I can definitely validate this! I bought two Auline 4s Lion packs for my Dji goggles to run on. I been charging them on 1.5/2.amps Lipo settings at 4.2v and it has reduced there life significantly. Versus two other 4s Samsung 18650 packs i built at the same time I bought the Auline packs.I been charging the Samsung 4s packs on strictly on Lion 4.1v .And now the Samsung packs out performed the Auline packs. So it definitely reduces the packs life span. Good video Bruce!

I've just started using Li-Ion packs and wondered about all of the conflicting information. Thanks a lot Bruce, for once again clarifying things

[@Ra-zor]

Finally, someone else telling people this information about Li-Ion. Been telling people this for years, and for some reason they wont listen and still charge to 4.2v and discharge to 3v and expect 500+ life cycle but will be lucky to hit a hundred - and then complain!, where as a 90% charge and 30% discharge (even 20%) will hit 800+ cycles easily.

[@yash_ar]

When you say 20% discharge do you mean don't let the pack go less than 20% before charging? Or you mean don't charge unless you're down to 20% or less??

[@Ra-zor]

@@yash_ar Don't let the pack go below 20% before charging... Also if possible draw as little current as possible while discharging, and never meet or exceed a packs rated discharge current.

@@Ra-zor let me ask you something else, do you know if I can swap out a 3.7v Lipo for a 3.7 Li-on in a LED flashlight and expect the flashlight's built-in charger to charge the new Li-on without issue or is this not going to work?

[@Ra-zor]

@@yash_ar If the fully charge end voltage of the new Li-Ion is the same as the old Lipo (usually 4.2v but double check how your torch works), and the new Li-Ion capacity rating is equal to or greater than the old Lipo (C rating), then there should in theory be no problem (but always monitor the first few charge cycle anyway for heat etc...). You need the new cell to have the same charged cut off voltage as the old cell, and same discharge voltage (or lower) and be able to handle the same bulk charge current as the old cell. Also the battery monitor in the torch will probably be a bit off as it will be calibrated to Lipo, with the meter showing a possible slower or more rapid drop off at the upper / lower end of the discharge cycle... Of course everyone modifies anything at their own risk 🙂...

Extremely informative. Was just charging my my traxxas 3c lipo, and I noted that pack bloated a slight amount. I quickly disconnected it and made a salt water bath for it. It was a used battery given to me, so I don't know it's history. I went to the local hobby shop and even the attendant there said how much he hates lipo batteries. I agreed as I have a nimh pack I purchased in 2012 that I still can use today. I maintained it properly, and my cc02 with its sport tuned motor gives me about 1h45m dive time consistently. I asked the dude if he sold li-on batteries. He said no, and didn't know if they made them for rc or not. I may go and look for some. My aged onyx 5000mah 7.2 nimh pack is showing its age slightly, and now I am down a traxxas pack. So I may be doing some battery hunting.

[@olafschermann1592]

Charging to 4.1V extends longterm life significantly. Thinkpad notebooks have a software where you can limit the charge. I set it to 80% max. and after 8 years still had 2h runtime. Regular users have 50% runtime after 2 years.

[@FlyingFun.]

Spot on, import addition is storing fully charged is very bad for battery so store at 50% and charge just before use is best,requires some planning and not always practical but most damage is done to a cell whilst sitting fully charged for long periods.

[@loc4725]

So charging (not discharging!) LiPo's on the Lion setting is a good idea for cell / pack longevity?

[@JimBoomer]

Absolutely! It just depends on your use again. I mostly charge my FPV batteries to 4.2v just because the super short flight times but a lot of my RC car batteries I usually only charge to 4.1v since RC cars last so long on a charge.

[@loc4725]

@@JimBoomer Excellent, thanks! I was a bit concerned because LiPo's have a specific charge cycle but if it's the same just with different terminal voltages then I'll give it a go.

