Scabbage what is this
New to RC. You guys bring alot of great knowledge for me. Keep em coming!!
Thanks flight test....i learned the hard way about LiPo safety last summer when i left my lipo charging in the back of my car and went inside the house , half hr latter i was helping the fire department put out my car lost it and all my planes and tx!
Wow that sucks, hope by now you have more planes than you did 6 years ago
R.I.P lesson learned
I've not got to the end of the video yet, but the section on charging and balanced charging has pretty much answered 4 of the questions I've had for quite a while.
Great video, I mean it ...! I was always the old school hobbyist believing EPO and batteries had no place with in this hobby and to use it was sacrileges at best.. But I guess the world is changing and so must I....! So thanks for teaching an old dog a new trick...!
Great tutorial guys. Just one other thing that could have been mentioned would have been an explanation of storage charge. If you know you're not going to use your battery for an extended period never leave it in a fully charged or discharged state but instead use your charger to take it up/down to a safe storage charge level. Regards = Nidge
This is the exact information I'm looking for.
As an old bloke trying to get into rc flying this is an invaluable resource, Thank you.
This video is making me a bit paranoid now, I can't stop thinking that my lipos are going to kill me!
Thanks for the time You took explaining proper use of batteries. I am new to lipo ‘s and the info was much needed and explained in a way even a slow learner such as myself am now more confident charging and discharging lipos. I very much enjoy Your other informative videos. Keep up the good work and God Bless.
Once you guys are finished with the 10 part series it would be great to get it all on a DVD or as a download, my friends ask me all the time about getting into the hobby and I think these videos all together would be a good start for them.
How do they not have UA-cam..?
I refer a lot of people who are trying to get into the hobby to your beginner series. Great work guys!
Good explanation on the C rating and what it means. People are often so confused with that.
You guys forgot an important thing... There is an optimal amount of charge for storage with LiPo batteries...
Optamizm
Ikr?
What is it?
3.85 V per Cell
Which is better for RC :Li-ion or LiPo battery?
This is the EXACT type of video I have been looking for being new to flying FPV Rc's. Thanks a lot.
Thank you guys for this, I have it saved and always come back to it and this series.
You guys are brilliant.I am going to hunt out all your other beginner series episodes.
I am a newbie and have acquired three Lipo chargers in the last few weeks yet I had no idea how dangerous these Lipos can be.
Newbie here says massive thanks! So much learned in 20 mins.
this is a really good series. accessible yet diligent. the pro is very earnest and it makes you want to learn!
I didn't know I was abusing my batteries thank you for this video, very helpful !!!
More on picking/using a computerized charger would be *greatly* appreciated! And power supplies too of course!
6 years later and this video is still useful and relevant. For me at least. Though probably wouldn't hurt to check if there is any new or updated safety tips to add. Could be a good throwback vid for you guys. Most battery charging videos I seem to keep finding are 4-9 years old.
Great video sounds like a sand bucket in the hanger is a good idea!
Nice work guys, pretty much everything covered. Of course most of us don't get disposal info with batteries but I guess the best method is to discharge using a 12v globe (maybe in an outdoor concrete block), and then twist the +/- wires together before putting in salt water for a week.
I wish Class D fire extinquisher powder was sold in small quantities just for the extra safety, but sand is free.
Thanks guys, i just ordered everything needed to make your Batbone Tri-copter I can not wait until i can get to build/fly it
Hey guys! Thank you for this video. I have often searched the Internet for important information and when I find it it is in terms that electrical engineers can understand. Thank you for the easy to understand (ETU) that you've provided. :)
FliteTest You guys don't have a Chargers video. I would like to see a video about Chargers. Please do a video on AC Input, and DC Input Chargers. I'm mainly interested in AC Input Chargers.
Nice video guys, really informative about batteries. I find that using nitro engines on planes is much more less of a hassle but I'm old school. When I started flying rc-planes there wasn't really electric motors, planes around.
Appreciate the battery safety tips in addition to spelling out LiPo terminology.
Where's those calculator links?
exactly wheres the calculator
Thank you! I'm new to Lipo batteries and it is helped me out a lot. But one thing I didn't understand yet: How do I know the health of my battery, how exactly can I determine if I can still use it? (I use 2200mAh, 3S 11.1V 25C and 35C) It would be great to get an answer for that.
