Two-pack NP-FW50 for Sony mirrorless

This twin pack of Kastar NP-FW50 lithium-ion cells replaces the Sony original for Alpha 7 series, Alpha 6000 series, NEX and Cyber-shot RX10 cameras. Each unit delivers 7.2 V and 1650 mAh for 11.8 Wh of capacity. Photographers carrying a spare gain extended shooting sessions without hunting for a wall outlet.

Compact cells with multi-protection circuitry

The batteries measure three by two by two inches and slide into the same compartment as the OEM pack. Built-in safeguards guard against over-charge, over-discharge, over-voltage, over-current and over-heating. They charge on Sony BC-VW1 or BC-TRW chargers and also power the VG-C1EM and VG-C2EM vertical grips.

Steady output with no active cooling

Lithium-ion chemistry maintains consistent voltage through the discharge curve, so the camera meter stays accurate until the low-battery warning. No fan or moving parts means silent operation during video recording. The protection circuit limits current spikes, reducing stress on both the cells and the camera power rail.

Questions about this item

What voltage does the 7.2V NP-FW50 deliver to the camera?

Each cell supplies a nominal 7.2V, matching the original Sony NP-FW50 specification for all listed Alpha and Cyber-shot bodies.

Will the 3*2*2 inch pack fit inside the Sony VG-C2EM grip?

The 3 by 2 by 2 inch form factor matches the OEM NP-FW50, so it seats correctly in the VG-C2EM and VG-C1EM grips.

How do I install the pair, and what step is often missed?

Insert each battery until the latch clicks, then charge both in a BC-VW1 or BC-TRW charger before first use; skipping the full initial charge is the common error.
