I have done some testing on my 60v 800watt motor. In real life with load (weight), inside a smaller ev, 800w is low end, lowest gear on a plain and flat surface. The throttle only at 50-70%. In third gear at max throttle, 20miles/h 29km/h, on same surface it will wobble around 1200watt to 1600watt. This is what degrade many gel ebike batteries. They are not build for this high drain.
On a slight mild slope in third gear it will climb to 25-35amp and a mild slope or higher will put it on factory maximum of 40,5amp or circa 2500watt depending on voltage 66-69v.
I replaced my gels with 32650 LiFePo that is build to handle it and now its both faster, more responsive and charge faster. I charge those with solar.
Edit: forgot to say thanks for the video. :)
Hi friend,
Thanks a lot for the great feedback!
We appreciate it.
It's always great to hear the experience of someone who has already built and tested a system.
👍👍
I agree with you that we need to account for the surge conditions. As a matter of fact, I started the testing with my sealed LA batteries, but I quickly realized that they are not able to support the current surge. Luckily, I have a few 32650 Lipo4 battery packs that I was able to use for the testing.
Thanks again for the wonderful feedback.
Making the video took a great deal of time, but I was super excited and happy to do it.
👍😎
Good information
The lead acid batteries suck at high discharge rates, they can provide high curtent very brieffily but they will drop down very early
@@felipehcraftgamer4193
I fully agree.
👍
I use boost converters on my Bikes. Just gotta make sure it is rated properly for the Motor and the controller. Surprisingly, it is not common to find 48v high power output boost converters. It took me a while to find one.
Wonderful!
Thanks a lot for the amazing feedback.
I am glad you found one that worked for you. Do you mind sharing the link to the boost converter?
I would like to get one myself and test it.
👍😎
What I like about your video is now I want to try to make the biggest battery bank on my bike and add that inline to compensate for the rest of the voltage, KEEP-ON KEEPIN-ON 😁👍
Thank you so much for the wonderful feedback! We appreciate it.
👍😎
If youre using a lot of cells to make a large battery you can choose the volts so youll know how much is gonna come out.
It definitely works. Buy using boost convector will lower down the battery mileage charges than actual.
Yes, you are correct. Boost converters will introduce efficiency losses that will lower battery life.
The point is that some people may find themselves in situations where they can not afford higher voltage batteries, and they are willing to sacrifice the reduced mileage for a cheaper alternative.
Low Budget Dilemma:
Do I spend $200 more for a higher voltage/bigger battery, or should I just buy a $30 boost converter and sacrifice some mileage?
Personally, I don't recommend the boost converter option for those who can afford bigger batteries.
Amazing❤
Thanks again for the wonderful feedback.
👍
Amazing
Thanks!
weve run the 40 amp version with a 36volt and 48 volt battery and boosted it to 84 volts as long as we were easy on the trottle it ran quite well
Wonderful!
I am happy for your success!

I’ve just ordered the 1500w version of this step up converter to boost my e-bike voltage from 52v(58.8v) up to 72(84v)*maybe above as it allows up to 97v…* it says I should upgrade the cooling for above 22A so I’ve also picked up a twin pack of 50mm fans. The max amps on the one I ordered states 30-35A so do you think I would be ok to pull 30A for short periods of time, maybe 5-10 seconds at a time with 10-15A most of the time? My main intention is to aim for speed at the cost of torque and obviously efficiency.
Wonderful!👍👍👍
At such a high input voltage, I believe you should be good to go, but that is my informed opinion.😊 You still need to test it to see how the converter will perform.
Success wishes!❤️

Nice and very informations,
Which motor better for generator, brush,or brushless motor?
I would prefer the brushless motors because you won't have to worry about replacing carbon brushes every now and then.
So is it the Electronic Speed Controller that is used to control the power to the motor? and the Boost Converter is just outputting the maximum power it can?
That is absolutely correct.
The motor speed controller uses PWM to control the power delivered to the motor.

