The Westcott NP-F970 Dual Battery Pack with Charger bundle provides power to LED light fixtures when AC power isn’t an option. This bundle includes two L-Series 7.4V 6600mAh 48.8Wh Lithium-ion batteries and a dual battery charger. This battery bundle is an ideal portable power source for Westcott’s L60-B COB LED and any other fixture that accepts NP-F batteries. Run time is up to 2 hours with Westcott’s L60-B COB LED light using fully charged batteries at 100% brightness. At 50% brightness, the runtime increases up to 4.5 hours. The dual charger uses a USB connection for power, eliminating the need to carry a heavy AC power supply with you. Simply plug the charger into a standard USB charger or a USB power bank (all require 2.1A minimum voltage, sold separately), making this bundle a truly portable power solution for your lighting. | Westcott NP-F970 Dual Battery Pack with Charger(2-pack L-Series 7.4V 6600mAh 48.8Wh) in Black
