You are a very cool guy , I like how ou speak, you speak slow and clear and I like this style of videos not many people speak and make videos like yours video. I appreciate your time you spend to teach us. I will put your video in my list with the favorite videos in youtube.

Finally! Someone who explains the basics of charging a battery with this unit so that even the most rank beginner (me) can understand it. Thank you so much. ! Best Regards.

I must say, that is a quite compleat explanation!! You are certainly more advanced in electronics knowledge than I am. The Calibration information is extremely useful as well. If you're still responding to this old Video, I could really use some help!! I just got a "fake" B6AC... I charged a 7.2V NiMH Battery perfectly. However the second time I used it was on a Lipo, my very first. (And I've been in the Hobby for over 37 years) I plugged the unit in, and connected my 2S Lipo Batry. I fumbled through the Menus, but couldn't get it started... I then unplugged and replugged it in. Now all I'm getting on the Display is 0.00v 0.00v, 0.00v 0.00v, 0.00v, 0.00v The Buttons do NOTHING. Turning it off and on, leads to the SAME Display and no working buttons! Did I do something?? Is there anything I can do to mend this? I hope you can help me.

Thank You for posting this. I bought a knock off and found the rate/voltage off from a known battery. I did not know I was able to calibrate (Had not read the instructions if it even states it in them) the unit. Knowing this I will now pull it from the box and begin using it too. Again, thank You.

I've been using a fake for years!!! Thanks for showing me how to calibrate it

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

8:25 I don't even own a balance charger (yet), but appreciate that you don't just leave people who have knockoffs to twist in the wind. I'm sure many knew the risks, but couldn't afford a hundred bucks for a better unit (I'm especially thinking of those using e-bikes/scooters/boards/whatever as primary transportation) or received as a gift from someone who didn't see your vid! You're a gem.

Best review of anything I've ever seen on the tube. Thanks

Thank you! Very informative! Well explained and simple so anyone can understand. I’m glad I got the original...

Great comparison, very informative. I cannot however get the calibration button combo to work. My fake charger is one without the built in power supply, perhaps it does not have a calibration option. I did notice a misreading of the voltage and would like to calibrate it. I'm also wondering if it is worth upgrading some features to like of the genuine model, e.g swap to thicker cables, increase air flow vents size and other similar features, or leave it as is?

Nice video. Thanks. Came across it troubleshooting my charger which shows discrepancies between (a) current reading and the corresponding rate of increase of the capacity reading and (b) current reading on the charger and on my multimeter by a factor of 2 (!). This is when using a discharge program. Initially, I hadn't even considered that the unit could be fake, because I didn't realise how common this was. But having seen this video and others on the same topic, it was instantly clear. I then opened the unit up and couldn't believe my eyes when I saw that the case of the AC adaptor was cut open to be able to get the wires out. All in all, the thing mostly works for charging and balancing, but the large discrepancy on the current reading makes me a bit uneasy about the safety of the thing...

I 2nd that. Good on you mate , at last somebody covers what you really want to know. Straight to the point knowledge without all the crap. Thank you

Thanks! That really helped me to choose before buy it. I'm buying a V2 version which is an genuine SkyRC one!

Modern youtube reviewers should learn from you how you review a product with such details and information Great job, Sir.

thank you for such a well explained video. Very clear indeed. I didn't even realise that these chargers are a copy/fake of the real brand and now you have explained the errors with the copy version I have decided to spend some extra money and buy the real branded version. The copy/fake/clone what ever you like to call it defeats the whole reason for spending out on a professional charger and no longer using the cheap chargers that come with these rc models.... Even though the branded one costs almost twice the price I would sooner pay out and know the build and safety is far better..... Thanks again, Regards Steve

Great video! Incredible differences that sure make a difference. One thing I would change is the 18650 you're using for calibration, that one is fake since 18650 can only go to 3600mah due to chemestry and material constraints. I would you a well know name brand and quality cell.

