Four-battery kit with dual-slot USB charger

This set supplies four lithium-ion NP-FM50 cells plus an LTD2 charger that powers two batteries at once. It targets owners of compatible Sony Handycam and Cyber-shot models who need spare power for long shoots or travel. The pack replaces original NP-FM30, NP-FM50, NP-FM55H, NP-QM50, NP-QM51 and higher-capacity NP-FM70-series cells.

17.02 Wh capacity per cell

Each battery stores 17.02 Wh at 7.4 V (2300 mAh), matching the energy rating of the original NP-FM50. The charger accepts 5 V 2-3 A input via Micro-USB or USB-C and delivers 8.4 V at 800 mA per slot, so a depleted pair reaches full charge in roughly the same cycle as the stock BC-VM50 unit.

Handles a full day of DV recording.

Four cells give enough headroom for a typical day of standard-definition camcorder use or several hundred stills on a DSC-F707. Users planning overnight events or multi-day trips without mains access will need additional packs or a power bank to keep the charger fed.
