But now this Rhino i never used it Sad was planned to use but never got a chance to. Today was checking my box for all the stuffs and found that my rhino battery is puffed  Cry dont know how it happend. Never used it never charged it. But how can this happen?? What should i do?

Also few other things that i want to knw, today i charged my 4000mah lipo for the first time.

I charged it at 1.6A is this right amps to charge this?  Head Scratching
Now it reached 12.6 v but it still was charging i thought i would stop at 12.6 i dont have to do nething.. Is this normal dat we have to stop charging after it reaches 12.6v?  Huh?

Satya, its happenned because of deep discharge of the cells.. when deep discharged, because of the nature of polymer salts battery become swelled.. and while using a programmable charger, we must take extra care to programme the charger in to the specific values of the batteries.. if not a wrong charge current may damage the cells.. this is why i always preset chargers.. this will take a little extra time but never hurts battery.. one of the proved charger is I Max B3.. was suing about 2 years regularly, and still works fine.. please take extra care while handling the swelled cells..

i think 4.20V per cell is max value. your charger should stop charging at 12.6.

@satyagupta and @mohit, dispose the batt. Not worth the risk. Next time, charge ur lipo with the 'storage charge' option if u dont plan to use it fr sometime. Also, it is advisable to charge and discharge the batt @least once a month. Preventive maintenance! Cheers.

Dear all,
With Lipo battery is never adviced to take risk, as mentioned above In a fellow modeller post that one should be very care while setting up you charger with correct no of cells, charge current and the capacity of the battery. Whenever you notice that your Lipo battery has been puffed up, it's highly adviced to dispose it and get yourself a new pack. Today most advance chargers comes with storage program, this means if you don't want to use your battery for long then just input the correct data of your battery in your charger and press start, then charger in return charges or discharges the battery to 60%, that is the approx voltage that a Lipo battery can be stored.
