Hello guys! We hope that you like this video. Honestly, we got tired of chasing our tails trying to make 15-minute videos that is expected to capture a college semester whorth of information and detail....so we decided to make this video longer. However, the idea was to present in chapters such that you won't have to watch it all at once. We are experimenting on this new long form format. Please give us your feedback and comments to let us know what you liked and what we can improve on. We greatly appreciate you guys and we thank you for all your support. 👍❤️ The Innovati0n Lab
How about building a boost converter? I had the idea of using a transformer and push pull inverter circuit. Would it's efficiency be that bad? It would only need a feedback for registration, and rectifier and cap to smooth things over. And using a decent transformer from a microwave or welder it could do 1000-1500watts no problem. The issue would be input voltage it would be comparably narrow. With in 12v+/-, of course it will weigh a ton.. I got into electronics because I wanted to build a large inverter, and a 72v20kw motor controller for a ev conversion. These converters are ok if the voltage is only 6v or so or less about 2-4 is better, definitely less than 24v if performance is wanted. I wanted to build a brushed series wound motor controller. To use in a small converted car. Using a couple forklift motors. The 36v rating is 3.3k. So at 72-96v it should be a more useful power, requiring additional cooling. I have heard of these ran at 144v plus . however a 20s to 24s lithium battery should do fine. Especially with two motors, have a awesome day!
Oh my goodness!! I literally love your feedback!!! 👍👍👍👍 Honestly, I love it when people think outside the box or outside the trending norm. I think we both share some beginning history when it comes to power. I have the same exact story....hahaha. I spent a long time when I was younger, building inverters and rewinding huge transformers. LOL. I will give this a serious thought, run the efficiency numbers. But regardless, it will make a for a very fun and exciting project. Stay tuned, my friend! 👍😎❤️ - The Innovati0n Lab.
Thanks for the wonderful feedback, my friend! 👍👍👍 We started this channel to use our knowledge to help other electronic hobbyists and enthusiasts like us. Your feedbacl is greatly appreciated and highly inspirational. Thanks again! 👍😎 The Innovati0n Lab
Thanks, great video. This looks perfect for my needs. I need to charge a small 96 volt from a large 48 volt battery. Can you recommend how to create a control circuit to prevent overcharging the battery?
Thanks for the great feedback.👍👍👍 It really depends on the type of battery you are looking to charge. What type of battery chemistry is it? - lead Acid, li-ion, or lithium phosphate?
Will this make a 12v lifepo battery charger a 24v lifepo chatger ? Does it convert 13.6 v into 27.2 v ? Would the smaller cheaper one work just as well dont need the digital read out TIA
Yes, it should be able to do most of those things if you adjust the settings correctly. However, I am not the manufacturer of the converter, and I can't vouch for its performance. You should try to test it yourself to know if it will work for your application.
I love buck converters! Could you review the ZK-SJ20 and ZK-SJ30 ? I bought both of those, currently testing for a parallel , scallable 2000A (30V) power network behind solar system.
Wonderful! I would love to. Please share a link to the products - better if it's on Amazon or Ebay. It seems you are working on such a cool project. 👍👍👍 Success wishes to you. The Innovati0n Lab 💥 www.theinnovati0nlab.com
I am glad that you are thinking innovatively.👍👍 However, from the performance of the converter, when I first tested it - as you saw in this video, it doesn't work very well if the difference in voltage between the output and the input voltage is greater than 5V. I plan to test this converter to see if it would work better as a cheap solar battery charger. But you can order one online and give it a try. Please share your findings with us. 👍👍 The Innovati0n Lab💥
Please watch the entire video - if you can. I believe I covered all the specs in this video. I really don't memorize the specs of all these converters - especially if the video was made a while ago. You could also find the converter online and verify the specs that way. 👍👍
I was thinking of using one of these to power my laptop from my lifepo4 battery bank. This would be efficient than using a 2000w AC inverter and big 200w power adapter.... but I'm not sure on the quality of the device, fail-safes like over voltage, output current ripple etc, is it worth using this for a $1500 laptop? I can't find a proper 200w laptop charger anywhere for 12v bank... any thoughts?
@@theinnovati0nlab782 Probably not the smartest idea, but I went ahead and just did it... Converter wired to barrel jack, connected to a "dc to HP laptop barrel adapter" which (supposedly) has the correct resistor inside to provide the "smart" comms to the laptop... Once it's going it charges well and converter doesn't get warm enough to kick in fans, only strange thing is that charging will only initialise when laptop is on lock screen, sleep, hibernate or off - probably something to do with the HP adapter... but once it starts charging then it keeps going and has lowered my power consumption by literally 100w! Worth it? time will tell, if it fries my laptop I will update here lol
@aciidphreeek Wow!! 100W power savings is quite significant. Now you got me thinking about this as a future experiment. The only sad thing is that the high voltage DC Power concept would only work for non inductive loads like TV, laptops, computers...etc. It will not work or be efficient for inductive loads that require AC power. Thanks again for sharing. The Innovati0n Lab💥
Do you have any boost converter that keep output voltage constant till input reach output voltage, then turn duty cycle to 0% and output same voltage as the input voltage. That can supply 10-15 amps
Wonderful question. What you have described is essentially how every converter with output voltage feedback stabilization works. All the converters I have reviews on this channel do this function. I hope this helps. The Innovati0n Lab 💥 www.theinnovati0nlab.com
Great job. During the output load test on resistors I could see the CC led on, not the CV one. Seems that it was somehow in current constant mode. What was the maximum current setting for these tests? Because there is no reason it performs well on batteries and not on resitors...
Thanks a lot for the amazing feedback!👍👍👍 I greatly appreciate it. This video was from many projects ago, and I am trying to recollect - I had to go watch the video again..hahaha. I believe that during the resistive load testing, I had the output current set to the maximum point. What I observed with these converter was that it doesn't do well at large input-to-outout voltage differentials. It performed well with the battery charging because there was only a 6V differential between the input (24V) and output (30V). If you shoot for the Max output voltage of 120V with a low input voltage, then the converter losses output voltage regulation. I saw that the manufacturers passively mentioned this on the datasheet but very conveniently left it out on the product description on Amazon. I hope this helps. 👍😎 The Innovati0n Lab💥
It's the same exact music for the first 5 minutes and repeated later on. Download the epidemic sounds app or go to their website and search for the track. 💥Original track title: PARTY BANGERS With an Epidemic Sounds subscription, you can download the entire stem package of the song and edit it as you want.....so what you heard was the different variations that I made out of the original track during the video editing. Some instances I amplified some instruments, some instances I removed stem drums,...some instances I removed bass...and so on. 😊 Too much detail goes into making these videos!😊 Thanks for the appreciation. Let me know if you have further questions. I am always happy to help - as long as you are sharing and promoting our channel😋😂 👍👍 The Innovati0n Lab 💥 www.theinnovati0nlab.com
someone told me this... is it true... "The only problem with those is when you shut the power off and then it back on it reverts back to 12 volts. You have to open your box and press the button to turn the booster on manually" I'm in a boombox building group.. i was going to use it boost my 12v 25ah lifepo4 to 25v.. That way i could get the max watts out of my amplifier.
Honestly, I am not surprised that this converter would behave this way because of the digital controls it has. However, this is not something that I tested, so I can't really confirm that for now. For your project, I would recommend looking into the 1500W converter that I have used in lots of my videos. They do not have the power reset behavior that you were concerned about. th-cam.com/video/2KyBwwldqkk/w-d-xo.htmlsi=Jun2QbwiCStGPdLJ Please share our videos and recommend our channel to your project group if you find this helpful..

