Two NP-FM50 batteries and dual USB charger

This pack supplies two lithium-ion NP-FM50 batteries rated at 7.4 V and 2300 mAh each, plus an LTD2 charger that powers both cells simultaneously. It is aimed at owners of compatible Sony camcorders and digital cameras who need spare power for long shoots.

Charger accepts Micro-USB or USB-C input

The LTD2 unit draws 5 V at 2 to 3 A through either port and delivers 8.4 V at 800 mA per slot, showing individual charge status on its LCD screen. A Micro-USB cable is included, so the charger can run from common power banks or wall adapters without proprietary cables.

Sustained output at 800 mA per channel

Under continuous charging the unit maintains the rated current to each battery until the LCD indicates full capacity, avoiding the taper-off seen in single-port designs. It is not suited for users who require faster than 800 mA per cell or who need to charge more than two batteries at once.

Questions about this item

How long can the two 2300mAh batteries run a camcorder before the 17.02 Wh capacity is exhausted?

Each battery stores 17.02 Wh at 7.4 V, so two packs give roughly 34 Wh total; actual run time depends on the camera's power draw.

Does the LTD2 charger become loud or hot when both slots are used for a full day?

The charger draws 5 V at 2-3 A (15 W) and outputs 8.4 V at 800 mA per slot, so heat and noise stay low during extended dual-battery charging.

Which cables or power adapters must I already own to use the Micro-USB and Type-C inputs?

A Micro-USB cable is included; you only need any 5 V 2-3 A USB power source such as a phone charger or power bank for either port.