+Ido Kuttner If I may reply, get a capacity checker. You can find them on Ebay for real cheap (around 8 bucks). Do a search on lipo checker or meter. It tells you the status of each cell and how much it is discharged.
I always forget to like but not today this flight Test series is very helpful thank you guys
and 10 minutes is a decent flight length too...
ref: 2:40 ish
Thanks again Joshes for your work in our favorite family fun hobby!!
No words about internal battery resistance? Long non-use of lipo battery? But it's a great lipo beginner video!
I’m going to make the assumption that since Amps (Amperes) is current, the “C” may stand for current. Don’t take my word for it as it is just a guess. Thank you for producing this series, I’m learning heaps and soon my mate Spade who got me onto Flite Test will be teaching me to fly, Helicopters I can fly but planes he’s going to teach me :)
LOL, both informative and funny. Thanks. I enjoyed it even though I'm pretty familiar with batteries. One of the best battery explanation videos out there.
Im going back to IC. Cant be arsed with all this stuff!!!
A very current topic.
They are crazy important, what is more important, wings, motor? Is there insane crazy important? Good video, good info!
Thanks guys, you have really helped me and a lot of other people! My super cub should be in the air soon. Thanks again! :)
Excellent video guys! I am enjoying these beginner series videos learning lots of useful information. Keep up the great work.
Excellent information for novice. Thanks for sharing.
Rather interesting question: In almost everything I have read about LiPos there is mention about charging and storing in fireproof containers... Yet, I never see it explained in detail and I never see anyone actually doing it that way.
So..
1. Do you recommend sticking the battery into a fireproof bag while charging?
2. Do you store batteries at storage-voltage in a fireproof bag? I so, 1 per bag? As many as you can fit? etc?
actually what i do is that I put all my batteries in a surplus ammo can, it is pretty fire proof that if one of them or all of them caught on fire, nothing will pass through it , actually i transfer the batteries by my car while they are inside the ammo can (even the life battery for my Tx) ... i don't have enough fireproof bags to put all my batteries in , but the 2200 mAh is in one fireproof bag....this is for storage
for charging , i put the battery in a fireproof bag and charge it, then remove it and put another one inside it and charge it .. for more safety,, i put the fireproof bag inside a trashcan , it is metal and that because i charge inside my house and i think that is much safer
***** Thanks for the advice. I've been looking at ammo containers on eBay. Will get one soon.
biglightbt Good to know, thanks! I'm very careful about all those things. My comment was a few months ago. Since then I've learned a lot. I am getting both a lipo bag and an ammo case, just for extra security. But currently, I'm flying a couple of batteries and I'm simply treating them nicely and never discharging them under 80%. Again, thanks!
as a chemistry student that has seen some serious shit go down, including eight lithium cells shorting out and burning, meh. the fire hazzard isnt too bad there is a ridiculus amount of lipo cells out there, we dont hear about them all burning/exploding all the time..
I use the BAT-SAFE to charge and store my batteries. They are $50-60, and well worth the insurance. You could put a paper towel on top, explode the battery, and the paper wouldn't catch fire. As importantly, it will filter the black soot out of the smoke. The fumes are still extremely toxic. If your battery blows, even in a lipo sack, you will still experience massive smoke damage, even if nothing catches fire. Before I owned my bat-safes, I used to charge my batteries in my oven.....with the oven off, of course.
Josh & Josh; Really Nice battery Review & Thanks for all the information ! Thanks for the Video
I would like to see a video on how to chose and set up batteries with your equipment..like can you use your battery on a quadcoter for a camera and motors at the same time? What are the option..Thanks for your great videos guys..
I had a 4cell battery that was in perfect shape brand new but one of the calls was low and it wouldn't charger so I decided to carefully remove the dead cell. And let me tell you that battery was perfect after that. Now it's a 3cell and runs great.
Do you think you could make a swappable EDF?
Thanks guys,good episode.
Good show for newbies. Keep up the good work
I may learn this stuff yet! LOL Thanks guys!