Hello from Canada.thank you for all your videos.I have a two 24 volt 25 ah reongy lifepo4 battery.which can only be run in parallel not series or I’d have my 48 volts.
I am looking for a dc to dc booster to turn my 24 v to 48 v.
from there it feeds into a 48 volt brushless controller.model# 4t48zwsrm-gh04q.
rated current 9a,maximum current 18+1a,speed limit 1-4.2v,brake input:low level,low voltage protection 40v+0.5v.
From there feeds into bafang 48 v 500watt hub motor.
Can you or your viewers please recommend a boost converter to Change battery from 24v to 48 v and that will work safely with the controller and motor.
I am doing my best to figure it out myself but my brain and math/numbers don’t work so well together.
My fear is damaging my controller/motor using the wrong converter or it not working properly.
I have a bpm imports fat tire trike 500 watt 48 volt.
You can not find these trikes in 500 watt because bpm Canada never got off the ground due to Covid.
The USA versions come in 750watt and up.
Thank you again for all your great videos.
Happy Monday to ya.
Hi friend,
Thanks a lot for watching our videos and for leaving great feedback.
Regarding converter recommendations, there are lots of dc to dc boost converters out there that could meet your needs. It really depends on your budget.
The converters shown in this video in theory should be able to individually give you the power you need at a 48V output with an input voltage of 24V. The rated current limit is about 30A, so at an input power of 24V, you should be expecting about 720W to be processed at the input of each converter.
However, the output power has to really account for the efficiency of the converter system at 24V input.
Assuming a worse-case efficiency of 80% (it should really be better than this),
The available delivered power at the output = 720 X 0.8 = 576W.
Hence, if my theoretical calculations are correct, and your motor doesn't care too much about ripple noise levels,.....then one of these $30 converters should give you what you are looking for.
VERY IMPORTANT NOTES:
1. Make sure that the UVP is set to below 18V.
2. Ensure that the constant current potentiometer is set to the Max output current position.
I will recommend you take some time to watch all the videos below and I am confident that they will answer any further questions that you may have regarding these converters. Just an FYI, I am not affiliated with either the vendors or the manufacturer of these converters. My reviews are based on my personal ho est opinion.

ЗДРАВСТВУЙТЕ! Привет из Чернигова 🎉.
Извините что не на английском. 😅
Посмотрел ваше видео , очень интересно !
Я катаюсь на моторчике My1020 36v1000w . И акумулятор у меня ~26в100AH (лилий железо фосфатный)
Использую акумулятор от солнечной станции . Боялись что електричества не будет . После мемяца обстрелов из аритилерии , решились на столь дорогую пркупку.
Но хотелось бы поставить более мощьный мотор . И я смотрел в сторону модулей преобразователей.
Да, спасибо большое за Ваши експерименты !
Я вот хотел уточнить .
Сейчас я имею примерно 26V*27А=700w
Если добавыть модуль выйдет 36v*20a=720w. Результат не впечатляет . 😊
Сталобыть нужно выбирать двыгатель с более высоким напряжением !?
Например я возьму 72в*20а=1440w. !
(Но в реальности будет 1000ват , модуль не сможет дать больше 😂)
Буду очень рад услышать Ваше мнение, как мне добытся большей мощности ? Без замены акумулятора.
Wow!
Thanks for such great feedback!
I am glad to be of help.
Your thinking is on the right track.👍👍
The major issue with these converters is the current limit at the input of the converter.....which is usually around 30A....if you push it a bit, maybe 40A.
This means that at your batteries' nominal voltage of 26V, you would only be getting less than 26*30A watts from the converter - we have to account for conversion efficiencies. Yes, your math above is correct.
These converters are designed to deliver more power at high input voltages. Hence, to get the kind of power your need, you will need a more powerful boost converter capable of providing high output power at lower voltages.
This means that you need a converter that should be able to process greater than 80 to 100A at the input.
I hope this makes sense.
Overall, your design logic of higher voltage at lower current is really the gold standard for high efficiency for most electric vehicle systems.
Success wishes on your diy projects, my friend!👍

Hi sir can I use the converter to feed the motor directly as a controller. Thank you so much
Again, this is an interesting idea. I love that you are thinking outside the box!👏👏👏
However, honestly, I would not recommend you do it because, at lower voltages, you will damage the converter as a result of high current surges.
But if you are feeling adventurous, you can definitely try it. But you must know that there is a big risk of damaging the converter, or your motor, or both.
I hope this helps.

I need to drive a 72v 2000watts motorcycle. What should i use as a boost converter.
Please see my response to your previous question on the other video.
I would only recommend these converters for steady state or continuous power load of less than 1200W at a minimum input voltage of 48V.
You may have to conduct some product research if you need more power....but heads up, if you find anything, they will be very expensive.
I hope this helps.

So it seems to me that the DC/DC converter has a constat current feature referred to the INPUT current, not on the OUTPUT current.
So changing the input voltage, setted the maximum input current, will end up absorbing more input power and delivering more current at 48V on the output. Am I right?
My thought was that the constant current setting will be acting on the output current, but that's not the case right?
Your thoughts are on the right track. 👍
However, the converters have input/output current limit (usually about 30 to 40A).
The constant current function only applies to the output. It is a built-in function that helps the converter to regulate the current delivered to the load, to whatever level the user desires.....as long as the set CC point is less than the rated current limit. Also, you will have to have an input power source that can deliver that amount of current.
I hope this helps.

@@theinnovati0nlab782 I didn't thought that cheap thing could be so sofisticate and well engineered. Thanks.
@@grazianoturbogas
Yeah, that is the power of mass production. Honestly, for the price, the product is amazing!
i wonder if 2 separate boost converters connected to 2 separate say 36 volt lithium packs could be used in parralell where only the output is connected ,has this been tried yet ,i know both the inputs and outputs were done ,but separated?
This sounds like a great idea for a simple experiment. You should give it a try and see what the output response of your converter system would be like.
Keep us posted on your progress. Let me know if you have any questions.

