Testing 18650 Li-ion Batteries from Old Laptops with my Imax B6 charger

[@avid0g]

Please note that when he refers to four digit numbers and says "Amps", the correct term is "milli Ampere hours" abbreviated mAh. This is the cell capacity.

[@freeenergy]

After fully charge the 18650 battery you have to leave it about 10 days to be sure they don't lose voltage.... And after that you discharge it to make capacity..

[@guily6669]

Yeah I agree waiting a bit of time to actually test them, I have a few 18650 that seem normal until we wait a few time and see that they are kaput, they keep self discharging like nuts so it's a battery to be charged and used right away only since after just 2 days it already lost quite a bit of voltage which makes it a very terrible energy storage source...

[@exgenica]

One of the first tests to run is the cell's internal resistance. You can do that immediately and it will tell you a lot about the health of the cell. You want cells with as low internal resistance as possible. Also see videos/blogs about "matching lithium cells" or "matching lithium batteries" and similar.

Sir you have done an outstanding job. I congratulate the...Im just waiting for my b6....hoping Canada Post does not go on strike. Once again it is great that we can all hear you loud and clear, and best of all in English..the universal language.

[@exgenica]

It's also a good idea to try to use cells with internal cell resistances that are close as possible. E.G. don't pair a cell with 63mohm internal resistance with a cell that has 300mohm internal resistance. The lower the internal resistance the better.

[@ponkuna]

I bought an IMAX B6 and keeping without knowing how to begin with this stupid manual which is useless for a beginner. Thanks today I charged , discharged and recharged my battery first time successfully with your very basic coaching video. Thanks a lot on behalf of all beginners.

[@phinok.m.628]

Well yeah, that's sort of the way to do it... You should however probably leave them sitting for a couple of days and measure the voltage to see if they self discharge, since a battery that is empty after a week without you using it isn't necessarily particularly useful, not to mention Li-ion batteries can get quite dangerous in many situations including when they are internally shorted obviously.

[@francopieruccinifaria9454]

Why the first time it was drained was 1676mAh and the second time 2555mAh taking into consideration that in both cases the battery was completely full? Tks

[@dennisnilsson5430]

It's probably cause it's been sitting a while at under voltage... needs a couple of charge/discharge to work properly again.

[@ponkuna]

IMAX B6 manual says it will take 10 discharge and charge process to get the full capacity of the battery. That's mean repeat discharge and charge will increase the capacity that's what you got.

[@garrygemmell5676]

Great explanation of how to use the imax B6. Cheers dude!

[@exgenica]

This is for people who are just starting to check and recharge old lithium cells (this is an old video). I STRONGLY RECOMMEND GETTING AND USING THE THERMAL SENSOR for the B6 balancer/charger (or whatever unit you're going to use for this purpose). This can help prevent the "they can get hot and uh explode and cause issues" part of the testing and rejuvenation procedure. You can use velcro strip to affix the sensor to a cell you're charging and it will sound an alarm and stop charging at a temperature you select ahead of time. For example, if you set it for 150F then it will shut things down when the battery surface reaches about 150F. This will help prevent outgassing/venting, thermal runaway, and fires and "uh exploding". The sensor costs anywhere from about US$2.40 to US$6 and may ship for free depending on different factors. That is really CHEAP INSURANCE and well worth the few bucks it costs.

[@clivewhitworth4755]

[@malovanyy]

Can someone explain why the displayed capacity is so far off from what you get by multiplying current by the discharge time? At 3:41 the results of the discharge shows that the capacity is 1676 mAh and the discharge time is 335 min. Shouldn't the capacity be 335/60*500=2792 mAh (discharge current was set at 0.5 A) ? Or does the charger use some pulse mode of discharging so the discharge current is actually lower? Or does the charger recalculates the capacity to the rated voltage of 3.7V?

[@smuglor]

THX for writing down the question. I am very interested in the answer, too! Besides I wonder why the the two capacity tests vary so much and why discharging at more Amps ends in more capacity?!

