Would Arduino Pro Mini fry if i m using 8 brand new batteries of "D" direct into the RAW pin? The multi-meter is showing as 12.97 volts. Because I have looked up Arduino Pro Mini document see here. Please me know if is good practice or not.
Also, I have up look up battery capacity the each "D" has 13000. Would be okay if i am using 8 battery times 13000 so I am getting 104,000 mAh as long its standard voltages?
