Thanks. It's great when people give this courtesy.
Using this video as learning material for a report and having this break down is massively beneficial! So thank you. AND THANK YOU TO READY SET DRONE FOR MAKING IT MOST IMPORTANTLY!!!
I love "Ready Set Go".Dude your channel is very informative.
I’m a rc car guy I watched your 8 min video on PS4. Great video very informative and to the point, thank you
I bought a cajun commander, the manual says to put a 3s 3200-5000mah 25C battery in there. Is it ok to put a 6400 mah battery in there?
Thank you! Very informative.
What battery would you recommend for a electric longboard running two 6374 180kv motors ?
So im thinking about modding my XS809HW Visuo quad copter which takes a 3.7v 900mah battery. I want to put a 2500mah battery on it but the ones i see that are for rc's are 7.4v. Does this mean i cant use that type of battery because the volts dont match up? Would i have to use a cell phone or gps battery that is 3.7volts to power the drone?
I want to get a higher mAh battery for my quad. So I match the volts, (s) and C. I notice that some batterys just say high discharge but don't give a C rating. My original battery is a 20 C. Do I have to match that or what is considered high discharge? Thanks for any help you can give me.
Very good presenters, thanks for the video! :)
I have a 60 A esc for a model I'm building. Is it safe to use a 60 amp 4c Lipo? Additionally, the motor is rate at 2650 mha. What is the best combination
When should I land a quad that’s has a 4 s battery. Is 14.0 a good voltage to land what’s the lowest voltage I can land so I can have longer flight times.
awesome info!
These Camway 2 and 1voltage tester and alarms how do you get them to fit in with 1 cell battery
so you can hear the alarm in a
plane like a Sports Cub 2, The Champ, and so on.
Thanks for the great video
I bought a portable car battery jump starter. At first it was able to jump start 2 cars with almost dead batteries. After 3+ months, I tried them again but it won't start a car again. Voltage on the output is at 12.6vdc fully charged but I think the current is different than brand new. Can I dismantle the lipo battery from the case and charge it using the lipo chargers you showed here? I believe the portable car jumpers also use lipo batteries.
Awesome info!!
Very good information. Thank you
Some battery packs have a bulkier profile and won't fit in certain compartments. I recently purchased a Kyosho Fazer MK2 GT3 and I wanted to use my 3s battery pack from my Losi Tenacity DB 1/10th scale but the battery pack was a taller profile battery pack and wouldn't fit under the plastic battery holder on the Kyosho Fazer. Question: When looking online for a battery pack, looking at numbers printed on the battery pack, how do I determine what is going to fit in my RC car? Or can I determine how it will fit in my RC by looking at the numbers on the battery pack?
THANKS ,maybe a bit to tech for me but the safety concerns were well noted.
Wow! Kelly 6 years ago. 👍 I really like this video I refered this to alot of newbies in the Fpv hobby. This one is my favorite ones compared to others on UA-cam. Perfectly explained. Brother. See ya at Spinup🤘
Great video👍
The goldmine right here boys.
This was super helpful! Thanks
Glad it was helpful! It's an older video, but still good content. Probably need to update it some tiime though!
What I've never seen explained anywhere is how to choose lipo batteries for specific setups. For example, Say I have a Brushed E- Revo and want to run LiPos. ESC handles 16.8v. Which LiPo setup would be best? 2S? 3S? 4S? 4S on each side or total (2S+2S)? If a 3S is 11.1v, can you safely use 2 packs or only one?
can u charge a battery at a charge rate slower than 1C. I have charger for 350 mAh charger so can I charge 650mAh battery
Again great video. A couple more questions/suggestions related to this video:
1) Jason forgot to explain what "nominal" battery charge means and it's relevance. He said he'd come back and cover it but he never did. I know that for LiPo batteries the nominal charge per cell is 3.7v vs a full charge of 4.2v but beyond that what is the relevance of it. It might be worth adding a note in video description.
2) Jason mention something about a "beeper" that you could add to your quad...but he never explained what that is or what it does.
