12V 7.2Ah rechargeable battery to be used as external supply for arduino


Gab Cruz

Hi all. I have a project wherein I need to supply the arduino for a long time so I decided to use the 12V 7.2Ah battery (the bulky one). I am planning to plug it in the dc jack of the arduino. I've read that the maximum input of the arduino is 12V. Is it safe? Thank you very much.
