What charger? The lipo is possibly a lemon. The alarm beeping means you have low voltage. Could be just a dead cell or the whole thing is pooched.
IMO, don't put tape over a battery unless you want to insulate it to prevent it from dissipating heat. Battery will fail sooner and in the event you overheat a lipo....have fun
