Simple overview of the LIPO battery (LIPO Explained - mAh, C rating etc)

[@mmatrix00]

First person with the talent to explain concepts in order, using analogies and going from basic to related to applicable. I watched several videos about the topic before this one were they try to make it sound very complicated. Thanks for your simplicity. very useful and please keep them coming. Suggested topics: Use and good battery meter, what makes a better changer, motor / battery combinations, etc.

[@Theamazingskobe]

This has to be one of the best explanations i have watched yet!! awesome job!!

[@BerniiHsler]

Thank you kindly people like yourself are broadening my horizons, when I ask so called know it alls I have so often been led up the gardenpath cause they don't actually know wtf they're talking about . BIG CHEERS FROM ROLY IN AUS!!!!

[@Painless360]

Thanks for the comment. It's always nice to get positive feedback.

[@Painless360]

It's a personal choice to go electric or gas. Electric is quieter and cleaner so for me it allowed me to fly without complaints about noise and exhaust smells whilst I was learning, I wouldn't change to IC now. Happy flying!

[@Painless360]

@thewillage, The 80% rule is about how much you discharge the battery. If you had a 1000mAh pack then you would not want to take out more then 800mAh before recharging, taking more can decrease the life of the battery. If your charger shows the number of mAh going back into the pack as it charges, make sure that it's not needing to put more than 80% back in. If it is, fly/drive the model for a shorter time. Hope this helps.

[@Painless360]

I've added a short video on the main elements of an RC power system to the channel. Thanks for the suggestion! :)

[@Painless360]

Joel, you can. Any charger worth it's salt will stop when it's fully charged so you'll just be topping up any charge that may have been lost. Try not to leave packs fully charged for weeks at a time though. If you are not going to use them, take them down to a storage charge (3.7v per cell), they will last longer that way. Hope this helps.

[@Painless360]

Douglas, thanks for the feedback. It's good to know that the video was useful. I had to figure a lot of this out via questions in forums in my early electric days and some was a little trial and error. Let me know if you need anything else explained. If you are new to electric then my 'Power Systems 101' video may be useful as a very high level intro to the subject. Thanks again.

[@Painless360]

Yes you can but a fully charged pack will keep its charge for weeks and weeks. If you don't use a charged pack, discharge it to 3.7v for storage. I have had packs puff up when I've left them fully charged for months without using them. Hope this help, happy flying!

[@Painless360]

@Gubernator45, the 20Wh is actually redundant here. All you need to know about the pack is already there in the other numbers - Watthours = voltage x ampshours (1800mah x 1.1volts = 20Watthours (Wh)). Basically it's the same as the 1800mah rating and shows how much 'power' is in the pack and how long that power would last. Hope this makes sense..

[@Painless360]

A storage charge is used when you will put the battery away for a number of weeks or months without using it. The storage charge makes sure that the battery never falls below the minimum level (3.5v) while stored away and doesn't involve any unnecessary electrical stress on the cells by storing them fully charged ( I have packs puff up after leaving them over winter fully charged) . I hope this makes sense.

[@Painless360]

@TheBigspecky, I started using the charger that you get with the modelsyou buy but always seemed to be waiting for the charge to finish. I then moved up to an IMAX B6, a copy of a Bantam model charger and found this a great improvement but had problems with the quality of the unit (balance charges didn't work well). I replaced that eventually with a 'real' Bantam BC6-10 charger and have been using that for everything for over 2 years. As with a lot of things - buy cheap, buy twice!

[@Painless360]

That sounds like a great way to treat your pack. You can keep the pack at charge for a week or more but the care you are taking with the LIPOs should result in a much longer life. I've looked at the specs for the Sv2 ESC and the car specs don't list the amperage. Your pack can deliver a huge amount of current so as long as the ESC and motor don't pull more you'll be fine. The rule of thumb I use is have 10% capacity extra from LIPO to ESC, ESC to Motor and you'll be fine. Hope this helps.

