Attach your battery to your headband, helmet or bike frame with just one click.
Waterproof, rugged and safe
Each Lupine Li-Ion battery is absolutely waterproof and its extremely robust outer shell made of ABS plastic provides excellent protection against external forces. The integrated switch-off electronics reliably protects it against bad currents.
Optional SmartCore technology offers even more. Colored LEDs and an audible signal indicate how much power your battery has left at the touch of a button. The additional run and rear light function increases your visibility and safety if you don't have a rear light at hand.
Just one click
With just one click, you can attach your battery directly to your headband. The FastClick battery clips hold it securely in place even under heavy loads.
