Anything will work, but to be technically correct, you need to choose the size of the wire according to the amount of current you want to take to charge your battery. If you're only using this to charge drill batteries like I did in the video, a size 1 or 1.5 mm will do, but if you're trying to charge a for example car battery you might want to consider 2 or 2.5 mm wires. the material does affect the voltage at the load, but not in this case as the distance is not too long,. Yes if it was for a load at 100 meter away from the charger, then you'd have to consider a few other factors such as material of the cable.

Below the video there are the descriptions. tet.trulymajestic.com

Yes sir! It certainly does.

Did it work for you

Thanks for watching and your nice comments amongst others that come from people who are just out there to attack for no reason. they seem to know everything, but they still watch a video like this that apparently bores them to sleep!!! It's nice to know there are still appreciative people out there.

Yes, Of course. Look in the description, where you can find all you need.

No Sorry! Not my expertise!

I'm not sure what you mean by using different plugs!

This is already explained in this video and the revised version of it, which comes as an end screen at the end of this video.

The black is negative and the black and white is positive. If you have a multimeter you can double check it with that too; if you connect the red probe of your volt meter to the "black and white" of your power adaptor, and the black probe of the meter to the black, the reading should be a positive value. I'd also included the link to buy a jack to PCB terminals, which you could buy and that way you wouldn't have to cut the cable at all.

@@totalelectricaltraining Great, thanks very much for your help.

If you mean to use it to charge a car battery! then I'd say there's no need to modify if the battery charger you have can supply enough current, however, even if it doesn't you can still use it, but it will take a lot longer time to charge!

Glad it was helpful!

That's only to charge a 24 volt battery, what I'm showing here in the video is for any range of voltage from 9 to 24 adjustable. So I'd say No.

You're welcomed!

@@ericweimar2245 PM me on my FB page with your questions! No problem!

@@ericweimar2245 Go ahead. Ask away!

You're welcomed!

To be honest, I've never worked with those yet. I have plans to get a big project underway, which will include those, but currently I cannot say that for sure. I don't want to say something that I personally haven't worked with. Thanks!

In the previous comments, I got the answer, Yes we can charge, Pb and NiCd batteries with the same. LiIon charging kit.

Yes, I've covered all these questions and more in my newer version video, which you should see at the end of this same video coming up at the end screen or here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pYVJHOdKzyo.html

Up to 3 Amps!

Thank you for watching and your interest Mr Kevin Gasrgandi, That's very difficult to tell, it all depends on how flat your battery is and also your power supply current. I cannot give you any specifics. Sorry!

No, I said the stop voltage should be set at a bit (maybe about 1.5% -1.6% of the rating of the battery) higher value. So, for example if your battery rating is 18 volts, then you set the top end at about 21-22 volts . Your minimum set value should be as high as possible without causing the relay LED to go off. I hope this is clear!

All the links are there under the video, tet.trulymajestic.com Thank you for watching and liking my video!

You're quite welcome! Just share and spread the word! Thanks

yes.

If the battery is almost dead, then you need to adjust the up and down voltage to where the relay clicks and the LED comes on and stays on, after it's charged a few hours, then you will need to change the voltages back up, and keep doing this until you get the battery to charge up to where it needs to be at. If the battery is completely damaged you might not be able to do any of these. you need to see what reading you get when it clicks On, and what reading you get when it clicks Off.

Yes, I don't see why not!

Thanks!

You need to specify a bit more in detail as to what you mean by which adaptor to use! I don't understand the question.

The board clearly shows where the input voltage is and where the output terminals are. Negative of both input and output are connected to the middle terminals, and the input positive is the terminal towards the edge of the board, and the other terminal is output positive.

All you need to do is to cut the adaptor's output plug, and strip the insulation off, then you have two wires, check with your multi-meter to make sure you connect the positive wire to the positive of the board, and negative to the negative terminal on the board.. or use this link to buy the connector for it; for USA; amzn.to/37jY1PS And for UK: amzn.to/36fLpKf

Let me just say that this is for Lithium batteries as well as Ni Cad ones. You cannot just connect the power to the battery directly and charge it that way, Having said that you actually could do that in theory, and even in practice if you could control the length of time the battery is under charge. However, you are talking about quite a few things here; You cannot use this for batteries with slots of a few contacts more than just the main positive and negative contacts. those have to be charged differently, which I will show you in my next video. Watch for that one. Third contact however is not a control of current at all in batteries like the ones I have shown in my video. If you open those packs, you will find the third plate (Contact) is not connected to anything, or it's just a ground. for the circuit, which again doesn't do much in this case. This regulator does more than just connecting and disconnecting the power supply to the battery, it controls the current and the charging, which is why it's called a regulator. All those ICs and components are not there for decoration. You can charge any power tool battery similar to the ones shown in this video, car batteries, Solar Panel batteries and many more with this regulator. I don't know what the strike out line is and I hope this has been helpful.

