Connecting 7.4V 10aH power supply to arduino nano without damaging arduino

Hi,

I have a project which has a power supply of 7.4V 10aH. I want to use this power supply to power an arduino nano board, yet I am unsure if the arduino board can take that much power without getting damaged.

What solution is there if this is a problem....

Thanks

If the device operates from 7.4volts then it matters not how many Ah the pack is. A device only consumes the current it requires, providing it is being powered by the correct supply voltage.

Thank you for your answer jackrae. What do you mean powered by the correct supply voltage? Would 7.4 volts be correct supply voltage?

Just connect the +7.4 volts to the Vin of the arduino nano - it's internal regulator will do the rest.
