Four-battery pack for Sony camcorders

This Kastar set supplies four lithium-ion cells rated at 7.4 volts and 2300 milliampere-hours each. They replace the NP-FM50 and NP-FM55H packs used in a wide range of Sony Handycam and Cyber-shot models. The bundle suits owners who need several spares for long shoots or multi-camera setups.

Built-in protection and broad charger support

Each cell carries over-charge, over-discharge, over-voltage, over-current and over-heating safeguards certified to UL1642 and CE standards. The batteries fit the original Sony BC-VM50, BC-VM10 and BC-V615 chargers, so existing charging gear works without change. The lithium-ion chemistry avoids memory effect and holds charge during storage.

17 watt-hour capacity per unit

Every battery delivers 17 Wh, which determines how long a compatible camcorder or camera can run between charges. Buyers who need higher energy per cell or a different voltage will have to choose another product.
