how can i measure how many cicles (ie. 15 second cicles) a given dc motor can run on a battery? votage, current ? =O
+ the battery is 12v, 1.3Ah, Li-ion
+ the dc motor is still unknown, but i think we can use variables in the place of the data
+ the solar cell gives in 0.3Ah
What i plan to do is: the motor will run intermitently, being actioned by a switch. When actioned, it will run for 15 seconds and stop until the switch is pressed again. I need to know how many times the motor cand do this cicle until i have to charge the battery again and; how much time will it take to charge the whole battery with the maximum output (0.3Ah) from the solar cell.
