Very informative, the way it has to be. Super!
Glad you think so!
You probably dont give a damn but does anybody know a way to get back into an Instagram account..?
I stupidly forgot the account password. I appreciate any tricks you can offer me
@Axl Parker Instablaster ;)
@Arturo Reign i really appreciate your reply. I got to the site on google and im waiting for the hacking stuff now.
I see it takes quite some time so I will get back to you later when my account password hopefully is recovered.
@Arturo Reign It worked and I now got access to my account again. Im so happy!
Thank you so much, you saved my account !
Very helpful to me. Thanks man

Thank you for all that good info! Very detailed review! One question though: You have testet v2 model, what are the differces between v2 and the older model?
you are welcome. I don't know I mentioned it because if someone has V1 or older, if they see difference, they should notice.
@@WattHour OK, thanks anyway!

I have the V3 but seems the same in everything? Is there a way to set is just as constant voltage for the out?
When you set the voltage, that is constant voltage.Make sure to set the current to maximum.
What thermal imaging camera do you use? I would like to know the brand
The link to the camera is in the description under the video.

Hi I have a problem with this module, for some reason any of the buttons works, just work the + to increase voltaje, and got stuck in max voltage ( 32v) and I need to decrease that voltage but the ( - ) buttons dont change nothing, the same with power button, and mode. Just work the ( + ) any idea of what should cause this problem of the buttons dont working and just working the + button?
Hi, dis connect it from power, and connect a load to the output so capacitors are drained and no power left. This might help by changing any temporary settings. This module as I explained has microController. you can't program or do anything. if you try the above and it did not fix, may be it is damaged.
Hello, If you live in Canada or USA, I am giving away this DL24P 180W load and energy meter. Make sure to sign up for it ruclips.net/video/-UblSfUEY-0/видео.html
The weak part is the Schottky Diode beside the XL4015. When the converter is at full current and a high conversion rate (low on time if the xl4015 and therefore high duty time of the diode) it is overloaded and fails. When it fails it destroys the XL4015 too. I replaced it to MBR2545 on one of my converters. I will try a heatsink glued to the diode on the other ones. The XL4015 has a thermal shutdown protection. The diode has not. It is conducting the inductor current while the XL4015's off time.
The MBR2545 blew up too @ 36V Input and 8.4V output and full current. As the Amps of the MBR2545 (with both Diodes in the TO220 case) are far overrated this cannot be the cause. So it's more likely the 45V where exceeded due to some strange resonance at the inductor. I will post again if the SS56 blows up. Maybe I'll find time to investigate with the oscilloscope. Maybe it makes sense to change capacitors (too).
@@thomasmore260 how did it go man?
Pm me can you to install do solar panel of charger...
nince info sir...theres only one think i dont understand the CC-constant current its is normal when i charge a battery the lights turns on....
Pm me can you to install do solar panel of charger...
Input voltage varies between about 18-22 for my solar panels. Output is supposed to be 14.2 for the battery. Once the battery is connected, though, the input voltage value drops to the battery's voltage. That makes no sense to me, plus that is not what happens in this video. Can anyone explain why this happens, please?
Hi, it seems your battery is drawing more current than your solar panel can supply and as a result the voltage drops. For example if a solar panel under certain light condition can supply 15V 2A and you try to get 3A, it will drop the voltage. So limit the current the minimum of 500mmA for example to the battery and then connect this device to the soler panel and try different current values like 0.6A, 0.8A and increase to see and find maximum value. rememer when we talk solar, it is valid only under that particular time of day and lighting condition.
What is the minimum current you can set ?
Can you go as low as .005 ma?
Thank you
When I set the current you should see how the number is changed. I don’t remember it. It is shown in video or in the specs section of the video

Hello sir how are you plzz tell me about the protection of this device if out put prob tuch between
They is called short circuit protection and if this
Doyle has it I should have shown it. So watch the video .

Pm me can you to install do solar panel of charger...
Can I use 45volts in the input ?
No. You can see the voltage in the title and I have also explained it.
@@WattHour Is it have input over-voltage protection?
can this charger more than 1 batteries in parallel
Pm me can you to install do solar panel of charger...
Can this circuit charge car batteries?
Yes it can but car battery has something like 100Ah capacity and with this module if you charge it at 5A, then 100/5=20 hours will take to charge it.
You have to know to set the charge village for the battery like 12.8V or 13.2V , check specs so you can charge it fully
@@WattHour I understand. Thank you so much 😍
this thing did not work with solar panel. tried several of these in all kind of weather, failed everytime. Always shows current 0 no matter what I do. If you want to use laptop 20V charger then this thing is awesome.
Is this a buck boost converter?
I have done so many tests in the video. Please watch and see it.
20:19
At 33:06 efficiency 99% is not correct and at 34:17 and 34:43 also not correct! Negligence...!!!
correct it should be 81.6%. But the display is showing correct value. Thanks