The link should be in the description, watch the revised video too, which is at the end screen of this video. Here's the link to the kit: tet.trulymajestic.com/battery-charger-kit-1/

Thanks for watching and your interest. You can find all the relevant links in the description at the bottom of the video.

you can make 24 v that way connecting batteries in series, but that doesn't make double the AH as you have presumed. To increase the Ah without increasing the voltage, you need to have the same number of batteries now connected in parallel, so in your case you will have a few in series and a few in parallel, it will be combination of series and parallel if you like! I hope that's clear!

welcome!

Did you buy the board from me?

Yes its ok i have manage to charge it thank you if the battery is lower than 10 V does that mean light goes out. it did come on but went out .

@@mauricevalladares9839 Yes, if the battery is too low, it won't come on. There's a trick that you can get it sorted, which I have explained in my second video, which you can find here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OL6DAVLk0ZU.html

Yes i thoughtthe regulator didnt stay onas battery was extremely low

Thanks for letting me know. It's corrected now here's the link again: totalelectricaltraining.co.uk/battery-charger-kit-1/

I think you need to watch this video, which explains all those things: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pYVJHOdKzyo.html

no, sorry! Because your maximum supply is 12 volts. The battery doesn't store charge, it only gets charged to the maximum you can supply.

What do you mean by Slotted batteries!

@@totalelectricaltraining, not the pedestal type but the 'blocks'.

@@TxRiverElf OK, I think we're getting our wires crossed here! Are you talking about slotted type battery chargers or batteries! Because I don't know what type batteries you're talking about. Can you send me a picture or a name or something so I know what we're talking about.

@@totalelectricaltraining like power tool batteries with slots_clamps that the charger PINS-tabs slot into.

@@totalelectricaltraining... never mind. Thank anyway.

PIANOSTYLE100 Thanks for your comments, and I'm glad it's been helpful to you as it's been to so many. Yes the links are there for anyone interested to get their teeth on a new practical little project. Appreciate your support, I really need it currently..

How did you get interested in doing this? I am an amateur woodworker and largely self taught.

@@PIANOSTYLE100 Electrical / Electronic Engineering has been my profession for decades. I started when I was only 11 years of age by making crystal radios, which by the way you can't find the earphones anymore (Not the same quality anyway), transmitters, Amplifiers and repairing radios and TVs and studied in this field and got my degree in it. and now I've been teaching it for years.

@@totalelectricaltraining I was going for EE. But my math background.was a bit week as.I got the higher calculus levels.

go to my website at totalelectricaltraining.co.uk and you can see everything under the right tab. thanks

Use the UK branch, you should find it there! Yes the U.S has removed it.

Yes, if they are chargeable!

@@totalelectricaltraining thank you for the speedy response. I buy broken laptops, tablets. Some are not repairable. But the batteries work just fine. I wanted to put them all together and seal it to make an emergency power pack. Can this be done with batteries of different mah and volt types?

Yes, and no! You'd better not mix and match technically as it will reduce their life span, but it will work for as long as they work! I have other videos teaching how to charge those kind of batteries, which should come at the end screen of this very video!

@@totalelectricaltraining thank you. I've been watching your other videos. I enjoy your wealth of knowledge.

@@JohnSmith-bh8um Thanks for watching, and your compliments. I hope you share my videos around to help others too! Thanks again!

OK. Let me save your time, your comment is just another one of those typical ones that are too worried about charging a battery; Listen Ihave explained this in my videos, not particularly in this video, but the revised version of this video, which you should see it come up at the end of this one, where I address these typical concerns. This charger is for any battery lithium or carbon monoxide or TNT type, AS LONG AS they have TWO wires or points of contacts to be charged as shown in this video and the other video, and your original charger doesn't do any miracle charging a two point battery, but doing exactly what this charger does. The middle point you're talking about in this case is not even connected to anything as shown in the video, it's just a gimmick. As explained again in my revised video for "concerned people" like yourself, If you have a battery with more than three ACTUAL points of contacts (Not just a decorative third point), then you need to pick the other battery charger board that I show in my video and I have in my website. SO I suggest you watch the other video and listen carefully before jumping your gun! Thanks! Take care and be safe!.

Thanks for your interest, but I can't tell what's gone wrong without seeing it.

Make sure you got the polarities right!

May be battery totally discharge so first charge little and then confirm positive and negative then try.

It could be that your battery is completely dead or the setting of the start value needs to be adjusted, probably brought way down, so it can switch on.

PM me on my Facebook, which you can find from my RU-vid channel.

Works for that too. I've tried. Don't see why it shouldn't!

@@totalelectricaltraining but you have no temperature sensing circuit to stop the charge when the batteries get too hot,

@@chazM6116 No need for that, when the batteries voltage reaches certain value the relay will switch off the power to the batteries. However it's not difficult to use an NCT to sense the temperature too.

