Prolong The Life Of Lithium-ion, Laptop, and Cell Phone Batteries > t.co/mK3KjJd0lr
Steve Willson Kujur Brother, I want to be a battery charger and take power directly from the sweet board and charge the battery
Quick and easy. Best part is the speed at which it is all delivered. Thank you for being quick with things. Its refreshing.
I have used this exact little switchmode module, they are really good BUT they are destroyed almost instantly if the input voltage is removed while a battery is still connected to the output. The addition of a reverse bias protection diode from the output positive terminal to the input positive diode will protect it.
Thanks . I also faced that issue. My buck converter was burnt. Need a reverse current protection .
Add the diode in output between converter and battery...
So a Diode connect the 2 output ( neg and positive) on the board ?
hey, I am looking to figure out how to charge my mobility scooter while it is operation. so I ordered some 12volt micro alternators and am now scouring the web for any pointers on charging. thank you your vid helps a lot, son.
Thanks for this wonderful tutorial - can you let me know If i can charge 2 batteries (12V) with the same configurations
Just made my own homemade charger. Soldering is kinda hard I need to practice lol . Thanks for this video.
You can use alligator clips or just try tieing up the wires or do some crude joining, soldering ain't really necassary for smol projects, but shouldn't be ignored
@@vinayakonimani7628 i got better at soldering but thank you.
@@TheCrazy243 cool
You work as a professional with science, creativity and mind 🧠 👍👍
I used this to charge my 12 volt battery on my Bluetooth boombox, works perfect. My fuses were blown on my volt meter and didn't work at first. I use a laptop charger putting out 19 volt and connect it to a 2.5 jack and then to the step down board that brings it down to 12 volts that I need. Thanks Steve
Sorry I realize this is old, but I have a question. What are is the 2.5 jack you add in? I am trying to picture what your saying but don't understand that part. Are you meaning you in-line a 2.5a plug in and then reduce the voltage on the voltage screw like he has? I have a Monster RR2 speaker and I am having a hard time getting it to charge, but I think it is because I am using a 10a 12.5v cord and it states on the back to only use a 15a cable? I don't think it should take as long as it does to charge. It has been plugged in for 15hrs or more and moved one light. That didn't last long at all. I recently purchased the battery so I had it checked at Advance and it is good to go still do didn't hurt it, so do I have to let it charge longer and if so I need to figure out something more practical charging even if I have to charge outside the speaker. It is very easy to access anyways. Thanks in advance, and appreciate your response if your able.
@@wanting2makethemoney always remember that the amps on whatever power supply your using has to be greater than the number of amps on the device that your trying to charge. And that's because amps are pulled out not pushed in like volts so when the device has met its required number of amperage it automatically stops drawing out anymore the device only draws out what it needs and thats why the power plug/supply your using has to have a higher amperage rating than your device. Hope that help. Good luck 👍
Tinkerer tip: Whenever you need to cut the plug end off a wire, always leave enough wire on the plug just in case you need to splice it back together. At least 2 inches, 4 cm.
TheHelvetican, and for this application he does not need the ferrite core on the power line.
2inches is 5cm
what is the ferrite core used for please?.. Thanks John :)
basically reduces interference caused by current running in cables. So without out it, if you took your laptop's power supply near e.g. a radio it would interfere with the radio station reception.
en.wikipedia.org/wiki/Ferrite_bead
These low cost, simple switching regulators are brilliant for this kind of job when a DC supply (of the wrong voltage but the right power is available) and I have bought many for many different types of project. Great informational video BUT ...
1. There is simply NO need to cut off the jack plug from the PSU at all. This is plain wasteful and reduces future flexibility. Simply obtain a suitable jack socket and wire THAT to the regulator instead. This means you can keep using your laptop supply ... for other things (e.g. other low cost voltage supplies) if not for supplying your laptop as normal.
2. When using this type of switching regulator one should ALWAYS fit a Schottky diode (or diode pair) between the regulator output and the battery to protect the regulator from probable reverse voltage damage when the mains is deliberately or accidentally disconnected before disconnecting the regulator from the battery. One diode ... a few cents and problem solved, circuit protected.