[@jetisl77]

Something useful on KZbin what a good idea. Thanks very much for the great guide. i liked the diagrams and examples you gave made things a lot easier to get my head around what it all means. Think i will going Lipo very soon. Thanks again

[@ChiragChaudhari]

This is exactly what I was looking for. +1 for that Water Tank example, makes the concept pretty clear.

[@Painless360]

I'm not familiar with that pack so I had to look it up. If it's the same pack that I found then it's a 9000 MAh pack with a 100C rating and a 7.4v output. Hope this helps.

[@BrothrBob]

Your video very helpfull when I place an order for my first Li-Po battery. I liked it when you broke down the numbers. That was important to me.

[@hectorn.6137]

I've already been using lipos with tb6b charger for about a year now. But I would've rather have seen this video then the many I watched before. Clean, concise, no bs. 👍

[@Painless360]

The amps used to charge the pack to a storage voltage should always be less one 'C'. i.e. in your case use 2.2amps to charge the pack and stop charging when the pack is at 3.8v. That's a nice voltage to store them at. Once you are ready to fly with them again, charge the pack using 2.2amps or less until each cell of the pack is at the 4.2v maximum. The entire pack will then read 12.6v - full charge for a 3s LIPO. Then you are ready to fly.

[@Painless360]

The latest generation of batteries are now allowing for faster recharging. Until now charging at 1c (i.e 2.1amps for a 2100mAh pack) was normal. With these new packs you can charge at 5 times the rated capacity i.e. 10.5 amps for a 2100mAh pack! Great is your charger can deliver that much power as the recharge time will be a fraction of what it would be at 1c as the energy gets into the pack that much faster. Hope this makes sense.

[@Douglas-ic7tk]

Good one dude. You gave out a lot of good info now just starting out on these LIPOs. I've heard about the 80% rule and am trying to locate that information. Great job though, and I've watched just about all of these tutorials. That's a good rule of thumb on that charge rate though. Good work, I'm impressed.

[@billsavage8022]

Awsome video, thanks! Trying to learn everything I can about these b4 even trying to charge mine.

[@tuskegee87]

I very much appreciate this run down on lipo batteries. You hit every point that I had a question on especially charging. that's how I realized why two of my batteries were bad. Thanks again!

[@Painless360]

You're welcome - glad it helped! :D

[@dcilk01]

Excellent video and much needed for newbies like myself.

[@vinnyvdalidemonet8527]

Well Done, Great Teacher. I learned a lot and have confidence and a good understanding now. Great job with explaining the facts and the use of simple to understand visual aids. Thanks for taking the time. I really appreciate you sharing knowledge.

[@donniep90]

Excellent job lad explaining lipos isn't always easy

[@martyisnuts]

@Painless360 Yes thanks mate .I was losing 2/3 of the power but it was -10c and the batteries in this heil are very small and thin. so i would think they would freeze very fast.

[@sosasaney]

Your video was very helpful and most certainly deserved more likes! Thank you!

[@nitheeshkumar7627]

U r c rating explanation is good as compared with other videos good explanation

[@Painless360]

Hi Red, with the latest generation of batteries this 'breaking in' isn't needed. Be gentle with them, charge them at 1c or less and never store them discharged or fully charged and they will last you many flights. Happy flying!

[@unclejack123]

your videos are great newbie electronics videos (which I am).I have lots of model making and flying experience but, little electronic knowledge. you videos are very helpful and not intimidating...... thank you........JRW

[@Painless360]

@SuperMiller1972, thank you. I couldn't find a video that covered what I was being asked by new guys into the electric RC hobby. It's tricky to know what to put in a 101 video, this could have easily been three times longer :D

[@Red5]

Great video. Thanks. I'm curious about the discharge rate of the batteries. I've heard it's good to break in a new battery with several charge/discharge cycles. Should I discharge it @ 1C as well?

[@Painless360]

@martyisnuts, you will see poorer performance from your batteries in the cold. Like all batteries the LIPO relies on a chemical reaction to get the power back out of the pack and the low temperature makes this reaction 'sluggish'. You should keep the battery at room temp unitil you need it and expect to lose about a quarter of the flying time. Hope this helps,.