@@theinnovati0nlab782 im actually doing parts list ATM to build your modified converter so i can use it in a 85 volt 10 to 20 amp ebike charger i am pretty sure that ill have to have an input voltage of 55-60volts to be able to 85 volt 20amp output though.as you know these converters work alittle strange
hello im just curious ,when you focused in on the oscilloscope ,the flat line was supposed to show what ? as far as an ebike goes ,introducing a dc to dc cc /cv boost converter will just add to much inefficiency ,if you run 72 volt motor on a 48volt battery youll get more distance than boosting a 48 volt to 72 volts
i roughly saw greater than 20% wastageand that was just in the conversion itself ,there is a trick to these boost cons,the less you have to boost the voltage ,the more efficent and less heat, the larger you have to boost the more current you need at the input and the more heat
have you had any of the units you got ,faulty? or are they good,some people have had alot of faulty units?
This measurement of the DC Generator output. The flat line shows that the dc generator is outputting dc voltage/power. It also shows that the added rectifier and filter caps are preventing pulsation at low rpms.
I explained it all in the video.
Did you watch the entire video?
we just couldnt see the readings ,and we werent sure if it was connected or not21@@theinnovati0nlab782
Blah blah not enough it should be done with a heavy load and measure it im sure battery booster will go down drain in few seconds

Why only 180w @ 12v? For 500w ebike output 42 amps @ 12v.
It is due to the current limit on the converters.
It was also explained in the video.
👍👍

next do it with an ESC and a BLDC
ESC?
So why did you not talk about how you did the speed control from your hand throttle to the motor. I feel that you are not giving full information here.
Thanks for the feedback.
I see your point. However, I had already covered that in a previous video. This video was meant to be a follow-on video that builds on the previous one that explains the concept of the Electric Motor Load simulator. But you are right, though oftentimes I forget that these videos exist as separate entities.

can i connect the dc generator to my bike pedal so that it can generate volts, and that volts, im going to connect it to my electric motor, will it work then?
It is not clear to me what you are hoping to build. However, the function of the DC Generator is simple - as long as you as you can find a way spin the amateur shaft, it will generate electricity. Just like our setup in this video. I discontinued the video series because the CZcams algorithm was not recommending the videos, so they were not doing as well.
Please watch the design concept video below.

thanks, i just want to run my electric bike using dc generator, without using battery
@felixescober6798
I understand.
However, it may not be the best idea. You are going to encounter a lot of energy losses due to inneficiencies. I would not recommend doing that. But if you are curious, you can build it as an experimental project - just to satisfy your curiosity. Trust me, I have done many projects of such nature myself...hahaha.
Summary:
You will always need a battery system for any electric drives system.

На DC моторе 48в 1000ват.там где выходят два провода черный и красный можно сделать реверс?????мотор не сгорит??
It's a permanent magnet dc electric motor..Reversing the wires will reverse the of the output if you are using is as a dc generator. As a motor, reversing the polarity would cause the motor to spin in the opposite direction.

Hoe kan ik een 48v 20ah batterij het best opladen tijdens het rijden zoals een auto het doet. Oneindig rijden. Zoals een dynamo van een auto. Ik heb een elektrische tricycle die rijd 85km/p.
Great question.
Electric cars use regenerative breaking sustem that produces electricity when breaking.
Gas powered cars use alternators that are drive by the vehicle engine to recharge their batteries.
So you may need to research the implementation of a regenerative breaking system.
I made a dc generator video a while ago. I discontinued the series because people didn't seem too eager for it at the time.
You can apply a similar concept to see if you can make something work. Regenerative breaking is all about replacing a vehicles break pads with a high power dc generator. Instead of wasted power as heat on the break pads, your dc generator converters the cars kinetic energy into electricity and saves it in your battery.

How many item do I need to make 120ah for inverter without spend $300-1500 for dumbass batteries
Wonderful question.
One very important thing to note is that boost converters do not replace batteries. They only raise the voltage component of your required power to match your application. You don't want to overload your battery by using multiple boost converters.
The ugly truth is that batteries are expensive, and if you need to source more power, then you may need to spend a little bit more to increase the capacity of your battery system.
I hope this helps.
Success wishes on your projects.

Great question.
👍👍👍
First of all, it seems that what you will need will a powerful buck converter - if you are looking to down, convert your 48V battery to 12V. Unless I misunderstood you.
Honestly, if you already have a powerful 48V battery, I wouldn't recommend doing the down conversion to 12V because you will be burning a great deal of power due to converter losses and low efficiencies. It will be better to just use a 48V motor. We only suggestion these boost converters to those who cannot afford expensive higher voltage battery systems.
I hope this helps.
