4-Pack 21 Wh NP-F Batteries & Dual USB Charger

This set includes four lithium-ion NP-F550/F570 batteries rated at 21 Wh each and a dual-slot LTD2 charger. The charger accepts both Micro-USB and USB-C input at 5 V 2–3 A and can charge two batteries simultaneously. Intelligent LED indicators show charging status and remaining capacity for each cell.

Suits video shooters needing extended run-time

Videographers using GVM LED panels or Sony Handycam models listed in the compatibility data gain a portable power bundle with hot-swap convenience. The kit is less suited for users who require higher-capacity NP-F970 cells or a charger that supports four simultaneous bays. Buyers locked into proprietary battery formats outside the NP-F family should look elsewhere.

Dual-input charger with swappable plates

The LTD2 charger ships with a Micro-USB cable and offers both Micro-USB and Type-C ports, letting you power it from common power banks or wall adapters. Interchangeable plates allow the same unit to charge other NP-F series batteries beyond the included four. Real-time LED read-outs remove guesswork by displaying individual battery capacity during charging.