3. by implementing 1. above, the regulator can also be housed in a plastic weatherproof box together with a low cost voltage or volts/amps display available from eBay or Banggood or others for less than a burger, and can be left connected to a car battery in the car - set the output volts (measured AFTER the Schottky diode) closer to 14.4 volts and the output current limit to 4 or 5 amps for a large, wet tech battery e.g car though. A permanent connection can be made to a dedicated charging socket inside the vehicle cabin ready to just have a laptop supply plugged into it whenever charging is required. No opening the bonnet, no messing with croc clips just plug in, switch on the mains and away to go. Just remember this will NOT provide enough power to start a car, just to recharge the battery over a few HOURS! It's not an instant fix.
4. If you implement 3. above with a volt or volt/amp meter, remember to fit the meter AFTER the output diode otherwise your charge/battery voltage will not show correctly although the amps might (depending on exact meter type and circuit wiring). If you intend to leave it in the vehicle permanently remember to EITHER fit ONE extra lead input to the box - an ignition switched positive feed to the +ve connection on the meter, OR the meter can be connected direct to the incoming supply (voltage permitting) and because of the Schottky diode on the output there will be no power from the battery to power it either..
5. WHATEVER amps you wish to utilise, ensure the input supply can provide them, but remember though that although a 19v, 4A supply will have almost 80 watts available assuming the regulator is 85% efficient (they usually are, or better) then taking a conservative 80% figure ... 80 Watt x 80% = 64 watts at 14.4 volts = 4.4 A. 85% efficiency gives 4.7A and 90% efficiency gives 5A! How can you get more amps out than in? You are converting ENERGY not voltage so look at the power IN compared to the power OUT multiplied by the expected (or measured) efficiency of the regulator.
6. Finally, if you want to be able to charge OTHER types of batteries (e.g. rechargeable electric drill batteries, then simply replacing the two on-board trim pots with the same value panel mounted ones will allow you to set both Volts AND current EXTERNALLY so that your supply can be set for constant volts (lead-acid charging) OR constant current (NiCd or NiMh) but be wary of using it to charge Lion or LiPo batteries/cells due to their much more complex charging criteria. For 18 volt batteries you'll almost certainly need a higher voltage input than 19v. It MAY be sufficient to use 24v but I'd expect you to require a few more than that even ... say 26 to 28 volts.
+Bob Lewis very very informative comment thanks for this information
nice
Just to show I wasn't just trolling the other day with my long comment above I was actually awaiting a couple of parts for my own 12v lead-acid charger based on exactly this idea. The working (but still incomplete) charger is now in use keeping my vehicle battery topped up. Unfortunately, the meter I received from China quite some time ago doesn't appear to be able to display amps so I am awaiting a new one. I also have ordered another regulator since the ones I currently have (several) do not have any current limit setting pot. Consequently I set the output volts a bit lower than where I'd like them to be at 14.1v open circuit and it is keeping my battery very nicely sat at 13.8 to 13.9 with a trickle charge of around 360 to 370 mA (measured with my mutimeter).
Another thing I'm awaiting is a pack of heatsink adhesive pads so that I can properly affix the two heatsinks I have, to the regulator chip. The one finned heatsink you can see is basically just stuck down with silver heatsink compound! You should also be able to see the black "transistor" like object just next to the regulator which is actually the dual Schottky diode I mentioned should be used to protect the circuit from reverse voltage from a still connected battery should the input power be lost or removed before disconnecting the battery itself.
As I mentioned I have the meter connected to confirm the battery voltage but I had a rethink about what I said previously and I power the meter from the incoming supply rather than the battery output as that prevents undue drain on the battery once power is removed. However ... If a 9v battery e.g. a PP3 is connected at the input it can just about power the meter but not provide sufficient voltage for the regulator to operate and the meter would then show the true battery volts. A working ammeter would confirm this of course.
I had to come back and re-edit this due to a complete shambles with Google providing links that didn't work so apologies to anyone who has been confused and also to anyone looking for the other replies i made to try to post pictures - IO deleted those and instead put all the pictures into a public Drive folder: goo.gl/Rn2dXY which hopefully all can access without problem
Bob Lewis make a vid of how to make a 12v fan for a boat please...that would be greatly appreciated as u seem to be very knowledgeable
Jerome Daniel sorry I'm not certain what you actually mean. Is the "boat" 12v or 24 volts? if 24 volts and you need to use a 12 V fan (or fans) then just get one of these little DC to DC regulators from eBay, set the output to 12v and connect as many fans as you need up to the maximum supply capability (with and without appropriate heatsinks as stated previously). if the boat voltage is 12volts already, then just connect your fans direct to the 12v supply.
