Light & Motion 11.1V 6-Cell Li-ion Battery
The Light & Motion 11.1V 6-Cell Li-ion Battery is generally much lighter than other types of rechargeable batteries of the same size. This 11.1V 6-Cell Lithium-ion battery can handle hundreds of charge/discharge cycles. A lithium-ion battery pack loses only about 5% of its charge per month, compared to a 20% loss per month for NiMH batteries. In addition, it is compatible with Seca and Stella model headlights. It comes with a Velcro battery strap. Expect roughly 500 charge cycles from your Light & Motion 11.1V 6-Cell Li-ion Battery, and use Light & Motion's Smart Charger to re-juice.
