I am trying to drive a 1w diode with a 14500 battery, but the voltage cannot keep up and when it drops below 3v the driver shuts off.
Here is an image of the voltage over time on an ocillascope. If I add a cap to this will the laser stay on for longer, or is it just a matter of the battery not being able to supply the current needed?
I would like to use the smallest cap possible so it fits in my build, but it seems that they come in sizes up to 5F (holy shit!) for the voltage range that I am using.
Here's the graph (sorry I forgot to post it at first)
