Hi modellers. One of my Transmitter battery cell, has gone Zero while using. 2nd cell from my 3S lipo is showing 0.00 :o
This is my Lipo http://www.hobbyking.com/hobbyking/store/__9787__Turnigy_1450mAh_3S_11_1v_Transmitter_Lipoly_Pack.html
My Charger http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=102_96&products_id=156
Please help me to charge it. or let me know is there any other solution to it. :help: :help: :help:

I have same battery and ran into same situation, however not zero but around 1.1 volts so charger was unable to detect it. Just put it sometime and try again. It worked for me. Other method is to charge by ni-mh charger, somewhere posted on forum by a user but i forgot it.
I have the same problem too! I got a 1.3Ah 3S LiPo (I guess it's meant to be used on Txs) as a gift when I purchased a bigger battery.
All the 3 cells of the battery are visible to the outside seperately, and the outermost cell, which has apparently suffered a minor physicial damage gives me nothing more than 0.3V. So my 3S is a 2S now, even after charging. Someone please help! ???
There are already very informative threads on "reviving" over-discharged lipos.

Thanks Anwar sir, Read all those related , but now , what can i do to live that cell ? ???
Some one suggested to use different charger (nimh)
Please any other option to live it again. Can i try to charge it again with same charger for more than a hour . Because some one suggested not to charge such cell, it may catch fire.
Please SENIOR members help :help:
Did you understand what "trickle charging" means from reading those responses ? If you did, then you should be all set for *trying* it out. Remember that there is no guarantee for this, and some lipos can be revived, others are lost forever.
Anwar sir , i understand "trickle charging". but the charger i have doesnot have any settings to bring charging rate at 0.1A
Should i buy a new charger ? Please suggest a good charger with light load on the wallet.
Did you check the output voltage on the cell using a multimeter?
I checked it with digital lipo checker http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=102_94&products_id=463&zenid=jij92ea2bi1hd2nr5oke57co45.
it shows 0.00
I do not know how that device works but i suggest you test using a multi meter.

This link will show you which pins to check

That device is perfect in detecting lipo voltage . I am using it from long time, ans it shows correct volts on my other battery.
Yes but how accurate is it when the lipo discharges below its normal threshold? In any case it you really think the cell is giving out "0" volts then there's not much that can be done. And for trickle charging you can use an ni-cd/ni-mh charger.
Thanks a lot. I will try with ni-cd/ ni-mh charger. We see if i get one .
For trickle charging, the lower you go on charge current, the better. Hopefully what you are trying is around 0.2A.
The cell did not got charged. At last I carefully remove that cell and converted the lipo in 2s.
Friend as stated on this tx lipo it is low discharge with Discharge(c) = 1. Can i use the new modify 2S lipo with my brushless motors ?
Modelers waiting for your Valuable feed back . :)
8-) Waiting for replies.........
Typically TX lipos will be around 3C discharge rate, so they would not *usually* provide enough current to run brushless motors. You have to know your current consumption requirements to say with absolute certainty.
The short answer is NO.
Thanks for the reply Anwar sir :thumbsup:
it goes like this
(1450/1000)*3C (if 3c is the discharge rate) = 4.35 amps

Hope i have copied the link right. it is the last but one charger on page 2 on the hobbyking list of battery chargers.
It charges each individual cell separately through the balance plug. So it does not ram the whole charging current through the output leads. Very useful for TX lipos. no need to disconnect the battery. just charge in situ with the ballance plug.
i got one from Sai. Very low tech, but perfect for me. Works well. Again no guarantees, but if you want, i can try charging the battery for you. you have to pay return postage if you don't want to buy the charger.
hope this helps
