I think its more like this:
- Voltage is more like the height of the water level in the tank. The taller the water level, the bigger pressure in the bottom of the tank
- Capacity is like the volume of the tank. You can have 2 tanks with same height (Voltage) but have different volume based on the area of the tank base.
- C rating is how big the pipe in the bottom of the tank that determine the maximum flow of the water. BUT the actual water flow will depend on the valve (load) in the end of the pipe
“barely dribbling out the end..” is that what Le Drib means? Ha ha that low voltage drip 💧
the way i look at C rating is like the red line on your engine RPM, you can put the throttle down but it might blow up if you have it pinned for too long. lol
Well said man
does higher C rating help not blow it up or increase the chance of that?
Examples would be nice
World record for the amount of times the word battery is said in one video
I enjoyed the video. I like how you use the MPC as much as a musical instrument that is played and not just as a “machine.”
*maschine
anyway, does he produce the background music himself?
So your water 3 was a little incorrect. Capacity is like you said is how much is in a storage tank. The voltage is going to be kind of like the size of the water hose you're using so how much water is being carried through the different sizes of hoses that you use that's voltage. And then the intensity of the water shooting out of the hose is going to be amperage. So you can have a big hose with low amperage and the water is not going to shoot very far same thing with a smaller hose with low amperage the water is not going to shoot far either. Now going back to the big house if you have higher amperage then you have a heck of a lot of water (Volts) shooting out at a great distance with a lot of force (amps). And same thing with a smaller hose there's less water (volts) but you can still get that water to shoot at a far distance (amps or current). Current is the rate of charge flow so use the principle of Ohm's law to get your values. Look up ohms law for more info. I could go on all day so check it out. Learn more. It greatly helps you
Capacity is amount of water in your tank
Voltage how big the pipe is coming out of the tank to drain it.
Current is how much you can open the valve to allow the water to flow.
I think its more like this:
- Voltage is more like the height of the water level in the tank. The taller the water level, the bigger pressure in the bottom of the tank
- Capacity is like the volume of the tank. You can have 2 tanks with same height (Voltage) but have different volume based on the area of the tank base.
- C rating is how big the pipe in the bottom of the tank that determine the maximum flow of the water. BUT the actual water flow will depend on the valve (load) in the end of the pipe
I was just about to buy a 4s 200c lipo battery when I saw this video! I have definitely learned first hand everything he said is true! I have a 4s 120c 1550mah that gets longer flight time (both cinematic flight) than my 4s 100c 4000mah! Thank you Rotor Riot!
I don't know if RR read these comments or if RR have covered this already, but as part of this series RR should cover video channel selection for flying in a group. i.e the number of pilots possible at one time on which particular channel and power output. It's not as easy as every one setting to 800mW and putting 8 pilots on raceband and this is not obvious when starting FPV.
the lift off sounds tracks are imbedded in my brain
Look up "battery mooch" on youtube. He is the vaping worlds premier battery expert. He talks in context of 18650 batteries but the principles are the same.
I know this guy from reddit. He is a god!
Great Video!! If i have a 1400mAh 22.2V 6S1P Lipo Battery Pack with XT60 Connector, could i use DJI FPV AC Power adapter to charge it? DJI FPC power adapter is the one i use to charge my DJI FPV drone battery. Please advise. Thanks.
Cnhl 4s 1300 mah battery or 1500 mah ?
Voltage is like the water pressure
I can't find a direct answer but is there a limit of battery cap I can use on my 6s quad copter, like I know a 6000mah is heavy and will reduce the flight agility and all that, but can I go that high or higher cap? Like will a very high cap battery damage anything?
Very informative
Hello, are you a drone battery supplier?
I need to know what these brands are
Goldbat Lipos on Amazon are good and cheap. Battery performs as it should. Got 4 packs of 1300mah 4s 100c for about 70 bucks, the batteries fly nice, but I only have about 2-3 cycles on each. Let's see what happens in 6 months.
10 months later. Whats the verdict?
4 years later. Whats the verdict?@@derekburton7648
3.7 to 4.2? I dont use lipos but i always heard ppl using s cutoff of 3.3v... i use 18650 batteries instead and cutoff at 2.7v per cell...
would a 2s or 4s made with 21700 3.7v 30a 4000mah battery's be ok for a novice iv
I need a 10-15 min flight time for a 5 inch fpv so which battery can i choose?
depends on the drone, motors and esc.
get a flywoo explorer 4"
Good info.
Just a comment on how it is put across for future maybe. Just a bit boring to listen to so much info with no camera changes or examples or anything like that. To have to sit and try absorb as much monotone info as possible is a little challanging. :D
Really appreciate the help all round guys thanks!
You forgot, a good thing for batteries are those cheap battery checker- buzzers. You can mount it or just plug it in and strap it with the battery.
Most people would just use their OSD to monitor their voltage. You can configure warnings and everything without needing to strap a buzzer to your balance lead
I'm looking for the best reliable LiPo battery
does the background music is the same than in LiftOff radio? if not what is the name?
It is the one from Liftoff
How much time should i wait to charge batteries after flying while they are still warm and should i whait?
Lord FPV until they are room temp
they say tattu is one of the best, that might be so for light drones.
i had some for my 5inch tmotor ft5 hd, they have no punch left at the end of the flight.
