Thank you so much for this review. I love how you give a brief overview of the componentry, then an extensive review of the working at many input and output voltages. The thermal views are fantastic and give great insight into the possible longevity (or not) of the circuit. It is great that you show off the weakness and strengths of the circuit too. Again, thanks for another great review!
Hey Robojax, I ordered this module. I will be using it to charge a 48V battery bank @59.2V between 3A-15A. My power supply is a 48V 1000W DC motor ran by a gas engine. What do you recommend I do in terms of upgrades? I watched your full video and appreciate it greatly, I will firstly add solder as you mentioned. Thank you.
I have used several of thesee with good results, after blowing several of them. I highly recomend ading a soft start on the power input to keep the input capacitors from blowing the unit when they are in a discharged state.
Volts + current can be adjusted separately for a resistance load, but only in the UP type adjustment. To lower adjustment, the unit is unpowered, and restarted with pots at lower setting. Then the upward adjustments are done again. The Capacitors have to be denergized for reuse. Also , current goes down as volts is increased, Example - no 6 amps at 28 volts! You need an adjustable Boost type 900w or 1200watt converter to get higher amps and volts same time. (even though it says 600w. That's only at the 13v lowest setting from 12vDC.The dealers don't tell you that! I use the E bay rugged dc converters preset for volts and amps desired at high wattage. Then just add inline fuse to switch and battery.
I decided to buy one because you went into the details to convice the product I wish if there was any model name for easy reference rather than desctriptive 10-24 V to 65-72 V boost converter 600W etc
when I buy the item, I ask them to pub the model number, but there are 1000s of sellers and producer is missing LOL perhaps 100s of producers there so they never put model. In fact they don't assign a model number.
A complete schematic would be helpful for me as I like to exploit the CC operation with external control. In which range is the the current settable with the on-board potentiometer? Could you elaborate please on the sophisticated generation of the 5V voltage?
wow. schematic may be found online. But your projects is interesting. this was just one time video making. Not worth looking at it as most Chinese product, this doesn't have model number so people can't find it if they need it.
This helps a lot! Thank you!!! I am planning to run my laptop directly through 12v 26Ah battery. But instead of using modified sine wave car inverter, to power my laptop 220V AC adapter giving output of DC 20V 6.75A... Planning to replace the adapter with direct 12V to 20V 6.75A DC boost converter... And with the testing you performed I believe it will easily be able to replace my 150W laptop AC adapter with the one you showed, and I will save on spending money for pure sinewave inverter. Hope it fits right... Do let me know if i still need to be worried about anything else? Can you guide what might be the max Amps at 20V output with 12V input this module would have handled easily?
You are welcome. It should handle the load. Make sure you have fuse installed and set the constant current to the current never goes above the limit. Good luck.
Nice review, thank you! I am working on a project and I have 4.9 volts and 2.7A as input. I need to get out this boost converter between 11.5 and 12.5 volts. The current has to drop below 0.3A. Also the load is between 250 and 350 watts. Is it capable to achieve these values? May I need one or two of these boosters? Best regards
Some of your higher power step up reviews are missing. Did the suppliers get upset that you called them out on not meeting specs? :) You blew one up about a year ago, and I sent you some replacement mosfets, did you get it working?
Hello Steven, Thank you and yes I received them. I didn’t know how to contact you yo thank you. It took them awhile to arrive and didn’t know what project they belonged so keep them somewhere in my lab. I will find them and see to if they belong yo this module and use them. Thanks again. I am very busy I hope I will make use of them.
31:47 - 33:43 Very interesting for a electrics scooters, 36v of batery but is not constant, however put on Booster in batery to ECU, Input: 33v-42v of batery to booster and output: constant 41-42v for Ecu power. Opinions ?
check first the current the mixer is drawing while running and connected to the battery. if the current is blow or equal to the values I've tested, it should work.
Hi! Can you help me? My I-Adj (CC) doesnt work. I have a Ecoflow Powerstation with 12V 8A Output an a Hoymiles Inverter. If Current over 8A the Ecoflow turn off. Now i have a 1200W DC/DC Converter. It works, but it is to big. Now i will use this Converter. But without CC does not work. What can i do?
of course you won't see it. you can't adjust it unless you have a load. this is just liming the load. your load is determining the current. so connect a load that for example needs 2A. then you can adjust it to limit it for example to 1.5V and you will see it works.
Excellent video! I have the same module and unfortunately i can't adjust the current. I always get the maximum of the input. Should i check the mosfet or the current mode PWM IC?
