Man! Thank you so much for this demo! Solved all my probles with the dam chargers. I was using a Hobbico (12V) for 12 V packs, but this Turnigy is much better. To power the Turnigy, i used an old Vaio notebook Powersupply, output 16V 3.9A. Thx again, man.

Making use of the kzfaq.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

Hello friend, I'm Wikkid or Danny and I wanted to thank you now for the second time, no it's the third. In case you don't have telepathy, I will rundown my thanks in chronological order real quick. First time I viewed your video you earned my sub after you help me get a deeper understanding of brushless motor controllers that I needed to upgrade my Bolt Pro. Kept watching other videos you posted and saw that you were running a high voltage cordless tool battery on your eBike. So when I found a 40v 6aH battery for $10, I just had to follow your lead and that Hart battery is still running as my girl's primary battery still. We both thank you on that one on #2. And tonight I'm looking to understand how to charge a 56v battery using a 58v charger and find out how the Echo smart charger works cuz it didn't start charging when I connected them directly together. I'm still looking for how the Echo works, but I saw your video about using a Teniagy charger to recharge basically any normally volted battery. I don't think you can pull 56v from a computer PSU without swapping a transformer or something. IDK how either. So there that's my 3 thanks I send your way. We have a lot of common interests and things we like to create and build. You live in Florida too? That would be starting to seem like fate was playing part of this, but who really knows. Oh and if you wondered where I got a brand new still in package Hart 40v 6aH battery, it was from a person I know who sells a wide variety of items at the largest flea market in the South East on a Wednesday. So now I'm going to see how much a variable Teniagy charger is and find my field multi-chemistry charger to see if it will work for such voltages. I revive lithium-ion batteries that people have run down too far and give them a second go round. Most people think they are faulty and sometimes they are. But usually it's the BMS or a single cell or handful of em causing the problem. But this is all prob things you consider childs play and are light years ahead of where I am leveling right now. Maybe someday our paths will cross and we can shake each others hand. I just wanted to express my admiration and send my genuine thanks in a wholehearted way, so I think I did that. Later, Wikkid.

second EVER like given to this video, I am SO getting one of those buggers for my solar battery bank. thanks mate, awesome info!

Thanks for breaking this down. Look forward to seeing the power supply video.

Fantastic idea, explained perfectly!! Many Thanks!

Great educational Video. Very easy to follow you. I have a few peak chargers for all my RC stuffed honestly didn't think to use one. . My craftsman chargers for my 19.2 lithium batteries must have gotten moisture etc in them as won't put out current. I also need to revive many older lithium 12, 15 & 19 volt Craftsman batteries a nd am going to try giving them a zap with one of my auto battery chargers unless you have a better way when they won't take a charge as they are completely dead. Thanks again and it's been years since I converted a pc power supply so looking forward to that video... Jerry

Wow excellent job 👏 you are right on with your information and I definitely learned a few things. I hope one of your other videos shows how to replace the batteries because it is very confined on space. Working on my soldering skull and hope to never pay the insane price for a Milwaukee battery again

I learned a lot watching this video - on to watch other of your videos.

Nice, I use an IMAX B6 to charge various drill batteries from different manufacturers. Going a step further, I have the IMAX connected to the 12 volt output on my solar power station, so I charge them up with a small solar panel. I found this video looking into the aspect of adding balance charging to the process. However, from what I've seen, apparently, very few drill batteries are actually wired up for the complete balance charging a B6 can do anyway.

Worked perfect for me! Many thanks!

Good job brother

Your video are useful from 7:27 onward

Hi random question, can you please tell how I can check each component in my Rugdoctor X3 to find which component or components is stopping my carpet washer from working please. Excellent video thankyou for sharing this.

