THE LIFE OF EACH BATTERY. ...YES IT'S A PAIN BUT ...CAN BE DONE WITH SIMPLE SWITCHES. YOU WILL NEED 3 ...12 VOLT 2 AMP CHARGES ...THEY ARE REALLY CHEAP! ...OR JUST USE ONE CHARGER ...BUT IT WILL TAKE LONGER TO CHARGE 1 BATTERY AT A TIME. ...AGAIN ONCE YOU THINK ABOUT IT ... INSTALLING THE SIMPLE SWITCHES IS A ONE-TIME INSTALL! ...$2O BUCKS OR LESS TOTAL! ... YOU CAN SAVE YOUR BATTERIES LIFE ...OR PAY THE MAN!!
Thank you. I'm thinking of getting this scooter because I am tired from having cancer 8xs. I live in a van and everything I have is solar and this would work well for me. Thank you.
Thanks, I need my scooter to go at least 10 miles round trip, and I think your solution is going to work just fine !

I hope your successful, there's no reason to believe that it can't or won't work. The other question is, will they all charge together through the already built in charging plug, or do we need to use separate charging ports. Sometimes the charger will sense the first 3 as being full, and not continue to charge the other 3. Good luck and thank you for replying.
@@ambroseabellair5306 Thanks for the detailed reply.
I since realized that I have either a 36 or 48 lithium battery, a brand-new spare that I bought for a mobility scooter. (I have to check the specs. I’m not home now.) This battery was a fortune. 500 bucks.
If this is the case, do you think there’s an adapter, a harness, a plug and play solution…which connects to the charging port of the scooter and I connect the additional battery and charge both simultaneously?
😂 there is energy transfer, when this happens you loose energy, therefore you are loosing more energy than you are using. Maybe! Have a solar panel charging a 36v extra battery or like drill batteries in series too, and then have them connected via a toggle switch to activate when need it, what do u think 😅
Why use an inverter to convert DC to AC and then back to DC? Isn't there a direct DC to DC connection?
Nice idea, but I have the same scooter and I found that you can replace the 3- 7 amp battery;s that come with it with 3 - 15 amp battery's and they will still fit in the same compartment, just have to rearrange it a bit and remove the plastic cover.
Also with doubling the mileage, from battery replacement which will run you about 100 bucks, you then have the 3-7 amp battery's available to put in your basket of which can be connected directly to a secondary on off switch so there is no recharge waiting time which you kind of forgot to mention.
So basically you can increase the over all mileage to about 20 to 24 miles without any time loss, simply by adding switching the battery's you have with 15 amp one's. Now if for camping purpose's you want to bring along the solar panels and extra battery bank, I'd actually go for a 36 volt 72 amp led acid battery.
It's a lot cheaper and can also be connected directly to the the same on off switch already added, or add a toggle switch and the wiring can be run to your cargo carrier, which could be set up to charge as you ride.
Sticking to the 36 volt system already set up for the scooter is always a good idea and you lose much, much less in not having to invert from ac to dc or dc to ac. Really liked the thinking behind your video, and there is always room for improvement. Hope my suggestion has some appeal to you as did yours for me, thank you.
I'm living in Arizona, so we have a ton of sun light almost year round. What I want to do is to convert and or add onto what I have, by building up off of my razor eco-smart, with a solar panel roof for shade above me and add a small trailer with a solar panel for a cover on it as well. I'm asking a lot, so if you chose not to get involved I'll understand or you think a bit of a consultant fee would be inline, then lets talk. The basic's is all I really need, I'm mechanically inclined, but don't understand power wattage's etc, etc, etc.
I' m not to good with this solar panel configuration whole electronic's thing, so I really don't know what wattage of size of panels I would need to operate the motor, bypassing the battery's and or charging them as the need calls for. On a shady day / rainy day, I'll have a little cover from the panel above me, but will want to run my battery's, so a toggle switch to control direct solar power back to battery, is what I'm looking to do. I'll have extra room for carrying things in the cargo carrier, and will want to put a panel on top of it as well.
So what size panels would I need, wattage / voltage to run directly from the solar panels to the motor, to operate purely from the solar panel, and or connector's step up electronic or what ever to implement and operate the system I'm speaking of etc, etc. Like that little converter thing, or some other sort of go between that needs to be installed, all of that electronic stuff goes right over my head. If I had to go to a solar panel shop, I doubt that they would work with me without charging me a arm and a leg, or expect me to buy the equipment at a higher cost from them rather then to try and go direct to the manufacture.
So if you could pass on the basic of how to hook a system like that up and maybe do a video on it for everyone else to learn from, that would be great. It's small bug out / week end camper hook up, I'm gonna get a tent, fix the cargo trailer to open up into a bed etc, etc,. So I might even go the way you talking about on this video and still add the panels, not like the camper panels I want permanent one's for the shade. really looking to bling it up, stereo speaker's, etc, etc, light's for night time, not riding but for the camping. Really thinking out of the box, a bit bigger project, but the sky's the limit, one panel at a time Ha! Ha!, thanks for listening even if you aren't able to help.
Your right, it took a few other video's and a little searching, but what you have said is what I hope to do. Just looking to extend my power supply for a week end camping etc, etc, etc.
Some might not think this scooter is up to the job and as far as getting to where I want to camp, I might have to use alternative transportation, but once I get there, it's me, my scoot and the solar panel's, thanks
? 400 watt inverter for a 500 watt motor, not sure u will get full power
It's enough. The inverter slowly charges the battery, not powering the motor directly. Go read some books.
...IN TIME ...AS YOU CHARGE ALL THREE BATTERIES AT-ONCE THEY WILL BECOME UNBALANCED.
THIS IS WHY THE BATTERIES WEAR OUT SOONER. ..CHARGING EACH BATTERY SEPARATE WILL EXTEND
THE LIFE OF EACH BATTERY. ...YES IT'S A PAIN BUT ...CAN BE DONE WITH SIMPLE SWITCHES.
YOU WILL NEED 3 ...12 VOLT 2 AMP CHARGES ...THEY ARE REALLY CHEAP! ...OR JUST USE ONE CHARGER ...BUT IT WILL TAKE LONGER TO CHARGE 1 BATTERY AT A TIME.
...AGAIN ONCE YOU THINK ABOUT IT ... INSTALLING THE SIMPLE SWITCHES IS A ONE-TIME INSTALL!
...$2O BUCKS OR LESS TOTAL! ... YOU CAN SAVE YOUR BATTERIES LIFE ...OR PAY THE MAN!!
Worthless unless you can change while driving.
Thank you. I'm thinking of getting this scooter because I am tired from having cancer 8xs. I live in a van and everything I have is solar and this would work well for me. Thank you.