3) Towards the end of the video there are various battery accessories (chargers, load testers, etc) that are shown/referenced. It would be nice if the specific product names and ideally the links to purchase those products were included in the description for this video. There a plethora of these products out there and it can be overwhelming to know what to actually look for in a product like this...so it would be nice to give a newbie a specific solid product recommendation as a reference.
4) There was no discussion of the LiHV (Lithium Polymer High Voltage) batteries. I believe some of the new quads are coming out with these type of batteries (e.g., Fimi A3). These batteries charge to 4.35v per cell and are smaller/lighter than standard LiPo batteries. One of the advantages of this type battery is that you can pack more battery capacity in a smaller and lighter battery...which equals better flight time. I think there are some downsides as well (e.g., non-linear power drain rate...LiPo batteries drain at a very reasonably predictable linear rate which is great for projecting battery voltage levels during flight). For completeness it would have been nice to have covered that type of battery as well.
11:21 "voltage from Voltaire" wow Alessandro Volta is spinning in his grave
he probably has a degree in physics
It goes with the smaller JST connectors that "will handle 12 Volts of current".
Hardly, maybe he is a biologist or statistician.
And @ 3:52, "12v of current".....smh
Voltaire? Really? The minute I stopped watching this.
if charging is through the skinny wires, then why do we need to hook up the 2 thick wires?
New to FPV, so this was really helpful. Is there video that explains charging. IE I plug my 4s 1550mah battery in, say its 15.1v I out it on balanced charge and when it says full, the C is sitting at 0.0, Voltage is 16.8 but the mah on some batteries are as high as 303mah. Yet some (new batteries) go all the way to 0.
What does this mean? IS the battery on its way to death and should be discarded?
Thanks
Hi I'm new in the hobby , I got a noob question which is :
If I run a 2s 6000mah 50c battery with a 150A esc and a 1200w motor instead of 3s 6000mah 50c battery with 150A esc , the calculation shows that Watt/voltage=amps (1200/7.4=162Amps ) on 2s and (1200/11.1=108amps) on 3s , does that mean it is safer to have a 3s instead of 2s on that esc ?
Thanks for informative video!!! Just a question with my TB6 charger....while I’m charging a 7.4v/1300mah in 1v chi.mode, in a couple minutes it starts reading 8.4v so I frantically stop it , am I doing wrong here or should let it go on......help lol...thanks!
So I _think_ that it is OK because a 7.4v battery is only actually 7.4v average, meaning that it will charge to a higher voltage (like 8.4v) and then discharge to a lower voltage (like 6.4v). So I think you are OK.
Ready Set Drone thanks!! I’ll let you know what happens lol
Just subbed.. I am really new at the game.. Is there a difference with the hv batteries?
Question....I have a 4s battery, says 14.8 volts as it should (its a dynamite reaction 2, 5000 mAh, 50c) Anyway, the storage voltage should be 3.85 x 4, or 15.4 volts....correct? I just dont understand why the storage voltage is higher than the 14.8 volt rating of the battery?
Is it normal that one cell turn on green light but the others are still red in 3s lipo battery?
how do i trasport those lipos save when i am gonna travel with the plane?
watch rotor riot's video on traveling with lipos
K, so I live In Hawaii and i have a few questions. I really want a lipo, but how will i get them if they can't ship them in cargo? Also, I wonder if even my house is too hot to store lipo batteries. I'm pretty sure it should be fine in my house, but you never know.
Hi Steve. Lipos can be shipped, they just have to be labeled properly. I get them shipped to my house in Texas all the time. Also, I keep them in my garage, which can get hot (probably 90 degrees in the summer), and have never had a problem. You can store them in Lipo bags, which are supposed to keep them protected. Hope that helps!
I fully charged my Lipo batteries and didn't use them for a month. Then I found them to be slightly swollen; about 1mm in width each. I noticed because they barely fitted before, but now about 2mm off. Do you think its a very bad thing; or they may return to normal.
