Replacement Circuit Board for MaxxFan 5100k RV Roof Vent Compatible with Lithium Batteries


I have a MAXAIR 5100K and I need a replacement circuit board. I have lithium batteries and they can produce almost 15V. The old circuit board could not accept the high voltage. I do understand the Version 3.9 of this circuit board can take the higher voltages. Do you have the replacement circuit board version 3.9?


Expert Reply:

The MaxxFan circuit board part # MA10A21276K is what you are looking for. This is the current version of the board that is compatible with lithium batteries that have higher voltage.