Thank you so much. Now I can charche my solarpanel batteries in wintertime too. Wow. And so many thanks that you show how to do the connections. Really very good. 👋👋👋👋👋🙋🙋🙋
Thanks for the fantastic solution. Please advise for three queries.
1. Does this unit have auto cut off when charged ?
2. Can I use this option with increased voltage to charge a 24V SLA battery also? If so what changes do I need to do?
3. Any tips on how to build a case to put these into a secure charging station?
I would glue it in a clear rubber made container that I could drill holes into and then water proof the holes.
Brilliant video and on the basis of that, I purchased an identical module. alas although I wired it up as shown in the video and the laptop adapter was showing 19.5 volts on multimeter. the red and green leds were lit on the module and despite turning the voltage adjuster both ways. it wouldn't change from showing output of only 1.49 volts. I will be returning the module and hopefully the replacement will work as shown. I raise my hat to you sir on a clear and informative video and only wished I could say yes it works for me.
Why not setting Amp to max with DC supply so the charging is faster? I enjoy the video and I have learned a lot from you. Thank you.
Just built it... works great.
Thanks for the clear, simple video.
We are wanting to run / charge a portable device powered by a 12v, 7A/H AGM battery, from a car cigarette lighter plug, and this looks like the perfect circuit for limiting Amps and Volts to safe levels.
My question: Is there a built-in function, or a simple modification for disconnecting the load battery if its voltage should fall below the safe minimum for gel batteries? Some customers will likely take the running device out of their utes into the field and may forget/fail to plug it back into the car in time, thus compromising the battery.
thankyou!!! finally someone who posts this! i wanted to know for so long but this is amazing!
+thekleinevandaal Thanks glad to hear that

steve what is the step down module's number or designation
LM2596 cv/cc
Ruan Kemp we
Bro easy tutorial and easy to follow bro you are amazing
DON'T YOU JUST LOVE RUclips. THANKS MATE
Thanks !! This is really Helpful...I will now reuse my UPS battery which was lying idle with me for 4-5 months.
Do you have a circuit/process for charging Laptop(20V 2.25Amps) or Mobile (5 Volts 1 Amps). If I can use my UPS battery as a power bank??
+Venkatesh Narayanan yes you can don't worry I'll come up with a new video make sure you subscribe to my channel for feature updates
Thanks...I googled for a while and found in Amazon.in a step down Unit that should work I think. Its INR 93.00
www.amazon.in/Ultra-small-LM2596-adjustable-step-down-Converter/dp/B00LTQU4EQ/ref=sr_1_1?ie=UTF8&qid=1494102001&sr=8-1&keywords=Ultra-small+size+LM2596+DC-DC+3A+adjustable+step-down+power+supply+module%2C+DC-DC+Buck+Converter
Venkatesh Narayanan I know this has been a very long time so probably no longer matters but while yes that one would work it only allows you to adjust the voltage it does not have the adjustable amperage. And that is very very cheap price for those I paid $5 usd for one unit similar to that but it does have a built on voltage monitor screen so I don’t have to use a multimeter.
Thanks I have 3 old power backup batteries, the charging section is toast so I need some thing to keep them charged, they power my Ham radios when we are out in the field.
can we use this for Lead acid battery ?
Thanks for the video, I've been wanting to make myself a boom box, and your videos help me.
+Stratton Foster Welcome
i have two old laptop chargers. I can't wait to order those modules.
thank you. you talked!!!!!!! where can I find the thing you was adjusting??
www.amazon.ca/Yeeco-Converter-1-25-36V-Regulator-Transformer/dp/B06X6BTRBK
Thanks a lot for this, you have shown me a way to safely charge my SLA battery without destroying it due to over charging.
1. Can this be used with a 30V adapter laptop charger to charge 24V batteries?
2. Is there any way to install this component on some standard case so that we can use it for normal use ?
3. Any way to take care of the heat generated - anyway to attach a heat sink?
Thanks a lot.
1 You need to check the concerning IC'S datasheet to see if input voltage of 30 can be used. I think this one is 32v but still check.
2 Yes but it depends on creatively ruclips.net/video/BonGGUmEbS4/видео.html
3You can find small heatsinks exactly for these modules on eBay or equivalent.