Hello, it seems you've skipped the video. I just spend time to watch and the video and I've explained it. so please watch it. I always answer questions that has not been answered in the video.
this is what this does. if you want to boost current, then voltage should be low so the output total power is about 15% less than the input. Yes. it should work this way.
I just watched the video yo make sure I have given example of increasing or decreasing current. I need it has been shown in the video when setting input voltage if 12V. Please watch .
When it comes to efficiency evaluation, how about accounting for the rather high heat developed!? Wouldn’t it easily show much larger total energy developed than js the input energy?! The module control firmware must very well be taming/constraining … ;(
Effeciency is about energy which is converted to heat. I am not sure if I showed the thermal image in this module but if the module is not going to heat above 85C then it should work fine. please see my channel on energy called WattHour youtube.com/@watthour
@@robojax Thank you very much for your response. Sure, the heat is - in principle, unjustifyngly - considered as loss, but in terms of the energy conservation the sum of developed heat energy and the electric power available at the output should not exceed the energy supplied by the battery at the input. But the legitimate question should be if that is the case, even in the conventional DC-DC converters implementations where its the very basic inductor-core's B-EMF might not be allowed to manifest fully!? Please let me know if you would be interested to possibly jointly explore/pursue the underlying aspects?!
Hello, this is exactly why I made the video for. Please watch. I have explained the input and output voltage and also I have tested it. So you watch fully and come to conclusion.
I mentioned all specs including min and max voltage. it doesn't matter where the voltage or current is coming from. Regardless of input voltage changes, the output will stay stable.

hai robojax i actually looking for buck converter for a projects (tethered drone) the idea is sending Ac/DC 200-300v (adjustable) through a 100meter tethered cable to the drone (buck converter) we tested we need 24v/800w to keep the drone operational. so basiclly we looking all around the internet we can't find DC step down 200v to 24v .. in my hand we already have the AC/DC 0-300v 1.5a adjustable power supply. and a buckconverter brought from ebay (70v to 24v 800W ) we do try sending 70v from ground and stepdown to drone buck converter( 24v 30amp) it seems like the buck converter never reach 30amp) so my guess i need to supply greater voltages to the buck converter.. do you have any recommandations any DC/DC step i shall buy for my applications ? any reply in this would be highly appricated Thanks Regards Fei
Hello, thank you for writing. I am very busy with my Udemy.com course and my TH-cam and family stuff. In short you need 800W 24V. this would be very heavy. from the word drone I understand that it must be involved in heavy flying machine. 33A 24V is unusual. So you may get two modules in parallel with 15A each. I would suggest sending 36V over wire to the drone (I know the wire will be heavy to carry that current). Can't think of anything.
@@robojax The drone it self is 4kg and have the capacity to MTOW 10kg . anything below 6kg shall shall be okay (i have 800w 24v attach on the drone unit MY bad there is some typo at the beginning) i might as well try get two 15A modules in parallel . as for the cable we using low weight cable like this (www.gore.com/products/tethered-drone-cables) Very Much appriciated for your value input.. Thanks again. :D
This is exactly the reason I made video for. To answer such questions. You can answer even by reading the title of this converter. But test proves if what they claim is true.
First it is physics law that the power NEVER increase. It will decrease but not increase. For example 20W input (10Vx2A=20W) and ouput can be aproximately 18W due to losses. (18Vx1A=18W). You can only change voltage and current. There is about 10% to 15% losses
first you need to draw the schematic and get all the components, then study them to see how the design work. finally if you know how it functions, removing the feedback means unstable system. unless you add external different way to stabilize it. I am not sure if it worth working on this. I'd go with new designs. But you may try.
Hi, 1-first set the voltage to the maximum voltage of your battery. 2-Disconnect the power 3-short circuit the output (connect + and - together) 5-Connect Ampere meter (ammeter) in series with the load (see this video for measuring current th-cam.com/video/9jwCc7uPGoc/w-d-xo.html ) 6-turn ON the power 7- and then turn the CC potentiometer to set the current and read it on meter. 8-disconnect the short from output Done. Good luck.
you are inputting 50V and 2A so P=50(2)=100W what are you expecting at the output? you can't get more than 100W because of physics law. so you will get 100 -100(1.15)=100-15%= 85W the 15% are losses in the module.
