As the balloon rises up, it displaces the air of the atmosphere. the potential energy of the atmosphere hence decreases. the total energy of the balloon-atm system is conserverd

Kinetic energy is the sum of the work done by the external forces...

So Kinetic + Po\tential should have been zero..

There is work done by bouyancy.. That is something you have to also consider.. :)