Thanks for the GREAT review...it was very valuable to me. I would like to comment on two rather secondary (general) issues: 1) The LED digital display can be rather hard to read as is, however, the solution is simple: Simply cover the display with a piece of RED electrical tape...MAKES ALL THE DIFFERENCE IN READABILITY!!! 2) Concerning the power resistor array. As shown, if near 500W, or even half that (250W) is used, this arrangement will quickly BURN UP in high duty cycle use! I have many years of experience here! The resistors should be placed with AT LEAST one inch between them, and on a heatsink about THREE or FOUR times as large PLUS a powerful fan blowing through the fins with heatsink grease under the resistors. ...looking forward to your additional, very valuable, videos!!!
Hi Dale, Thanks a lot for the wonderful and constructive feedback as usual! Always greatly appreciated!👍👍👍 I will try the red electrical tape for the next video! Wonderful idea.....I never thought of that.😊 As for the load resistors, you are equally correct. However, as you saw in the video, the intention was for a very short duration test. Also, there was actually a stand-alone as a fan that was placed off the test bench that was cooling the test load. I had to suppress almost all the sound because it wasn't really pleasant... Hahaha. Thanks again for such wonderful feedback. 👍😎 The Innovati0n Lab.
Awesome presentation! I can't wait to see how you take advantage of this soft start for solar charge control. I'm using the MPT7210A that I got for about $35, but it goes up to 72V max. However that't perfect for me as charging my 48V LiFePo4 requires up to 58.4V only. It's an MPPT Boost charge controller with very nice color LCD and it stores multiple charging schemes, which is very nice. It also capture the total Ah going to the battery.
Wonderful! Thanks a lot for sharing your experience with the MPT7210A. Personally, I use the EPEVER MPPT controllers, and they work great as well. I will be testing the soft start solar on this converter to know if it will be good for solar charging soon. Stay tuned, my friend! 👍😎 - The Innovati0n Lab 💥
Absolutely, I will definitely add it to my list of videos to be made in the near future! Stay tuned, my friend! Thanks for the feedback. 👍😎 The Innovati0n Lab.
Great thinking! 👍👍👍 However, it depends on how low of an rpm we are talking about. You may have to add a massive rectifier and filter circuit to clean that up. But if the rpm is too low, that could present a high risk to your load. 👍😎 The Innovati0n Lab.
Thanks for the wonderful feedback. We appreciate all your support. We will do more projects in the future in those lanes. Stay tuned, my friend! Also, we need help from our audience in growing our channel. You can play a big part by sharing our videos with friends and other people of similar diy like minds. 👍😎 The Innovati0n Lab.
I like the resistors in the aluminum housing and the heat sink you put them in. I need to get a few of them for a dummy load to keep battery from overcharging
Thanks for the great feedback. 👍👍👍 I like the resitors as well. You can get those on Amazon...a pack of five, 100-Watt resistors for only $12. I will update the description with the link. Thanks again, my friend! 👍😎 The Innovati0n Lab
Please watch the video and check my summary section. I believe I explained the limitations of this converter at high voltage outputs. It only works well if the input voltage to output voltage differential is very small. In a nutshell I won't trust this converter to handle that much load. 👍😎 The Innovati0n Lab 💥
Can u test it chargingg a bank of super caps .. at 18v from a 12v inputs ..and then put your adjustable current load resistors on the caps also parralell.. and see how the amazon con performs ..🙄🤔
Maxwell cap bank from china alix press ..50$$$+_- 500F x6..16v max rated..83F bank... iv done some tests with solar input and 12v dc motors loads ....2222see if i can get the maximum watts out of my 80w POLY CRYSTEL panels.. Direct driving motor ..mini 70watt water pumps .. with out will sux up 17v and the full 3...to..4 amps the panels can make .. They love it .. Mono crystel panels dont.... no good .. When i get time i load up a vid ..👌
Hahaha! Never, I love those converters. I saw this one, and I liked that they added the digital control option in the design. This was just another converter review video. Thanks for the feedback! 👍😎 The Innovati0n Lab
Great idea. I have some supercaps, but I am not sure I have enough for an 18V bank. I will see if I can fold that into my solar charger test that I am planning on conducting - with the new converter. I have a feeling that it will perform well.....just a feeling. We shall see. Stay tuned. 👍😎 The Innovati0n Lab.
Great question. The specs from the manufacturer is a bit deceptive. The answer is that I don't know. I honestly haven't seen the schematic, I just reviewed the converter. I am currently working on a converter design and will be able to sell it through our website below. 👍😎 The Innovati0n Lab💥 www.theinnovati0nlab.com
