I'm jealous of that load tester i love it i want one. It can tell you how much balls your module has, sort of speaking but they are so expensive.They are invaluable for the workbench. When I'm browsing through ALI Express your never sure witch modules are worth the money but watching your videos makes it easier to choose.Great stuff man, keep testing those modules so to keep people from wasting their money.

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.

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.

@thetribal697 Жыл бұрын

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

@Pulverrostmannen 9 ай бұрын

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.

@w4st3lander 8 ай бұрын

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

@Pulverrostmannen 8 ай бұрын

@@w4st3lander yes the thermal connection is not especially high on it. When I modified mine I actually put the new mosfets on a separate heat sink that have a temperature controlled fan on it that I also built. But as long as the switching mosfets no longer is on the stock heat sink that part have not gotten hot anymore for my part. I use my device in a home made Lab power supply. I have 3 rails built in the same unit and can go 1-20V 9amps. And 20-83volts up to 20amps (this module) and 40-380V 200ma. I can use all 3 outputs at the same time too if I want with a combined power of about 500 watts

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.

If I have the best video about something in the world and someone else has a worst video in the same topic but has more subscriber, youTube will suggest and bring up that channels' video and viewer never find my videos. So more suggest translations to more view and it translates to more income. just checked overall subscribers ration to view of my channel and it is 5.5%. So only 5.5% of my viewers are my subscribers which is very low and when I create another video, the 94.5% of viewers will never know. I have spent over $15k equipment + 100s of hours of my time and for the month of October 2022 my income shows to be $98.23. So I am bugging and have to bug for subscription. This is my last try and I will give it 6 more months and will gave up if it does not bring an income that worth keep working. Only pranks and junk is appreciated on KZfaq.

I want to use this 1500W boost converter to convert 12V battery backup from the UPS to 52V because I have found that this is the solution. Now I have two questions: 1. Will it work? 2. How do I change the current? (Can you please make a video or guide me through) (NB: I am somewhat of a noob when it comes to electronics. What I know today is learned through such videos.)

@@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!

This is a very disjointed review and very hard to follow. I would appreciate a table of results and recommendations at the end.

@@WattHour I see you have chapters, however I like to start from the beginning and follow your testing through to the end. If you do that there are lots of breaks and it sounds disjointed. It needs to flow smoothly from one test to the next with a summary at the end like: Nice unit and has high efficiency provided you do not exceed 25 amps at the input. Exceeding 30 amps can cause catastrophic results. The comments were meant to be constructive. I enjoy your test videos and encourage you to do more.

@@peterdkay - Most of this guy's "reviews" are disjointed and very hard to follow. He doesn't accept feedback or suggestions from viewers. It could be solved with a summary at the end.
