From where i can get this type of lipo and charger for the lipo ..
it is 3.7v 1300mah (18500--dont know what this number means.)
came with the 3.5 channel volitation helicopter.

I guess this is a non-standard one... In that case you have to use the one provided by the seller or hack an existing charger to do the job for you.
