disscharging is a way to safely cycle your battery. Lipo's do not like to be stored at full charge. You need to discharge them to around 3.8 volts per cell for long term storage.
S refers to the cell count. A 3s would be three cells, 2s a two cell. The C rating is the max discharge current. The mAh rating is the capacity of the battery
@SebastienDS Charge LiPo packs at "1c" or 1A for every 1000mah. This only applies for low discharge batteries less than 25c. Over 25c, and you could charge at 2c or more! So on paper, you could charge your 3800Mah at 7.6A if it is greater than 25c discharge. Some c ratings are overstated by battery manufacturers though, beware! If your battery doesn't have 12ga or larger wires, you should probably stick to charging at 1c or 3.8a no problem. RCtestflight is just being ultra-safe.
you can use any c rateing above the lowest recomended. but higher c ratings will cost you more and will weigh more. A good rule of thumb is to use 25 pecent more than recomended by the manufacturer.
Hey Daniel, I'm not sure if what you showed us was you actual charging setup or not but if it was I STRONGLY recommend you add a fireproof charging bag to your next hobbyking order. I NEVER trust ANY lipo battery when it is charging since one caught on fire in my room with a setup not dissimilar to yours. BTW I am 17 and burning the house down would not go down well with my parents, and it was only lucky that we were home when it happened because it would have demolished the house for sure.
@Kpilot786457 i dont have a link but some of those electric edf jets that pull a couple thousand watts and run off like 12s use some pretty crazy batteries.
@SuperMillerman10 It doesn't work that way. mAh is capacity, how much power the battery holds. Ampere is simply how much current you are delivering per second. The higher Ampere the faster the battery will load, if you put too much it will "puff up" and possibly ignite.
Use your volt meter on the balance tap and read each individual tap after chargeing. They should all be the same at or near 4,2 volts. Starting from the tap closest to ground each will increase by 4,2 volts. tap1 will read 4.2, tap two 8.4, third 12.6 and so on. Be shure you are balance chargeing as cells will go out of balance over time.
there is usually a C rating for how fast you can charge your batteries. with a 3.7 Ah battery with a 2C charging rating, you can charge it at up to 7.4 Ah. for a 200 mAh battery with a 3C charging rating, you can charge it at 600 mAh max. also, if you charge a 3.7 Ah battery at 3.7Ah, it will take ~1hr to charge the battery
you should do a video on power setups. I am bit confused on them. It seems you want the max amps in your battery than your motor should have least amount and your esc somewhere in the middle. Correct?
What's the connection between the capacity and how much current you can use to charge it? I would have thought the power rating would be more important there.
you also need to balance your batteries EVERY time you charge them. it takes 2 seconds more, but it will preserve your battery. Not balancing is more damaging than charging a 1000 mAh battery at 1500 mAh.
Great video :) But I charge my batteries of 3250mah at 5a and have done for over a year, they have shown no puffing, ballooning, or decrease in performance :)
When you charge your battery at a lower amp setting like you suggested, you did mention it charges slower. Does it still charge to full capacity, just slower, or will it say only charge to a certain percentage based on the lower amp charge setting?
Ive bought 2 Nanotech Lipo's. Both are 4 cells. 3000mah 25-50c and 3300mah 35c. Both of them puffed up pulling 56 amps on an 70mm edf Goshawk. Has anyone else experienced this? It doesn't happen if i use Zippy Lipo's.
@paintballkidz Just trying to do my bit and help some people in this world.... I bought two of these "Lithium Polymer Charge Pack 18x22cm Sack", one to test and the other to use. I purposely exploded a 2000Mah 3 cell in one and it got fairly warm on the bottom and made lots of smoke. The other one I use in confidence that my house is safe from a Lipo fire.... Just my 2 Cents :)
Hi , for an esc 30a I used 11.1v 3 cells 2200mha 35c when I connected the battery with esc burns esc is possible battery to be so powerful , i don't ave any knowledge about rc and battery. thanks
Your lipo charger should automaticly shut off at capacity. Should the charger your useing not do this than get rid of it and buy a new one. Hobby King sells some very good ones for very prices. Take a look at the Accucell8150. I use a few as field chargers but it wiold make a great home charger as well but you will need a power supply
Finding this video in 2023 after being a fan for a couple years!
i like this vid because other ones i watch its to hard to understand but this one is easy thx soo much

@alfwok the "s" in "3s" means "3 cells in a series" so 3s=3-cell.. If you see "3s2p" means 2x 3-cells in parallel.
thx:)
How about balancing a 3s 2200mah lipo. would you recommend setting the charging rate at 2.2 amps or lower?
I have some nano-techs that I charge at 10C and they do fine.
When you charge your battery at a lower amp setting like you suggested, you did mention it charges slower. Does it still charge to full capacity, just slower, or will it say only charge to a certain percentage based on the lower amp charge setting?
What is the torque on your motor or the size of the prop it can swing? Most motors at least tell the weight of the airplane you can fly it with.
Safe current = C rating * mAh rating.
So with 20 C and 1000 mAh, the max safe current is 20 000 mA = 20 A.
@rctestflight Why??? Those batt's are made to be charged at 1C charge. And the Nano-techs at 4-5C...
Ive bought 2 Nanotech Lipo's. Both are 4 cells. 3000mah 25-50c and 3300mah 35c. Both of them puffed up pulling 56 amps on an 70mm edf Goshawk. Has anyone else experienced this? It doesn't happen if i use Zippy Lipo's.
Does volts matter? I mean the plane comes with an 25 c 3.7v battery 500 mah. Can i use 25c 7.4 volt 800-2000 mah battery?
how much did that charger cost, and where did u get the batteries and charger? thanks!
@starwarsjazz no that would be good for it
@rctestflight
So i should try to make the plane lighter?
how do you know when to stop charging

@Snowbrdr020 full capacity
5000mAh 30C 7.4V LIPO good for 70mm ducted fan with 60a ESC ???
what charger do you have?
Hi , for an esc 30a I used 11.1v 3 cells 2200mha 35c when I connected the battery with esc burns esc is possible battery to be so powerful , i don't ave any knowledge about rc and battery. thanks
Could I use a 2s with a 950kv motor with a plane weight of 900g?
what does it mean when it say 3s 2s etc on a battery?
UA-cam decided to recommend the video after 11years
Is that rechargeable ?
what does discharge mean
why not charge at 1c?
@SebastienDS what?
@Discussd charge / second*. Not too familiar with the English terms.
I believe the 2200 nano-tech battery can safely be charged at 5C.
5C X 2.2 amps = 11 amps :-0
@SebastienDS ya but I wouldnt recommend it
do yuo need a batterie charger for these
@Kpilot786457 some do
can i get a batterie that has like 3 times the c that the batterie needs is that ok

Im getting scared more I watch because of those open knifes near the batteries
Say I have a battery that is 600mAh, 30 C, 3.7 volts.
Can I upscale it to a 2000mAh, 30c, 3.7volts?
I think so, so I will.
Did it blow your house up?
not_a_private_username txt I have mild incompetence. Just need to buy a bigger battery lol
So basically i can charge my 3800mah 6cell at 3.8A? thats cool, quick charge!
Btw 2200mAh 20c
@Peanutdinos3000 lower
@soccer4209 ebay
maybe i don't feel like it!!!
yeah but see if one lipo gos on fire all will go on fire in the safe
well i guess your right thx for answering
Where can I get them
Nice commercials
No Chris
Why don't you just watch the video? Jesus christ...
