Tao Tao 125D Voltage at battery

I recently purchased a tao tao 125D atv. After 30 minutes of riding I heard a loud pop from under the seat. I took off seat to find the battery acid cover had popped off and all acid had boiled away. I checked voltage at battery and read 16.5 volts when rpms were at riding level. This seemed way high to me so i though the voltage regulator was bad so i bought a new one and replaced, but still reading 16.5 Volts when rpms are up. After idling for about 2 minutes you could hear the battery boiling. What else could cause this high voltage at battery?