Voltage is energy, when loads consumes the energy of the source (your battery) , the source gets depleted. If you drop a stone on the floor, the potential energy of the stone goes from some value to 0. If you short circuit a battery the potential energy of the battery goes from some value to 0 and the voltage will be 0 if you measure it during the short circuit event. See the analogy here? Now the "why" question should be addressed to the creator of our Universe, why did he create electromagnetic field specifically as it behaving right now?
I have 2 solar panels..rated 400 watts- 30.6 VMP - 12.9 IMP each and I have them wired in series to create 800 watts ...and connected to my bluetti EB150 solar generator, which can accept a maximum of 60 volts @ 10 amps/ 600 watts of solar charging the built in li-ion batterys. I am only able to get a maximum of 532 watts of input solar charging, which leads me to believe that I am only getting 53 volts @ 10 amps at the input of my solar charging jack on my Bluetti. Since my panels are rated max output of 12.9 amps/ IMP, im assuming I have about 2.9 amps leftover not being used by the MPPT charger built into my bluetti. Would the dc to dc converter in this video, be able to convert/bump up my dc voltage to 60 volts @ 10 amps, coming off my 2 solar panels, so I could input the full 600 watts charging capabilities of my bluetti EB150 ? I do not like it that I am losing around 70 watts per hour of charging capability with my current setup and since my 2 solar panels are wried in series for a total of 800 watts max, I am confident I should be getting more than 530 watts out of them and into the bluetti EB150. THANK YOU FOR YOUR GREAT VIDEOS. .
You are absolutely right to have such a concern. However, your solar generator could have a current limit that prevents it from getting all the power that your panels can deliver. Also, keep in mind that every converter system MPPT or not, will present some power loss and efficiency issues. Also, keep in mind that your solar panel will only deliver the max power at 12 noon when the sun is directly over the panels. Hence, another way to improve your solar panel yield would be to consider investing in some single axis solar trackers. I hope this helps. The Innovati0n Lab 💥 www.theinnovati0nlab.com
@@theinnovati0nlab782 evidently, my blietti eb150, can accept up to 68 volts at 10 amps max....so theoritically, I should be able to pump 680 watts into the EB150...before any risk of damage . Im only able to get 530 watts into as of now, using 800 watts of olsar panels. Do you think this dc to dc converter will allow me to do better ?
Wonderful! Thanks for the great feedback. 👍👍👍 I hear you. I am the same way sometimes. Noted! It's just that during the actual testing, it gets really noisy, and some people tend to complain about the noise. However, I greatly appreciate your feedback. We need feedback like this to help improve our content. Thanks again. 👍😎 The Innovati0n Lab 💥
you made a big mistake.. load of 20ohm.. never going anywhere.. 2.maybe 3 ohm .. i use this 900w to charge my 48 li/ion 14s.. and my 16s lifepo4.. 42v dc in output 15 amps.. also 60v lifpo4 still 15 amps.. from 42v in.. do the math. v=i.r and so on.. the 9oow is one of the best i have fond. quick and visible. easy to see what you are doing.. but 20 ohm load will never pull any AMPS.. FULL STOP.. MAINS MAY BE ..OR DID YOU FORGET ..
Your math is simply wrong. I thought I explained the math behind the 20 Ohms in the video. At a converter output voltage of 120V, a 20 ohm resistive load at the output should translate to a 720W load. You need to use the power equations: Power Dissipation across a resistive load is given by the formulas below; P = (V^2)/R .....OR P = (I^2)/R Where; V = to the known voltage across the resistor. I = the current through the resistor. R = the resistance value of the load resistor. Now, let's apply one of these formulas; If we used a 3-ohm resistor as you had suggested, the power dissipated by the load..we can call it PD(load) = (120^2)/3 = 4800W If we use the 2-Ohm resistor, PD(load) = (120^2)/2 = 7200W The converter is rated at 900W.....enough said, yes? All the same, thanks for the comment/interaction. However, next time, please take the time to watch the entire video and let me know if there is something you did not understand. Please be patient with the videos....I know that some of them can get long..hahaha. But don't rush into uninformed conclusions - not with my videos. I am not like your regular free energy TH-camrs. A lot of research and calculations are done in the background with all my videos.👍👍👍 At the end of the video, I gave a comprehensive summary, and I mentioned that the converter works better with battery charging (also shown in the video) and not for resistive loads. The converter performs better when the input-to-output voltage differential is not too large. In your case, you are using a 48V power supply to charge a 60V battery - only a 12V differential, so this is the reason you are getting a good charging response. Try doing the same thing from a 12V or 24V power source.....tell me about it afterward. Anyway, I am glad the converter is working for you. -The Innovati0n Lab💥 www.theinnovati0nlab.com
