Four Li-Ion batteries and dual USB charger

This kit supplies four NP-FM50 lithium-ion batteries rated at 2300 mAh and 7.4 V, together with an LTD2 charger that powers two cells simultaneously. It targets owners of compatible Sony Handycam and Cyber-shot models who need reliable spare power for long shoots or travel.

Sustained shooting with hot-swap reserves

Each cell stores 17.02 Wh, so the quartet provides roughly four times the runtime of a single original pack. The charger delivers 8.4 V at 800 mA per slot whether one or two batteries are inserted, keeping charge current steady during extended sessions without thermal throttling.

USB-A micro and Type-C input flexibility

The charger accepts 5 V at 2 to 3 A from either a Micro-USB or USB-C source, so it works with common power banks, wall adapters or laptop ports. No proprietary AC brick is required, but the 15 W input ceiling means full dual-slot recharge takes longer than dedicated mains chargers.

Questions about this item

Does the LTD2 charger generate noticeable heat or noise when charging two NP-FM50 batteries continuously?

The charger runs from a 5 V 2–3 A USB source and delivers 8.4 V at 800 mA per slot, so heat and noise stay low during extended dual-battery sessions.

Which USB power source must I already have to run the LTD2 charger?

Any 5 V 2–3 A USB supply with a Micro-USB or USB-C port will power the charger; a Micro-USB cable is included.

Will the NP-FM50 packs work in my older Sony DCR-TRV10 camcorder and BC-VM50 charger?

Yes, the batteries replace Sony NP-FM50 and the kit is listed as compatible with the DCR-TRV10 and BC-VM50 models.