[@makealready]

Absolutely awesome video. Really taught me a lot and took some of the stress off of me owning a new blade 360QX! thanks so much for the awesome tutorial, keep up the great work!

[@sumanm8741]

Well explained. So far, this is the best video I have watched!!

[@Weemanfaescotland]

👍

[@Painless360]

It depends on how smart the charger is. a little while should be ok but you shouldnt leave a charging LIPO unatended. Hope this helps

[@christopherstevenson9737]

Good details. I like your status tagging system!

[@TheBigspecky]

Hi, very informative video. Cheers. Quick question, any advice on choice of type of battery such as manufacturers? Also, you mention chargers, any advice on choice of charger regarding manufacturers, model etc? Which one should I be investing in?

[@ReasonedRhetoric]

Thanks that taught me a couple of things i never knew. Good Video.

[@Gubernator45]

Great video!! Very informative, but of course I have a question. My Lipo reads Flyzone- 1800mAh - 11.1V. - 20C - 20Wh What does the 20Wh stand for? Thnx

[@gunnsteinnjonsson7449]

This great video was exactly what I was looking for. Thanks for taking the time to explain this.

[@fararable]

Thank you for an understandable explaining, so easy to understand indeed.

[@Bruce1983]

On my GT power x drive 6 charger I had no idea what the number was now I know it's how much charge I'm putting in so now I know once my 4200 mah bat gets to 3360 it's good to go also I haven't been charging my batteries long enough I used to let it read about 3.85 on each cell not knowing 4.20 was the full capacity thanks dude great vid now hopefully I will get longer than 10 mins out of my traxxas bandit VXL :)

[@hateeternalmaver]

hi there, first of all thank you very very much for doing this nice explanation. i still have some questions, though: I'm flying a micro CP helicopter and it uses 1S lipos. with it came a wall charger with an LED. the things that bother me are: 1: if the battery gets low the heli's performance also lowers, so that's the sign for me to charge it. Is that practice okay, or is there a good chance of damaging the battery if i keep flying until it actually stops working (the heli)?

[@SpecialzFXRS]

Thank you sir, cant wait to run my new mini revo 1/16 on a lipo! :p

[@RajasubramaniamBalakrishnan]

Very informative. Thanks for sharing.

[@MMMark1994]

Thanks a lot for the tutorial but still got a question: I just bought a pair of 2s 9000xl lipos from maxamps for my rc truck, but the question is that i am not sure what 9000 XL is compared to Mah, is it the same or some different rating but is equivalent. Thanks again

[@DesertJeff]

Watched for remedial education..... Thanks. Best explanation...

[@cyjo2009]

Very nice informative video! These batteries are Scary Powerful for their small size. Just started using them in projects like super bright LED flashlights.

[@Painless360]

cyjo2009 They sure are, they have one of the highest energy densities. Tons of high current in a very tiny package! You just need to make sure you have a low voltage alarm in the flashlight as they hate to be discharged below 3.5v per cell. Happy flying!

[@bobuk5722]

Thanks Lee. Just started with HT206 Charger/discharger. Have set charge current as you advise. BobUk

[@pauloreyfigueiredo]

loved the analogy with water tank

[@Painless360]

+Paulo Figueiredo thank you, it's the only way I can think to describe it. :-)

[@BigSips]

Thank you for posting this super informative and really helpfull

[@fklotaloi]

Excellent description!!

[@Painless360]

Storing your battery for along time with a full charge isn't good. Also, storing a battery with the minumum 3.5v can cause problems as the pack will slowly discharge when it's stored and take it below the minumum voltage. The answer is a storage charge, This is usually about 3.8v per cell and lets you put a pack into storage and avoid the pack discharging below 3.5v per cell and without the stress on the pack from having to hold a full charge for a period of time. Hope this helps,

[@brushlessmicrot]

IF I am using a 50C 5000 MAH on a Castle Sv2 ESC (Ground esc) its a 1/10 sacvle ESC for cars and trucks will if puff if I am charging at 1c and balance it one every week and if I know that I am not gonna use the pack for atleast 2 days I take it down or up to storage voltage? IMO thats pretty good care for a LiPo but you know more than me

[@zulven]

Very good video , thanks for your time !!