I would imagine the white stuff you call heat sink sealant is probably just paste to keep the smaller power supply from sliding. I took my fake charger apart and it had the larger power supply and no paste on it. (I didn't check the resistors you pointed out) This was a good video to watch. Evidently the clones (fakes) vary on components used to build them, so if you buy one, it is probably a good idea to test it before turning it loose on your batteries.

i want to mention that there are different versions of the fake out there. is far as i can see you have version 08 as you can read at the pcb. i have a version 1.50 with atmel chip and larger power supply that fills out the space, but there are also version 2.0 with nuvoton chips out there. mine works well after calibration but actually i trying the cheali charger fimware.

thanks-bought the cheap b6-it did not last more than three charges and started acting up-have an original b6ac on the way-ur vid taught us a lot-thanks

Very good tutorial. The calibration was well explained.

Thanks so much, very helpful! Even more so now that I realize I purchased the fake totally unaware they existed. I'll follow your instructions and calibrate and test if it's rubbish I'll try and get my money back.

Thanks for the good explanation!

Thank you for the callibration tip - also works on my Hype-RC knockoff. How ever.. I've noticed if you callibrate at 5v f.e. it's way off at 12v and vice versa. Not good if you charge batteries with different voltages like I do ..

Thanks alot was almost gonna buy a fake it had gold writing but different lettering/printing on the front . thanks again !!

Thanks for the info just bought one of these. It arrives tomorrow. Ill know what to look for. Thank you.

Hi! The lack of a fuse concerned me. Could we install one of our own? Any pointers would be greatly appreciated!

Hello I wish I would have watched this before I ordered the fake one... But thanks for showing me how to calibrate it. Hopefully once calibrated it will work well. Very good video thanks for taking the time.

great job, thank you. love to see that there still are appasionate professionists like u

Did SkyRC make a previous version of this charger? I'm asking, because mine has the same lettering on the front as the fake one, but it has the SkyRC laser sticker on the back and came in the same box as the real...

Hi, thankyou so much for this detailed teardown. it prompted me to do more research, the multiplexer that sends the voltages to the atmega is very often faulty (amongst the other things that can be faulty with the clone) But: if you can replace that, it gets A LOT closer to reading the actual voltages, and ideally, eliminate the overcharging problem. it's a 4051 multiplexer. it's under the screen. I hope someone can figure this out without pictures.

great video. calibrated my charger. actually surprised to find mine was fake as this charger was bought in a walk in store I presumed sold the genuine article.

thanks for the information , I just bought one recently though I haven't received it yet and I will check details once it arrives

Hi , Couple of questions if that is ok 1, once it finishes charging and beeps , you have to turn if off manually or it carries on charging ? 2, Would you know if tablet and laptop batteries can be charged and tested on this ?

Thanks, this enabled me to calibrate both my chargers.

Didn't know this unit could be calibrated. Thanks!

Great job on this video,.Glad you demonstrated the calibrate function too. I just sub'd, and greetings from Vancouver Canada

Saved me some money on a future mistake. Thanks and greetings from Texas.

Need help I am new in this field I have two questions 1. How much time it takes to full charge 3s 5200mah lipo 30c? 2. It says 3.7v on battery as wel on imax charger menu, but it goes to 3.84v and sometimes 4v is it safe or normal?

hello, unfortunately i did not know about fake chargers when i purchased my used charger. so what components would i have to change to make a fake one read the correct readings. also i have since found out that once it has been calibrated, you cannot get that calibration option back, have you found a way to get it back????? looking forward to your reply.

Hi, you've described the difference between the two chargers but how do you know which is the fake,maybe the fake is the better one ?

hi.im hoping you can help..ive just seen this video. only to find i cannot do as you do .. ie it will not let me in to make changs . but when i set the program from lipo to liion the meter did not move so i put my avo in place to find the bat volts were 4.21.. but display is 4.10. and did not move.. you might like to try your self. atb tone.. p.s. i tryed on the two new chargers and my old one . both the same..on 1s

What an amazing and informative video! Thanks so much. Can you tell me please? Can you calibrate with a battery that's not fully charged as long as you know it's voltage obtained through a multimeter?

