I have one on my 04 Bullet and it works fine without a battery, however I changed all my lights to LEDs (excluding the headlight because that runs straight off the alternator). They draw such a low current that the amp meter barely moves when I turn the lights on, I'm no expert but this seemed logical to me. Also you don’t want your idle speed too low.
