If you have regular lead acid batteries you should be fine.

Might be good to check with MaxxAir on this...I seem to remember that they updated the circuitry to correct this issue.

I just talked with Perry from Airxcel support. Airxcel are the makers of the MAXXFAN and he told me that the voltage issue was solved several years ago and that the new control boards now handle from 10.3 vdc to 15 vdc.

I will add that I have been VERY impressed with Airxcel support.
