Now, I know that this is my first post, but I know a little about electricity. First what you have to think of is the maximum voltage that an LED can take, which is (usually) 3 volts.

If you choose parallel, all of the LEDs recieve the same voltage, which is the maximum a baterry can put out. So, if you use a 9 volt battery, unless you want to fry your LED's, don't use parallel. Instead, use 3 volts in parallel.

If you choose series, each LED will get an equal amount of voltage. If you want to use 3 LEDs, you will need 9 volts.


So, all of it depends on what you want to do. post, but I know a little about electricity. If you want to use a lot of LED's, the best option is to go in parallel.