[@eskisful]

You should look at discharge curves. When cell hits 3.0v the current starts slowly decreasing. Because of that your calculated capacity is wrong

[@BeginnersTech314]

I have been told that the charger calculates the capacity. I have not tested that statement.

[@KitKat-sh3ch]

335/60=5,583 time is in 60parts. Metric is in 100's. That's why

[@oneeyemonster3262]

K....but how can you figure the C ratings. I ask becuase I want to use it R/C stuff. That's the different in me installing these batteries in a floater that will just cruiser around or a speed demon Wrong C rating in a speed demon might cause an explosion...just saying.

Hi there. FYI, milliamperes/hour means that you discharge the cell at 1 amp will return a realistic value in milli ampere hour. Discharging at 0.5 amps you would have to divide your results by two.

I have several SLA 12 volt batteries of varies current ratings. I want to sort out good from bad. What would be the procedure to confirm the current capabilities using a imax B6. I just picked up a B6 mini. These a are Lead Acid 12 volt batteries used in Computer UPS back ups. The discharge current can't be set any higher than .5 amps due to the 5 watt max power rating of the imax. At lower voltage batteries I can get more current but higher the voltage the less discharge current is available P=IxE 5w = I x 12 volt 5/12= max discharge current. Is the method you used exactly the same for 12 volt SLA batteries?

[@ModifywithManoj]

Is the charging rate and discharge rate different for healthy batteries.

[@Bagoly_1]

so 1st u have to charge up to full to 4.10v, then discharge . write that number down . 2nd have to change up full again to 4.10v , then discharge again . and that number is the capacity ? what if first discharge it, then charge to full 4.10v?

[@aspergerhellasbn]

On previous message i was wrong did not noticed you were xharging on li-ion program.But why they have end voltage 4,1 and not 4,2?

[@exgenica]

I know this is old video/comment but to answer... I just setup one of the B6 memory allocations to set up my own parameters. That way I control the upper voltage, the min voltage, charging and discharging currents, etc. It also lets me compensate for inaccurate voltage readings by the B6. For example, to charge a Li-ion to actual 4.20V I set a memory slot to charge to 4.23V. I know it's not a lot, but it lets me also compensate for new version li-ion/LiPo cell parameters like discharging to 2.7V instead of 3.1V to which the B6AC V2 defaults.

[@sreekumarUSA]

Thank you for taking time to explain how to determine the capacity of 18650 Battery. But, you confused me towards the last stages of your explanation. Your procedure was .. 1) Charge the Battery to 4.2V 2) Discharge the battery to 3.0V 3) Charge the battery back to 4.2 and determine the final reading of Battery amps. This was what i came to understand. Am I right? Please respond. Thanks and regards.

[@BeginnersTech314]

the charger displays the amount of amp hours it put into and takes out of the battery. so if you charge it the whole way and then discharge it to a safe low and is says it discharged 1000mah and then you charge it back up and it puts roughly 1000 back in then you have a 1000mah battery. it is not 100% accurate but it should get you close to it. now that being said there are chargers out there for $20 that automatically test the 18650 battery and tells you what the amp hours are without you having to do anything.

[@HDXFH]

Gotta love 18650s, handy as!!!

[@ademline2010]

the capacity of the battery you last measured was 2555. You have typed 1676 on the paper. which?

[@avid0g]

1676 mAh vs 2555 mAh from the same old cell is an indication that the capacity improved after full cycle charge/discharge twice. This happens because the cell was discharged too far in the laptop battery and left in an excessively discharged state for a long time. The slow charge and discharge (twice) improved the fractal pattern of molecules on the plates. When cells are excessively low in voltage, it is best to charge at unusually low currents to improve the cell capacity.

So I am not sure if i completely understand your set up but my guess is the charger is only pushing 5 amps to the battery and so it will only draw 5 amps from your 30 amp transformer. So you cant charge your batter at 30 amps with that charger.

