Question:

I have a Maxxfan Deluxe model 7000k. When I replaced my batteries with lithium ion the maxxfan stopped working properly. It comes on momentarily then shuts off leaving a solid green light. I am guessing it doesnt like the slightly higher voltage. If I order another mother board from you, will it work with the lithium setup. I think the replacement board is MA10A21275K. Is that made to withstand the higher voltage? Please let me know what you think.

Expert Reply:

Yes, it will! We've encountered this problem before. The old motherboards do not like the higher voltage output from Lithium batteries.

Thanks for the picture! Since you have the MaxxFan Deluxe 00-07000K you will need the Replacement Printed Circuit Board item # MA10A21275K. This is built to work with the higher voltage.
