Black Diamond BD LT Battery

The Black Diamond BD LT Battery is a rechargeable, interchangeable lithium-ion battery pack made for Black Diamond's Distance LT 1100 headlamp. Carry a spare and the lamp keeps going long after the first pack runs flat.

It suits trail and ultra runners who run the Distance LT 1100 through long nights and early alpine starts. Swap it in when the first pack fades, then charge the spent one by USB. Black Diamond builds it with a polycarbonate and brass body, and its lighting gear is covered by a three-year warranty.

It is designed for the Distance LT 1100 only, so check your headlamp before buying. Planning a big night out? Charge both packs before you leave and you will rarely need to think about the lamp again.