[@Gaspargomezing89]

very god.. showing the ways by te letter...keep it up.. tumbs up!!

[@Racer18crf]

battery came out of the tray and scraped the ground the metal plates protected the cells is this battery still safe to use? (I put back into the tray with electrical tape and tape over the tray and it seem to work fine no smoke came out so the cell wasn't punctured and I would like to know if this is still safe or if I need a new one?)

[@Painless360]

Packs can puff out for many reasons- from pulling too many amps or not being cared for. I had two new LIPO packs puff up over winter when I stored them on a full charge accidently. The C rating on a pack is for a sustained discharge rate, You can pull more amps for a short period of time without damaging the packs.this 'burst rate' is sometimes printed on the pack and for very short period shouldn't damage the pack. If a pack puffs after being used within the C ratings then I'd get a refund.

[@hateeternalmaver]

and 2: During charging, the LED on the wall-charger is red and it turns green when it's done. Is there a chance to damage the battery or even risk a fire when it stays connected some more time even with the green LED on? Thanks in advance and all the best to you man. ;)

[@thewillage]

Can you please explain the 80% rule there. Do you mean that when you charge a battery you need to set you charger up so that it will only charge at a rate of 80% its capacity? I'm confused.

[@doctor567]

Thank you so much. Great explanation.

[@rabeiro]

perfectly explained. thank you for taking the time.

[@martyisnuts]

how does Cold effect battery just bought blade 120sr heli and when i took it out in the cold i only got 2 minutes flight time .Would you know anything about this? thanks

[@650hpreventon]

so i have a 3000kv motor, 30A esc, 2200mah 3s 30C battery. i notice even without a prop(6x4 is i will use), it still get hot on the shaft. i dont know why, the battery C rating is too high, or the esc should be 20-25 amp. thanks

[@DOTdirtbiker]

what is the difference between storage charge and fully charged?

[@scottharrell4616]

This was a great video, thank you so much. I am brand new to RC flying and trying to commit all this to memory. I do have a question that I think I Understand but I want to ask to make sure. If I buy another lipo battery and I increase the MAH from 1500 (what the quad came with) to 2200 I would not be doing anything wrong to my quad? If I am understanding correctly than I would just be increasing the storage tank by buying the 2200 MAH battery. To me this would mean that I would increase flight time, correct? The 1500 MAH can be charged at 1.5 amps where the 2200 can be charged at 2.2 amps correct? Thanks for your help, I'm gonna go watch your video again.

[@Painless360]

+Scott Harrell so long as the battery pack has the same voltage (3s, 4s etc) then it will not hurt anything. Remember that the extra weight will affect flight performance. Best of luck!

[@Elkins82ify]

Scott Harrell that was the exact question I had and looked to this vid for a possible answer. Thanks! Happy flying

Great Video, I want to build a 500mm quadcopter, with 2216 820kv and 40a ESC, what battery would you recommend that delivers the longest flight time?? Or should I go for stronger motors to get a 5500mah battery? love your channel

[@Painless360]

+Francisco Antonio Font Diaz Larger batteries weight more so you need to figure out the maximum weight the quad can carry and pick the largest pack it can handle. Have a look at the max thrust for those motors and work back from there. Best of luck.

[@frankfont08]

Thanks for the quick response

[@jjab99]

An old video, but a very good one. Many thanks for this, it really helps me out as I am brand new to RC world (don't actually get any RC until my birthday at the end of October) and need all the help and information I can get. Do you think this video could be remade and updated to take account of anything new in batteries and charging??? Have a great day, Joe

[@Painless360]

Everything in this video is still relevant. See my introduction to remote control playlist and more basics.. best of luck!

