Three-battery pack for Sony Handycam and Cyber-shot

This Kastar three-pack supplies lithium-ion cells rated at 7.4 volts and 2300 milliampere-hours each. The batteries replace the Sony NP-FM50 and NP-FM55H types used in a long list of Handycam and Cyber-shot models. Condition is new.

Built-in protection circuits

Every cell includes over-charge, over-discharge, over-voltage, over-current and over-heating safeguards that meet UL1642 and CE standards. The packs work with Sony BC-VM50, BC-VM10 and BC-V615 chargers, so existing charging gear can be reused without change.

Suits owners of multiple compatible camcorders

Videographers who run several supported Handycam or Cyber-shot bodies gain three matched spares in one purchase. Buyers who need a different voltage, a higher capacity, or a single battery for a non-listed model should look elsewhere.

Questions about this item

How many charge cycles will the 2300mAh Li-Ion cells last before I need new batteries?

The supplier states the built-in protection circuit improves cycle life, but does not publish a specific cycle count for these 17 Wh packs.

What is the first limit I will hit during a long recording session with the 7.4V packs?

The 2300mAh capacity (17 Wh) sets the total run time; once depleted the camera stops until recharged.

Do the NP-FM50 / NP-FM55H replacements run hot or draw extra power when the camcorder runs all day?

Built-in over-heating and over-current protection circuits keep temperature and power draw within safe limits during continuous use.
