Four-pack lithium-ion batteries

This set supplies four Kastar NP-FV50 lithium-ion cells rated at 7.2 V and 1550 mAh each. They replace Sony NP-FV30, NP-FV50, NP-FV70 and NP-FV100 batteries in a long list of Handycam and Action Cam models. The pack suits videographers who need several spares for all-day shoots.

Thermals and power in use

Lithium-ion chemistry keeps self-discharge low and delivers steady voltage through the discharge curve. Built-in protection guards against over-charge, over-discharge, over-voltage, over-current and over-heating during normal recording sessions. Each cell stores 11.16 Wh of energy.

Upgrade path and when to switch

The pack replaces ageing original cells that no longer hold a full charge or that swell with age. It also suits owners who currently carry only one battery and run out of power mid-event. Buyers needing higher-capacity cells such as NP-FV70 or NP-FV100 equivalents should look elsewhere.

Questions about this item

How do I install these NP-FV50 batteries in my Sony HDR-CX350 camcorder?

Slide each battery into the compartment until the latch clicks; the common mistake is not pushing far enough so the contacts do not seat properly.

What maintenance will these Li-Ion packs need over time?

Store at roughly half charge if unused for weeks, keep contacts clean, and replace a pack when run time drops noticeably below its original level.

What limit appears first during continuous recording with the HDR-CX350?

The 1550mAh capacity sets the runtime ceiling; expect the battery to deplete before thermal protection activates.
