How to properly power LED Strip Lights using battery for mobile sign?
So, here is the plan, I have purchased a strip of LED lights (see them here: http://www.amazon.com/dp/B005EHHLD8/ref=pe_385040_30332190_TE_tr_3p_M3T1_ST1_dp_1) and am attempting to place them on a mobile sign. Imagine a person walking around on the street after dark with a sign that is nice and bright with LED strip lights.
Obviously, these need to be battery operated, and I have seen it done with something like a cell phone battery and charger type thing and would like to duplicate that. I do not know how much power the battery would need, or if resistors would be needed (or even how a resistor works). Can anyone provide more insight for me?
Thank you again!
