AC dyno light on battery pack? I'm running a Supernova E3 PRO 2 of my dynohub. However I would like to use my non-dynohub front-wheel whilst still being able to use the same lights on battery power.

The lights have an internal AC/DC converter, so I can't just go around that. Would is be possible to just hook up a couple of AA batteries or an USB-powerbank?

UPDATE

Turns out you do need a DC inverter. It works for a few minutes, after which the light turns off. After connecting it to the dynohub it was working again.
If the AC/DC convert is a simple rectifying bridge plus filter and voltage stabilizer, it should work with a direct current source as well. The only question is how many batteries connected serially you will need to reach the minimum acceptable voltage. Given that specifications for your lamp say to use 6 V A/C you can go with four AA batteries or two 18650 accumulators.