Great video guys! But you guys should have covered storing you lipos for an extended period of time and putting them into storage mode at a voltage of
3.80 volts per cell other wise if you leave them charged or discharged for a week or more they can start to break down and puff on their own. I always put my lipos into storage mode even if im only going to be waiting 2 days until the next time I fly. I have been flying my custom built H-Quad for almost a year now and I'm still on my first set of lipos, but I did have one get punctured and catch on fire in my hours. Talk about brown pants level scared. I was lucky that I reacted fast enough and grabbed the battery by the wires, jumped off my balcony, ran out the front door and put the garden hose on it for about 10 min. BE SAFE WITH YOUR LIPOS, OTHERWISE YOU WILL CRAP YOUR PANTS!!!
Great video guys! I wish I saw this about 2 years ago. Luckily nothing bad happened. The online LiPo explanations can be daunting and very confusing to read for beginners.
I typically stop flying around 3.6 mark, some people even say 3.7 is empty.
Yeah, I always recommend not discharging past the nominal voltage, land at 3.7; that's close enough to following the 80/20 rule. I teach that in my Multirotor 101 classes.
Sometimes its hard to judge the voltage since my fully charged 5a 3s goes down to 4.0v the moment I get in hover. And if I land at 3.65v the voltage returns to 3.8-3.9v. So is 3.7v in hover empty?
Thanks for reminding about the dangers of life with LiPo's
Great video and all, but I don't get the title- what does "safety" mean?
I remember as a kid I used to leave lithium batteries sitting under the hood of my car while they charged and just forget about it for hours. It's a miracle I never burned down my house. I used the old Thunder power lipos without a balance lead too
Man batteries suck!!! Cant wait for better capacitors
Damn, this is important information. Big Thanks!
I'm hooked now, great info....again
Thank you very much! I am always confused in C rating. :)))
Thanks very much for posting this.
I wish you guys would go more in-depth on how to setup a charger's charge rate safely. In addition, I think you guys should have mentioned LiPo fire proof bags as an extended safeguard.
Yes, you can check the Viewer Request Speed Challenge episode in the end, they crashed nose down
You guys are very helpful thanks 😊
I'm surprised the A123 cells didn't catch on for RC. I've made a few packs from those and they work great, and they are nowhere near as prone to damage as LiPo cells.
Thx much, good info all the way around
"Sand is the best thing to put out a Li-Po fire..."
And in one of the Spitfire episodes they used a dry chem extinguisher, AKA the Grim Reaper of electronics.
Great videos for a noob like me. I'm considering buying additional/bigger batteries. (Current flight time is about 6 minutes.) I have motors with brushes and I've heard I need to let them cool between flights. How long should I let them cool and if I get a battery with more capacity, is that going to destroy the motors? Thanks in advance!
I resurrected a 2s LiPo that was on my quad connected for a few days between when it flew away and when it was found and returned.
Soo... Is this still Season 4? I'm confused, this is the first episode that doesn't have Season/Episode numbering, and all the later ones are without this information. The UA-cam account "Flite Test" has Season 1-4, and also extras splitted out in season 1 and 2 (promotions, quick updates etc).
Is 1 season = January -> December?
When will the rest of the videos get this information?
I have a 3 cell lipo that was slightly melted by a soldering iron. Should I still use the battery? If not then What should I do with it?
Also, where in a house would it be safe to charge or store it? Do I really have to put it in a bucket of sand or a fireproof case when I charge it or can I just put it on a table?
Now you've made me worry that my house will burn down if I keep batteries inside.... what if a battery explodes.... you mean I now have a load of active time bombs in my house that could catch fire at any moment....?
good video guys, but, you forgot to mention what is the storage voltage.
Got a question. I got my new Turnigy nano-tech 1300ma,11.1v 3s battery. I checked the the voltage(at the xt60 plug) it reads 11.4v. Is this safe? Also should I do a discharge and or balance cycle with my charger first before doing a first charge? Thanks in advance for answering my noob questions!!
Just figured it out i think.
thank you guys very informative
I wonder when you guys are going to do a video on battery swap mods like using 18650 batteries in place of stock Li-Po packs you find on most quadcopters and such. Want to see if a quad can use one of these in place of a stock 1S battery.
Very Nice.
Hey guys! I am brand new to the hobby. I still don't understand my strange attraction to flight but whatever, I think I'm hooked! So, my Horizon Delta Ray just arrived and I'm reading the directions. I come to the battery charging section and it tells me that I can get an AC adapter for the DC car charger and the amps limit should be 1.5A. I aready knew about about the AC adapter and got one from Horizon, but the amps out is 2.2A. Will I hurt my Delta Ray batteries using this AC adapter?