I loved the bass line in the intro, didn't even know my subs could do that lol. Nice job on the booster. I never got to test my paralleling board for the one you tried to parallel but was wondering about this one to. board but it's in the mail. I made a PCB that includes the trims for the CC and CV and cut off so I can see if paralleling everything helps, boards in the mail still.
I made a solar powered scooter 2 years ago, I get good range with a 48v battery plus a little extra range from the panels however to keep the weight down the panels are about 60W less than the min you want to charge a 48v bank so it takes to long, add the 60W more and your to heavy. I'm trying to now use a 36v battery bank cause that charges 70% faster with my panel setup and homemade MPT circuit but now I need a booster to boost 36v to 48v for the scooter and the red one (15001800W booster) so far is the best I can find but it's in my opinion not going to last long if I can't parallel it. I also have the idea that I could make my own more efficient one buy removing the ability to adjust it, just a analog boost from 38v 48v so a 1.75 transformer I guess.
Wonderful! Thanks for the great feedback.👍👍 I am glad you liked the bass line. That is actually my favorite part of the video editing....hahaha. Well, keep us posted if you were able to make some good progress with your paralleling effort so we can learn from you as well. 👍😎 The Innovati0n Lab
Awesome! It seem that you already have a great plan. I do agree that the 1500/1800W converters are really awesome - especially for the price. However, as you already know the power limit seems to be tough challenge to get through without having to design your own board. I am currently working on a higher power design that was inspired by the video below; 👇👇👇 th-cam.com/video/oPhLpekQ4q4/w-d-xo.htmlsi=wEcgLKmuwIApMDwl Thanks again, my friend. 👍😎 The Innovati0n Lab
MANUFACTURER SPECS: INPUT CURRENT: 0 TO 15A OUTPUT CURRENT: 0 TO 15A Please go read the specs on Amazon before commenting. That is a 55 minute review that captured lots of detail and you are simply just going to bring out your red pen to find non-existence faults? Thanks for the appreciation and inspiring feedback.
You miss understood the specs, Imagine Input 60V, 15A which would obviously give 900w Now if output is 90V how could current be 15A coz that would be 1350w which is deinetly not rated to that brother... Because atinput of 60v and output of 70v to 120v you can't draw current of 15A coz you will definitely exceed the converter limit leading to burnout of fuse or other components. So being "55 min review" it doesn't mean that you can't make a mistake man...
@michaelbenard6758 There is a level of mutual exclusivity built into these hyped up specs by Amazon vendors! What they are claiming is that under the most optimimal conditions, you can either up to 900W of output power....OR... under a different condition, (lower output voltage), the converter can provide up to 15A of output current. The output current rating was actually verified in this video - if you actually took the time to watch the video! Also, go to the SUMMARY section and listen to my commentary. The mistake you are making in your calculation is that you are trying to extrapolate their 900W output power rating by doing an I×V multiplication using the "MAXIMUM" output ratings of the voltage and current specs. This is not always the case. Most converter manufacturers will provide these maximum ratings because it makes the converters look more appealing. As a matter of fact, the rated maximum output voltage of this converter is 120V. So if we were to go by your output IV extrapolation, then we will be looking at 15 * 120 = 1800W? They are saying that the converter is capable of providing 0 to 15 Amps of output current. With 15A Amps being the maximum. What they will NEVER tell you is that you should expect the converter to deliver 15A at 120V....... ......and this is where your calculation is coming from. This is the trick they play and personally I find this misleading as well. I was not wrong in basically reading the specs as it was listed. Again, I provided the product link in the description. Go read the spec for yourself. RATED INPUT CURRENT: 0 TO 15A RATED OUTPUT CURRENT: 0 TO 15A The word "RATED" as used above basically means that this essentially a manufacturer claim and not an absolute. I agree that the provided output ratings are misleading as they do not add up under certain conditions, but I did not build the converter. Your comment implies that I made a mistake when I basically was reading what the Amazon vendor stated as the converter specs. Maybe you can talk to them about making the correction on their listed specs. Finally, my "55-minute video" comment was not meant to say that the duration of the video should somehow make it above mistake/flaws. I was pointing out the fact there was an absolute lack of appreciation from you regarding the resources, time, and effort that went into making this video. We welcome constructive and optimistic feedback that goes like this..... 1. This is what did you right.... 2. This is where I think you can improve on.... 3. Suggestions.... This is all I am saying. Thanks for the interaction. -The Innovati0n Lab💥