Very kool and thank you...is there anyway to make the door handles outside able to shock someone .like at night if im sleeping and my dogs sleeping and a group of people try to break in and they grab my handles and get a good volt of good old Mr electricity knocking them down and souoing themselves is that possible??.its never happened but I think it would be a nicec touch I mean its mine so let me know my friend and kickass
Thanks for a very cheap and easy way to make and adjustable lead acid charger.
Someone please buy Steve a wire stripper for his birthday. It might save him a nasty injury from a craft knife.
Thanks dude !! i have made a boombox 100watt. And i was wondering how to make a battery for it. can you tell me does it heat when it charges , and can i use 18650 battery with it to charge them ?
You can use the Imax b6 multifunction charger for this as well, but if you get the adaptor one, you need to buy 15v 5amp adaptor for this.
The b6 charger has protection features that this module does not have.
what about an overdischarge protection? Excellent video!
+Andrés Alberto Pacheco Herrada see the video in the description
You'r presentation is clear and helpful
Thank's a lot
I think you should study what's the use of DC sockets and how to remove plastic coating from the wire using wire striper
Very nice and simple video, in fact the device that you have used made the video so simple, from where you have bought it and what price?
Blagodaram za ubavi i korisni soznanija!
Thank you!!! I will make one vs buy one.
Hi!
Nice and clear explanation and good vide.
My question is:
Is the 2A charging current not a bit too much for a battery of 7-8Ah?
I would say a charging current like 500-600mA could be better.
IIRC a lot of fast battery chargers use anywhere from 1-4 amps, just because its quicker to charge the batteries, but these chargers also have saftey auto shutoffs to protect the batteries.
I have seen a diode connected in series with +very terminal and battery which doesn't allow reverse voltage from battery which may damage buck converter. Is this necessary
sir i have question i want to make 36v improvise battery to my scoot?
I Google wanting to know how my old car charger works, but I found this instead. I need me one of these step down modules! I have a bunch of old laptop chargers too. Must also be far more efficient than the old transformer chargers.. Even though mine is 50+ years old it still keeps on going. I just had to remove and bypass the 6/12v switch so now it's 100% 12v but I really could use a backup charger. Better yet I should build some solar trickle chargers.
And I just realized it's a lithium charger..
great Video Sir,
Is it possible to apply the same process with a 48 volt battery charger too? I need to charge a 4x12v Battery Pack
Salute!
What's the name of the electrical piece you put in the middle to change the voltages and amps through it ؟؟
Great job👍👍🧠🧠👍👍
It took awhile but read through all the responses and would like to confirm and ask a question(s).
The order of disconnect from the battery if it is important is what battery first then supply?
Never looked at the inside of my multimeter so have to ask what does the input look like when connected in current measuring mode?
The diode you speak of for preventing the Solar panel from acting as a load at night, if used for this purpose, is in series with the positive side between the solar panel and battery?
My battery is 5Ah 12V.
Marking on the battery
Standby use: 13.6-13.8 Voltage regulation at .75amps
Cyclic use; 14.5-14.9 Voltage regulation at 1.5amps.
In my case, the output at the battery for this charging device should be 14.5 to 14.9 and set
the current to 1.5amps.
Thank you
gute Arbeit, Große Hilfe Danke und Grüße aus Germanya :-)
Good work, big help thanks and greetings from Germany :-)
Those small 12v state 14.4v to 15v to charge and 13.8v to maintain charge.
Could I safely connect (same type battery) directly to the 19v charger for say an hour just to put some charge back into the battery?
@@nedcramdon1306 Maybe nothing would happen, but 19v would not be safe. Maximum safe voltage is 15v. Anything over that and electrolysis of the water in the battery may happen.
BRILLIANT BUT WER DO I GET THE BOX TO PUT IIT IN SO I can Safely use it
Thank you Steve, I am so happy for your prompt response.
Can you pls give me a detailed description of how to accomplish this? I am a novice in this field; but I can fix it if you give me the necessary me guidance especially concerning the installation of a diode.
By the way, will this setup require an inverter for the laptop charger to pick up the energy coming from the solar panel?
Thank you in advance.
+Muhammad Salau yes you need a inverter or a boost converter to boost the 12 v
Connection
1. Solar panels got 2 wire negative and positive
2 . Converter got 2 input and 2 output
3 . Output directly goes to battery okay?
4. Input - connect solar panel positive wire to input positive .
5. Input - connect Solar panal negative wire to a diode before connecting it to input negative .
got it ?
help, I have a large 24 volt lifepo4 battery in my camper but the camper is 12v /13.8v. should I keep a 12v/13.8/ battery charged with a 24 to 13.8v stepdon or just get a giant 13.8 step-down and have no battery?