[@AdamShelton61]

Hi, great video! What would you recommend as a storage charge as a general rule?

[@Painless360]

+Adam Shelton 3.8v per cell is ideal. Happy flying!

[@SirArghPirate]

[@Marksmonkey1980]

Great video. Thanks

[@NinjaKiwi2500]

Thanks this video helped a lot! Also how many amps should I charge my 4000mAh battery at?

[@Painless360]

ninjakiwi2500 hi, unless there is something else written on the pack itself, or in or any accompanying literature, then assume a 1c charge. I.e 4amps. Hope this helps. Happy flying.

[@NinjaKiwi2500]

Painless360 Thanks for helping, and yeah it says 4A on the pack so I'm going to do that.

[@basvanderknaap]

From the image at 8:15 i understand that the voltage should drop no more than 20/30%. Does that also mean you can only use 20/30% from you mAh.

[@Painless360]

+bas van der knaap almost. A fully charged pack will be 4.2v per cell. If you pull 80% of the mAh capacity from the pack then you'll have approx 3.5v per cell and a pack that's effectively 'empty '. Best of luck!

[@zigzag1944]

Very good video. Great job. A quick question please. Can I replace a 7.4v 2 cell 1800 mah 25C lipo battery with a 7.4v 2 cell 2700 mah 10C lipo battery to get longer flight time and what are the implications please? Thanks

[@Painless360]

+Zig Zag possibly. The extra weight if the other pack will stop all that extra capacity being used for longer flight. Also the larger pack with only 10C will only be able to provide 27 amps (versus the 45 of the original lipo) so check how much current the model needs.. Best of luck

[@richarwalker]

Painless360, what type of 12 volt batter is best to use to charge LiPos? Should I buy are cheap car battery and a charger for that, or a golf cart battery and charger for that? Well done video mate, Cheers, RAW

[@Painless360]

Do you mean out at the field? I tend to fly from places with AC mains power so i use a dedicated 12v 20a bench power supply to power the LIPO charger. but remember that you need to factor in the current for the charging. i.e to charge a 6s pack at 5amps actually pulls 10amps. Sorry I can't be of more help. Happy flying!

[@Painless360]

elie eid Hi Elie, tricky to answer without more detail but you need to be able to supply a little more than 160amps (4x40A). Weight is a factor as a lot of the model weight ends up in the LIPO pack. I would look at 4000mah packs with a 35c/40c burst spec. Larger packs will weigh more but give slightly longer flight times..

[@elieeid8865]

thank you sir for replying me.the total weight of my drone is about 7pound or 3.17515kg including all. you think 22.2V or less. and i am looking for flight an average of 15 or 20mm..

[@Painless360]

I would look for a 4-6s LIPO pack if you will be that heavy. You will need a LOT of mAh to fly for that length of time and a very low KV/large prop setup to be as efficient as possible. Long flight times with larger models is an art form.. Best of luck with the build.

[@Painless360]

So you need a 3s LIPO (12.4V) or a 4S LIPO (16.8V). The more mAh the longer the flight..

[@kristinemaegallabaldoz269]

if im going to use 5000 mah 4s lipo 25c, is it safe? will it not burn my 40amp esc?

Hey, I want to know if you could switch out Lion battery of 7.4v 1100mah for a Lipo 11.1v 1000mah? higher volt and lower mah is from helicopter. Thanks.

[@Painless360]

Hi Viet, I would replace the Lion battery with a pack with a similar voltage. i.e. a 2s LIPO pack that will give out 8.4v fully charged and be at 7v when depleted. Similar to the LIon pack you alreadey use. You don't mention what you are putting the pack into but usually going from 7.4v to 11.1v on kit that can't handle it will cause a problem. If you are looking for longer run-times on the model then look at a 1800-2000mah 2S lipo pack and search to find the smallest one that will deliver the power you need. Hope this helps.

[@Kevinfromsale]

Thank You! and I subscribed.

[@youngxcontrakidyoungxconta8581]

if the lipo battery is puffy will it still function normal if still work or will it loose power fast?
