We read many posts online talking specifically about the MaxxFan's control board failing with voltages higher than 13.9 volts. Using Li batteries, solar controllers for Li charging, & Li capable converter charger, it's necessary to charge at voltages in the 14v range.
Has MaxxFan updated their boards for Li battery use in the 14v range?
Are any other devices/applicances in the 5.0 at risk when voltages are in the 14v range while using Li batteries & chargers? Did see mention that control boards on the water heater and furnace may also be sensitive to the14v range, like the MaxFan.