Thanks, great video. This looks perfect for my needs. I need to charge a small 96 volt from a large 48 volt battery. Can you recommend how to create a control circuit to prevent overcharging the battery?
Thanks for the great feedback.👍👍👍
It really depends on the type of battery you are looking to charge.
What type of battery chemistry is it?
- lead Acid, li-ion, or lithium phosphate?
Will this make a 12v lifepo battery charger a 24v lifepo chatger ? Does it convert 13.6 v into 27.2 v ? Would the smaller cheaper one work just as well dont need the digital read out TIA
Yes, it should be able to do most of those things if you adjust the settings correctly.
However, I am not the manufacturer of the converter, and I can't vouch for its performance. You should try to test it yourself to know if it will work for your application.
I love buck converters! Could you review the ZK-SJ20 and ZK-SJ30 ? I bought both of those, currently testing for a parallel , scallable 2000A (30V) power network behind solar system.
Wonderful!
I would love to. Please share a link to the products - better if it's on Amazon or Ebay.

do we have any buck converters 100vdc-12v-48vdc vdc in this price point? i had to spend hundreds to make my golf cart work :-/
Good question.
I really don't know.
You may have to search online.
Is this applicable for solar panel voltage booster from 35-50v variable voltage to a constant 120v?
I am glad that you are thinking innovatively.👍👍 However, from the performance of the converter, when I first tested it - as you saw in this video, it doesn't work very well if the difference in voltage between the output and the input voltage is greater than 5V.
I plan to test this converter to see if it would work better as a cheap solar battery charger.
But you can order one online and give it a try.
Please share your findings with us.