You don't need time, when it's charged, it will switch the charging off automatically.

Thanks

@Bradley Ellis Thanks for your interest. Please look at the description of the video or go to Totalelectricaltraining.co.uk Thanks

I'm sure you can find, but I don't know where from! Sorry! Go to my UK link in the description and search!

PM me on FB !

Should be able to see it below the video.

The description is not marked.as.such...Look right below the phones video. in portrait view. Press the little arrow. It will be fairly small. I had 700 music lessons.etc. Then one day..I found it. Pianostyle100.

No you cannot, because it has to read the current voltage of the battery and charge accordingly, if they are all connected in parallel, then it won't know how long to charge it correctly.

@@totalelectricaltraining I've burnt a few batteries figuring it out the hard way 😂 I'll pull the good cells out eventually and use them for something else, it's slow going but I'm learning 🤷

No unfortunately each drill has a different battery pack size and shape, so it would be impossible to make a universal battery pack, but only a charger that can very to suit each pack. Thanks for your interest though.

What's up?

Thanks for letting me know. I've just updated the link. Hopefully it works now.

Where is the link I can't find it please reply directly

You made a video and teach us then!

Another troll alert!

I had the same sort of feeling. Setting the end voltage for a car battery (lead acid) would be ok as it reduces the charge when it gets there. Not so with Nicad or Nmhi. They go down in volts as they get to the fully charged point and start to heat up. Both types do this at slightly different points. Normally full charge is detected by the temperature going up or the voltage going down to turn off the charging

@@billhall1983 can you please give me advice as to what to do with the ni-cad battery"s cause i won't to get this kit for 12v ni-cad drill batteries but as i read your comment now i'm not sure, i like the kit for lithium batteries and if i could use them for the ni-cad that would be great just would like to know how to do it...

@@makdady66 Just putting a current limited, voltage controlled supply across any battery to charge it sounds like a nice simple idea which will sort of work, but if you want the most out of your batteries then they need to be charged correctly. Ni-Cads can be charged slow or fast. For slow charging the current is limited to 1/10th of the Ah capacity. So a 1Ah battery would be charged at 100mA. At this current when the battery is fully charged the internal gas given off recombines back into solution and gives off a bit of heat. This allows other cells in the battery to catch up and all be charged. The disadvantage of this is that it takes 12 hours to charge but you won't damage the battery. Fast charging needs to have a means of turning off the charge once the battery is full. When a Ni-Cad reaches fully charged the voltage changes from going up to going down. A Ni-Cad charger detects this voltage change and drops the charge current to a much lower level to give a bit of time for all the cells to equalise. Also the battery will start to get hot. Chargers usually have a fail safe temperature cut off as well so that if the fully charged detection failed the temperature rise would be used to stop the charging. Using the simple power supply charging method it could be possible to set the cut off voltage a bit below the voltage at which point it starts to go down, but the battery would not be fully charged. A common problem with Ni-Cads is that a cell or cells can develop internal short circuits. If it is a resistive short then it will still charge up to the full voltage but will not hold the charge for long. If the short becomes a solid short, then that cell will not charge and the battery will never reach full voltage. I use a circuit I built about 40 years ago to sort out internal short circuits. It is powered from a mains transformer. The positive half cycle charges a capacitor to about 30 volts, then on the negative half cycle it is discharged directly to the battery. This gives a succession of 25Hz short high current pulses into the battery. This clears the short circuits and charges the battery slowly. I hope this helps but remember, All batteries have a limited number of charge cycles and will eventually become un-useable. Having the correct charger will ensure the best battery life.

The list of items you need are in the description at the bottom of the video. Thanks for watching and sharing.

Take note, I have explained all that in detail in my follow up video detailing how you can charge lithium batteries too using the right cards.

I have already responded to you in your email. The power supply we have on our site has a few variation of voltage and Amperage ranges, if you have picked the wrong voltage, it's not my fault. I have sent you a copy of your order, which shows what you ordered, and a screenshot of what we have for sale, which gives you the choice of different voltage and Amperage range of power suppliers. However, although it was your mistake top choose a wrong power supply, I even stretched an olive branch to you as a gesture of good will by giving you 50% discount code to use on any purchase you want! If you made a mistake in ordering on Amazon, eBay or on any other website or platform, you wouldn't be able to return and get a full refund. I've been more than fair with you. Thanks for your comment! We have an overwhelming number of happy customers.

I ask people to not buy your products! Very shady business practices! I lost my money, I will not buy your products even at 50%,

Thanks for your comments, yes you're right. But please don't share links here as it's classed as advertising. The links at the bottom of my video is similar to what you are referring to. It will not give more current than required.

@@totalelectricaltraining I removed the link. Yes It's important to limit the charge current.