I can input 20v at 30a. There is plenty of power going in. I had to go up to 22.5v in to get it to output more power. Maybe you should know the setup before you critique
Offfff ! For real ? . Can you just test and equivalent with low cost ? And if you can see if you can get any from old powersupply or some mosfet in printer laser boards . You may like what you can get from old stuff
You see I don't like to throw away any electronic equipment just for need a transistors . You can get many transistors ( it may not work like original ) with very low cost like 10 PC's for 20$ including shipping ( best quality = 70 % from original )
not sure, if this is a question you should start with "Can I find input 150v output 400v for hi vote inverter?" and if that your question just use Bing/Google and search "input 150v output 400v boost converter" and I am sure you will find something.
Good work sir please send me a perche a kit for power supply for hho kit i required hho kit power supply board.my project to enuf what a price it a kit ? I am interested this device wont to perch
@@robojax Woul doy like to review one of theese? www.aliexpress.com/item/32822711981.html?spm=a2g0s.9042311.0.0.2b054c4dzsSun6 There are versions marketed as 1500W, they have fan shipped with them, others, like 1200W ones seems to still have fan port, but don't ship with a fan...
Your question caused me to watch the video because I explain everything that I think is important. And for sure I have said where you can get it. Please watch the video without skipping from the beginning to the end and you will get the answer.
what do you mean how can you do this? The input maximum is 60V and you just set the output voltage shown in the video. so you set it to 24V. Just search for 600W DC 10-60V on AliExpress.com or Amazon or eBay.com
Can I use this charge a 18s(3 x 6s) Lipo batteries granted I only charge to a maximum of 68.4v or 3.8v per cell not 75v Also more importantly use Turnigy DLUX Auto Checker(s) on each XH port not as primitive checker but indeed for the 50ma "Auto Balance" it claims to provided once imbalance is detected during charge/rest/discharge/storage ultimately dedicated balancing with auto sleep DLUX claims. Maybe connect 6 Deluxe Auto checkers to each 6s battery for a total of 18 Turnigy DLUX Auto Checker(s) using a 6X XH adapter on each 6S. Possible? LVD(Low Voltage Disconnect)
You will short circuit the output (this has short circuit protection) and measure the current. Adjust the current to your desired value. Then remove the short curuit from output. Set the voltage to your maximum voltage and connect it to your device. When the battery is charged, the output voltage increases to the maximum and charge will stop. Warning: Lipo batteries are very dangerous, change them only on solid non-falamable sureface away from valuables or human.
You are suggesting that I make appropriate adjustments to both the voltage and current before connecting it to the 18s battery. Would you suggest fusing both the input and output of this boost converter, or output only for further short circuit protection. Lastly would you suggest using Shockey diodes as reverse voltage protection & does this boost converter have reverse flow built in? Electronics-Salon has long offered 12v-48v DIN rail mountable LVD modules with dip switch settable disconnect reconnect ranges. I understand LVD are applicable with all battery chemistry's power supplies Etc.
yes. before commenting it you have to have proper value set. Put the fuse at input if you want. If you watch the video, do not have much hope . This can't supply even 400W.
i did so many ripple test and people did not care. too much hassle to to measure and record. So I gave up. people don't care about details. they just get the module and use. So I am learning from them not to offer good quality videos.

I’m glad I saw this video ! Before purchasing this module .
Is there a better module with the same characteristics that you can recommend?
I have used several of thesee with good results, after blowing several of them. I highly recomend ading a soft start on the power input to keep the input capacitors from blowing the unit when they are in a discharged state.
Great tip!
How do you add a soft start? So how do you keep the input capacitors from blowing up?
Volts + current can be adjusted separately for a resistance load, but only in the UP type adjustment. To lower adjustment, the unit is unpowered, and restarted with pots at lower setting.

Can one modify the boost circuit to reach a fixed boost factor without the IC trying to stabilize it to a fixed voltage output?
first you need to draw the schematic and get all the components, then study them to see how the design work. finally if you know how it functions, removing the feedback means unstable system. unless you add external different way to stabilize it. I am not sure if it worth working on this. I'd go with new designs. But you may try.
@@robojax thanks
you are welcoem.
Hi can you teach me how to set this boost converter CC current, input is 16.8v from a 4s4p lithium battery pack and output is 19v 7a. Please help
Hi, 1-first set the voltage to the maximum voltage of your battery. 2-Disconnect the power 3-short circuit the output (connect + and - together) 5-Connect Ampere meter (ammeter) in series with the load (see this video for measuring current th-cam.com/video/9jwCc7uPGoc/w-d-xo.html ) 6-turn ON the power 7- and then turn the CC potentiometer to set the current and read it on meter. 8-disconnect the short from output Done. Good luck.
@@robojax thank you kindly
Can I supply 40V and output 13.8V? To charger the battery 12VDC.