1300mah tattu 200gram
1300mah dynogy 242 gram, much bulky er.
i found out that dynogy is much better and has almost all its punch left til the verry end.
unlike those light thin tattu batteries, i think they are only good for light drones mabe.
also the 6 tattu batteries wil verry easy turn to 5s
Thunderpower sucks now but they used to killer. Payed $300 5000mah 6s 25c 1000+ cycles got one a couple years ago 55c done after50 cycles and they refused to replace it.
thanks guys
How many barriers should I buy?
i settled with 8 wich gave me 40 to 45 min flight time, with small breaks u wil have about 1 hour 30 min of fun
did he just say 3.7 at dead??? has my man never flown a tiny whoop lol
Gautam Krishna lololol
LVT Latvian I remember Steele saying 2 years ago he flies down to 3.7v for batteries. Just look at his dvr now lmao😂
Gautam Krishna My tiny whoop drops to 3.4 when I take off
Hattash Fpv I’m on holiday and the only 1s lipos I have are super worn and swollen and I fly them on 2s (they wouldn’t survive 1s) on mobula7 and instant sag down to 7.1v from 8.7 (I charge to hv)
@@HattashFpv Try replacing your stock PH2.0 connector with a solid pin PH2.0 connector. If a brand new battery is going down to 3.4 on takeoff, it's likely your pins are worn out and need replacing. Solid pin connectors won't wear out and are a good permanent fix for instant voltage sag.
Thanks for the info!!
If it says use 50-85c could I use higher? I’m a beginner??
No, that range means at maximum voltage it will have a discharge of 85c and when almost empty (low voltage) it will be 50c
What’s the intro song
yo lakey beats!
Thanks for the great info... but sexy time music is not working for me...
the music is from the game/ simulator liftoff
Can i use a 4s lipo on a 3s drone?
Short answer, probably not a great idea... Long answer.......That depends on the electronics - if the ESCs are rated for 4s or higher, that is a good sign.
But you also need to consider how the other components are powered - if the flight controller is powered via 5v or 12v regulator, then you would be safe, but if the FC is only rated for 3s and receives full power, you will likely blow the FC. Same concept for VTX and camera.
Next thing to consider is that the motors spin to a certain RPM depending on the voltage - applying 4s will make them spin much faster than 3s.... I have heard of people using 4s motors on 6s by adding a throttle limit, as long as all of the other electronics can support 6s.
Finally, PID tuning and filters will likely need to be changed to fly with the same smoothness that you are used to.
I hope this has helped to at least point out some of the concerns to look for.
@@TommyGFPV Thank you for the answer! So it is a better idea to built a 3s drone with 3s lipo or a 4s drone with 4s lipo. Because im a beginner i would built a 3s drone first and upgrade later the parts in order to switch to 4s. What do you think about that? I also read that you can power a 4s quad with a 3s lipo. Is that possible?
powering 4s quad with 3s is how I got started! Then you can upgrade batteries later, but in the meantime you just aren’t using the full power available... which is a good thing for beginners! Many may disagree and tell you to jump right in, but I found that I needed the practice and it made me better at flying until I actually needed more power. I practiced a bunch on 3s, then slowly started getting 4s packs. Then I flew my 3s first to warm up and ended the day on 4s.
The one thing that may or may not have an impact is running a 12v regulator - 3s can dip below 12v and then this power source may become unreliable. Most receivers are 3.3 or 5V, and most cameras and VTX support either 5V or full battery power though, so it likely will not be a problem, just one thing to consider
@@TommyGFPV Thanks a lot! Is it possible to get your instagram name, in order to answer my questions?
Valeaten 434 it’s “tgrelecki”, I’ll do my best! If you’re on Facebook there are a bunch of helpful groups (Rotor Riot Community, Heli-Nation, MultiGP Drone Racing Community). A lot of FPV pilots use Facebook for this kind of thing
I can't believe you said it. "(1:15)....they range from 3.7 at dead to 4.2 volts at full charge." Not true, at the low end they range from 3.1v to 3.2v depending on numerous factors. Fully charged they are 4.2v. Let's give Charles Coulomb some credit and demystify the C-rating. C does not mean capacity. C is the first letter of Coulomb's last name. He was a French physicist in the late 1700s and is responsible for Coulomb's Law; without it you would not have batteries.
What are the BEST Battery Brands?
Tattu
@@KwadLife True. The Tattu Fun Fly has been very solid for the median cost hands down. PYRO DRONE graphenes as well (^^)\m/
I really hate the water idea. My dad tried to explain it that way to me as a kid and it never made sense. Now I’m adult and an engineer. I would never explain it this way. But I understand why you did it. It’s what you were taught so pass it on.
Cool
SLS NoC batteries are said to be total awesome ^^ but i havent had one.. 😅
i know that song....
I can’t find any good (for me) drones for less than 400$
You probably won't be able to. Just pick one up and enjoy
Anyone else think liftoff is open when I watch these videos
That music is not helping this presentation. This episode has good potential, but I don't think the communication was clear or concise and if this is truly for a newbie, I think that this is going to overwhelm them before they ever get thru minute 10 let alone minute 17.
As a noob I am definitely overwhelmed they also didn't say what battery suites and examples would be nice
That background music sure is annoying. Please turn it down or - better yet - turn it off completely.
Most battery manufacturers tend to put their "Burst" C rating in big letters, then you might find the standard C rating.
Херня а не батки 👎
