Four NP-F550/F570 batteries with dual USB charger

The pack contains four lithium-ion batteries rated at 7.4 V and 2900 mAh each, plus an LTD2 charger that powers two cells simultaneously. It is aimed at videographers and event shooters who need extended run-time for compatible Sony camcorders without carrying bulky mains adapters.

Replaces single OEM packs

Swapping to this kit is worthwhile when a shoot day exceeds the capacity of one original battery or when the supplied charger can only handle one cell at a time. The dual-slot design cuts total recharge time roughly in half, so crews spend less wall-clock time waiting between takes.

Limited to NP-F series footprints and 5 V USB input

The charger accepts only Micro-USB or USB-C at 5 V 2–3 A, so it cannot draw from higher-voltage PD bricks or proprietary camera docks. Batteries larger than the NP-F970 footprint will not fit the sliding plate, and the 800 mA per slot output means full charges take several hours.
