Hi Sreedhar

The purpose of discharging is to cycle your batteries. By cycling i mean draining you battery and then charging it (1 cycle). This should be done every 2-3 months to increase the life of your batteries.Brand new lipos should be cycled approx 5 times before using them.

regards

when we normally charge the battery (lipo) will it be balancely charged???

That depends on your charger. If you are using a standard wall charger for charging it wont balance your lipo. Advanced charger in which you have to connect the balancing port (on the lipo) with the charger are capable of balance charging.

http://www.rcindia.org/batteries-and-chargers/site-with-lots-of-good-information-on-lipos/  should tell you all you need and more

Also see other "sticky" threads in the http://www.rcindia.org/batteries-and-chargers/ board.

Discharging a new battery rule not only applies to lipo but applies toallre-chargeable batteries..if you remember when ever you buy a new mobile themanufacture gives a note not to charge thebattery immediately after installation, but to discharge thebattery fully and recharge the same atleast 2-3 time...this is to be done to maximise the battery life....the same case is to be done for lipo batteries...since yesterday i have discharge all my batteries and recharged...believe me you will see some good performance differance after this process.