Abdel Rahman Labban They will never go down until they explode. Not a good thing. They are expanding because of too much heat and age. Take care of them by charging and discharging them according to instructions and they will last 30 to 50 cycles.
if you want to store a fully charged lipo atb least keep in the fridge...
Great video, thank you. and wow, holy crap, that means my tiny 1S - 150mAh can draw 3A ! Impressive for such a tiny thing. But I see "3C max charge rate which would only be 450mA"
Hello i have the walkera 450 do3 helicopter the ESC is 40 amp the máximum capacity is 55 amp , and i want to use the multistar 5200 10 C , the power of the baterry 52 amp so thats ok ,
I found the short version of this video more informative actually.
In this video they didn't delve into storage charge and took much longer to get to the basic info.
No insult intended just my opinion.
Fantastic video. Okay dumb question for clarity:
@ ~16:00 your guest said " 'C' is the amount of current that you can 'safely' draw out of your battery at one time." By "safely" I assume he means this is the maximum amount of current that you can expect to get out of the battery at any one time...there is no safety issue if you were to try and draw more from the battery, right?...other than your drone might fall out of the sky if your battery can't deliver the current that your drone needs. Just asking for clarification.
Hi,
Great video. Do you know how to calculate Battery charging time?
For example a battery with the following specification (Full charge drained to zero):
Capacity: 10,000 mAh
6 S
Max Charge rate : 2 C
Constant Discharge : 10 C
Thanks.
I don't know the formula for this, but I did find a couple of online calculators that seem to give the answer. Google "calculate battery charge time" and several Java sites come up where you enter values and it give you an answer. Hope that helps and thanks for watching!
Does it hurt to keep your li Po battery plugged in all the time when your not using it?,
It depends on your charger. If it is a "smart" charger, it will not hurt the battery. But if it is just a plug that goes into the wall, I would not leave it plugged in all the time.
Ready Set Drone it would be the one that came with the DJI P3 S
Wat kind of charger are u holding there. I think i am going to buy that one
Tenergy
What is the lowest voltage I can run my 3s Lipo battery? It is a 5200 50c.
Maybe 9.0 volts. But that's just my best guess.
@@readysetdrone Wait sorry didn't understand 9.0 volts. What do u mean by 9.0 volts?
@@readysetdrone Also it is a 5200 mah. I am running it on an rc car.
Is it possible to mix batteries together(11.1v/50c & 14.8v/100c 3s)?🤔
I wouldn't recommend it. 14.8v also sounds like a 4s battery, not 3s.
@@readysetdrone Running Traxxas Sledge with (2)3s 5200 mAh 11.1v each @ 50c. Is it possible to bump the voltage slightly, yes? And would the 4s 14.8v batteries be to much voltage combined(29.6v) or could I mix 11.1v & 14.8v together(26.9v), but my only concern then is discharge rate. Could I use a single 6s 5000mAh 22.2v @ 100c? I appreciate your time and skill. Just concerned of damaging electronics.
You’ve explained how to choose. What about how to buy ?
12volts of current?
Finally found it.
I just received my x8g, and charged the battery twice. Both times, I plugged the charger into the wall first, and then plugged the battery into the balanced charger, and the green light never shut off after 200mins which is the approximate est for completion. I actually ended up charging the battery for about 4hrs before I finally said that's enough.
Well my manual had two instructions. "Plug the charger to the wall and THEN plug the battery to the charger" and "plug the battery to the charger and THEN plug the charger to the wall". So I'm wondering if one of these two choices is why the green light never shut off. I guess the route I went the first two times were for a "balanced" charge.
I have the battery charging a third time by connecting the battery to the charger first before plugging into the wall, so I'm hoping the green indicator shuts off after completion this time.
Sorry for the long post, but is this common? This is my first drone, so I'm very new to this.
Seems I reached my limit lol
Anyways, I must add that I used the battery both times, and quad flew fine, so all seems well, but I'd like my charger to let me know when the battery is completely charged, rather than guessing. Also, there were two (very rapid) power outages when this happened. Power went out and came right back on, due to the weather.
