Busch and Muller Ride and Charge specs
As background info to put everybody on the same page: The Ixon IQ is a bike light that runs on four AA batteries, and has an external port for a wall charger. The Busch and Muller Ride and Charge adapter/cable allows you to connect your dynamo hub to the charging port and thus run your lights, effectively charging your batteries on the go.
Is anybody here familiar with what kind of power comes out of the Busch and Muller Ride and Charge adapter? I'm not to leave well enough alone so I'm trying to figure out if I can charge a different four AA cell battery pack with it. Why? because the other battery pack would have a convenient USB slot proven to work with anything, including finicky Apple products. The battery pack also has a charge limiter, something not on the Ride and Charge nor the Ixon IQ light. If you don't disconnect the charger it can overcharge and burn your batteries on the light.
Also (again question on the Ride and Charge adapter), it has the box with electronics and a small bump on the cable itself going to the lights. what sort of electronics are on that bump?
