Four-Pack Li-Ion Replacement

This four-pack of Kastar NP-FV50 lithium-ion batteries replaces the Sony NP-FV50 and compatible NP-FV30, NP-FV70 and NP-FV100 cells. Each unit delivers 1550 mAh at 7.2 V for a total energy rating of 11.16 Wh, giving camcorder owners multiple spares for extended shoots.

Upgrade from Single OEM Cells

The bundle suits users who currently rely on one original battery and need longer total runtime without frequent recharging. It is not intended for cameras that require higher-voltage packs or proprietary communication protocols beyond the standard NP-FV interface.

Simple Battery Swap

Installation is a direct slide-in replacement for the original pack in supported Handycam and Action Cam models; the built-in protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating. No firmware update or charger modification is needed, but the pack will not work with devices that authenticate batteries through encrypted handshake.

Questions about this item

Will the 3*2*3 Inch NP-FV50 pack fit the battery compartment on my Sony HDR-CX115?

Yes, the NP-FV50 form factor matches the original Sony NP-FV50 so it slots directly into the HDR-CX115 battery bay without adapters

What is the correct way to install the four batteries and what step do users often miss?

Insert each 7.2 V pack with the contacts facing the camcorder terminals until it clicks; the step often missed is fully charging all four units on a Sony BC-TRV or BC-VH1 charger before first use

When should I replace the 1550mAh Li-Ion cells in this four-pack?

Replace a cell when it no longer holds enough charge for a full recording session or shows swelling, which can occur after extended use and many recharge cycles