Hello prof, can you tell me the imax can modif for fature mode motor brush? Break in.. same like thunder machine or antimatter

Which one should ı buy IMAX B6 mini or IMAX B6 V2?

so, is the knockoff a good charger? should i go for it? i'm currently unable to source the real thing... also, i'm assuming this is 'smart enough to leave charging safely overgnight? thanks

very good review, interesting side note some of the later copies did away with the calibration function something I thought was essential to have

boa noite, amigo! parabens pelo video, sou brasileiro, muita coisa eu compreendi porem algumas não, minha duvida é a seguinte : o funcionamento do IMAX B6AC fake é semelhante ao original ou nao é confiavel? obrigado

hi thanks for the video. I am having garage and i want to add hybrid service . So, what is the best hybrid charger do you think in the market for Nihm batteries (Toyota&Honda). I would love to hear from you thanks

Hope this don't explode with that tiny PSU will have to devise a case for charging things in my room, thanks for showing me how to calibrate it!!

impressive and professional. Thank you Sir for a very educational clip.

so you can actually use the fake charger to charge your airsoft batteries, and it's safe to do so?

Dear Sir, thanks for your effort resulting great, comprehensive and helpful description.

I have two of these, had no idea they were fake! I cannot get either of mine to go into calibration mode, any help would be appreciated.

Thanks: good video. I have a fake, bought from Ballistic Performance Components and they added their own sticker to the front. But mine is fake: obvious from your video. It doesn't charge a 4S L-Fe battery: the charging cuts out at 3.25v/cell, instead of 3.7v as claimed. So I only get it to about 20% capacity. Any ideas if it is possible to change the settings? Like I see you can calibrate it: that's not in the manual I got, nor the manual from the MAX B6AC. So maybe there are more "hidden" functions. Thanks for the video.

Hi,I calibrated the (fake)unit as you described.My battery is a 4 cell,2200mAh,14.8v.I have inputted all the correct values,but when I try to charge the battery,i get warning beeps and the message,Low Voltage.What should I do?Thanks in advance.

Thank's for the video, i just bought a fake and i remember watching this a few years back revisiting,now i see why my "stop" button is less tactile than other 3 new out of box today, looks like i need to complain/refund.half the quality half the price to original unit .LOL..btw seems they have changed firmware or something as it's no longer easy to calibrate like you show..

Is there a way to use an Power Supply to calibrate ? Tekpower TP3005 on Amazon (not my, but similar) I do not have a good multimeter. Or is there a other way? With an 7805...or is this too imprecise ?

I'm glad you didn't just say fake and toss it.. Nice review and setup even for the *cough* clone.

I also noticed the smaller electroytic capacitors. But what is the difference in price between the two?

Gracias! Muy Buena información. Now i know that my imax b6ac is fake, but thanks for teach us use the fake one, and calibrate it.

Hello, congratulations for the very interesting tutorial. I wanted to say that I made several attempts following your instructions to the letter for the calibration but, when I turn it on, the calibrate screen does not appear, the lipo charge screen appears. Did I do something wrong? Thank you

I did not know they made 2 different types. Thank you for the video and information.

Hi Louis, first thank you! I just bought one and tried the calibration, the display shows differently with 6 values at 0. Are you familiar with calibrating in this case?

man you are very good teacher ...learn from you i used, to do fix electronics in my country tv vcr all kind but i stop like 16 years i feel happy when i saw your equipments lol let me know from were to buy original one do you prefare separately or combination means with out transformer or combo like you have in video thanks

What are the small white connector on the side , for balance charging , called ?

Thank you so much for sharing this knowledge , it is very informative to me, wish you good luck & e safe.

tried to do the calibrate thing like you did but it does not come up have a knock off

Hi there.. Don't know much about batteries chargers etc, but my son has a xtar vc4 and was hoping this type of charger may be better for him, what's your opinion on this, batteries are for his 9v drill etc (converted) and random batteries he has floating around e place ...?