Any advise??? Thanx a million.
Seems like the battery charger is pretty "dumb"...
If you have a voltmeter or a battery tester you can easily tell the state of charge of your battery.
I would do two things, get a battery tester first to see if your charger is working at all
Then get a good charger so you don't have to worry.
"look at the brains on this guy" "yeah I know, math is hard" hahaha
With the market flood of battery manufacturers, how can you tell good from bad? Or at least lower quality. Is it as simple as you get what you pay for? Is there even that much difference between them?
I think it's like everything else - you have to go with the better known brands. If you order batteries from HeliPal or GetFPV, you should be fine. I would also recommend keeping tabs on individual batteries. I sometimes use different colored Sharpies to mark them after each flight (green mark means it lasted as expected, red mark means it fell short somehow - too many red marks and I dispose of that battery). Thanks for watching!
Ready Set Drone h
i think Limskey battery is very good
A negative, not a ground. Great video though 👍
Can you explain what you mean? Im trying to learn
30 minutes of talking and the most important thing you guys didn't said! How many cycles those LIPO battery's is going to last!
batteries
10:33
Using hose anlogy:
voltage=water pressure (measured in volts)
currant=how much water or electricity there is (mesured in amps)
resistance=how fast the water flows (measured in ohms)
8:59 "S" does not equal the number of cells. "S" equals "series". The number before the "S" equals the number of cells.
Warning: If you try to cool a battery while charging it with ice or ?? It will explode on you and create a vicious fire. The result of a chemical reaction. That is why the charger instructions recommend charging while you are present and check the temperature occasionally.
Good to know!
3:52 into this video "they will handle 12 volts of current" hmmmmmm. Now that's interesting. That quote does not make any sense. Also, Lipo is not a chemistry but I do believe that RC Lipo chemistry is LiCoO2 (Lithium Cobalt Oxide) and stability of a cell is affected by it's chemistry. And some RC items also use LiFePO4 (Lithium ferrous phosphate or Lithium Iron Phosphate). This detailed version has some ........well.....less details. People watching this video..... Please do more research to understand Lithium Cell Technology and how to safely use/store. :)
Great points. thanks for clarifying!
im watching this for airsoft, still thanks
I watch your video to learn about the B6 battery charger . I learned nothing about that. You remind me of someone. They killed themselves by the time they were 55.
I cannot help myself...
For the record, let it be known and corrected that flow of charge in circuit theory ALWAYS is from positive terminal of battery to negative terminal (and across any other such component) NOT the other way around. Please take a look at a diode... charge will only flow from the positive (anode) to the negative (cathode). An anode by definition donates electrons to the cathode.
It is by convention in circuits (nothing else) that the positive terminal is such. It is ALWAYS the case that electrons flow from higher energy states to lower energy states, such as the ground terminal, or negative terminal... I mean have you ever changed a car battery? Most every battery, power source, etc. will have the positive terminal as the hot terminal and the negative as the lower energy terminal, usually grounded. These guys are definitely not physicists. They are confused because electrons are negatively charged particles, so you might want to think they are being sourced from a negative terminal. But the + and - designations in circuits and components have to do with energy level in the circuit, not particle charge. Long video for a lame battery intro. Should leave the circuits course for LinkedIn. They have some real simple and short videos that are accurate.
BTW, in the water analogy, "getting hit with a lot of water through a tiny hose" is NOT analogous to Tesla coil experiments (high voltage but low amperage)... that would be more like water falling from thousands of feet up in the air to your face... some call it rain, totally harmless, since Voltage is the pressure driving the electrons, not the amount of electrons.
Electron flow vs Conventional flow my man. Look it up, they are not wrong - they just explained the electron flow. You were close though, do a little more research next time lol.
Boring there is no explanation of LIPO Batteries just a listing of Connectors and different battery types
Get the title of your video in order
Check the guy in the red, how many times does he have to read the laptop..... OMG
So? SMH
