Four-Battery Pack with Dual USB Charger

This set delivers four NP-F550/F570 lithium-ion batteries and an LTD2 charger that powers two cells simultaneously. Each battery stores 2900 mAh at 7.4 V for 21 Wh of capacity. The charger accepts Micro-USB or USB-C input at 5 V 2-3 A and outputs 8.4 V at 800 mA per slot. An LCD panel shows charge status and remaining capacity for each battery.

Replaces Proprietary Sony InfoLITHIUM Packs

The batteries substitute for Sony NP-F330, NP-F550, NP-F570, NP-F730, NP-F750, NP-F770, NP-F950, NP-F960 and NP-F970 packs used in Handycam, Cyber-shot and DCR camcorders. Swapping to this kit is worthwhile when original cells no longer hold a full day’s charge or when a shoot demands more spares than a single OEM battery provides. The dual-slot charger cuts total recharge time compared with single-bay units.

USB Power Input Limits Field Use

Charging relies on any 5 V USB source delivering at least 2 A, so a standard power bank or wall adapter works. The 15 W input ceiling means both slots share 800 mA each; charging four batteries requires two cycles. No AC cable is included, and the charger cannot operate from 12 V vehicle sockets without a separate USB adapter. The fixed NP-F plate prevents charging other battery form factors.
