Nice tour of your system.

So electrifying :)

I did this ones but the power supply didn't have a max current limiter so it just turned it of and on every second or so but if you go through the charge controller you can probably set the current

How can remove the small ac currents that come along with the DC from the power supply. I realised that when i put the phase tester i saw some ac currents. If not removed won't they dammage the charge regulator

Good stuff!

Please be careful with that contraption. Your hand came very close to the exposed mains connections when you were tilting it to show us the voltage meter. I would make something to cover the connections.

So it's been 3 years since you made the video, how is the charge controller holing up?? I've always wanted to try this but my concern was that the charge controller wouldn't like the DC ripple from the power supply. They are, after all, made to use DC voltage from solar panels which is super clean. Thank you.

How's it going guys im a boilermaker by trade im kinda interested in all Handy work im learning about electricity now so please brake it down for me can i charge a 12v battery will this led power supply

My psu restarts as I connect load

hello sir, i got a question for u, i just fried 3 happymodel 6 in 1 1s chargers using 360w 24v input 15amps power supply, i checked all the wiring on power supply they are good, i wanna know why these multi 6in1 1s chargers fried please, i did use my cordless vacuum's power adapter which has 25v input and 0.8amp rating to power one of these happy model 6in1 1s chargers and it worked fine?? what i did wrong please please. thankyou.

I have a 0-9v charger that the higher the voltage the more amps can I use that only for the bulk stage of charging? Sayset to 6v and monitor battery when it hits 3.8 stop

You need to buy the version with current control. It's about $15 more or so. When you attach a power supply that has no current limiting it is just the resistance of your cabling and the battery itself controlling the current flow. If you have a low IR battery and normal wiring (12AWG to 16AWG) you are going to blow up your power supply. The battery will say "FEED ME ALL YOU GOT BABY" and these Chinese power supplies are never good for their rating. NEVER. I have the version that is 0-48V 0-10A and I never go above 8A because the fan is in full whining like crazy and it gets hot. The only way you can make this power supply safe is to put a power resistor in series with the load so that you increase the resistance enough to be in an acceptable range. You have to do the math on that. Or you could use very thin wires but we all know the problem with that. Another option would be to use a VERY long cable like several feet might be enough to add enough resistance to prevent the power supply from sending out more than 20A. All these methods at the end of the day just aren't worth it. You get no real control of how much charge current you are putting into your batteries so you can't charge small batteries and the lower the SOC the higher the current....the problem with that is a battery discharged to its lower areas of SOC like under 10% should be SLOWLY charged until the voltage has gone up some. So if you happen to discharge a 3.6V lithium ion down to 2.5V. it is recommended to charge at 0.1C max preferably 0.05C and you'd be out of luck with this power supply unless your battery is over 100Ah Here's a 1000W version. You can get them for $100 on aliexpress in any voltage you want. Voltage x amperage will equal 1000W so whatever votlage you choose dictates your current. www.ebay.com/itm/145068791427?chn=ps&mkevt=1&mkcid=28&var=444268320370&srsltid=AR57-fAymAoY0m-JoApw6H8TKKaZX4bGxBp5gkmDaPHpXtWqCeVSkUSnjZM Here's a cheaper 1000W I'd say this is a good price www.ebay.com/itm/404211140829?hash=item5e1cdc88dd:g:o~MAAOSw769g7LWY&amdata=enc%3AAQAIAAAA8JNTGJkHp7pYQ6%2F7qvB6ZP7vapWpek8vlOKs9DSdqxLDKXm29eKpXdmylDRgOxudmD355Ipuv%2B7xQ912rjfJXMqkilC7Yz4QDx6IdDVj0IE0Al9sOBwvBs7kT%2B9vL8AYT6XtXlA7L7bgO3qtkpb%2BhhhYPoVz%2FKq%2BX0Rcot6Gblgpgj8ekwYp7ZbsKUZ4q44wPjm9Fi7japffXMdN5nUk1EDamuQmMsDekhyEX0fMg020ARuFLQz35obAaRLTSx5McqgZwIAjLZ9cY310Lft6czm9keIvSH%2BLIN2sTtbn8RKnvddz28BDHJtjFOzi4crfow%3D%3D%7Ctkp%3ABFBMttLQkpVi Here's the 480W version on the Drok site SUPER CHEAP.

Can I use this to charge a car battery?

What is the current rating of the charge controller? Should the power supply rated current be greater than the mppt amp rating

Can you not just connect it straight to the battery?
