Four-Pack Li-Ion Camera Batteries

This set contains four Kastar lithium-ion batteries rated at 7.4 V and 2300 mAh each, supplying 17 Wh per cell. They are built as direct replacements for Sony NP-FM50 and NP-FM55H packs and include over-charge, over-discharge, over-voltage, over-current and over-heating protection circuits. The cells meet UL1642 and CE safety standards.

Suits owners of compatible Sony Handycam

The batteries fit a long list of Sony camcorders including the DCR-TRV and DCR-DVD series, the DCR-HC and DCR-PC lines, and Cyber-shot models such as the DSC-F707, DSC-F717 and DSC-R1. They also work with Sony BC-VM50, BC-VM10 and BC-V615 chargers. Users of cameras that require a different battery form factor or voltage should look elsewhere.

Capacity and headroom

Each 2300 mAh cell delivers 17 Wh, giving extended recording time compared with lower-capacity original packs. The four-pack provides enough reserve power for multi-hour shoots or all-day events without swapping cells. Runtime will fall short for very high-draw accessories or extended sessions that exceed the combined capacity of all four batteries.

Questions about this item

Will these NP-FM50/NP-FM55H batteries charge in my Sony BC-VM50 charger?

Yes, the pack is listed as compatible with Sony BC-VM50, BC-VM10 and BC-V615 chargers.

Can I mix one of these 2300mAh cells with an older NP-FM30 battery in the same camcorder?

The batteries share the 7.4V voltage, but different capacities will discharge unevenly, so using matched pairs is recommended.

How can I verify the built-in protection circuit is active after the first charge?

The battery should power the camcorder normally and stop charging automatically when full; any abnormal heat or swelling indicates a fault.
