Dual NP-F970 battery kit for portable LED lighting

This bundle supplies two 7.4V 6600mAh 48.8Wh lithium-ion batteries and a dual charger. It targets photographers and videographers who need reliable off-grid power for fixtures that accept NP-F cells. The kit is built around Westcott L-Series chemistry and suits location work where mains power is unavailable. It is not for users who require V-mount or Gold-mount battery plates.

USB charger with 2.1A minimum input requirement

The dual charger draws power from any standard USB source rated at 2.1A minimum, removing the need for a separate AC adapter. Simply connect the charger to a compatible USB charger or power bank sold separately. The main installation pitfall is using an under-powered USB port, which will prevent the batteries from charging correctly. No additional cables or mounting hardware are included in the box.

6600mAh capacity delivering up to 4.5 hours

Each battery provides 48.8Wh, giving a pair up to 2 hours of runtime on a Westcott L60-B COB LED at 100% output. At 50% brightness the same setup reaches 4.5 hours, offering practical headroom for interview or event shoots. Runtime drops proportionally on higher-draw fixtures, and the kit cannot power lights that demand voltages outside the 7.4V NP-F standard.