You guys are awesome! "Is this more math"..lolol..I Can so relate to Josh Scott. Would you guys recommend the lipo battery bags I've seen advertised?
Some thoughts on storage voltage would be nice. 3.85v per cell is what i understand. Question is, is the a certain amount of elapsed time when you should consider putting the lipo in storage state? I would imagine if its only going to sit for a few days, might as well leave it fully charged...
Nice video, but I was hoping you could address static current readings vs. under load. Do I land when the voltage gets to 3.3 volts during operation (ie via connected volt meter), or do I go by the reading on the ground after landing? Hard to find consistent info on this point.
excellent ! a great help , thank you for posting .
Great job guys when are you guys going to do another give away
I was kinda surprised you guys had a lipo charge bag and didn't mention what it was, might be worth mentioning
Thank you!! JUST THANK YOU for doing this shit seriously! We know you don't get much money from this etc. but seriously you guys are the best! You raised my Head again after crashing my first plane on the first flight. Gonna build my own now :D And thanks for the free plans on your website. everyone else would make money out of them and you give them out for free. Thanks.
Greetz from Switzerland
You sir said it. (My Bix3 is in the mail and I can't sleep :)!)
I have a question my charger says 12v 5a is it ok to use my wall adapter that is 12v 1a???
HalfDeadKC FPV can you adjust the charging amp?
What about the proper way to store batteries? Is it okay to charge them up then store them somewhere safe? Is it better that after you've discharged them to simply store them safely and only charge them before you go flying?
I just took a course in electrical engineering and I'm confused by volts do you mean something else? Because amps is the speed of electricity , volts is the pressure of electricity, watts is the amount of electricity
Guys, your videos are awesome, thanks!
I have 3 batteries with 7.4V and 2500mAH each!
Can I connect them (2 in series and 1 to others 2 in parallel) to have 14.8V and 5000mAH?
Is this a good idea?
Do they last for engine with 3500KV, 55A and 850W?
Got the same question about how to storage lipos. Charged or uncharged? for longer or shorter periods like months and weeks. Also what is the best way to storage lipos? i got a special bag when i charge and when i storage them when not using the lipos or is there any better way to storage like special boxes ect thx in advance!
Wheres the link to the calculator?
The Video quality is very good for a 7 years old video
Somebody please answer this. If I got a battery that's way over the c rating I need for my quad, can it still fly safely? Say i can only pull 64 amps far extreme yet I got a 40C (82 amp) battery?
Hi you guys... about the chargers (forgive me if that's a stupid question), you mentioned the different types of chargers (balance cable and regular one). Is there a charger that uses both simultaneously? To charge it quickly AND balance it at the same time?
Forget about it. Should have watched the whole video ;)
Does C stand for the amount of coulombs you can draw through at a certain time?
+Kyle McLester probably. an amp is 1 coulomb per second
+Kyle McLester no. That would be amps. C rating is a value used to find the watts the battery can provide. I think c rating is a superficial number only pertaining to lipo battery cells.
+Kyle McLester Since amperage is a measure of current, surely it would be safe to assume c rating means maximum current rating.
maximum current(A) per unit capacity (Ah)?
C appears to be defined such that the maximum current in ampa the battery can safely deliver is C times the capacity in amp-hours.
Josh's shouting voice is softer than my moms speaking voice.
Will a LiPo battery discharge during storage? If so. What is the proper way to store one?
Whats with the 6S at the end that's got the Red and Black leads connected together? I know that particular one it isn't the main leads but it did look like it for a second. What happens when you accidentally connect the black and red. Big Flashes and Fire instantly. Beginners Guide - Safety, No mention of shorting or cutting leads You missed an important little detail.
is it ok to keep the battery fully charged even if I'm not gonna use it right away? And don't leave the charger plugged in. I had one catch on fire.
My AeroScout Mini's motor drops to half thrust after the battery is done and a LED starts flashing on the board, and when the motor drops to 50% power when im at 100% on the stick, i cut the power and land.
How do I store batteries? In a lipo bag obviously but how charged should they be? And if I don't have a charger that smartly puts it at the specific charge level how do I get it there?
So I have a couple handfuls of those little baby 1s 150mah batteries that I can't use anymore. So, to dispose them properly, soak them in salt water and then?