If you don't have an original Milwaukee charger, this is probably the best way to charge as long as you keep the current low. Milwaukee doesn't charge through the middle pin as some have said. That is a temp sensor. The other two inner connectors are for communication. The board inside the battery does have some balancing circuitry but does so slowly. Rapid chargers would rely on the temp sensor and communication to pause charging if the battery gets too hot or out of balance. I'm not a fan of rapid charging anyway as it shortens the life of your batter pack. But if you are a pro and time is money, it's probably better to buy new batteries often than sit around waiting for yours to charge. I'm planning on building a charging station out of an old Dewalt case where each charger will have CC/CV buck converter with some type of temp cutoff. It will also cut off if I close the lid. That way you can leave them in there and take the whole thing with you. I'll use 3d printed holders for charging so I can mix and match. I wont do a video but I may do an instructable. That way I can get feedback on how to improve it.

Great video. Need something to do my 40V and 56V batteries as well. Anything similar?

Wow, this was very informative! Thank you!

Yeah, he is long winded BUT if you've got somebody who's not comfortable with doing something like this, it is reassuring. I have no issues with his method (which is what counts--his method that is) as I use my Triton 2 battery charger (for RC batteries) and as long as you know the capacity of the battery (hard to find sometimes as not all mfg's are forthcoming with these stats), you can use this type of charger with clips. And use your polarity tester (or something similar) to test for + and - as these are not usually marked on the battery.

The 'extra' terminals are there for a reason - Li-ion batteries are susceptible to overcharging and get HOT! Those terminals are for the temperature sensor to protect the cells.

Always learning from your videos, I didn't even know what the "S" meant,now I know Thanks! I just want to ask you,I have all 14v batteries but have two dead 18v batteries,can I hook up two 14v battery packs in series and jump start the 18v battery?

Nice! But what about balancing? Does makita 18v battery have balancing ability in it? If not than it will result a problem after a few charges...

ok cool, will also work for recupricating tool battery? its not the same

Very good video,we’re can I get a charger like that ? and will it change both Ion and nicad

Come back a few times to watch this, and thank you kindly for taking the time to film/edit for others. However, a question: Is there a decent diagram someplace for the wiring of a 5s battery used to deliver 18.5v? That is to say, WITH the balance charger leads integrated inside? I’m using An IMAX b6, which is essentially the same thing you have there. I also have the 5s plug, but just want to make sure I’m not screwing myself. As you say, makita batteries are terrible, and for some reason I ended up with about 15 power tools without chargers, or the chargers and no batteries. Am hoping to modify them all to take a universal. Just need to be sure of my attack plan for wiring. Any link is appreciated

Where can I buy this charger? Got rc truck battery pack that didn’t get a charger. This seems to make it a useful battery with this to charge it? So grateful,!if I can find one to buy

I have a Milwaukee v18 battery like the one on your counter but it won't take a charge from the factory charger. Have you ever tried balance charging the Milwaukee battery?

Any suggestion on charging the Hilti B22 22.6v? Does it have a BMS inside that takes care of the balancing?

There is no slit on my 18v ryobi one plus battery to put that little metal tabs in. Any suggestions?

Are those 3 extra pins on the 3s 12v batteries for Balance charging? 1ground and the other 2 are in between pos and neg for the other 2 cells?

Can you balance the cells with that? Thanks

Hey brother, I need some advice ... been subscribed for a couple years and enjoy your ingenuity and humor. Sooo, I got a two way radio that is super nice....actually 5 of them .... but no charger .... it's a 7.2 volt lithium ion battery with 2150 mah I think. What range of those transformers could I use to charge that if I cut the plug off and just put the wires to it. I don't think I have a 7 or 7.5 .... but I have a bunch of others ... so what Is ok you think??

Hi vuaeco, thanks for your nice video. Can you show us the terminal pair to charge Milwaukee 18V Red Lithium Battery (Cat no. 48-11-1815)? I don't know which pin is correct +/- connection to charge. I measured the voltages of these pairs: 16.5v/0.3v/16.0v/0.0v/mass. I tried to connect 16.0v/mass but it did not charge. Thanks a lot.

Hello Vuaeco, I am learning a lot from your videos, Do the Li-Io power tool batteries need to be balanced charged? I see you have another video (DIY Balance Charge Li-Io battery pack) Thank you for all the great information on batteries and charging them :)

How did you make the jumpers cables on the connection?

U know most turnigy chargers can change chemistry to Li Ion for the correct voltages. The setting shown here is for Li Polymer which no power tool uses I don't think.