Can you give 60v as input????
Please watch the entire video - if you can. I believe I covered all the specs in this video. I really don't memorize the specs of all these converters - especially if the video was made a while ago. You could also find the converter online and verify the specs that way.

I was thinking of using one of these to power my laptop from my lifepo4 battery bank. This would be efficient than using a 2000w AC inverter and big 200w power adapter.... but I'm not sure on the quality of the device, fail-safes like over voltage, output current ripple etc, is it worth using this for a $1500 laptop? I can't find a proper 200w laptop charger anywhere for 12v bank... any thoughts?
Wonderful, I like your innovative way of thinking.
However, I wouldn't recommend doing that.

@@theinnovati0nlab782 Probably not the smartest idea, but I went ahead and just did it... Converter wired to barrel jack, connected to a "dc to HP laptop barrel adapter" which (supposedly) has the correct resistor inside to provide the "smart" comms to the laptop... Once it's going it charges well and converter doesn't get warm enough to kick in fans, only strange thing is that charging will only initialise when laptop is on lock screen, sleep, hibernate or off - probably something to do with the HP adapter... but once it starts charging then it keeps going and has lowered my power consumption by literally 100w! Worth it? time will tell, if it fries my laptop I will update here lol
@aciidphreeek
Wow!!
100W power savings is quite significant.
Now you got me thinking about this as a future experiment.
The only sad thing is that the high voltage DC Power concept would only work for non inductive loads like TV, laptops, computers...etc.
It will not work or be efficient for inductive loads that require AC power.
Thanks again for sharing.

Do you have any boost converter that keep output voltage constant till input reach output voltage, then turn duty cycle to 0% and output same voltage as the input voltage.
That can supply 10-15 amps
Wonderful question.
What you have described is essentially how every converter with output voltage feedback stabilization works. All the converters I have reviews on this channel do this function.
I hope this helps.

Great job. During the output load test on resistors I could see the CC led on, not the CV one. Seems that it was somehow in current constant mode. What was the maximum current setting for these tests?
Because there is no reason it performs well on batteries and not on resitors...
Thanks a lot for the amazing feedback!👍👍👍
I greatly appreciate it.
This video was from many projects ago, and I am trying to recollect - I had to go watch the video again..hahaha.
I believe that during the resistive load testing, I had the output current set to the maximum point. What I observed with these converter was that it doesn't do well at large input-to-outout voltage differentials.
It performed well with the battery charging because there was only a 6V differential between the input (24V) and output (30V).
If you shoot for the Max output voltage of 120V with a low input voltage, then the converter losses output voltage regulation.
I saw that the manufacturers passively mentioned this on the datasheet but very conveniently left it out on the product description on Amazon.
I hope this helps.

Can i use 12v motor using this booster?
Please can you elaborate?
I didn't understand your question.
someone told me this... is it true... "The only problem with those is when you shut the power off and then it back on it reverts back to 12 volts. You have to open your box and press the button to turn the booster on manually" I'm in a boombox building group.. i was going to use it boost my 12v 25ah lifepo4 to 25v.. That way i could get the max watts out of my amplifier.
Honestly, I am not surprised that this converter would behave this way because of the digital controls it has.
However, this is not something that I tested, so I can't really confirm that for now.
For your project, I would recommend looking into the 1500W converter that I have used in lots of my videos. They do not have the power reset behavior that you were concerned about.

Thanks for the GREAT review...it was very valuable to me.
I would like to comment on two rather secondary (general) issues:
1) The LED digital display can be rather hard to read as is, however, the solution is simple: Simply cover the display with a piece of RED electrical tape...MAKES ALL THE DIFFERENCE IN READABILITY!!!
2) Concerning the power resistor array. As shown, if near 500W, or even half that (250W) is used, this arrangement will quickly BURN UP in high duty cycle use! I have many years of experience here! The resistors should be placed with AT LEAST one inch between them, and on a heatsink about THREE or FOUR times as large PLUS a powerful fan blowing through the fins with heatsink grease under the resistors.
...looking forward to your additional, very valuable, videos!!!
Hi Dale,
Thanks a lot for the wonderful and constructive feedback as usual! Always greatly appreciated!👍👍👍
I will try the red electrical tape for the next video! Wonderful idea.....I never thought of that.😊
As for the load resistors, you are equally correct. However, as you saw in the video, the intention was for a very short duration test. Also, there was actually a stand-alone as a fan that was placed off the test bench that was cooling the test load. I had to suppress almost all the sound because it wasn't really pleasant... Hahaha.

Awesome presentation! I can't wait to see how you take advantage of this soft start for solar charge control. I'm using the MPT7210A that I got for about $35, but it goes up to 72V max. However that't perfect for me as charging my 48V LiFePo4 requires up to 58.4V only. It's an MPPT Boost charge controller with very nice color LCD and it stores multiple charging schemes, which is very nice. It also capture the total Ah going to the battery.
Wonderful!
Thanks a lot for sharing your experience with the MPT7210A. Personally, I use the EPEVER MPPT controllers, and they work great as well.
I will be testing the soft start solar on this converter to know if it will be good for solar charging soon.
Stay tuned, my friend!