I deeply tested this charger with a 18650 and it does not perform very well: At 0.3-0.5A charge rate it can only charge up to 1100Mah (it's an older battery), I verified backward using discharge method too. I have a simple LiOn charger TP4056 module and the same battery it can charge up to 1500Mah. Again, I verified it by discharge. I measured everything twice.

[@PolakeXD]

1:46 I see that your charger displays 3.6v at Liio charging mode but I think that that's wrong :P At my original SkyRC iMax b6ac (second gen) charger I set up the LiPo charging mode and with this charging mode I can charge my Lithium Ion cells to 4,2v. Until now I never got any problem with my harvested 18650 batteries Only the discharge process was done on the proper mode since I didn't want to turn any of the 18650's into some small flying rockets : P Btw. You have there a clone of the b6. The original iMax/SkyRC chargers doesn't have any EC or FC labels and they never would have this trash can since this product doesn't contain any batteries inside

[@chrissybabe8568]

You have made a mistake with your charging. LiPo and Lithium Ion ARE NOT the same. LiIo cells are 3.6v and LiPo are 3.7v. You should not use the functions for one of these to charge the other as they have different end voltages at both ends. You must use what is written on the battery to decide what cells you have. If you think the voltage is incorrect (because dishonest people sometimes resleeve the battery and they may have made a mistake) there are subtle ways of deciding which is which.

[@JoseGarcia-px9xj]

so for checking one single cells it would take a lot of time, maybe 6hours what would you do for check 1000 cells

[@avid0g]

Jose, nobody replied to you for a _year!_ series solution: Put several cells in series, but connect a _cell balancer_ to the cell/battery holder. Use a charger or dc/dc converter with both current limiting and voltage regulation. Set the charging voltage to [number_of_cells] * 4.1 Volts. Set the current limit to 0.5 Amps (or 500 mA). Make sure the balancer can handle the charging current that you set! You may also connect many cells in parallel, however, the current may not flow through all cells equally which will put more thermal load on some. One purpose of testing the cells is to determine this property! Also, it is very dangerous to put cells in parallel if their voltages are different. Very High currents may occur, causing some cells to charge far faster than their capacity. You may use some resistor or light bulb to limit current while adding another cell (in parallel) to the battery pack, but be sure to measure the initial current, and insure that the current level is safe.

I know this is an old video/comment but to answer... There is a "System" setting in the B6 that let's you turn balancing on or off as desired. It comes in very handy when you're charging 2s1p packs that don't include a balance output. Of course, over time...charging mismatched cells without balancing can lead to fires or cell damage (that didn't result in a fire).

[@exgenica]

Also...keep in mind that the B6 manual says NOT to use the B6 to charge battery packs that have internal protection circuits...or at least my B6AC V2 stipulates that limitation...and some of the cells or packs you run into may have protection circuitry.

This charger is not much good for best measure to nowaday Li-ions since their capacity nowadays according to the datasheet discharges to a way lower voltage and charge to 4.2 Instead of 4.1 unless you use LIPO setting which charge to 4.2v but the discharge rate doesn't go as low as the datasheet of most current LI-on. Though if we really want max cycles out of LI-Ion the IMax is the right charger since the more voltage they are charged and the lower voltage they are discharged the lower will be their life cycles... Though I heard there is a CFW for this IMAX but I think we need to solder a new connector on it...

[@tehdreamer]

My Imax b6 discharges li-ions down to 2.5v and charges to 4.2v. I guess it depends on the version.

This is not a genuine Sky RC charger,there are several videos that show this charger to be unreliable and inaccurate. Any comments.

I can help you, just open the rechargeable li-on mode to dùm I do not know how to open up ..lam Thank you help me .cam more

[@JoseGarcia-px9xj]

your charge to 4.1V and discharge to 3.0V this should be a difference of 1.1V, so if you have a 2200mA/h 18650 this mean you are using only 2.42WH of the total capacity of 9.24WH, I'm right or I'm missing something

[@williamwidener4282]

Jose Garcia a better test would be using a mah meter and a load with thermal cam app for watching the battery. Jehu Garcia does this in one of his videos using a power inverter as a load. There are load testers in to $150 range to perform the same job but a bit more accurate and even loading

We r using Samsung 18650 3s battery but we r unable to fly our drone

[@BeginnersTech314]

Well First off what type of drone do you have?

