@rcrcnitesh
Surely you know that no 2s can power a Tx, being at best 8.4v.

@ Nitesh. RCB 6i can be set in the menu to use a 2S. i.e. 7.4 lipo and you can use a 2S lipo or you can set it to use a 4 cell Nimh. But it's not recomended to use a shorted 3S lipo which is giving 2S voltage.

@ Iyer sir this radio RCB 6i has a menu feature to select various battery and voltage types.

I read the RCB6i manual and you can use either a 4 cell rechargeable pack or lipo ! (does'nt your transmitter come with 4 cell NiMH pack?).

its not completely correct, i have a Sanwa SD-10G and it works on 2S so do many recent 2.4Ghz radios (please update yourself).

Oops. Deserved that.
Well, one lives and learns.
My Hitec is now on lipo, so the Nimh was free.
Used it with a RICCS Tx, but the green light never came on. Only red plus yellow.
Ie, 9.6v Nimh not enough for a system designed for 8x1.5v dry cells.
So only using it on wireless sim (courtesy Gusty!)

Nitesh,
Why didn't you just do a range check?

The voltage is not a problem. My battery is a 2cell battery originally and i shorted it by mistake but still the voltage is correct and its not puffed i planned to use it on my tx as the tx will consume less current and the battery will not be at load but if i use it in my plane the current will be high and the battery will be at load. I was thinking if I use it on my tx it will be safe as it will be under less load.. When I contacted rcb they told the c rating is high so it is not recommended the battery will spoil. What should I do now, should I  keep using it on my plane or use it on my tx.

Why do you say after it was shorted it has to be used for Tx only. Was the battery in short circuit condition for that long to spoil the battery? Do you feel depreciated performance on Motor ESC Usage? Is the Lipo drooping voltage too much before it can deliver the recommended 'C' rating amperage discharge or the capacity but recovers voltage after some time? 

1.3 AH at 25 C rating should give ideally 32 Amps Max. You should be able to use it at a safe 20-25 Amps load continuous application without drastic drop in voltage. This you can check only if you have a watt meter. But if its not delivering say not even 10 Amps and dropping voltage drastically every time you attempt, but it recovers voltage after some time, and you are never able to charge the battery to the rated capacity say not even to its 50% capacity and the battery shows charged full capacity within short duration, Then you have a battery which has been damaged and depreciated  "C" ratings.

Though radio is a device which consumes not more than 200-300 ma max depending on the Type/ model for its operation, usage of a higher 'C' rated Lipo will in no way will affect its operation or performance or spoil it in anyway. ( All recommended Lipo's for radio (5C ratings) even if at 1C rating is much higher than what is required for radio).

Having said that Radio is a very important component of RC flying and I would not recommend usage of a product which you know for sure has been damaged or has a fault line.

Sundaram Sir I have not checked all these things.

I am not sure whether the battery is damaged.

While I was checking the voltage of individual cells of the lipo using a multimeter I mistakenly shorted one of the cells but it was not in that condition for more that 0.2 seconds though the battery was not puffed and the voltage remained the same even after I shorted the battery.

A momentary short circuit is not a major deal. You can continue to use it for motor and ESC application and as well as Radio Application if you choose to.

I think of using it for radio and buy a new 1800mah indpower battery for my plane (this will solve the balance issue of my plane)
thanks everyone Hats Off
