Four-Battery Kit with Wall Changer

This Kastar NP-FM50 kit supplies four lithium-ion batteries and a folding-plug AC charger. Each cell delivers 7.4 V and 2300 mAh for 17 Wh capacity. The set targets owners of compatible Sony Handycam, Cyber-shot and DCR models who need extended shooting time without carrying a bulky power bank.

Check Battery Model Before Buying

Verify that your camera or camcorder accepts NP-FM30, NP-FM50, NP-FM55H, NP-QM50, NP-QM51, NP-FM70, NP-FM71, NP-QM71, NP-QM71D, NP-FM90, NP-FM91, NP-QM91 or NP-QM91D cells. The charger only works with Sony BC-VM50, BC-VM10 or BC-V615 chargers, so confirm your original charger part number matches one of those three.

Replaces Single OEM Packs and Slow Chargers

Swapping a lone original battery for this four-pack multiplies available runtime for long events or travel. The included wall unit charges at 8.4 V 600 mA with red and green LED status, removing the need for in-camera charging or a separate USB power source.

Questions about this item

Does the kit include everything needed to charge all four batteries or must a separate power cable be purchased?

The AC wall charger has a foldable flat plug that connects directly to a mains socket, so no extra cable is required to charge the four included batteries.

Should I choose the 2300mAh NP-FM50 pack or a higher-capacity NP-FM70 or NP-FM90 version for longer recording time?

The NP-FM50 cells deliver 2300mAh at 7.4V; the NP-FM70 and NP-FM90 series offer larger capacities, so select the higher model only if your camcorder accepts those larger packs.

What does the 17Wh rating mean for actual shooting time in a Sony DCR-TRV30?

At 17Wh each, the four batteries provide roughly the same run-time as the original Sony NP-FM50, giving several hours of typical recording on the DCR-TRV30 before a recharge is needed.