[@khemrajdeulkar9803]

Beginner's Tech Quadcopter with 1000kv bldc motor and 750 frame

[@rickyfoster7912]

Khemraj Deulkar if the cells are from a laptop battery the discharge rating might not be enough some 18650s are 1c and some are more 15c and higher. Try using a 12v lithium drill batter ect on it if they work it's because the drill batteries have a higher discharge rating

[@BeginnersTech314]

yeah if you are trying to use laptop batteries I doubt they will work

[@exallievididonbosconcrgrou7544]

You've got a fake IMAX B6 charger...that's why you were getting DISCHARGE and CHARGE readings for the same battery NOT MATCHING. Your results are misleading you and will mislead you on the projects you have in mind. Look over again your unit and figure out why it is fake. Look for a serial number at the back which you can check on the web with the manufacturer. Good luck.

[@wesleystaley5501]

Dam I paid more than that...does that mean they do not work

[@chompchompnomnom4256]

460 minutes is 7.66 hours. So 2550mA / 7.66h = 333mAh. That's the capacity of the battery

[@BeginnersTech314]

from talking to other guy's the charger should do all that math and mAh of the battery is supposed to be what the display showes. and thses batteries have more than 330 mAh of charge.

[@chompchompnomnom4256]

It seems to be counting up slowly from the beginning and over the full 460 minutes rather than working it out at the end

[@BeginnersTech314]

***** i have been just doing what everyone has been telling me. and the other thing is as it gets closer to the end the charge amps drops. so that would mean for the last 20 min or so it is charging slower so would that make your calculation off buy a little?

[@chompchompnomnom4256]

I just bought one for myself so when I get it I will try it out. Can you tell me what voltages the LiPo setting can be set at? I would like to be able to charge my 24V ebike which would be a bonus.

1 = A cell. More than one cell = A battery (as in 'A battery of cells'). It is technically not possible to have a single celled battery!

have my clone for 3 yrs with it working perfectly. my vom agree's with the chargers displayed voltage reading.

[@daand12]

1. Use LIPO mode 2. Get a real SkyRC charger and not that piece of junk.

[@BeginnersTech314]

1. these batteries are not lipo batteries they are lion. 2. this charger works great so i dont need another one. 3. please subscribe :)

[@daand12]

Use lipo me to charge them to 4.20v. That's what they are designed for. A real skyrc charger does charge them to 4.19v and not 4.22v what this one does.

[@georgegibson707]

The manual says LIPO is 4.2v max and LiIon is 4.1v max. I would definitely use the LiIon 4.1v because that's what the 18650 are, and everyone says a slightly lower charging voltage will greatly increase the life of the cell.

[@gixxerboy555]

it doesn't make a big difference in lifetime

[@dabugguy958]

IT IS COUNTERFEIT! 1.) The genuine SKYRC iMAX B6 has GOLD plated output jacks for the 4mm banana plugs. 2.) It has a SKYRC logo printed on the upper right corner. 3.) A scratch off holographic sticker reveals a code that you can verify unit through SKYRC. 4.) The CE (for China Export), FCC & Don't Recycle tags are located on back of unit, not front lower right corner. 5.) The screws holding the body together are black not chrome plated. 6.) The counterfeit box doesn't even come close to looking like SKYRC's box (It's not black & doesn't have diagonal red slashes.) 7.) There are a whole slew of internal dissimilarities, too many to type, one though, gives false readings on the display screen which could be dangerous!! I hope I covered enough external dissimilarities to help you weed out the counterfeit chargers from the genuine item. Spending the extra money for the real deal may make the difference between "Home Sweet Home" and a FIRE GUTTED HOUSE!! It's YOUR choice to save a couple of bucks........Read more Show less
