Three-battery kit for legacy Sony camcorders

The Kastar NP-FM50 pack supplies three lithium-ion cells rated at 7.4 V and 2 300 mAh each, plus a dual-slot USB charger. It targets owners of older Handycam and Cyber-shot models that accept NP-FM or NP-QM series batteries and who want spare power without hunting for discontinued originals.

Dual-bay charger with swappable plates

The LTD2 charger powers two batteries simultaneously and shows charge level on an LED display. Micro-USB and USB-C inputs accept common 5 V 2–3 A adapters, while interchangeable plates let the same unit handle other battery families. A short Micro-USB cable is included for immediate use.

Limited to 7.4 V Li-Ion chemistry

The charger outputs 8.4 V at 800 mA per bay, so it cannot charge higher-voltage packs or chemistries such as Ni-MH. Compatibility is restricted to the listed NP-FM and NP-QM models; cameras requiring different form factors or proprietary communication will not work with this kit.

Questions about this item

What USB inputs does the LTD2 charger accept, and what output current does it deliver per slot?

The charger takes Micro-USB and Type-C at 5V 2-3A input, and outputs 8.4V 800mA to each of the two slots.

What are the physical dimensions of the whole kit, and does the charger use interchangeable plates?

The packaged kit measures 5 by 3 by 3 inches, and the charger can swap plates to fit different battery models.

How do you start a charge cycle, and what mistake causes the charger to show no progress?

Insert batteries, connect a 5V 2-3A source to Micro-USB or Type-C, and press the mode button if the display stays blank — skipping the button press is the common error.