Worded if one 12v low rpm magnet generator can be replaced for the 12v battery ?
Great thinking!
👍👍👍
However, it depends on how low of an rpm we are talking about. You may have to add a massive rectifier and filter circuit to clean that up. But if the rpm is too low, that could present a high risk to your load.

The inductor core is too small for 120v load
Can it run 90v DC motor water pump as I have 2 solar panels of 580w each
Please watch the video and check my summary section. I believe I explained the limitations of this converter at high voltage outputs. It only works well if the input voltage to output voltage differential is very small.
In a nutshell I won't trust this converter to handle that much load.

Why putting load on it makes input voltage drop ?
Great question.
The specs from the manufacturer is a bit deceptive. The answer is that I don't know.
I honestly haven't seen the schematic, I just reviewed the converter.
I am currently working on a converter design and will be able to sell it through our website below.

Voltage is energy, when loads consumes the energy of the source (your battery) , the source gets depleted. If you drop a stone on the floor, the potential energy of the stone goes from some value to 0. If you short circuit a battery the potential energy of the battery goes from some value to 0 and the voltage will be 0 if you measure it during the short circuit event. See the analogy here? Now the "why" question should be addressed to the creator of our Universe, why did he create electromagnetic field specifically as it behaving right now?
I have 2 solar panels..rated 400 watts- 30.6 VMP - 12.9 IMP each and I have them wired in series to create 800 watts ...and connected to my bluetti EB150 solar generator, which can accept a maximum of 60 volts @ 10 amps/ 600 watts of solar charging the built in li-ion batterys. I am only able to get a maximum of 532 watts of input solar charging, which leads me to believe that I am only getting 53 volts @ 10 amps at the input of my solar charging jack on my Bluetti. Since my panels are rated max output of 12.9 amps/ IMP, im assuming I have about 2.9 amps leftover not being used by the MPPT charger built into my bluetti. Would the dc to dc converter in this video, be able to convert/bump up my dc voltage to 60 volts @ 10 amps, coming off my 2 solar panels, so I could input the full 600 watts charging capabilities of my bluetti EB150 ? I do not like it that I am losing around 70 watts per hour of charging capability with my current setup and since my 2 solar panels are wried in series for a total of 800 watts max, I am confident I should be getting more than 530 watts out of them and into the bluetti EB150. THANK YOU FOR YOUR GREAT VIDEOS. .
You are absolutely right to have such a concern. However, your solar generator could have a current limit that prevents it from getting all the power that your panels can deliver. Also, keep in mind that every converter system MPPT or not, will present some power loss and efficiency issues.
Also, keep in mind that your solar panel will only deliver the max power at 12 noon when the sun is directly over the panels.
Hence, another way to improve your solar panel yield would be to consider investing in some single axis solar trackers.
I hope this helps.

@@theinnovati0nlab782 evidently, my blietti eb150, can accept up to 68 volts at 10 amps max....so theoritically, I should be able to pump 680 watts into the EB150...before any risk of damage . Im only able to get 530 watts into as of now, using 800 watts of olsar panels. Do you think this dc to dc converter will allow me to do better ?
I would love it if you could call out your readings and numbers, easier than trying to read the screen enjoy listening more than watching

Baby good for a dual 12-volt 100 amp setup charging but the voltage regulator shut off
Thanks for the feedback, but I didn't understand your comment.
you made a big mistake.. load of 20ohm.. never going anywhere.. 2.maybe 3 ohm .. i use this 900w to charge my 48 li/ion 14s.. and my 16s lifepo4.. 42v dc in output 15 amps.. also 60v lifpo4 still 15 amps.. from 42v in.. do the math. v=i.r and so on.. the 9oow is one of the best i have fond. quick and visible. easy to see what you are doing.. but 20 ohm load will never pull any AMPS.. FULL STOP.. MAINS MAY BE ..OR DID YOU FORGET
..
Your math is simply wrong.
I thought I explained the math behind the 20 Ohms in the video.
At a converter output voltage of 120V, a 20 ohm resistive load at the output should translate to a 720W load.
You need to use the power equations:
Power Dissipation across a resistive load is given by the formulas below;
P = (V^2)/R .....OR
P = (I^2)/R
Where;
V = to the known voltage across the resistor.
I = the current through the resistor.
R = the resistance value of the load resistor.
Now, let's apply one of these formulas;
If we used a 3-ohm resistor as you had suggested, the power dissipated by the load..we can call it PD(load) = (120^2)/3 = 4800W
If we use the 2-Ohm resistor, PD(load) = (120^2)/2 = 7200W
The converter is rated at 900W.....enough said, yes?
All the same, thanks for the comment/interaction.
However, next time, please take the time to watch the entire video and let me know if there is something you did not understand. Please be patient with the videos....I know that some of them can get long..hahaha. But don't rush into uninformed conclusions - not with my videos. I am not like your regular free energy TH-camrs. A lot of research and calculations are done in the background with all my videos.👍👍👍
At the end of the video, I gave a comprehensive summary, and I mentioned that the converter works better with battery charging (also shown in the video) and not for resistive loads.
The converter performs better when the input-to-output voltage differential is not too large. In your case, you are using a 48V power supply to charge a 60V battery - only a 12V differential, so this is the reason you are getting a good charging response.
Try doing the same thing from a 12V or 24V power source.....tell me about it afterward.
Anyway, I am glad the converter is working for you.

