Three-battery kit with USB charger

This kit supplies three 7.4 V lithium-ion batteries rated at 2400 mAh each, together with an LTD2 dual-slot charger. It is aimed at photographers using compatible Sony Alpha DSLR and SLT bodies who need spare power for extended shoots.

Replaces Sony NP-FM500H cells and BC-VM10 charger

The batteries match the NP-FM500H and NP-FM500HN form factor, while the charger substitutes for the BC-VM10 and AC-SQ950 units. The jump is worth it when a shooter wants to charge two cells simultaneously from any 5 V USB source instead of relying on a single-bay AC adapter.

Sustained charging from 5 V USB input

The charger accepts 5 V at 2–3 A through 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 the user can monitor progress during long studio sessions or location work.

Questions about this item

What physical size are the Kastar NP-FM500H batteries so I can check they fit my Sony camera?

Each battery measures 5 by 3 by 3 inches and matches the Sony NP-FM500H form factor used in the listed Alpha and DSLR models.

How do I install the batteries into the LTD2 charger and which step is commonly missed?

Slide each battery onto the charger plate until it clicks; the step often missed is aligning the contacts before pressing down.

When will the 2400 mAh Li-Ion cells need replacing and how can I tell?

Expect 300 to 500 full charge cycles; replace when the LCD shows significantly reduced capacity or the battery no longer holds a full 7.76 Wh charge.
