Two-pack replacement batteries

This Kastar two-pack supplies NP-FV50 lithium-ion cells rated at 7.2 V and 1 550 mAh each, delivering 11.16 Wh per unit. They are built as direct replacements for Sony NP-FV30, NP-FV50, NP-FV70 and NP-FV100 batteries and fit the long list of Handycam, NEX-VG and FDR-AX models shown in the compatibility data.

Thermal and power behaviour

Lithium-ion chemistry keeps self-discharge low and the integrated protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating during normal recording sessions. The cells meet UL1642 and CE safety standards, so they operate within expected temperature limits for camcorder use without requiring extra cooling.

Sustained recording performance

The 1 550 mAh capacity supports extended shooting compared with lower-capacity NP-FV30 packs, and the protection circuitry maintains stable output throughout a full discharge cycle. Users who need continuous power for multi-hour events should note that a single battery may not cover the entire session without a swap or external charger.

Questions about this item

How do I install the NP-FV50 battery in my Sony HDR-CX300 camcorder, and what step do people often miss?

Slide the battery into the compartment until the latch clicks, then charge fully on a Sony BC-TRV charger before first use; skipping that initial charge is the common mistake.

What maintenance will the NP-FV50 batteries need over time?

Store at about 50 % charge in a cool place, cycle both packs every few months, and clean the contacts with a dry cloth if the camera reports a communication error.

What limit appears first during continuous recording with the NP-FV50 on an HDR-CX550?

The 11.16 Wh capacity typically delivers one to two hours of HD recording before the pack needs recharging, so runtime is the first constraint.
