Will my chain of LED strips burn out?
Question: If I were to chain four or five of these strips together, would they be able to handle the amount of current drawn at 12 V? If not, would connecting wires to ground at each chain prevent too much current being drawn?


The issue will be the voltage drop along each strip. Too many strips and the next strip will be dimmer till it makes no sense any more. Powering from both ends will help, but if need be you will need to run extra wires to both the ground and the power side at some intermediate point.

BTW: You can calculate the power lost to wire heating in each segment by the following formula.

\$(I_{out} + (I_{in} - I_{out})/2) * V_{Drop}\$
