Capital gains on property sale

we had sold a property last f.y and had ltcg of rs.48,00,000 which we invested in rec bonds. 

this f.y we are selling another property and getting ltcg of approx 45,00,000. 

my query - is there any limit on an individual to avail capital gain bonds ? as per my understanding i can use the limit of 50 lakhs every f.y . please clarify.

thank you.
