no i tested it with it and am uploading a video(49% done,damn internet connection) but after using it i measured the voltage the first cell is 4.2 the second is 4.3 but the third is -1v ,how is this possible?
the actual readings were 1st wire-4.2v the second wire-8.5v and the third wire-8.38v
how is this even possible??

You are measuring voltage in reverse polarity man !

ok , now you say you have tried the hard way......but I don't think it's not time to discard it yet, no more tries, For now, You may risk it with reverse polarity or some thing PM your phone number, I will call you and help you out tomorrow evening (anytime after 1PM).

i dont think im measuring it in reverse polarity because the multimeter says + if i exchange the wires then there is just a - sign over the readings i think better is to discard the cell ,can you guide me through it ,will pm you my no. you can call anytime dont have school or classes tomorrow ,i will get a new battery tomorrow for the quad as i will have to buy it anyway
i dont get it people said the battery after discharging becomes puffed and heated ,this one was cold and the 3rd cell looks a bit puffed

Is it puffed? now?
Ok, A idea I got from Kalyanprodhan sir, pack your battery water proof and put it in your refrigerator- until my call tomorrow



Hey no, I am not trying to fool you  !!!!, I have my Two LiPos in my fridge right now, Kalyan sir gave this idea, he says fridge is best to prolong this unknown alien's life ime .

i have read his post, will do it, cooler or freezer?

I don' think freezer, Because I don't whant ICE !!, I only need my batteries back when I take it out,

Cooler will DO :8

On Load when the Cell EMF < I x R drop where I = load current and R = Cell Internal Resistance, the terminal voltage shows reverse.
For an rechargable cell, asfter complete zero, Active materials can develop in reverse polarity. And then only even after disconnecting of the load, you may see reverse polarity of the cell with respect to original condition.

hope the result is not blowing up my refridgerator ,i cant do it my mom said "no" and dad said "you want to blow the fridge up?" :p

@sooraj the video has been uploaded ,sorry for the recording ,had to do it using my phone

No I don't think it will simply blast by freezing inside the fridge,
PS: I put it inside my fridge with out mom noticing, If she saw she may throw it out!!

LET ME TRY i DON'T THINK STREAMING WILL BE KNIFE ON BUTTER WITH A 2G CONNECTION !!

Oh my luck, It is only a 15min wait , to download on 480P

why not watch it ,its just 1.5min or download in 240p saves time

Hey wht is it's content?

setting up the hk board ...if you dont get it search "hk multi rotor fc board v3 flight test" ,there will be 2 videos check out the 2nd one,it is the setup

did it work??

Nope,
Tried many ways, now transmitter battery down.
BTW , where did you get this flight control board.?

got it from sundaram sir ,got it in the clearance sale
which FC are you using??

HK multirotor control board V3 , the one with atmega168PA microconroller.

@ sooraj and rohan123
the discussion is deviating from actual topic

@sooraj the one with the 168PA MCU is v2 .check online
@akhil sorry ,didnt want to start a new topic for a small discussion,and i am now soldering the wires and will keep you updated about the progress
regards
rohan

yup, Rohan, I will contact you via, phone.

However, I just left the hobbyking board setting up multiwii flightcontroller on the breadboard right now.

Mission accomplished ,the 3s 2200mah lipo is now a 2s 2200mah ,will discharge it and will charge it again to see if it works fine ,current voltage~8.47v ,thanx to sooraj and akhil
@sooraj i thought you had an exam :p ,ok call me whenever you want my no. is 9953971698(rohan sakhuja)
@akhil thanx for the advise ,and after i am done with this lipo i will send it to you positively. and if you want any electronic stuff ,a seller in chandni chowk is my friend so he gives me discount on electronics ,i can get it for you ,just pm me
regards
rohan  

have a question. can the 2s 2200mah battery be able to lift my quad upto 1-2 meters ,want to do some testing .
and for to be safe in the future at what voltage should each cell be discharged(3.7v or 3.3v)?