Thanks alot. Why all guide video creators are indian 😊😊
Is it capable of charging 12v 7ah lead acid battery?
If yes, then what voltage and current should I set so as to charge my battery as soon as possible
Charging voltage between 14.4v and 14.Safe charging current is 0.1C.That is 0.1*7=700 milliamps for a 7Ah battery.You can increase the charging current upto 2 Amps,but that will heat your battery and reduce its life.
what is exact name of the step up and its amperes and voltage mention so i can try build my own.
In the description
I find it astonishing how u didn't really use the wire stripper part of that stripping plier, (yes yes the wires outer covering is pretty thicc but u could at least create marks and later use the knife). Anyways cool.
Nice video!!! If there’s a device that runs on a 6V 4.5 AH SLA battery, isn’t it possible to take it out and connect the device leads to a 6V AC to DC power source and run the device through an electric outlet without the battery?
If so should any consideration be made to the Amps of the adapter to be used or any 6V adapter would work?
good charger circuit
[Tutorial] DIY - HomeMade - How To Make RC Vaterra toy very simple
Hi great vid! And great to see how you did the setting upTHANKS. I blew my meter in Amp before so were a bit nervous! I want to ask why you leave on cable the "lump" by the plug on charger? Has it any use? Seems a bit in the way. thx
The “lump” is an inductor.
Inductor: They are used to block AC while allowing DC to pass; inductors designed for this purpose are called chokes. They are also used in electronic filters to separate signals of different frequencies.
Wow, this is an awesome creative video I had a lot of fun watching it. Thank you for sharing with us! I'm a new here, big like 👍 and stay in touch ❤!
Thats amazing . Can you to help to me I would like to make pover suply for my rib boat electric pump where is 12V 15 am max .I was everywhere in shop but they has max 10 am batterry charger . But dosnt work supose to be not charger , just power suply . Do you have some idea how to similar easy way as is on this video ? Thank you so much . Can you also send to me where I can all buy . Thank you Ladi.
+Ladislav Zadych so you need a 15amp right?
Steve Willson Kujur yes thats right Steve but no more than 15 amp , becouce will damage my pump.
Very good, simple and efficient
Great video!!! Where did you get your battery from or where is a cheap place to get one? Doing a project that involves powering a water jet with a 12v battery.
+Daniel Keku you can get it in local shop and do a Google search is a nice idea .
You used DC to DC Buck converter which can give 14V 2A is that a constant current source because considering property of lead acid charging its current remains constant for a while and then it decreases to around 0.03A ?
Can 12V 2A SMPS will suffice to charge 12V Lead Acid Battery?
Sir DC to DC step down circuit
iska kaam kya hey kya krte hey yeh circuit
I have been thinking of doing this, but do you need a "battery charger" or can you just use a power supply if you have a overcharge protection module going AFTER the buck converter?
can i use LM2596 step down converter which is without ampere adjustment and ampere is 3max
can i charge NiCad batteries with it too? I have a Black and Decker 12v powertool set
if i set 14v and 2amp current then how many hours i need to fully charge a 12v 7.5Ah battery?
Thanks for nice video
3.75hrs
Hi I have the same step down module. When I plug in the battery to charge I still get the red led along with the blue.
What does the red LED mean?
Obviously I'm doing something wrong because on the video you only get the red when you're short circuiting measuring the Amps and it goes to only blue once you plug the battery
Hi. Nice video. Where you get that adaptor intalled to change the voltages values?
Thank You Dear it’s worked 🎉 😊
Dude I've 12 volt landline charger connected to a 12 volt battery. Any home alternative (I don't have multimeter) to check if current is flowing in the circuit.
You can buy a really cheap multimeter from Harbor Freight (like $7), or whatever hardware store you have nearby.
Can I connect the battery to the OUT + ,OUT - of DC to DC step down converter directly?
Assalamualaikum
Bhai protection k lie diode zarori h k nai

Thanks for the great video. I have a question about a similar subject. I live in an area where there is a constant breeze and want to build a small wind generator. I thought it would be nice to charge my phone from this generator. I am new to electronics so if this seems like a silly question I apologize. Since the power being stored from the wind generator would fluctuate with wind speed, would that harm anything you are charging? Sort of like a power surge. Or are there things you can add to avoid such a situation? Thanks
Don't use the wind power directly. Rectify and charge a battery. Then use the battery
3:14 how you manage to measure the current directly connecting to the meter? As I know I have to connect on of the terminal to the circuit via multimeter to the battery or power source. Can I measure the of an ac adapter through directly by connecting to a meter?
