Replacement battery and dual charger

The Kastar NP-FV50 pack supplies a 1550 mAh lithium-ion battery together with an LTD2 charger that can replenish two cells at once. It targets owners of Sony Handycam and FDR models who need a spare power source and a compact way to top up both batteries between shoots.

Charging behaviour under sustained use

The charger accepts 5 V at 2 to 3 A through either Micro-USB or USB-C and delivers 8.4 V at 800 mA per slot whether one or two batteries are inserted. An LCD panel shows real-time capacity so you can monitor progress during extended sessions without guessing remaining charge.

Compatibility checks before ordering

Verify that your camcorder uses the NP-FV50 form factor; the list covers many FDR-AX and HDR-CX models but not every Sony camera. Ensure you have a 5 V USB power source rated for at least 15 W to run the charger at full speed. The package includes only a Micro-USB cable, so a USB-C cable must be supplied separately if that port is preferred.

Questions about this item

How much heat does the LTD2 charger produce when charging two NP-FV50 batteries continuously?

The charger outputs 8.4 V at 800 mA per slot, so total power is modest and heat remains low during extended dual-battery charging.

Which USB power source must I already own to run the LTD2 charger at its 15 W maximum input?

Any 5 V USB supply rated 2 A to 3 A — such as a standard phone charger or power bank with Micro-USB or USB-C output — will drive the charger at full speed.

Will the NP-FV50 battery work in my older Sony HDR-CX110 camcorder alongside the original NP-FV70 pack?

Yes, the NP-FV50 is listed as compatible with the HDR-CX110 and can be used interchangeably with NP-FV70, NP-FV70A or NP-FV100 batteries in that model.
