Narrative:
On approach to an offshore oil platform; I noticed smoke coming from the battery compartment in the nose of the aircraft. I proceeded to shut down after landing. Upon further inspection; I found that melting plastic was causing the smoke and removed it. I then continued my flight to our base onshore to have a mechanic inspect and fix the problem. Upon inspection an aircraft technician removed and replaced the battery relay. After review of far 91.7b and 135.65b; I realized my actions may have not been in accordance with these regulations.