[@1Hippo]

Yes, all Lithium batteries use the simple CC-CV charging method, so it is basically just a power supply with current and voltage limits (and BMS/balancer for multi cell). Most chargers allow to set the current and realize the voltage limit in these LiXX profiles, but on some you can also configure custom voltage limits, that is the only differences between profiles. PB is similar, only NiMH charging is completely different (delta peak detection). A downside with lower voltage limits is that it takes more time, even though it puts less energy in. Depending on the internal cell resistance it will spend much more time in the CV phase and low current. That is why like to use 4.2V instead, but stop charging early, then the cell voltage drops down to about 4.1V after a few seconds. Still charge it fully from time to time and let the balancer do it's job to make the cells equal. This trick is often used in modern consumer electronics, the battery controller monitors the pack capacity and stops the charging already when the expected capacity is reached, to skip the lengthy CV phase for the last few percent and improve longevity at least a bit with lower idle voltages. They go up to 4.4V while charging though, which wipes out all longevity improvements there...

just found this vid because I wanted to know what ppl charger their "modern" liIons at. I often set 4.18 as endVolts - since those last 0.02v seem to take forever on the VTC6 at least. I have a huge list of 6S packs for 7" longrange drones now - and I noticed that LiPoHV have a pretty decent WH to weight ratio - close to the LiIon ones! Do you have experience with HV lipos? Is the overcharging to 4.35 very bad for those cells (even if they are made for this - it's probbably just a marketing thing and they will wear out sooner than normal Lipos?) thanks greets, Mario

[@ConstantineCraft]

Good to know! Thank you for educating me!

[@alphacharliekilo5976]

When you measure internal resistance what values should cause concern? Values are typically much higher than lipo even when new.

[@RCModelReviews]

If my Li-Ion cells start to get above 22mOhm then I consider them to be getting tired. Of course when measured on *my* charger -- different brand chargers can produce wildly different figures for internal resistance because it's a figure that depends very much on the state of charge and the current being used to measure that IR.

[@franciswong26]

@@RCModelReviews Hello! This is a great video! Regarding to the internal resistance, I found the value is different when in charging and not in charging. So which one should we take care of? And at which value, for LiPo and Lion, should we need to consider replacing them? Thank you!

Awesome info Bruce and LiPo/Lilo/LiFe safety should always be #1!! People if you've ever seen a fully charged 6S 5500 Mah battery go up....It's frightening......! ***EDIT*** Most of my Li-Ion packs are protected by a small circuit on the battery itself (So they are slightly longer) so it doesn't really include me as I have an extra level of protection built in with mine. I've always used the appropriate settings as I didn't know, the chemistry had changed slightly with Lithium-Ion batteries (18650's etc) Never really do long range stuff... too scared I'll lose a model lol. I use them in near everything... torches/work lights.. cheap chinaquads (Great conversion!!!), battery banks. I did learn something today though...lol. Check the batteries data sheet.!

[@P-Bee]

Many modern chargers let you tweak the desired end voltage for each battery type. So for example on my ISDT charger I can set my LiPo batteries to charge to a maximum of 4.15V. I always do that when charging the night before flying because the less time spent at 100% the better. It only makes a difference of a few seconds of flight time but the batteries will likely have a much better lifespan. My best batteries are LiHV (4.35V per cell) that I have never charged above about 4.20V. They are 4 years old seem like new.

[@erpringle]

So if I charge my li ion 48v battery pack with a 5 amp lipo charger and make sure I only go to 90% charge would it be safe ?

[@needmoreboost6369]

Off this topic slightly but a few years ago I had a cheap 4 port 6a turnigy charger and towards the end of it’s life it started charging lipo’s to 4.4.3-4.4v and at first I took advantage, as I was mostly doing speed run’s! but unfortunately the cheaper batteries like red backs and zippys didn’t last long! but a futaba align battery and some Traxxas batteries are still tight after many years.

[@ronniepirtlejr2606]

I've been vaping for over 5 years now. I use only the 18650 batteries. I found out that if you want your battery/s to have a long life? Charge them at 4.2 Volt 500 milliamp. Constant current, constant voltage. Let them cool off first before charging. Can you charge them faster? Sure you can, At the cost of the batteries lifespan! If you don't like waiting for the slower charge of 4 hrs. BUY MORE BATTERIES! You can learn a lot at the Battery University website!👍🇺🇸

[@PatrickVannie]

Would like your opinion on how to look at a pack made out of Samsung 21700 - 40T cells. If i would make a 2S3P battery pack then i would have a pack with a charged voltage of 8.4V and a capacity of 12.000Mah. My question is how to look at this when i would use this in a model airplane where the motor draws peak amps of 100A. Can you divide the 100A by 6 cells so that each cell has a max amp loading of 17A ? Or would the max amp loading be divided by a factor 2 because it is a 2S pack, this would give a max amp loading of 50A per cell ?