I was thinking about I installed two 20v drill battery packs in my ebike now I'm not sure on how I can charge them at the same time anyways without removing the battery packs everytime

What about different battery chemistry, aren't charge rates different in last 20% of charge? How about difference in cell type, like 18650 or 21700, does your charger accommodate fo optimized life of battery?

Thanks.

0.5A is half an amp not five amps. Big difference! Charging at 0.5A is appropriate as chosen by the charger unit. Also, charging this way without using a balancing circuit is ok for a while but eventually the battery pack Will start underperforming as individual cells become less than optimized. The balancing circuit is there for a reason.

Can you please confirm that you dont need a balance lead to charge in series?

As far as I know, most Lipo battery chargers, at least smart chargers, require a balance port?

Milwaukee m18 won't charge on this way. Do You have any solution to charge milwaukee battery whith power supply whitch CC CV function?? I connect two outer pins + and - , power supply indicate charging whith 18,9V and 1amp but battery don't charge. Sorry for my poor english. Regards

I would like to modify my Makita battery charger so it can charge all kinds of batteries. Do you know how to do something like that? Could you show us if you know how to?

Good video, how can I get them little metal clips to connect to the drill batteries, you made them yourself?

Hi! Thanks a lot for showing this here, this is just what i wanted to do! Could you tell me if i can use the charge balancing feature of the Turnigy with the DeWalt batteries? Just need to find the correct pins, right? Thanks a lot again!

Have no idea whatvyou did aftercare pins went in. Where did you getvthe pins? What wires were used. Confusing.

Hello, With your method, you are connecting only the positive and negative from the power supply to the + - terminals of the battery and do not use any of the balancing terminals. For example, the Milwaukee red battery has 3 terminals in addition to the + and -. I tried your technique with my Ryobi 18V Li batteries. The tool stops working when battery is down to 18V. The battery has 3 terminals/ contacts marked + and - and third is unmarked (call it Y). The meter reads 18V (fully charged is 20.5) between each of + and - / + and Y. Nothing between - and Y. By your method, simply applying a charge between + and - or between + and Y should work but it does not. I applied 20.4V and the battery did not change. Looking at the original charger (I borrowed). It has 3 terminals corresponding to the battery's 3. When the charger is plugged in with no battery in it, meter reads Y as positive and there is 3V between Y to + or Y to -. Any one has suggestions? Thanks.

great

Can I charge Milwaukee 18v (non lithium) batteries in this fashion? I think I read something in the comments below that state you cannot. I'm curious because I just acquired a Milwaukee hammer drill and sawzall. Both have batteries but no charger.

Hey Man weird question the metal clips do they have a specific name, cant seem to find any anywhere.

Can I use sheep metal for a pin

You lost me at the power supply source. Does the turnigy have its own power? Does it plug in to 110 then output proper volts according to the settings you choose?

Why you did not try to charge it in balanced mode?

I have an imax b6ac v2 charger. And i m trying to charge a handycam battery, however i cant get it to charge on Lipo settings as it says No balance Lead connected. So i m charging in NIMH mode and its charging.

Thanks for vid- where does one get those terminals from...can I make one from tin can? I'm trying to recharge 20v L-ion mastercraft....

this doesnt work on my mailwaukee m18 batteries.. i got a milwaukee impat driver and battery for early xmas present from my mrs, but she didnt realise it didnt come with charger too.. I have an imax b6 charger, But each time i connect to pos and neg, it fails to charge, because the 3 middle pins of the battery are for the bus of the pcb...

I don't think power packs for cordless tools are balanced charged. They don't get the same use as in model aviation in which the model's power pack may be discharged in 15 minutes. Power tools can go for weeks without discharging the batter pack.

Won’t the cells become unbalanced if you charge it this way. Or is the balancing done in the battery casing?

My Turnigy Accucell 80W charger won't start charging my li-ion drill battery, excuse me but I can't understand how did you start charging under balance mode without connecting balance cable ?

