Voltage Regulator Motor Bike Burned Up My Voltage Regulator On My Bike?

Burned up my Voltage Regulator on my bike? - voltage regulator motor bike

I bought a new battery and installed when I snapped the lever a large cloud of smoke from the front of the bike. I contacted the battery in the same way as the old man did. The battery was at the age of just under a year. It drained my battery? This is a custom built bicycle with a motor of 113 Ultima. The bike is less than one year. Help please, thank you