I loved the bass line in the intro, didn't even know my subs could do that lol. Nice job on the booster. I never got to test my paralleling board for the one you tried to parallel but was wondering about this one to. board but it's in the mail. I made a PCB that includes the trims for the CC and CV and cut off so I can see if paralleling everything helps, boards in the mail still.
I made a solar powered scooter 2 years ago, I get good range with a 48v battery plus a little extra range from the panels however to keep the weight down the panels are about 60W less than the min you want to charge a 48v bank so it takes to long, add the 60W more and your to heavy. I'm trying to now use a 36v battery bank cause that charges 70% faster with my panel setup and homemade MPT circuit but now I need a booster to boost 36v to 48v for the scooter and the red one (15001800W booster) so far is the best I can find but it's in my opinion not going to last long if I can't parallel it. I also have the idea that I could make my own more efficient one buy removing the ability to adjust it, just a analog boost from 38v 48v so a 1.75 transformer I guess.
Wonderful!
Thanks for the great feedback.👍👍
I am glad you liked the bass line. That is actually my favorite part of the video editing....hahaha.

It seem that you already have a great plan. I do agree that the 1500/1800W converters are really awesome - especially for the price. However, as you already know the power limit seems to be tough challenge to get through without having to design your own board.

@15:11 WT...
That 15A is the input current not output current men.!!
MANUFACTURER SPECS:
INPUT CURRENT: 0 TO 15A
OUTPUT CURRENT: 0 TO 15A
Please go read the specs on Amazon before commenting.
That is a 55 minute review that captured lots of detail and you are simply just going to bring out your red pen to find non-existence faults?
Thanks for the appreciation and inspiring feedback.
You miss understood the specs,
Imagine
Input 60V, 15A which would obviously give 900w
Now if output is 90V how could current be 15A coz that would be 1350w which is deinetly not rated to that brother...
Because atinput of 60v and output of 70v to 120v you can't draw current of 15A coz you will definitely exceed the converter limit leading to burnout of fuse or other components.
So being "55 min review" it doesn't mean that you can't make a mistake man...
@michaelbenard6758
There is a level of mutual exclusivity built into these hyped up specs by Amazon vendors! What they are claiming is that under the most optimimal conditions, you can either up to 900W of output power....OR... under a different condition, (lower output voltage), the converter can provide up to 15A of output current. The output current rating was actually verified in this video - if you actually took the time to watch the video! Also, go to the SUMMARY section and listen to my commentary.
The mistake you are making in your calculation is that you are trying to extrapolate their 900W output power rating by doing an I×V multiplication using the "MAXIMUM" output ratings of the voltage and current specs. This is not always the case. Most converter manufacturers will provide these maximum ratings because it makes the converters look more appealing. As a matter of fact, the rated maximum output voltage of this converter is 120V. So if we were to go by your output IV extrapolation, then we will be looking at 15 * 120 = 1800W?
They are saying that the converter is capable of providing 0 to 15 Amps of output current. With 15A Amps being the maximum. What they will NEVER tell you is that you should expect the converter to deliver 15A at 120V.......
......and this is where your calculation is coming from. This is the trick they play and personally I find this misleading as well.
I was not wrong in basically reading the specs as it was listed.
Again, I provided the product link in the description. Go read the spec for yourself.
RATED INPUT CURRENT: 0 TO 15A
RATED OUTPUT CURRENT: 0 TO 15A
The word "RATED" as used above basically means that this essentially a manufacturer claim and not an absolute.
I agree that the provided output ratings are misleading as they do not add up under certain conditions, but I did not build the converter. Your comment implies that I made a mistake when I basically was reading what the Amazon vendor stated as the converter specs.
Maybe you can talk to them about making the correction on their listed specs.
Finally, my "55-minute video" comment was not meant to say that the duration of the video should somehow make it above mistake/flaws. I was pointing out the fact there was an absolute lack of appreciation from you regarding the resources, time, and effort that went into making this video.
We welcome constructive and optimistic feedback that goes like this.....
