Watch out, the voltage out of that battery charger is the unregulated battery voltage.

  Thanks, this felt fine though. I added a small resistor to limit the current, but even without it (direct battery) the light worked fine. I didn't think I'd need a boost converter here.

    It has low voltage cutoff on the battery so you're probably fine.

      Thanks! I just added the (very basic) circuit schema.