No. This will always higher voltage than input. It is boost converter. Check buck converter or step dow converters. I have so many videos
@@robojaxMost step dow with low capacity - Many thanks
Couldn't get more than 49.5v and 2.05 amps out of it. About that it would pull double the input current with no change.
you are inputting 50V and 2A so P=50(2)=100W what are you expecting at the output? you can't get more than 100W because of physics law. so you will get 100 -100(1.15)=100-15%= 85W the 15% are losses in the module.
I can input 20v at 30a. There is plenty of power going in. I had to go up to 22.5v in to get it to output more power. Maybe you should know the setup before you critique
Why you buy another one if there a possibility to fix the unit by only change the mosfet
because the mosfet + shipping= New module
Offfff ! For real ? . Can you just test and equivalent with low cost ? And if you can see if you can get any from old powersupply or some mosfet in printer laser boards . You may like what you can get from old stuff
You see I don't like to throw away any electronic equipment just for need a transistors . You can get many transistors ( it may not work like original ) with very low cost like 10 PC's for 20$ including shipping ( best quality = 70 % from original )
I have 100s of item and 100s of projects to do. The mosfet and shipping was almost the price of new one.
input 150v output 400v for hi vote inverter
not sure, if this is a question you should start with "Can I find input 150v output 400v for hi vote inverter?" and if that your question just use Bing/Google and search "input 150v output 400v boost converter" and I am sure you will find something.
Good work sir please send me a perche a kit for power supply for hho kit i required hho kit power supply board.my project to enuf what a price it a kit ? I am interested this device wont to perch
on eBay search or search for "600W DC10-60V" and you will find it.
wow, saved me $11
Good to hear that.
@@robojax Woul doy like to review one of theese? www.aliexpress.com/item/32822711981.html?spm=a2g0s.9042311.0.0.2b054c4dzsSun6 There are versions marketed as 1500W, they have fan shipped with them, others, like 1200W ones seems to still have fan port, but don't ship with a fan...
anyone jput them in parallel?
48 v 600 watt possible from 12 v?
I would have to watch the video to answer it. please watch and get the answer. I don't remember anything about the module .
Where can I buy that??
Your question caused me to watch the video because I explain everything that I think is important. And for sure I have said where you can get it. Please watch the video without skipping from the beginning to the end and you will get the answer.
in put 60v out put 24 v how can i do this or can some one tell me where to buy a converter
what do you mean how can you do this? The input maximum is 60V and you just set the output voltage shown in the video. so you set it to 24V. Just search for 600W DC 10-60V on AliExpress.com or Amazon or eBay.com
Can I use this charge a 18s(3 x 6s) Lipo batteries granted I only charge to a maximum of 68.4v or 3.8v per cell not 75v Also more importantly use Turnigy DLUX Auto Checker(s) on each XH port not as primitive checker but indeed for the 50ma "Auto Balance" it claims to provided once imbalance is detected during charge/rest/discharge/storage ultimately dedicated balancing with auto sleep DLUX claims. Maybe connect 6 Deluxe Auto checkers to each 6s battery for a total of 18 Turnigy DLUX Auto Checker(s) using a 6X XH adapter on each 6S. Possible? LVD(Low Voltage Disconnect)
You will short circuit the output (this has short circuit protection) and measure the current. Adjust the current to your desired value. Then remove the short curuit from output. Set the voltage to your maximum voltage and connect it to your device. When the battery is charged, the output voltage increases to the maximum and charge will stop.
Warning: Lipo batteries are very dangerous, change them only on solid non-falamable sureface away from valuables or human.
Yes sir
You are suggesting that I make appropriate adjustments to both the voltage and current before connecting it to the 18s battery. Would you suggest fusing both the input and output of this boost converter, or output only for further short circuit protection. Lastly would you suggest using Shockey diodes as reverse voltage protection & does this boost converter have reverse flow built in? Electronics-Salon has long offered 12v-48v DIN rail mountable LVD modules with dip switch settable disconnect reconnect ranges. I understand LVD are applicable with all battery chemistry's power supplies Etc.
yes. before commenting it you have to have proper value set.
Put the fuse at input if you want. If you watch the video, do not have much hope . This can't supply even 400W.
Perfect. This is truly the most interesting TH-cam channel by far. Thank you
What about Ripple?!
i did so many ripple test and people did not care. too much hassle to to measure and record. So I gave up. people don't care about details. they just get the module and use. So I am learning from them not to offer good quality videos.
@@robojax Please offer quality videos