Great review. Thanks for showing us the difference is those two products. very interesting

How to calibrate the balancer? The second cell constantly shows too high a voltage, no matter which battery I connect.

so buy the clone one, change 2 resistors(optional) and calibrate done deal. way cheaper than skyrc wants even if you can find one in stock. set maximum charge to 4.1 volts to improve battery life (long term) and prevent overcharging. and you can always cut a hole in to the case and add a fan which i will definitely do even with the original one.

between the real charger in the fake charger, how long can these two chargers can last before they have to be replaced? At some point these two Chargers will no longer be able to balance the batteries out properly?

on the 17:00 minute of the video you can actualy pres enter and the LiPo text flashes,then you can change it to LiIo Life LiHv

Did anybody tried to see how much current can psu push? Had no luck finding online except that psu is really bad and should be replaced with laptop brick, i burned my clone so im thinking is it worth to get b6 again or b6ac

Great, thanks for the heads up as I am in the market for one of these.

amazingly in-depth. but i would have liked to have seen a balance demo

Nice work! Can you tell me if it´s necessary to calibrate the original one? In version 2, the combination of buttons when powering on, takes to a "system is updating" message. Thanks!

The capacitors on the genuine look larger.

does the "real" unit come with battery plugs?

i just bought the SKYRC B6AC V2 and it powers up then powers off... if I let it sit awhile it powers up and works for a few minutes then powers off... I'm suspecting a bad power supply... but while Im checking... can I use the DC plug to a deep cycle 12v /60amh gel battery for a wheelchair?

Thanks for this, just nearly bought one, looks like its a fake so well dodged.

Good job, I've never seen anybody else do the calibrations before

When you were setting your voltage wouldn't it have made more sense to go a tad higher than +15? I'm just guessing but 4.17V would come in at ~ +20. So maybe a better setting to save would be ~ + 17-19. Basically just one click down from the 4.17V reading

can I charge 2s or 3s or 6s of 18650 if I connect only + and - wires , without balance wires ?

A very good review. You are a professional. Thanks a lot.

Just bought mine and it does not match either of your boxes. It does not have gold printing and it does however have an authentic sticker on bottom. It did say it was not fake on Amazon. It works like a charm and I am not going to open it. :-). Thank you for bringing this to everyone's attention. I think the company just changed their printing that's all.

6:04 I wonder if that's because 1 lb. (or 450g) is often the magic number for cheap shipping. Hmm...

Very useful guide! And what is the difference in price between two products?

Very nice comparison. Now i understand why I got the genuine instead of the knock off =)

Informative, nice. Sometimes 3 cells in parallel does not detect . Any info on that.

someone can have an answer with this charger. will use again after a while of having it saved and I find the surprise that does not want to charge more than any battery, the problem is not to read the resistances. Have not found bats, there is no Asian bat meter, read the voltage and the cells but not the resistance, this problem or any question?

I tried this method to calibrate my fake charger and it seems to have bricked the unit, when you switch it on now the controls don't work and it instantly runs a discharge cycle on a 1s lipo, I tried to connect a 1s lipo to see if I could cancel and fix the glitch but it just says "overvoltage" and freezes on that screen instead of "connection break"

Very good review,learned to calibrate these things,thanks :D .

Excellent review. Thank you so much. It was really helpful for me.

It's nice to see a proper AVO meter on the bench!

spot on. Simple explanation on how to use a b6 snide charger. Thankyou. (BRAVO)

Thanks for posting this video, I am looking to buy one of these & now i can make sure i get the real product. Thanks :)

I am about to buy one i guess its fingers crossed. Good video i will be using it when i rip mine apart to find out if its fake!

Can you set the desired end-charging voltage for Li-ion as you want, e.g. 4.1V instead of 4.2V ?

Hi Louis I have just bought a genuine B6AC version 2 and am running it together with a PC. I found your explanations very illuminating. The instruction book leaves much unsaid and I would like your insights. I am charging a new 10 cell NiMH battery stack and note that about every 30 seconds the current drops to zero, whilst the voltage stays high. I assume this is a sampling operation of some sort. Do you agree? During a 2 hour charge, this sampling occurred for about 45 minutes, then did not until three samples at about 70 minutes in and finally 12 samples at the end. This looks like normal behaviour but I have seen no comments anywhere Secondly a DVM across the battery during the charging process does not read correctly at all and fluctuates. Using my trusty AVO 8 does give a correct reading. Interesting. Thirdly the whole business of cycling and charge/discharge is not covered well in the book and I am confused. In charge mode there is a More setting to choose cycle count and "R_ PeakCount". Peak count I understand but what is the cycling referred to. A complete discharge and recharge perhaps. Thanks for your time Bruce M
