Default Maximum Voltage of Tripath TPA2020 (Lepai)

Hi guys.

Did anynoe testet how much input a Lepai Tripath amp will take?
a Pb Bat can go up to 14.7V when full, so that should be ok
But i want to use LiIon.
3S will be not used completely, cause the Lepai shuts off at 9.5V
4S will go over 16V when fully charged

Can the Lepai take that or be adjusted/modded to not be killed?

If you want to be safe, use a DC-DC step-down converter (Try Analog, linear, and mixed-signal devices from Maxim/Dallas Semiconductor for info)
