If you want to destroy your LED you can do that
However, your "generator" is no longer of much use. A generator generates alternating voltage / current. An LED is operated with direct voltage! You have to rectify and smooth the current from the "generator" first. See bridge rectifiers here in the ELKO. After you have rectified the voltage, you can connect it in series, but only after the rectifier circuit, but do not think it makes much sense, the only thing you can achieve is a voltage increase. What is the point of the "generator" if you clamp a battery in front of it ?!