[@flat-earther]

I think you devide the amp draw of your motor by the number of batteries in parallel. So in your example you have 2S3P, so 3P means that if you motor draws 100A you divide 100 by 3 which is about 33A, that is how many amps is drawn from every individual cell in your 2S3P pack.

[@Vousie]

Yup. And yet, my lipo charger's liion setting by default cuts off at 4.1v. But that's only the default. Like on RCModelReviews' charger, mine also has the option to change the cut off voltage.

[@100SteveB]

One question Bruce, what do you recommend when it comes to storing them? Obviously we know that lipo's like to be stored at around 3.8v per cell, is that the same for Li-Ion? I can't find much information on the subject, so to play it safe i leave them at 3.85v per cell.

[@RCModelReviews]

Yes, like all lithium chemistry batteries, they'll last longer of stored at their "nominal" voltage which is anywhere from 3.6V to 3.9V. If you're storing for just a few weeks then 3.6V is good, if you're storing for many month then a slightly higher voltage would be better to account for a degree of self-discharge during that period.

[@AEROERGO]

Very useful video Bruce!, i wonder if you can explain how to recycle them from laptops battery packs, i have few of them and very ofter they just have one bad cell and the rest are ok for make a pack like yours. Thanks!!

[@Meonlymeagain]

I have got 100 or so cells for used laptop batteries and yes get about 75% that can be used again but many of the cells have specs that indicate discharge rates less than 5amps max. I do not think you would get much life out of recycled laptop cells if used as high amp draw applications. It could potentially cause battery failure with bad consequences.

[@RCModelReviews]

as chico7000 says, laptop batteries tend to be low-current types and some of the older ones may even be 4.1V cells. They're fine for using in transmitters or as a pack for your FPV goggles but I wouldn't use them for a flight pack.

[@listerdave1240]

@7:55 It's not that lithium-ion lasts longer than lithium-polymer but the form they are packaged. What you are comparing is pouch cells vs cylinder cells. Even with the exact same chemistry cylindrical cells will generally last much longer. The reason is that most pouch-type cells suffer from delamination long before degrading chemically as there is nothing substantial to keep the layers in good contact with each other. Any gas that is generated collects in pockets between the layers pushing them apart thus reducing the active surface, reducing capacity and increasing internal resistance. With cylindrical cells this cannot happen except in extreme overheating situations. The metal cylindrical shell is strong enough to prevent the layers from being pushed apart causing the excess gas to find its way out of the cell rather than pushing the layers apart. The disadvantage of cylindrical cells is of course that they are considerably heavier for a given capacity and will usually have a lower C rating due both to their much smaller outer surface area as well as higher internal resistance due to having one long continuous set of plates rather than many layers paralleled. (The latter issue has been solved recently by Tesla but AFAIK no one else is using that solution)

[@fishbonez5670]

If you need to discharge a LION to a storage charge, is it the same as a lipo 3.8?

[@radzgardiner8108]

Bruce, i have a few questions. I've crashed quite a few lipo batteries with in my planes over the years, some made it some didn't, and those that did shortened their life span. How do li-ion batteries compare? Since chemically they are different as well as internally, and the casing is harder compared to the softer lipo shell? since these batteries don't puff up or look like a banana peel after been driven into the ground at high speed.

[@RCModelReviews]

The metal case of the 18650 cells does offer better resistance to physical damage but it's still a good idea to give any crashed pack a good visual inspection before storing it or using it again.

[@MartinVenter371]

Very nice video!

[@Magneticitist]

I believe the real world effects can be seen from a marketing and profit standpoint these days. I often see various cheap RC stuff sold where the charger requires a special CC limited unit that plugs into USB, but the other end is a standard plug so many people out there could likely get confused and bypass the special charger altogether. This would result in small cells being charged very quickly, likely at least 1A but probably more.. and this duration would not be long because the cell would become fully charged quickly and begin to draw the lower current levels in a short period of time. This has apparently been safe enough in the consumer world to not cause safety issues, and beneficial enough in the corporate world where it requires people buy more batteries faster.

My original TG 4s-1300-65c packs have over 1200 cycles in my Raptor 5" quad (peaks 120amps) and i fly for 90 sec and they end up around 3.85v, perfect for storage. Those packs still work great for planes and now have 2100 cycles on them, they are now 4 years old. Treat them well or buy more, your choice. And regarding Li-Ion charging to 4.2v, monitor the cells closely first cycle, if they get warm, they are not happy.