Can I use the positive and negatives run wires to each battery and run them connect together to run to an outlet?

curious if any one can suggest the best way to run a imaxb6 directly from a 12v(battery) solar set up by passing the need for an inverter. Basically wanting to use it as a vehicle charger for a makita batteries.

aren't some of those batteried lithium ion? my sky rc charger has a separate setting for LiPo and LiIo

Hey, tried this with mine charging each bank & couldn’t get past the Battery Check from the Charger..... Any Ideas ???.. on a m18 Milwaukee

was this before anyone made 60volt batteries? my snapper SBA260V only has about 49.5 volts and won't charge in the charger, any recommendations?

So what’s for sale?

I have a Hilti CPC battery from a impact driver/wrench which I want to charge off of a UAC-50 model RC charger.I need help to identify what is the positive and negative out of the 5 pins. There are two paired together on the left and three together on the right.

Can you use this method to bring a li-ion drill battery back to life?

I have a 18v lithium Porter Cable drill,by chance will a20 v lithium battery work also

I totally would do anything to find a makita battery

How come it’s charged with the lithium poly setting and not one of the other lithium options?

i came here looking for a way to charge a cordless battery with a 12v charger which would be very useful but cant be done. what i dont get about this method is why go to all this trouble when you can just buy another charger for $20?

I just got my Turnigy Accucel 6, ATX power supply built, and a boatload of Lithium tool batteries, only to continuously receive a "BALANCE CONNECT ERROR". Please guide me . I want this to work. Thanks in advance.

hello.i have a 120v,14W power supply,the amp is only 1/2 amps. i want to use with my charger,will this work for my kobalt 18v Li-ion battery?,thanks

How do you balance? Just YOLO it I'm guessing.

Great video thanks for the info. Where did you get the clips at?

I have makita BL1850 18v 5.0AH, do I set my charger to 5s ? Thanks for vid.

Hi can u please show me how to revive & recharge my 6cell 7.2v rc battery pack?? Thanks

The content actually started min 7.

I have a Ryobi battery and it has fourth contact on the body. After I connect it to Imax B6, it charges for 10 seconds and then disconnects.

the balance leads?

Ebay IMAX 6 charger is 17 dollars thay work awesome and are cheap af!

Balance Charge is very2 Useful Charger, I Have Original iMax B6 I use that for many Type of Battery.

So you cant charge 36v hilti tools with it

Is there any chance of overcharging or does the Turnigy stop charging once the battery is full?

Anyone ever tried adding balance leads to their packs?

Excuse me man you seem to know a lot about this stuff I got my brand new terratek drill driver 18 v yesterday and it seems to be charging for ever the lights are still on maybe it's been 12 hours or more I've charged it it works the drill But why hasn't it full charged ??

Hi,what setting do you put the multimeter on?thx

Can I charge a 10.8v lithium battery with a 12v lithium battery charger?

HOLD ON THERE A SECOND .Before the first minute.... HE describes the 7th and 8th Batteries as being 12 ( TWELVE ) volts when they both have been clearly marked with 18 ( EIGHTEEN ) volts on the side, or am I wrong ?

since this is for charging lithium batteries only, please put lithium in the title. I came to see the reccomended charge rate fo old nicad and nimh packs.

Is this only possible with Lithium style batteries? What about NiCd and NiMh?

Is there a way I could email you or converse with you via discord or ? It would be greatly appreciated

I bought an IMAX B6 mini and I am getting an error reading "CONNECT ERROR CHECK MAIN PORT". Anyone have any suggestions?

What did you use for pins?

I am searching a portable source of power supply for operating a ice cream machine where electrical supply is not available.

Yeah...without any balance charging you are reducing battery lifetime so you loose money and it may be dangerous (over charging 4.2*3=12.6 but 4+4.3*2=12.6 too...). You can use this method sometime but not always. You can also buy a 5 dollars lithium charger with jack plug it will do the same.

thanks for nothing google. I searched: charge DIY drill battery "without balance charger" and I see this video which exact opposite of my search. I only want to take the junky low Wh and replace with 4 18650 in series. .. this video is good for the everyone else though.

Hi man. Like your video. Couldn't help to ask but are you Vietnamese?

How does it charge 18volt batteries with only a 12 volt input ?

Maybe you should have tested the batteries before you filmed so you would know which one needs charging.
