Very Nice work, I personally appreciate your work. it is very detailed and straight to the point.

Thank you for this video, I had been looking for this information since I have a broken one and the output MOSFET had been changed to a lower specification one.

Thank you for providing us such a good information... About this boost converter, since it doesn't have short circuit protection I think its easy to get burned.

Five batteries to one is a big difference in weight ratio. Great stuff!

your the best youtuber i ever seen. the best product review ever to reveal the truth.. i buy also this converter to get 60v and about 10ampere is enough for me for my project and i used computer power supply with 40 ampere as an input voltage because i thought that this converter can handle 60v output from a 12v input but the converter is died. i subscribe to your channel best regards from philippines.

Amazing work sir

In my personal experience most of the products we are buying are built with substandard components, they are made to the product work at a fraction of there capabilities, why you may ask just to make money I bought a buck converter for about 2$ I used it for a short while and it broke within a day, definitely I was using it at it's very max I decided to replace the main ic LM 2596s which costed me 2.50 $ more experience than the entire unit, but handled abuse very well and didn't heat up as quickly, usually it's one component that falls, you may want to consider that anyone reading this comment.

Totally agree with you. I have the same experience.

I got one of these to charge a 58 volt camp pack with a car alternator/ battery. I am worried I will hook it up and fry it. What should I do with each pot before hooking up? Then How do I sneak up on settings?

*You have some great information here and i really appreciate you sharing it . I have a question. How do we know what size boost converter do we need for our project. What determines if the converter is suitable. My input and output voltage falls within the range. What else is important to know if it works?*

I've had three of these. First one I was not able to adjust output current or voltage that was stuck was at 119V DC. I used it as a 48V ebike Regen module well above it's rated power for about a year until the Mosfets blew. The second one I used to boost a constant 12.5 volts input at 20amps (250w),to 55v output at 4amps for battery charging. I used it with a cooling fan. I used a recording amp and volt meter, and about 30mins the input current jumped to 48amps but the fuses did not blow, bur rather melted, and then the output diodes shorted. The third unit I set up the same but limited input current at 12V to 10 amps. Charged an 800wh 48V LFE battery pack at about 2 amps, a couple of times. Then, on the third attempt I powered the converter up, made no pot changes. checked output at a stable 55v, connected the battery and instantly the fuses and main power regulator blew.

Greeting! Very educational videos!!! Well done Professor! Which converter would you recommend to make a power supply with DC input and output~ 4-6V and ~8-12A adjustable ! That it can work without interruption and overheating for a long time!

I like all of your videos. You said you connected voltage sensing and then I saw something yellow. Where is that from?

Another Question my friend , I have 2 48v lithium battery banks my 3.2v batteries I saw preformed better at 3.5v but 3.5x15.= Dc 52.5v but the issues are my battery combiner is only 48v and will blow at 52.5v but also my inverter is an EASUN 5 KVA pure sine wave inverter charger 48v PWN

I put the 1800W version on an ebike and it failed after 5 minutes, halfway up the hill. Output voltage is now the same as input. :-( 16V to 55V to a 48V 18A peak ebike controller.

спасибо за такой обширный тест

hey thank u for all the information, iam running it with an ebike, battery 36v 7,5 a to 44-50v, it is a bit tricky to set the current, but it is getting better....finally the solution is a bigger battery, a second same size in parallel, to have more amps to boost,

Is there a way to boost its voltage to atleast 120v?

I had this fail converting 12v to 80v on 3 hbs86h boards driving 34SSM1460-EC1000 steppers. It lasted about 45 seconds.

Thought of buying this converter to power my class D home made car amplifier rated at 1000 watt rms. But with a car battery at 13 to 14 volts while the engine is on. It required at least 80 ampere input to power a 1000watt rms output. After seeing this video it's not possible to power up my amplifier. with 30 ampere max input. Since my car is a small hatchback with a 35ah battery and 90 ampere alternator my dreams just shattered like a mirror with this module. Have to use a normal dc to dc converter not a boost converter

Thanks for the testing. I've blown up a couple of these, their "1200 watt" rating is super inflated. I was trying to use them to power a 36v ebike with 12v battery, and it just didn't work..the ebike was like 500watt, it just blew up the input fuse like you showed until it just died. I was wondering how to fix them. If you buy from amazon you can return them, but I'd rather just fix them or even improve them as there was not another option that I could see.

The Chinese calcution in your case is 500w÷12v= 41 Ah. So thats double of what it can handle. My bike is 350w÷24v= 14Ah and yes it works. For me its the perfect way to use my 24v batterys on my 36v bike.

The weak side of these boosters is the big Mosfet, it is rated way too low voltage, I think max 85Volts and then you have output of like 80, take in mind inverse voltage is higher than this. so it does not break due to over current but to over voltage. I have one of these modules and it broke without load after just a few hours of use. So I fixed and improved mine by replacing the one big mosfet with a parallell pair of B31N20D instead and it have not broken again since that was done. another weak side is that the module cannot limit current below the input voltage, so it will basically try to lower the voltage down to VCC and if that is not enough to limit the current it can´t go lower than this meaning if you short the output below VCC there is no current limit at all and you also burn the module or fuses instead.

There also might be a problem with the smaller transistors not making proper contact with the heatsink or none at all thats why the transistor on the input was reaching 85C on the pins meaning the real temperature of it was probably at 100C iam going to buy one but il replace the silicone thermal pads with thermal paste and maybe add paper or cardboard above the smaller transistors for better contact with the heatsink for better thermal transfer

@@WattHour I am planning to use two boost converters in parallel, to move extra energy from solar-charged 12v battery to 48v battery. The setup will work every day, so I want to have CONSIDERABLE redundancy both in terms of power and reliability (I am from Ukraine and I think we might have some issues with electricity supply again next winter). That is why I have chosen such a margin in power redundancy and dual converter setup. As for relays - I plan to add a charge controller, that would connect the boost converters to 12v battery only between it's 90% and 100% state of charge, and 150w at 12v is 12.5A, and when having 300W that would be 25A, so I am planning using two boost converters + 2 relays in parallel, in order not to stress the relay with 25A of connected DC(!) current, but split in half for 2 relays. I agree about it all sounding like an overkill, but I would be glad to hear a better option. Thank you!

I have a CCTV NVR that uses a 52V adapter for power. The problem is, we face constant power outages, resulting in a loss of security coverage.

The efficiency numbers are incorrect. Overlays and calculations don't match measurements from the Load 9:29 : 616.6W Input - Load shows 600W (97% Efficiency) Yet Overlay shows 480W Output and 77.8% Efficiency 10:11 : 942.7W Input - Load shows 900W (95.4% Efficiency) Yet Overlay shows 720W Output and 76.4% Efficiency Some are wrong, others are OK.