+Sakhina Khatun no you can't just connect it to ac .
i did because this dc to DC converter capable of doing constant current that's why.
Good video, but you are feeding too much current into that battery. The initial video of the battery, shows (on the actual battery) Initial current not exceeding 1.4A.
Why set it to 2Amps? This will damage the battery.
can we use this for Lead acid battery ? I asked this question from aliexpress link which you shared , they said it cant used . Any reason ? then didnt tell me the reason
i have 4 12v 22ah batteries that i run in a series to make a 48volt 22ah battery pack for an ebike tricyle.....currently i have to break up the series and then charge each battery 1 at a time....is there some way i can make it so that 1 charger does it all and all the batteries get the same charge level ?
Is this have auto cutoff as you have said when battery is fully charged green light appears i want to know that it will stop charging battery or not.
hi, I have battery rated at 12v 4.5ah, with constant voltage charge of 1.35A MAX, this voltage charge means I have to adjust this DIY charger to 1.35aH and not to exceed beyond that? hoping for your quick reply
Bro you have 7 Ah battery and 2 ah power for charge how long will it take to charge?
Don't cut the jack, use an adapter connector. And you don't want to move the position of the multimeter all the way from DC to A while attached. Good video anyway.
+Jeswen Titomn yeah I know i mistaken
btw thanks
Does it have overcharge battery protection? When the battery is fully charged will it stop charging? Or ill have to unplug it?
Hi Steve...i am trying to charge a 12v 7ah battery using the XL4015...i set the XL4015 at 13.5v and at 1.4amps..however when i connect the 12v 7ah battery to the XL4015 output both the red and blue lights up at the same time...i tried it on another 12v 7ah battery but the same thing happens...both the red and blue lights on the XL4015 lights up at the same time...what am i doing wrong?...i am using a 19v 3.42amps laptop power supply as my power source...please help me.
Very nice vedio.... How much the charcit? And where i get it?
This might be just what I am looking for, thank you, Can I use this method to charge my 12v 3.2Ah sla battery and if so what should the voltage and current settings be?. Thanks again, john.... :)
+John Berry 13.5v and 700ma (0.7a)
Ok thank you very much.... :)
Will the charger with SMPS work or without SMPS?
Sir if the battery full charge then the green Led will on so sir it means that charger stop charging the battery automatically or we have to disconnect the charger. Please Inform Sir
Is it constant voltage or constant current method of charging ?
Hey friend what do you call that device that you connect in order to step down the voltage?
Thank you for sharing this worty work. I have a question : i dont know why you put the voltage on 14V ? isn't that dangerous for the battery ? it is obvious to put it on 12V because the maximum voltage of the battery is 12V no ?
google it and you'll get some information sorry i can't make you understand here
Battery will be about 13.8v fully charged. Thats why he set the voltage to 14v.... :)
Does dc dc step down convertor automatically stops the flow of current after battery charged? I guess it does not. After battery fully charge its voltage will be 13.5-14 volts. The circuit must be cut when the voltage reaches the desired value.
After the battery is full, the energy of the battery should be automatically cut off.
Hey this is a great video what a task is this converter will stop when the The charge is full I want to make sure it's not going to overcharge the battery to make sure there's not gonna be anything dangerous please let me know thank you
?
will it over charge ?
+yan. yan not at all
so it will cat of when the charge is full ? i dont need to add anything ? beside Battery over-discharge protection
?
After the battery is fully charged does the charger autcuts the supply?
Can this converter be used for a 24Volt Battery bank? Great video by the way.
+Opposite Worlds yes for sure but you've to do some modifications .
something like .
30v input voltage.
and set the output voltage to 28v .
and current as needed
Thank you.
I have a 12v charger came with a monitor. The monitor is not working. Anyway in my case i think i should be ok to use the 12v charger to charge 12v batteries or i still need that controller thing?
I was told the ideal charging voltage for charging a 12 V battery was around 18V and also to keep the current below 500 mA to preserve the health of the battery anyone disagree ?
What amount of current is suitable for 12v 18ah battery
very interesting VIDEOS thanks bro
