Vineet, didn't understand the problem

pankaj sir modified the post , plz guide if it needs more description.

Hi Vineet,
you can only put a 6 cell battery directly to the charger connector. if you want to use 2 - 5 cell battery you have to use the board provided with the charger. To charge 1800 mah battery current should be 1.8 amp or 2 amp max.

Charging your battery at 1C (i.e. 1800mA) will take 1 hour to complete charging from a dead battery.

If your battery supports 2C charging (most of the turnigy and Zippos do, check on the battery pack) then you can charge it upto 3.6amps. (3600mA) and it should get charged in 30 mins from a dead battery.
Nanotechs support upto 5C charging which means they can be charged at 5 x 1.8 amps and they can be fully charged in 12-15 mins (60/5). from a flat pack.

However, It is advised to charge Lipos at 1C for longer life.

yes sir you are right as the female connector doesnot allows any male connector except 6 cell,   what i was told that hold the balancing pins in the right hand as the blocking bridges should appear up ,and then put them into the female connector of the charger starting from minus sign to plus sign on the charger (signs are mention on the both end of female connector of the charger )   

before that we need to cut the one bridge from given two bridges on the balancing connector .

what do you say ??

thanks.

hi
saurabh

i was doing the same thanks for the conversation ,

so why my battery  got burge , only one cell , only for once  i  accidently put the battery on 5a fast charging to tickle it as the charger was showing low battery ,may be because of this , and it is even heating on discharging when i am running motor on full throttle .

Bad news. You  have a ruined cell in your pack!

try and reach the field on Sunday with the battery, lets see your setup and then decide the next course of action
