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?
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.
