I'm looking to power a wireless security camera from a 12v 1.4a battery being charged by a 12v solar panel. question is will i over amp camera from solar panel? camera has rating of 12v .5a" don't know output of solar panel yet"
The solar panel will charge the battery, and the camera will draw power from the battery.
The camera will draw what it needs when in use. So since it's a 1.4A battery, the camera is only going to use 0.5A of the available current and keep the rest to charge the battery when the solar panel is active.
